We’ve had a good fall and early winter for both Long-eared and Short-eared Owls at Montrose. Multiple birds have been recorded during this period, though Short-eareds were and usually are more numerous. This Long-eared Owl looked comfortable roosting in a stand of cedars. It’s hard to say if this individual is a recent migrant or an overwintering bird that’s been around for a few weeks. December 22, 2022.
If you were lucky enough to be at Montrose Dunes on the morning of November 10, you were treated to a dazzling aerial display of Short-eared Owls. Up to 5 were swooping, circling, and floppy flying over the Dunes and Lake Michigan. Most eventually settled down in the Dunes and disappeared from sight. This is about as many Short-eareds as we see at one time at Montrose. It’s also a reminder that November is an excellent month for owls. More photos of this morning’s Short-eared Owls are at my eBird checklist, URL below.

November is known for rare waterbirds but it’s also excellent for owls. Long-eared, Short-eared, and Barn Owls have been reported at Montrose this November and Northern Saw-whet is a good bet. If Snowy Owls are invading they usually start appearing around Thanksgiving. So, while you’re looking for Black-legged Kittiwakes on Lake Michigan, don’t forget to check the Dunes, woods, and shrubs for owls.
A strong cold front will pass through northern Illinois late in the day on October 12. The backside winds will be from the west on October 13 and 14. These conditions are favorable for several birds at Montrose, including Franklin’s Gulls, Short-eared Owls, and possibly American Avocets and Smith’s Longspurs. We should also see an influx of typical mid October passerines.
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 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.
