An interesting mix of bird species wintered on Mayslake Forest Preserve this season, through the storms and the cold. Among them was a yellow-rumped warbler that mainly was active around the south and east shores of May’s Lake.
There always seemed to be jays around, and sometimes when a few became agitated their calls drew in as many as 10 of their kind.
Some winter residents were steady, and expected. These included cardinals
American tree sparrow numbers fluctuated greatly, but there always were at least a few around. A common redpoll showed up one day and was gone the next. There also were rare appearances by white-throated sparrows.
Though no red-winged blackbirds have shown up at Mayslake yet, I have seen them elsewhere in DuPage County and expect some at Mayslake any day. An equally sure sign of the transitional season was the arrival of this Canada goose pair at the stream corridor marsh yesterday.
I am so ready for spring and the progression of migrants. Bring it on!
