Evening Grosbeaks have been a recent regular winter occurrence in my hometown of Marienville in Forest County, appearing during 7 of the last 11 years. With a 92% decline since 1970, Evening Grosbeak shows the steepest decrease among all continental land birds in the U.S. and Canada (Partners in Flight 2016) with little explanation as to why.
This winter the Pennsylvania Natural Heritage Program (PNHP) at the Western Pennsylvania Conservancy and the Powdermill Avian Research Center at the Carnegie Museum of Natural History are collaborating to study winter and migration movements of Evening Grosbeaks in and around the Allegheny National Forest. By color-banding and deploying nanotag radio transmitters on select Evening Grosbeaks, we aim to learn more about this species via the Motus Wildlife Tracking System and resighting banded birds.
Over the years many birders have enjoyed viewing the grosbeaks in Forest County. With the current irruption of grosbeaks this winter, birds may be encountered widely across the state, and we ask that if you observe any COLOR-BANDED or TAGGED birds, please report them to us!
When you encounter Evening Grosbeaks, especially in western Pennsylvania, pay particular attention to the legs and take note of any color band combinations and look for a long thing antenna extending from the back/rump area for any tagged birds.
Please include date, time, location (address and GPS coordinates), and most importantly COLOR-BAND combination/ NANOTAG transmitter presence.
For anyone wishing to visit the Evening Grosbeaks this winter in
1. Please contact me via phone, text, or email (#814#221#4361 or
<dyeany...>) to arrange a visit, as we are actively conducting research at the site.
2. Please view birds at the feeding station from the sidewalk near the blue spruce at the corner of the yard. Please do not enter the yard. Parking may be available at municipal lot behind the Quick-N-Easy, on-street, or at the church (if not in use).
3. Finally, please submit an eBird checklist! Share any color-banded Evening Grosbeaks with me at <dyeany...>
We appreciate any additional observations of Evening Grosbeaks from our project as we try to learn more about this declining nomad from the boreal forest!
