Bright lights in the big cities: migratory birds’ exposure to artificial light

New research from the BirdCast team highlights risks of exposure to artificial light at night for migrating birds. We ranked metropolitan areas where birds are at the greatest risk of becoming attracted to and disoriented by lights.

First arrivals: “Spring” 2019 BirdCast

With the vernal equinox approaching, Team BirdCast welcomes back our forecast and live migration maps for the spring 2019 season!

Tracking Hurricane Michael

Hurricane Michael strengthened rapidly into a major hurricane on Tuesday, and as with previous storms on which BirdCast reported, it may have dramatic impacts on local and transient bird communities and their habitats when it comes ashore and passes through the Southeastern US. Live sightings will appear on the current observations map as they are entered into eBird, but as always, for those in the path of this storm, safety first!

Interactive Map: Tracking Hurricane Rosa

Real-time sightings from your eBird checklists will appear in this post's map, providing a unique opportunity to help us understand how these storms transport birds and how birds respond to extreme disturbances in their annual cycles.

Interactive Map: Tracking the dangerous Hurricane Florence

Hurricanes and their impacts, in particular in depositing seabirds far afield from their normal haunts, represent unique opportunities to understand how animals behave in and respond to serious disturbances. Hurricane Florence is no exception.
