Sparrow Phase Already!

by Carl Strang

The last of the warblers still are shaking themselves out of the North, but there is no question that the migration season is shifting into its later stages. This week, sparrows appeared at Mayslake Forest Preserve in an unambiguous signal of the season. The prairie garden north of the chapel attracted a mix dominated by white-crowneds.

There also were some Lincoln’s sparrows, the first I’ve seen at Mayslake.

Unphotographed but also present were a swamp sparrow, a number of white-throateds, and (death knell for the warm season) the first juncos. Also unphotographed were my first Mayslake rusty blackbirds, still half in black feathers, half in their new winter browns as they foraged in the stream corridor marsh. Other migrants have been a presence for some days, now.

Yellow-rumped warblers have been abundant, showing their wide ecological range as they forage for insects on the ground, in the trees, in mid-air sallying flights, and also gulp down cedar berries.

Cedar waxwings likewise have been feeding on both insects and fruits. Here a few engage in plumage maintenance.

Enjoy this diversity while you can. Winter is coming!

    Carl,
    I got my first Tree Sparrow down in Chicago towards the end of last week and the Juncos just keep on increasing in number. Get out the snow shovels! I’m hoping we’ll see you on the Christmas Count,

    Linda
