I walked the bike path from Niskayuna Lions park past the Ferry Drive bridge today from 12:20-2:00pm.
The area between Lions Park and the Ferry Drive Bridge was quiet with only a little open water in the middle of the river.
Past the Ferry Drive bridge the birds were more active including:
Sharp-shinned Hawk- a nice view of a perched adult bird just past the bridge
Bald Eagle- an adult perched near the river
Snow Buntings-50 or so in an active group in the farmers fields north of the Ferry Drive bridge
American Tree Sparrows-20 in a group
Common Raven- 1 bird flying over the bridge croaking and diving in the brisk winds
