I took advantage of milder days during winter and early spring to teach new assistants the fine art of bird extraction from mist nets at my feeder. I hoped to capture some birds we never see in our nets on Wing Island, such as Pine Siskins and Common Redpolls. On 2 March, 23 birds of 10 species were handled with just 1 1/2 nets open for 2 hours in late afternoon. Two chickadees were recaptures from last year and the rest were new birds. I was fortunate to capture 3 redpolls. What handsome birds!
I had hoped for the possibility of a Hoary Redpoll to be in the flock but no such luck. The longer and more acutely angled bill shown below
and streaked undertail coverts
along with heavily streaked back pointed towards Common Redpoll. Bill lengths were long too compared to Hoary.
Five Downy Woodpeckers were banded this day, with 4 being SY (second year) birds.
The last Downy, however, appeared with 2 isolated juvenal looking primary coverts (first and third from the outside) indicating a possible 4Y (fourth year) bird, but I will likely age it as an ATY (after third year) bird for the banding lab.
Eastern Bluebirds have been busy chowing down on my 'birdy bread pudding' made from a mix of lard, chunky peanut butter, and cornmeal including this SY female. She had a molt limit in the greater coverts (those feathers in the middle of her wing), molting the inner 4 feathers and retaining the rest.
Another clue to her age as a SY bird is the retained juvenal outermost primary covert which presents with wide white edging around the feather.
Three of the chickadees presented with leucistic feathers, those lacking melanin, one with leucistic secondary flight feathers, one with the outermost tail feather on each side, and one with half of the tail leucistic. This bird had lost half of the tail and may have undergone some stress as it's new feathers were growing in.
This Tufted Titmouse, in the same family as the chickadee, Paridae, looks quite innocent as I took the picture, but certainly didn't appreciate the banding process, squawking and biting me the whole time!
One lonely junco showed up in the mix, a handsome ASY (after second year) male.
This beautiful ASY male Eastern Towhee with it's gorgeous red eyes, sung the whole time I banded it, what a treat for me!
Judith was so happy to capture her first Tree Swallow, a species we occasionally band. This bird was eager to get back to its mate, wings flapping repeatedly as I tried to take a picture, so I put him in the bander's grip and settled for a face pose.
Thanks to Judith Bruce, Stew and Margo Goodwin, and Ron Hunter for helping with the banding the past two days. Rain is coming in so hopefully I'll get back to the nets soon. Birds seen, heard, or captured on 21-22 April are shown below. Of the total birds handled, 14 were recaptures from previous years, the oldest being a 3 yr old chickadee and Blue Jay. Numbers reflect captured birds only.
