Hi Everyone!
Yesterday while watching the birds in my backyard, I noticed that a *Nuttall's Woodpecker *was drinking from my hummingbird feeder. I had never seen this behavior before so thought I would share.
And, for all you backyard birders who would like to participate in the SCVBA Birdathon <https://scvbirdalliance.org/birdathon> (which supports SCVBA education programs), I am hosting the team "Backyard Birds and Coffee <https://scvbirdalliance.org/event-calendar/birdathon-backyard-birds-and-coffee>". You can bird your own backyard, your neighborhood or local park in the morning then the team will meet for coffee at 1:00 that afternoon to socialize . I need as many backyard birders as I can get!

Thank you for being a member of South Bay Birds [SBB]. This is our monthly reminder sent to the list with information about the group.
South Bay Birds [SBB] is a list intended for reporting the interesting birds you find in Santa Clara county, in order to help your fellow birders see them as well. We encourage everyone to share where they bird and what they see. Please include the general location (e.g., an eBird hotspot) and, if appropriate, the bird(s) of interest in the subject line, with any additional detail needed in the message body. If you use eBird, we encourage you to include a link to the eBird trip report that you filed.
This list is maintained by the Santa Clara Valley Bird Alliance ( scvbirdalliance.org) ( https://scvbirdalliance.org ). Their volunteers and funding keep the list running so please consider joining or donating to them. SBB's Lead Admin is Jim Dehnert. Chuq Von Rospach, Brooke Miller, Matthew Dodder and Barry Langdon-Lassagne assist Jim. You can contact the administration team with your questions and concerns at southbaybirds+<owner...>
The home site for this list is https://scvbirdalliance.org/siliconvalleybirding and you can find out more about us there. To start sending messages to members of this group, send email to <southbaybirds...>
The birds we watch should be our primary concern. As birders we need to be sensitive to their needs and not do things that put the birds or their habitat at risk.
We believe all birders should act as ethical birders. Your personal year list or that special photograph could put the bird at risk or cause its nest to fail. Because we expect all birders to act ethically around the birds that bring them joy, we expect that of the birders who are on our list as well. We have written up some ideas of what it means to be an ethical birder, and list links to other resources on ethical birding as well. Please read them and act to put the bird’s needs ahead of your own. If we find out that members of the list are putting birds or their habitat at risk, those members may lose access to the mailing list and its resources.
We also believe that members of the list should treat each other properly. If a list member is found to be attacking or harassing other list members, or engaging in activities that violate the ethical birding code it may affect their future ability to contribute to or subscribe to our lists.
*Acceptable Content*
The primary content for SBB is reports of interesting birds you saw and where you saw them ( https://groups.io/g/southbaybirds/message/24065 ). The objective ( https://groups.io/g/southbaybirds/message/25078 ) is to help other birders interested in the birds you saw to find them themselves. Please include the general location (e.g., an eBird hotspot) and, if appropriate, the bird(s) of interest in the subject line, with any additional detail needed in the message body. Please report only Santa Clara County locations -- other counties have their own mailing lists for trip reports.
Occasionally the administrator will post an Advocacy digest -- no more than once a week, and more typically much less often. This digest contains topics that are not typically posted to the list but we feel are of interest to the readers of SBB and are important enough to warrant posting to the wider audience. These messages will be tagged with the word "Advocacy" in the subject so members who aren't interested can delete or filter them if they choose. Topics posted as Advocacy messages typically include updates on important Advocacy activities by Santa Clara Valley Bird Alliance (SCVBA) and SCVBA volunteer activities.
*Unacceptable Content*
Do not disclose information that identifies the location of nesting birds of any species, to minimize stress on the nesting birds and the risk of vandalism or abuse.
We discourage general discussion and questions on South Bay Birds, for that we've created a Facebook group (see below). If you wish to propose a general-purpose announcement for an Advocacy digest post, please send the proposed text to the administrator (below).
Please do not post notices of upcoming events to SBB. There is a sister list, South Bay Birds (Events) [SBB-Events], that should be used for that purpose. If you are interested in knowing what events are being offered by SCVBA and other county bird-oriented organizations, we encourage you to subscribe to this list (see below).
Please do not post carpooling requests for events to SBB. We request that they go to the Facebook discussion group.
*Unsubscribing from South Bay Birds*
If you ever need to unsubscribe from this list, an unsubscribe link is at the bottom of every message, or you can go to https://groups.io/g/southbaybirds/. That's also where you can view the list archives, set up a vacation hold, change your email address, or modify your subscription in any way.

