Two Rough-legged Hawks flew over Montrose on November 9. What’s interesting is that conditions weren’t favorable for hawk migration – overcast skies, light rain, and breezy south winds. Montrose is known for many things birdwise but we don’t do well with migrating buteos. Reasons for this discrepancy could be a lack of birders looking up for hawks and our proximity to Lake Michigan, which may scare away migrating buteos. Rough-legged Hawks aren’t intimidated by large bodies of water, which, oddly, may be the reason why we see more of them in active migration than other buteos, though they’re still rare.
April 11 lived up to the billing and turned out to be an exceptional day for migrants, with about 80 species reported to eBird. The south winds overnight brought in a lot of birds, as south winds usually do in spring. Northern Flickers and Hermit Thrushes were conspicuous by their numbers. Bird of the day goes to the nearly full breeding plumaged Eared Grebe on Lake Michigan near the base of the fishing pier. The bird was close to shore and conveniently associating with a group of Horned Grebes for comparison. Eared Grebes are rare and not annual at Montrose. Other goodies include Merlin, Short-eared Owl, Eurasian Collared-Dove, and the late continuing male Long-tailed Duck along the fishing pier. Link to my eBird checklist for the morning below.

A Black Vulture was seen at Montrose on Saturday, November 13. The bird worked its way up the lakefront from the Jarvis Sanctuary at Addison, stopping briefly near the harbor before ending up at Foster Avenue. On Sunday, November 14, it visited the Montrose Point Bird Sanctuary, roosting obligingly on a light pole for the many birders who came to look for it. This is just the second Black Vulture record for Montrose.
Black Vultures are common throughout the southern United States and range south into Central and South America. The closest they normally come to Chicago is west central Indiana, though they frequently occur outside of their regular range as vagrants, sometimes dramatically so.
Postscript: The bird was captured by wildlife rehabbers on November 14 because it wasn’t healthy.

A strong cold front will move through Chicago over the weekend of November 12 – 14. Daily high temperatures will be in the low 40s and winds will be westerly, at least for Saturday and Sunday, and in the 10 to 15 mile per hour range. This is an excellent setup for a late fall push of birds. These conditions often produce Short-eared Owls and Franklin’s Gulls, and we could see a few hawks migrating down Lake Michigan, especially Northern Harriers. Sandhill Cranes also move on these conditions, though we rarely see large numbers of them at Montrose. There’s always the possibility of something extraordinary showing up – it is November after all.
It was a Peregrine kind of day at Montrose on October 13. This juvenile perched obligingly in a snag long enough to have its picture taken. We also had an adult Peregrine, which knocked a poor migrating Winter Wren out of the sky and into Lake Michigan.
The Peregrine Falcons weren’t the only highlight. October 13 was one of the best days of the fall at Montrose for passerine migration, with lots of Swamp Sparrows, Yellow-rumped Warblers, and kinglets. Bonus birds include American Avocet and three Franklin’s Gulls. I ended up with 52 species for the morning. Link to my eBird checklist 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.
