Black-Crowned Night Herons

A group of black-crowned night herons has long chosen DC’s National Zoo as a breeding grounds (they’ve been visiting for about one hundred years!). They set up shop in tall trees around the birdhouse, stay for a while, and then take off. This year, researchers at the zoo tagged them with radio transmitters to see where they go each year once they leave the zoo. The Post had a short article about it today. Enjoy!
