Macaulay Library at the Cornell Lab

Watching birds at your feeder provides hours of entertainment. And every once in a while, a Cooper’s Hawk or a Sharp-shinned Hawk might fly in and stir things up. New research using FeederWatch data set out to learn more about these similar bird-eating raptors. Sharp-Shinned and Cooper's Hawks are choosing different foods based on size, which may allow them to coexist. Read more about the study at:

What’s For Dinner? Sharp-shinned and Cooper’s Hawks Pick Different Foods By Kathi Borgmann Watching chickadees and finches jostle at your feeder provides countless hours of entertainment. And every once in a while, a Cooper’s Hawk or a Sharp-shinned Hawk might fly in and stir things up. These two bird-eating raptors co-occur throughout much of North America, but given ...

Have you been recording bird sounds recently? Just as you might crop your photo before you add it to your eBird checklist, you'll also want to trim your recording to get rid of any handling noise at the beginning or end of your recording.

Recordings in the Macaulay Library power birding tools like Merlin Bird ID and Merlin's new Sound ID feature, plus science, conservation, and the arts. Add your recordings to your eBird checklist to be part of science and the future of birding tools.

Alarm Calls Everyone Knows: an Innate Response to Unfamiliar Calls Our environment is filled with sounds from bird songs to sirens, from music to barking dogs. As humans we’ve mostly learned what each sound means and we respond appropriately—we may seek shelter w

No matter where you are in your sound recording journey, the Macaulay Library at the Cornell Lab of Ornithology wants to support you with key information on How to Record Bird Sounds. Learn more about our new, online course!

How to Record Bird Sounds | Bird Academy • The Cornell Lab A friendly guide to finding birds, fieldcraft, gear, sound editing, and the joy of recording bird sounds.

Merlin’s new Sound ID feature is magical, but it’s important to compare each sound identification suggestion in Merlin against the example recordings and range maps to make sure the ID is a good fit. If possible, try to see the bird making the sound!

Audio recordings inform science but also inspire art and a new way to connect with our world. Artist Millicent Young created a multi-media installation about extinction and loss titled "Remains" that features the song of the now extinct Kauai O'o from the Macaulay Library.

New research finds that Ruby-crowned Kinglets with small but mighty voices have different song dialects suggesting that song is a learned behavior. Mapping dialects can help better understand migratory connectivity 🌎. This research was made possible thanks to many Macaulay Library contributors.

Song dialects of the Ruby-crowned Kinglet – Association of Field Ornithologists Song dialects of the Ruby-crowned Kinglet June 20, 2022June 20, 2022 Ed Pandolfino Many bird species, like humans, have distinct regional dialects. A New Yorker may refer to a midday meal as “lunch”, but in the south that meal is “dinner”. Likewise, the song of a Common Yellowthroat in the e...
