As we slowly transition into winter, reports of migrant birds are trickling in throughout the state. Snowy Owls have been sighted in Colchester and Waterbury and researchers from Project SNOWstorm predict a “sizeable push” of immature birds this year. Snows experienced a robust breeding season in the eastern and central Canadian Arctic this summer which may lead to more sightings as winter progresses. These young birds sometimes wind up in trouble and end up at the Center for Wild Bird Rehabilitation. This season we have already seen a young female who was in distress and emaciated. Unfortunately, the bird did not survive but samples will be sent to Project SNOWstorm in an effort to better help the species as a whole. Blood work will also be collected from any others that end up in rehab and sent to researchers in the project.
August marked the last round of mammal trapping as part of our collaborative research project with Dartmouth PhD student Kaitlin McDonald.
Our latest American Kestrel Monitoring Project is an aspect of fulfilling the VINS’ mission that utilizes our expertise in working with raptors and leverages our network of dedicated followers.
With spring in full swing we have officially wrapped up our winter raptor field season. Both Middlebury and Goodrich have been reliably checking in and sending location data for us to analyze. So far each bird has revealed drastically different movement patterns.
The last few weeks have been excellent for winter bird watching. Since our transmitters are arriving later than expected, we’ve decided to change strategies and set up standardized survey routes. While we’re mostly focusing on raptors, we love all birds and can’t help but stop and watch some of the large flocks of winter birds we’ve been seeing too.
We’re still waiting for all our materials to come in, but that hasn’t stopped us from getting in the field. We went out recently for another round of trapping with our partner from Cornell, Bryce Robinson, to find another abieticola (a subspecies of red-tailed hawks).
Similar to our prior outing, we didn’t catch a bird until late in the day. Just as the sun set over the fields, our research coordinator Jim made one more attempt before we called it a day and this beautiful bird came to the trap.
For the past few weeks, our research team has been searching for red-tailed hawks throughout Addison County in preparation for trapping. While this gave us a good idea of where to look, we quickly learned that it is important to stay flexible, and most of all, patient.
Addison County Vermont is the place to be for birders. Its mix of unique habitats draw hundreds of birds and bird watchers alike. In the winter it is known for being home to several migratory artic species including Rough-legged Hawks, Snowy Owls, and thousands of Snow Geese.
Three billion is the number of birds lost to North American populations in the last 50 years. It’s also a low-end estimate of the number of Passenger Pigeons that once lived on the North American continent. These birds were said to number so many that flights of them overhead could darken the sky. The fact that humans alone as a species were responsible for this devastating extinction is terrifying but, viewed from a certain angle, hopeful.
