Interesting. Timely. Cool and clever. There are a mix of happenings in Minnesota's avian community worth checking out this month (and weeks to come):
Fall migration
Eyes are skyward from the Hawk Ridge Bird Observatory perch on East Skyline Parkway in Duluth for fall migration along Lake Superior. Hawk Ridge begins its count Saturday and continues into late fall (peak time is early September through early November). Depending on the winds — north/northwesterly are most favorable — raptors can be seen by the hundreds as they work their way south, some as far as South America.
On average, Hawk Ridge counts as many as 60,000 migrating raptors and tens of thousands of other birds, from waterfowl to warblers. Sharp-shinned hawks, kestrels and broad-winged hawks are among the first species seen, and they can pass en masse: A record 2,515 sharp-shinneds were counted Sept. 24, 2017. They peak in mid-September to early October. Conversely, red-tailed hawks, northern goshawks and golden eagles will peak into November.
This fall, count director John Richardson said northern saw whet owls are of particular interest. There are markers that the species is doing well: Like Hawk Ridge, Whitefish Point Bird Observatory in Paradise, Mich., is in a migratory corridor, and has had a record summer, banding 643 owls since July 1 and 573 juveniles.
Turkey vultures and bald eagles continue in record numbers in recent years, but data shows they're moving later. Warmer temperatures in the northern territories could be keeping the birds longer, said Richardson, suggesting the effects of climate change on migratory patterns.
The cycles bring an urgency to the fall — and spring — counts.
"Just by us being there and pointing things out and talking about things is important in itself," Richardson said. "To actually have 50 years of data, some of the things are kind of eye opening, good and bad."
Richardson said thousands of people will come through during the migration, some to watch, some with questions. He said he expects even more given the flight to the outdoors during the pandemic, and he is hoping people will use common sense and take safety precautions — as he and his staff must.
