That’s really so cool Diane. I wish all the travelers safe passage. Each one such an individual.

The Cayuga Bird Club operates two Motus stations for detection of radio-tagged migratory birds -- one receiver at Myers Point and the other atop Mount Pleasant. See https://motus.org/dashboard/#e=profile&d=projects&s=301 for a complete list of all 27 species (41 individuals) that we have detected since 2019.
This fall our Motus station at Myers Park has detected 3 migratory birds and our station at Mount Pleasant detected 2 birds and 2 Silver-haired Bats!
The furthest flying migrant was a Wood Thrush, tagged in Honduras last March. It was detected in Georgia in April but then disappeared from the Motus network during the summer months. It reappeared, flying past our Mount Pleasant station on September 27 and continued south, last reported in Georgia on October 10. It will be interesting to see if it continues on to Central America.
The detection of a migrating Least Bittern at Myers Park was a nice surprise, as it is not a commonly seen bird here. The Least Bittern that we detected was tagged in Quebec in the summer and then It is interesting to note that there is a report from a night flight call session, also on September 12, recording two Least Bitterns flying over Palmer Woods.
Two Sharp-shinned Hawks tagged at Braddock Bay on Lake Ontario last April were detected this fall, one by each receiver, just 1 day apart from one another.
New for our Motus project was the detection of two Silver-haired Bats. Silver-haired bats are a migratory species of tree bats that nest in tree cavities or behind bark, and move to warmer habitats for the winter. These bats were tagged on the north shore of Lake Erie near the end of August, and detected about a week later by our Mount Pleasant receiver. See the zig-zagging path of one of these bats here: https://motus.org/dashboard/#e=profile&d=animals&s=66909.
Below is the list of our Fall Motus detections this far. There is a lag between data upload and appearance on the Motus website, so it is possible that we will soon learn of additional hits by our Motus stations. Each of these detections helps researchers to better understand the timing and trajectory for individual birds of different species (and other animals!)
9-7-2025 - Silver-haired Bat (Mount Pleasant)
Release date: 9-2-2025, Lake Erie
8-26-2025 - Silver-haired Bat (Mount Pleasant)
Release date: 8-19-2025, Lake Erie
