A male Red-winged Blackbird surprised me on February 15. It seems a little early for them, but Red-wingeds didn’t (and usually don’t) winter at Montrose, so this bird has to be a migrant. Along with Red-wings, other early spring passerine migrants we should start seeing in the next couple weeks include Horned Larks, Song Sparrows, and Eastern Meadowlarks. Waterfowl diversity will also pick up during this period. Check weather reports for warm fronts and south winds as these are the conditions that bring in spring migrants.
As expected, the strong south winds brought a lot of migrants to Montrose Point on March 30. I ended up with 41 species in a little over two hours of effort, and 57 species were reported on eBird by all observers. Most impressive were the numbers of Northern Flickers coming in off Lake Michigan early in the morning. These birds were migrating north over the lake at night, and when the sun rose they started to head inland towards land and safety. No passerine or other landbird worth its life wants to get caught over Lake Michigan when the sun comes up. The local Peregrine Falcons and Herring Gulls relish hunting these tardy migrants as they make their way to shore. I also had multiple first of spring sightings, including Caspian Tern, Belted Kingfisher, Hermit Thrush, and Lapland Longspur. Link to my eBird checklist for the morning below.

It’s axiomatic among Chicago lakefront birders that southwest winds in spring produce lots of migrants. Today, March 8, reaffirmed that maxim. I ended up with 42 species in a couple of hours of birding, including a number of new birds for the year. Large numbers of blackbirds and Canada Geese were moving on the south winds, and we had a number of unusual sightings. Best for the morning were
Greater White-fronted Geese – 27
White-winged Scoter – 1
American Woodcock – 1
Turkey Vulture – 1
Merlin – 1
Rusty Blackbird – 2
The favorable conditions will continue for at least three more days, so birding should be good at Montrose for most of the rest of the week.
