[ a ] Making use of the natural relationship between raptors and their prey, falconry is now used to control pest birds and animals in urban areas, landfills, commercial ...
A few days before Halloween, data collectors at the Jekyll Island Banding Station (JIBS) observe a steady, yet predictable, decline of birds in nets, signaling the end of migration.
Birds (and their more reptilian cousins, the Crocodilia) are the modern-day legacy of dinosaur’s 165-million-year-long stint on Earth. While our avian friends’ Mesozoic origin story isn’t up ...
