What happens when an endangered bird nests in a hayfield set to be harvested? A great debate has been swirling in Northwest Indiana.

Only one egg had initially been reported at the end of May, but now monitors say Imani and Sea Rocket are incubating a full clutch of four eggs.

The endangered black-crowned night herons aren’t captive, they just happened to build their nests on the grounds of Lincoln Park Zoo. Why? Because they like having bodyguards.

All signs point to a cicada-induced vitamin deficiency as the cause of a mystery disease that affected some birds during a 2021 emergence and now again in 2024.

The egg is the product of a recent pair bond between native-born Imani, who hatched at Montrose Beach in 2021, and Searocket, one of the 5-week-old captive-reared piping plover chicks released at the beach last year.

Chicago’s own Imani has been joined by at least two other plovers, one believed to be a female. Let the mating games begin.

BirdCast, a project of Cornell Bird Lab and Colorado State University, has issued a high alert for Chicago, recommending lights out to reduce collision risks for birds.

Spring migration is still weeks away from reaching its peak in Chicago and already the tiny body bags are piling up, filled with birds killed in collisions with the city’s glass buildings.

Sharp-eyed observers have now confirmed hatchlings in three of the four bald eagle nests being monitored on Will County forest preserve property.

Wildlife officials are reporting that the season’s first Great Lakes piping plover, known as YibBee, has returned to his breeding grounds at Sleeping Bear Dunes. Will arrivals in Chicago be far behind?

In mid-April, the Chicago Department of Planning and Development is set to release an update to the city’s sustainable development policy. No section of the policy will make bird-friendly design mandatory.

All signs are pointing to another successful year of bald eagle mating in Will County.

Red-winged blackbirds, American robins, and sandhill cranes are among the species of birds Chicagoans have spotted in recent days on the leading edge of spring migration. But wait — according to the calendar, it’s still winter.

The Park District Board of Commissioners voted Wednesday to rename the plovers’ Montrose Beach meeting spot the Monty and Rose Wildlife Habitat.
