Mayslake’s Winter Birds

by Carl Strang

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.

This warbler often chowed down on the berrylike cones of red cedars.

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.

I didn’t see the jays feeding, but there was a good acorn crop last fall and my guess is that the jays stored a sufficient supply.

Some winter residents were steady, and expected. These included cardinals

and juncos.

Mayslake’s juncos wandered widely, and I never got a sense of how many groups there were or how their home ranges were distributed.

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.

I saw white-throated sparrows so seldom that I think they were wanderers rather than residents.

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.

Sure enough, the male had a band on his left leg. I take it that this is the same pair that nested successfully on the preserve last year. I saw no sign of the two surviving young that were with this pair the last time I saw them in the fall.

I am so ready for spring and the progression of migrants. Bring it on!
