We’re seeing the expected mid summer southbound migrant shorebirds like Least Sandpipers and Willets, but a White-rumped Sandpiper on July 3 was a surprise. Which way was this bird going? White-rumpeds are late spring migrants; we often see a few well into June but July birds are harder to interpret. I suspect this bird is a very tardy northbound migrant since we were seeing White-rumpeds in mid and late June, and we usually don’t get southbound birds until late August at the earliest.
Even more inexplicable was a Hermit Thrush near the Marovitz Golf Course. Hermit Thrushes are early spring and later fall migrants in northern Illinois. Most spring birds have moved on by early May and the first fall birds don’t start appearing before late September. In other words, Hermit Thrushes shouldn’t be in Chicago in July. Obviously this bird is confused.