Hello SBBers, Maybe of interest to the group: While camping this week at Coyote Lake, I observed what I believe to be a dilute leucistic bald eagle. I saw it only once, near the tent campsite and managed only a few poor photos checklist/S313769629 <https://ebird.org/checklist/S313769629> as it flew to the far side of the lake. Adult with an all white head, all yellow beak, and mottled pale tan coloring (like a white latte).

Hi Birders,
We walked from the Stevens Canyon, Redwood Gulch intesection up stream on Stevens Creek for one mile. Discounting many Steller's Jays, there were not a lot of birds. We did encounter three notable early migrants: 1 male Black-headed Grosbeak, 4 Western Warbling Vireos and 3 Western Flycatchers.
These three species were singing or calling. We heard-only the Western Flycatcher, we saw one of the Western Warbling Vireos, The Black-headed Grosbeak was heard and seen at Stevens Creek Bridge no. 37C0604 where we have often encountered this species in previous years.

Hi Everyone!
It's getting birdy out there! I was walking with my mom at Rancho Cañada
del Oro and heard my FOS *Black-headed Grosbeaks* right from the parking
lot. I assume March is very early for them because ebird marked them as
"rare". Along the Longwall Canyon trail, I heard my FOS *Cassin's Vireo*.
Lots of other birds were singing but I didn't spend the time to id all of
them. Here's my incidental ebird list:

Good day birders,
I read Lisa Meyers post and want to tell you that today I was coming home from birding around Guadalupe Oak Grove where I got my target bird the Hooded Oriole. In thirty minutes I had 23 species.
I decided to go to Lake Almaden to check on things there. Those who know me know why I go on a daily basis.
While stopped at the red light at Coleman and Almaden Expressway I saw the gulls were all over the sky. Looking from the inside of my car I spot the Bald Eagle. I believe it was the 4th year female.
I am now hanging out the window to take photos. All of a sudden from my right flying low over Almaden Expressway to Lake Almaden was the male Bald Eagle. The sky was loaded with gulls now. What a treat!
I was never so happy for the 5 minute red light!
I went into Lake Almaden to park my car and to check on things and bam…. The Bald Eagle is over the lake. I told a couple and they were so thrilled to see a Bald Eagle in our neighborhood.
Hoping to spot this bird for my SCVBA Birdathon day on April 24 for the Almaden Eagles.

Hi all!
I usually strike out at Sanborn Park, but this morning the area above the Sequoia parking area was crawling with warblers!
I never left the paved trail, but walked down the hill first area where I heard and saw my first of five Townsend’s Warblers and one singing Wilson’s Warbler.
A bus dropped off 50 screaming students, but that didn’t deter the warblers. Near the top of the hill I was trying to get a good look at any of the three Townsend’s overhead, when I found myself face-to-face with the bright yellow head of a Hermit Warbler!
I sat on the bench near the small cement pond at the top of the hill and watched a silent Black-throated Gray Warbler fly to a bare oak tree near the giant redwood grove.
Brown Creepers and Purple Finches were also singing this morning, as well as Western Flycatchers.
I might add that I was not disappointed not to find Yellow-rumped Warblers! But unfortunately the construction noise is still omnipresent at the park.

Good afternoon, SBBers, Today we lucked out and the weather was just right! Fourteen birders met us at the Marina parking lot of Lake Cunningham park. It was a bit cool, just a little wind, hardly any clouds and a lot of enthusiasm as we started out on a 30 species day. A chorus of Great-tailed Grackles greeted us as Tree Swallows and Cliff Swallows darted overhead and California Gulls started to arrive from the Kirby Canyon landfill. We checked out the wells in the pepper trees, but no sapsuckers were feeding today. *Sigh* Spring was in the air with American Coots battling it out, Pied-billed Grebe displaying to each other, and a male Common Yellowthroat singing his heart out to an unknown lady love along with a couple of other Common Yellowthroats. Maybe they were all competing for the same lady love!!? Bushtits were busy in pairs gathering nesting material and catching a snack here and there. White-crowned sparrows were in abundance and singing rambunctiously. I suspect they are from the south and beginning their migration northward, but stopped by the Native Garden to "tank" up before their northward journey. A Green Heron did a very quick flyby and did not linger. Darn! It was not easy but Eve helped find a Hooded Oriole at the very top of a Eucalyptus tree and earlier helped find a Red-winged Blackbird, lurking in a tree. A Red-tailed Hawk dramatically swooped amongst the trees in the Native Garden taking us for a nice surprise. Two Song Sparrows who were obviously a pair entertained us up with their tender interaction. Ahhh, Spring. Here is the checklist for today. eBird Checklist - 22 Mar 2026 - Lake Cunningham Inner Lake Path, San Jose, California, US (37.334, -121.81) - 30 species (+2 other taxa) <https://ebird.org/checklist/S312221837> My thanks to Eve Meier who helped attendees identify birds and Arvind and Ashok who took over the botanical duties of the trip.

