Piping plovers are winging their way north and one has already been spotted at Rainbow Beach. Word is that Monty could be en route to Chicago.

Decorated eggs are a centuries-old Easter tradition, but nature’s been at it eons longer — no dyes required. Take a look inside the Field Museum’s egg collection. 

The deaths occurred at the Baker’ s Lake forest preserve, the Forest Preserves of Cook County said in a statement on Thursday.

The teams behind each Chicago casino proposal were asked how they plan to incorporate bird-friendly elements into their architecture. Some tipped their hand, others kept their cards close to their vest. 

If a casino is coming to the riverfront, publicly accessible open green space should be a priority, as well as considerations for wildlife habitat, environmental advocates say. And the buildings themselves should be held to the highest standards of sustainability and climate resiliency.

A new study led by the Field Museum shows that a number of bird species are laying their eggs nearly a month earlier than 100 years ago, likely due to climate change.

The strain of highly pathogenic avian influenza circulating in the U.S., the first since 2016, doesn’t appear to pose a threat to humans, but is highly contagious among birds and often fatal.

Robyn Detterline’s March Chicago Collision Bird Migration Madness tournament may be a product of her own imagination, but the stakes are very real for birds when it comes to navigating their way safely through Chicago.

Cook County’s forest preserves are much loved for their picnic groves and trails. Not as well known: The forest preserve district’s role as a research hub and early warning system of sorts against zoonotic diseases.

Carvana’s 14-story glass tower will be a blight on Skokie, said residents, whose frustration boiled over at Tuesday night's meeting of the village’s Board of Trustees, where the project received final approval.  

The snowy owl and the long-eared owl elicit the sort of reaction usually reserved for rock stars, including the intrusion of cameras into their personal space. Recent incidents involving aggressive photographers have reignited a debate over whether owls' locations should be shared publicly.

The snowy owl is being treated at Willowbrook Wildlife Center, where a bald eagle is recuperating from the same issue. Anticoagulants in rodenticides can be deadly to the birds of prey that eat poisoned rats, mice and other rodents.

The radio antenna, positioned at Big Marsh Park on the Southeast Side, helps fill a Chicago-sized gap in a growing network of receivers that's tracking the movement of migratory birds and other animals.   

In response to concerns about putting a see-through glass tower in the path of migrating birds, Carvana revised its plan to incorporate bird-friendly components. Critics called the proposed mitigations “woefully inadequate.” 

A 140-foot-tall transparent structure that’s brightly illuminated 24/7, located across the street from Harms Woods nature preserve, along a key migratory greenway, is a triple threat to birds, environmentalists say.

One of the country’s longest-running community science projects is about to get underway. We’ve got all the details on Audubon Society’s 122nd annual Christmas Bird Count, including how to join the effort.
