    Small, but fierce, our latest Bird of the Week lives in forests across North America. It's nocturnal & tough to spot—but once in a while you might find one in a giant Christmas tree headed for New York City. Have you seen a Northern Saw-whet Owl lately? bit.ly/3pQEm2c

    MIGRATION ALERT: More than 600 MILLION birds predicted for tonight! Given the tragic mass window collisions in Chicago (see our previous post), it's an important time to dim nonessential outdoor lights at night & make your windows safer for birds: birdcast.info/science-to-act…

    Our Bird of the Week lives in the high Arctic. When it makes it down to the contiguous US, it's as if a breath of the northern winter accompanied it—and looks like it's been kissed by the hoarfrost from which it gets its name. Seen Hoary Redpoll lately? bit.ly/35mCANG

    How about that owl in the Rockefeller Christmas tree? It's a Northern Saw-whet Owl, possibly the cutest owl on the planet. Read up on these fierce little predators in our story from last year:

    Our Bird of the Week brings a dose of cuteness in the winter when it arrives in the Lower 48. This winter it's predicted to travel further south than usual, so stock up your feeders with millet and thistle seeds. Have you seen a Common Redpoll lately? bit.ly/32IkTam

    On a small island off New Guinea, a camera trap has captured the first images *ever* taken of the Black-naped Pheasant-Pigeon, a bird that has not been seen by scientists in 140 years.

    Migration Alert! Tonight thru Saturday, expect over 300 MILLION birds in the air each night. Bright lights can disorient them—make a difference by turning off non-essential lights and making windows safer. #LightsOutForBirds #LightsOutTexas #DarkSkies birdcast.info/science-to-act…

    Moving silently across northern landscapes, our latest Bird of the Week haunts dense evergreen forests and meadows and you have to wonder whether its powerful presence gave rise to stories of haunted forests. Seen a Great Gray Owl lately? Happy Halloween! bit.ly/3mAGsRu