This morning was a beautiful morning at the Los Gatos Creek and Oka ponds. We enjoyed the sights and sounds of many birds and saw lots of breeding activity. From a Nuttall's Woodpecker drumming and Anna's Hummingbirds doing their diving display, to an American Crow breaking off branches to build its nest. Along the creek, we observed 3 Anna's Hummingbird nests in various stages of use. One was empty from a successful fledge over a month ago, another was being actively sat on, and the last was in the very early stages of nest building. We were also delighted with an active Bushtit nest with a familiar egg filled sag and a parent seen entering.
The ponds had a few small flocks of straggling winter ducks and a few dozen swallows filling the air. Over and around the ponds, Northern Rough-winged Swallows were feeding and even seen gathering nesting material from the ground. The Cliff Swallows were already busily visiting the underside of the creek bridge, where they nest every season. We also saw and heard our first of the season Hooded Orioles, including a male, female, and a first-year male inspecting the palms along the creek. In total, we identified 53 species, 26 of which had breeding behavior codes. Here is a copy of the checklist https://ebird.org/atlascalifornia/checklist/S312132317 ( https://ebird.org/atlascalifornia/checklist/S312132317 ).

Thank you everyone for joining Philip, Sarah and I early this morning. Everybody pitched in and helped find, identify and help others find birds...Thank you. It was a fantastic trip today and did not disappoint with the arrival of some of the spring birds. When we first arrived a low mist hung over the valley and the birds soon appeared on all sides. In fact there were so many birds it took a quite a while to make it to the base of the hills. Here is a link to the full list. https://ebird.org/checklist/S312199306
We started with a good look at the Laguna Seca pond at the other end of the valley through some scopes where we saw some Great Egrets, Green-winged teals, Greater Yellowlegs with several flyovers by the Egrets and Great Blue Heron. Red-wing Blackbirds and Western Meadows kept popping up out of the thick grass to fly to the tops of nearby trees as we moved along. We were constantly surrounded by a loud chorus of Red-wings for the entire trip which was very different from the last trip where we had ZERO (December). American and Lesser Goldfinches flew among the willows next to the creek. We flushed a Wilson's Snipe and had some good looks at a Yellow-billed Magpie sitting 2 ft from a Sharp-shinned Hawk at the top of an oak. We then hit an oak tree that was the social spot for many species: Northern House Wren, Yellow-rumped Warblers, Western Bluebirds, Acorn Woodpeckers, Lark Sparrows and the newly arrived Western Kingbirds while Tree Swallows flew overhead. The Red-tailed Hawks and American Kestrels flew along the top of the hill looking for food. A Bullock's Oriole also very briefly appeared. We saw several instances of gathering nest material from Northern Mockingbirds and courtship behavior from Wild Turkeys, Red-winged Blackbirds and the Kestrals.
A patch of Plantain and Serpentine rocks were seen along the trail and a field of spider webs spread low to the ground. And the Buckeye ( https://www.inaturalist.org/guide_taxa/358044 ) Butterfly!

Peg, Diane, Zainab, and I had a delightful, blue skies, sunshiney morning today on the Bay at the drop-in event we hosted at the Charleston Slough in Mountain View. ~25 birders and bird-curious community members joined us as we got to revel in:
- some favorite wintertime visitors that will be heading home soon (Northern Shovelers, Green-Winged Teals, Canvasbacks)- frequent (and welcome) interruptions by the returning Barn Swallows - Cliff Swallows scoping out a potential nesting site on the underside of the nearby wooden structure- a pair of Northern Harriers circling high above- Snowy Egrets showing off their delicate breeding plumage - an endearing display of American Coots scurrying down the mudflats into the water- American Avocets in transition to their striking orange breeding plumage- first-of-season Brown-Headed Cowbird (yikes!)- House Finches gathering and depositing nesting material- a flock of American White Pelicans that appeared in time to bid us adieu at the end of our event

