Nationwide maps of bird species can help protect biodiversity

April 15, 2022

The high-resolution maps can help conservation managers focus their efforts where they are most likely to help birds — in individual counties or forests, rather than across whole states or regions.

Songbirds sing — like humans flock — for opioid reward

October 1, 2020

New research found that when songbirds sing during non-mating seasons, it’s because singing releases an opioid naturally produced in their brain —that’s right, a compound with the same biological makeup of the highly addictive painkillers.
