“Baltimore oriole,” my husband Chuck called out—and there it was, its orange coloring glowing so brightly in the morning sun that it seemed lit from within. The bird almost seemed to be posing for us, perching in full view on a nearby tree branch and bobbing its black head as it sang.
Al Stokie, our expert birding companion, recorded it in his notebook; it would become part of the weekly bird survey he supplies to the Chicago Botanic Garden.
We continued on our walk through a wonder of the natural world that anyone in the Chicago area can see for the price of a pair of binoculars: spring bird migration.
Every spring, small, colorful warblers fly through the Chicago area on their way from their winter homes in Central and South America to their nesting grounds in the northern United States, Canada, and as far north as the Arctic Circle. And every year, birders at the Garden and beyond delight in the sight.
“In May, you always go crazy,” said Stokie, who has become the official compiler of the Garden’s bird statistics.
But May isn’t just for experienced birders; the birds are so numerous and their breeding plumage so gorgeous that it’s a perfect time for anyone to explore bird-watching. The 385 acres of the Garden are an excellent place to start. “The Garden is a pretty well-known spot for birding,” said Jim Steffen, the senior ecologist who oversees the Garden’s bird-friendly practices and its cumulative bird list, which currently numbers 255 species.

Where to look for birds at the Garden? It depends.
“You bird the Garden at different times of the year in different places,” Stokie said. “May is warbler month, and warblers are found in the woods.” So he started us off in the McDonald Woods, in the Garden’s northeast corner. We walked along the wood-chipped path, and on boardwalks and bridges over streams and ephemeral ponds, watching for movement in the trees. It was a blustery morning. “Our problem today is going to be the wind,” Stokie said, and he was right. We saw blue-gray gnatcatchers, catbirds, ovenbirds, and that beautiful oriole. And when we got to a small forest pond, we saw a solitary sandpiper scurrying through the water on its stick-like legs.
Stokie saw far more than I did—he recorded 48 species—but we didn’t get the full-on spring migration blast of birds.
You might, though.
The peak of spring migration is typically May 10 – 20, and International Migratory Bird Day is on the second Saturday in May. Most of the warblers will still be moving through in the next few weeks, Steffen said, and there should be flycatchers, goldfinches, woodpeckers, and orioles. Around the Garden Lakes, he said, people can see wood ducks, mallards, night herons, green herons, and great blue herons.
It’s a grand sight. But along with the beauty, Steffen sees cause for concern due to climate change. Trees are leafing out earlier, before the warblers—cued by the lengthening of days—arrive. “The buds are already open, and the insects associated with them are gone,” Steffen said. “It’s messing up the synchronization.”
The best places to see birds at the Garden in spring, Stokie says, depend on the bird. Warblers and vireos will be in woodlands like the McDonald Woods and the Barbara Brown Nature Reserve at the Garden’s southeast corner. Sparrows will be in open areas like the Dixon Prairie; and shorebirds and late migrating ducks will be found in the wet areas just north of Dundee Road.
Sign up for a bird walk with an expert. Check the calendar for bird and nature walks.
Or go to any forest preserve or park. Look for people with binoculars, and ask what they’re seeing. You’ll be off and birding.