I went to John Nicholas Trail this morning hoping to find a Wilson’s
Warbler. I heard one as soon as I parked my car in the parking lot on Black
Road, but I proceeded to take the trail to Lake Ranch Reservoir to see what
else I could find. There were eight more Wilson’s Warblers singing along
the trail to the lake, and at least four at the lake. Other spring migrants
singing along the trail were Western Warbling Vireos and a Western
Flycatcher.
At the lake, near the far picnic table, there were two Cassin’s Vireos in a
willow tree and a Black-headed Grosbeak singing nearby. Other highlights at
the lake were a pair of Hooded Mergansers and an adult Bald Eagle catching
and eating a fish.
When I got back to my car, I heard another Cassin’s Vireo.

- The lovable ruckus of the local Acorn Woodpecker family
- Up-close views of the White-Breasted Nuthatch and the Pygmy Nuthatch (while not simultaneously, still great for a size comparison)
- A lone Bushtit that was uncharacteristically was exploring the ground by the feeders
- The startling rattle of a male Nuttall’s Woodpecker

Hi Everyone!
Today Edward Rooks, Bill Albrets and I led a SCVBA field trip at Coyote Lake, one of my favorites! Highlights at the campground were watching the pair of *Oak Titmice* working on their nest in the valley oak in the parking lot, watching the very gangly *Great Blue Herons* land at their nesting site and seeing them on their nests, finding the *Red-breasted Sapsuckers* in the peppertrees (and other trees), and watching the *Double-crested Cormorants* trying to cool down in the heat. At the dam, the highlights were the *Bald Eagle *on the nest, the *White-throated Swifts* zipping above us and the surprise pair of *Wood Ducks*. Several pairs of grebes, mostly *Western Grebes*, were "rushing" across the water. After the trip, the *Rock Wren *showed itself. We never did see the Canyon Wren (my third try)!

I was with a group birding at Coyote Lake just yesterday. After much patience we observed both the *Rock and Canyon Wrens* at the dam. Neither were singing, so we had to spot them as they popped out of the boulders. It was a lazy morning and we spent a lot of time hanging out at the damn. And the *White-throated Swifts *were very active at the dam offering great views.
The *Red-breasted Sapsucker* was very cooperative as it hung out in the Pepper Tree located on the north side of the entrance to the campground amphitheater.
We also had *Bald Eagles* and a *Golden Eagle*.

Santa Clara Valley Bird Alliance is an official founding sponsor of the California Bird Atlas. On page 14 of the recent spring issue of the AVOCET, Barry Langdon-Lassagne wrote an excellent summary of how to participate in the atlas project by configuring your mobile phone. I encourage you to take a look at it and start submitting your eBird reports to the atlas by joining the project on the app’s start screen.
We will also have Van Pierszalowski as our guest on Speaker Series soon. Stay tuned!
Finally, spring migrants have begun to appear at the Ranch. Last week several Western Warbling Vireos showed up along side a few Northern House Wrens. Today I heard the first Hooded Oriole in the fan palms. Today is also the first day in months I have not heard Ruby-crowned Kinglet or Yellow-rumped Warbler from my office window. There have been no signs of Western Flycatcher, or Black-chinned Hummingbird at the Preserve yet, but any day…

I saw a Golden Eagle at 1:30 pm today. It flew out of a large oak tree at Almaden Meadows Park, a hilly park at the intersection of Meridian Avenue and Camden Avenue in San José. It headed off to the northeast.
This is also a great spot to study Acorn Woodpeckers.

Amanda and I enjoyed a sunny spring morning with 9 beginner birders on our 1-hour walk along Lake Cunningham in East San Jose. Ahead of the heat predicted for today, we were delighted by a soothing lakeside breeze, a continuous hour of birdsong, and great views of:
- male Ruddy Ducks ensconced in their breeding plumage with their baby blue bill- a Common Yellowthroat giving us a witchety-witchety vocal and visual display at the base of the native garden- American Coots chasing after each other on the water’s surface and some feet on display when they wandered ashore- an island of American White Pelicans and Double-Crested Cormorants- a squad of American Crows dive-bombing a possible juvenile Red-Tailed Hawk- several trees bustling with Yellow-Rumped Warblers- a Green Heron in flight across the lake- an actively munching flock of Cedar Waxwings to close out the trip
A lovely March morning with lovely birding company!

