Mayslake Migrants Late April

by Carl Strang

The migrant songbirds, and other birds that wintered in the tropics, really begin to flow into northeastern Illinois in the last week of April, and will peak in May. April 24 brought Mayslake’s first chimney swifts, brown thrasher, yellow warblers, and pine warblers including this one.

By the 27th the preserve was hosting newly arrived solitary and spotted sandpipers, green herons, northern waterthrushes, a black-throated green warbler, a blue-winged warbler, a rose-breasted grosbeak, and this Baltimore oriole,

as well as a northern parula.

The parula was singing its alternate song, for the most part, the rhythm of which reminds me of the William Tell overture and therefore, inevitably for a member of my generation, the Lone Ranger.

New arrivals on April 28 were warbling vireo, white-crowned and vesper sparrows. The 29th brought house wren, ovenbird, catbird, Tennessee warbler, common yellowthroat, and this red-headed woodpecker.

I am hoping that Mayslake’s savanna will be of interest to this relatively rare woodpecker as a nesting area. The last day of April brought a single new species but a good one, a golden-winged warbler.
