Winsor Dam and Quabbin Gate 5

I made it over to Winsor Dam again to get a more accurate number of robins roosting in the area. The real movement started at 6:55 and largely ended by 7:15. My total amounted to 4600+ American Robins. Most were moving south or southeast. I also had a handful of Hooded Mergansers, a few Bald Eagles and a Common Loon at gate 5. In addition to these birds I had a Winter Wren singing a half song several times mid morning at home. It appears the temp's in the mid 40's inspired a bit of song on his part.