Hi birding friends,
Bob Bolles and I lead a delightful and enthusiastic group of birders on a trip along Penitencia Creek Trail in Alum Rock Park this last Friday the 13th. Our group had some new birders and some more advanced birders. Just as we started out, we found California Quail feeding on the hillside, a Brown Creeper feeding on an oak, several Acorn Woodpeckers, and heard a calling Nuttall's Woodpecker. As we moved along, we heard a could of trilling Bewick's Wrens and observed a solo Red-tailed Hawk circling above.
Farther down the trail we saw a few Bushtits, Chestnut-backed Chickadees, and Oak Titmouses. Near the Inspiration Trail junction, we observed our first White Breasted Nuthatches. The pair were very active and seemed to be moving about their nest. We entered the park main area where we saw some Tree Swallow feeding. From here near the first bridge in the park, we observed an Oak Titmouse entering its nest hole. This created quite a bit of excitement. Moving deeper into the park we listened to the calls of mobs of Steller's Jays chasing each other through the trees.
Looking into the creek a male Mallard was swimming solo, most likely looking for a mate. Looking up toward the ridge line at Sierra Vista we saw a kettle of Turkey Vultures circling above with a pair of Red-tailed Hawks. THhs seemed to be the pair we saw mating in a dead eucalyptus snag earlier. This might have been the highlight of the trip. While looking in the ridge direction we were able to watch Band-tailed Pigeons fly into a tree on the lower hillside.
Return, we saw many of the same birds. The new species we were able to enjoy darting about were four Northern Rough-winged Swallows seeming to be looking for food of nesting areas under the bridges.
When we returned we saw another Red-tailed Hawk land on here nest in the eucalyptus above Eagle Rock Parking lot. It was a fun day with really fun and kind people. Looking forward to leading a trip once more. I am grateful to Bob Bolles for his help and knowledge making the trip very fun. Thank you everyone who attended, you all make a difference. (check the eBird List to see all the birds we observed)

Hi Everyone!
Yesterday, Melissa J and I visited Coyote Lake. Fun sightings at the campground were a couple of *Red-breasted Sapsuckers* on the peppertrees, a pair of *Western Grebes* performing the weed ceremony and nesting *Great Blue Herons*. At the dam we had a *Bald Eagle*, a *Golden Eagle*, *Rufous-crowned Sparrows*, *White-throasted Swifts* and a *Rock Wren *but no Canyon Wren.
I did a brief walk at Stiles Ranch this morning. The poppies are just starting to bloom. I was able to find one male *Rufous Hummingbird*, a few *Horned Lark* and *Rufous-crowned Sparrows*.

As I drove down Fortini at 8:30 this morning I heard the call of a BULLOCKS ORIOLE. I stopped and found a bright orange and black male high in a Sycamore. A WHITE TAILED KITE pair was perched on snags here and some WESTERN BLUEBIRDS were along the wire.
I birded north or west along the Calero Creek trail and shocked when a vocalizing PILEATED WOODPECKER flew in from the orchard and into a tall Valley Oak along the creek. I couldn't find it in the tree but after some prompting it flew out towards the Santa Teresa Hills and disappeared. A LARK SPARROW was singing in a small tree here.
Our neighborhood WHITE TAILED KITE attracted a mate the day after I reported it but she disappeared later the same day. He's still atop the same tree but not calling as much. photo

The one note call of a WESTERN FLYCATCHER was heard as I parked near the
Calero Creek trailhead this morning. It was perched in a willow over my
car. I saw three WARBLING VIREO in two locations along the trail. HOUSE
WRENS were seen or heard in four locations.
RUBY CROWN KINGLET'S were all along the trail as were many NUTTALL'S
WOODPECKER. I had a pair of HAIRY WOODPECKERS at the start of the trail
and male at the bend. Three DOWNY WOODPECKERS were chasing each other at
the far end of the orchard.
A male AM. KESTREL, RED SHOULDERED and RED TAILED HAWKS were seen. Six
WESTERN BLUEBIRD pair were in the orchard. A calling WOOD DUCK pair
circled over the orchard several times.
RUFOUS CROWNED SPARROW'S sang on the hillside after the creek crossing
and one unidentified bird perched on a rock on the ridge may have been a
Western Meadowlark. CAL. THRASHER, WRENTIT and CAL. QUAIL were heard
along the chaparral hillside where I turned back.
Many OAK TITMICE, CHICKADEE'S and BUSHTIT'S were seen as well as one
Bushtit nest.

