Journal Entry #2 - Matt Joyall

For my birding excursion this week I started out with the Friday (2/19) field group with the Orno group. I was out from 1400 to 1540, it was 30 degrees F, with 30% cloud cover and a moderate breeze out of the SE. I walked from the Aiken building east towards the medical center parking and then walked around the medical center. From there, I walked back down main street to south prospect and went all the way down to swift street and then returned to maple st via south prospect. The habitats I birded in were all urban / developed areas.

Near the Davis circle center I spotted a sneaky Black-capped Chickadee peetering around in a deciduous tree. Along the way I found several American Robins scattered along South Prospect. I counted eight in total. The Robins fluttered away quickly when I approached and then curiously made their way back to me once they no longer perceived me as a threat. They hopped around the tree a lot with rapid wing movement.

I saw the American Robin use it's elliptical wings to make quick fluttering motions to move across the snow at ground level and also to rapidly push off to seek safety in a tree perch. The American Robin's flight pattern was more smooth and less choppy than the flittery Black-capped Chickadee. They both seem to be versatile moving from the ground to trees, but the Robins seem to do it more powerfully. This may be in part because they are a bit bigger and need to generate more power to move. They definitely seem to have a bit higher wing loading than the Black-capped Chickadee.