Yesterday we took advantage of the beautiful weather and cycled to the Bay along the Stevens Creek Trail. We discovered that at the A2W Song Sparrow Spur Trail is now open. It features about 1.5 miles of level, hard packed gravel and wonderful on bike or foot. This pond has not been accessible in my memory but now provides birders a great opportunity to search for Waterfowl and Shorebirds as the mudflats at the dead end are extensive. It is probably best accessed from the Kite Flying (Parking Lot E) of Shoreline Park, but still requires a long walk to the trail head.
Without a scope it was hard to identify the many thousands of birds that were present, but we did pick out Hudsonian Whimbrel, Long-billed Curlew, Dunlin, Western and Least Sandpipers, Black-bellied Plover, American Avocets, Black-necked Stilts and perhaps others to far to be sure. We also observed both Western and Clark’s Grebes displaying and dancing together as well as Eared Greb, Greater and Lesser Scaup, Common Goldeneye, Canvasback, and Ruddy Ducks. We will definitely investigate this area again during fall migration but I’ll bring a scope.

Hi Everyone!
Today Peg Albrets, Bill Albrets and I hosted a drop-in birding session at McClellan Ranch. For those of you unfamiliar with a drop-in, SCVBA volunteers are stationed at one location and attendees can drop by anytime during the time that we are there. They can stay for as little or as long as they would like. We were there for 2.5 hours today and spotted and/or heard 34 species while talking birds and enjoying the weather from our seats at the picnic table. The highlight was a flyover *Osprey*. But we also saw a pair of *Red-shouldered Hawks* and a *Cooper's Hawk*. Birds at the feeders included the group of *Dark-eyed Juncos*, *Pygmy Nuthatches, White-breasted Nuthatches, House Finches, Song Sparrows, Golden and White-crowned Sparrows, and a Nuttall's Woodpecker*. See our ebird list for a complete list.
Peg and I are hosting a "Backyard Birds and Coffee <https://scvbirdalliance.org/event-calendar/birdathon-backyard-birds-and-coffee>" Birdathon Team on Sunday, April 12th. Everyone will bird their own "backyards" to see how many birds we can find as a team. Afterwards, for those who are interested, we will meet for coffee (and cookies) most likely at Peet's in east Los Gatos.

Good afternoon, Birders, On a fairly windy day, Dan Bloch and myself met with 11 experienced birders and 3 birders who have birded for 1-6 months only. Thirty-five species were seen in spite of the fact that most of them were trying to stay out of the wind! The Barn Swallows did not do a "fly by," they did a "blow by." The pair of Bald Eagles seen by Kirsten earlier today probably stayed in Sunnyvale Baylands Park or got blown to Morgan Hill. The nest-building skills of Marsh Wrens were clearly demonstrated; at one point about 7 nests were counted in a small area and we wondered how many were actually occupied as several wrens were seen popping in their side doors. The Northern Shovelers were looking pretty spiffy and a lone handsome Ruddy Duck was beginning to get his blue bill. Ahhh, Spring is here! Seeing two Green Herons gave the new birders a real treat. Snowy and Great Egrets along with a Black-crowned Night Heron were very patient while very obligingly posing along the tules. A Red-shouldered Hawk, looking a little scruffy, secreted itself in a bare tree. A lone Western Gull among a bunch of California Gulls allowed a good size-comparison between the two. And while looking at gulls we spotted a Muskrat swimming diligently in the slough and watched as it snatched a tule leaf and dove underwater. Only to be seen on another special occasion! My thanks to Dan for keeping the eBird list and here it is....... https://ebird.org/checklist/S306024221 Join the Birdathon, Vicki Silvas-Young

It was actually a good morning for raptors generally today. A MERLIN was hanging out at the main playground. An adult COOPER'S HAWK has been hunting around the boardwalk for a few days and is likely a good part of the reason why the WILSON'S SNIPE have been absent for that time. On Monday, I saw a number panic fly away as the hawk hunted over the marsh around the boardwalk.
The usual pair of AMERICAN KESTRELS were strung out behind the marsh fencing. Meanwhile, a WHITE-TAILED KITE was busy trying to bother a pair of COMMON RAVENS away farther out.
A RED-SHOULDERED HAWK has seemed interested in setting up house behind the Indian Grass area. It has been very vocal in the mornings.
In more ambiguous feeling news, a pair of AMERICAN CROWS was carrying nesting material into a tree in the neighborhood of the Burrowing Owl area.
Enjoy,
Kirsten
