It might be Little Gull...if I'm ever to see one!

L is for Laridae (#Skimmers, #Noddies, #Terns & #Gulls). Of the 105 species found worldwide, 59 have been recorded in the U.S. and Canada. From the tiny Least Tern to the massive Great Black-backed Gull, this group inhabits almost every corner of the planet. What’s your favorite?

Waterfowl (collective) are my spark bird. I'm not sure I could choose one, three, or ten. Oof, not sure if another group hits so hard for me.

A is for Anatidae (Ducks, Geese, and Swans). Roughly 172 waterfowl species grace the globe, with 71 recorded in Canada and the U.S., including Hawaii. From toned-down teal to wildly ornate Wood Ducks, this family stuns. Which waterfowl wows you the most? 📸: Chris Roberts

Newfoundland is a rugged wilderness at North America’s eastern edge. Read Audubon’s senior coordinator of avian biology @ChadWitko’s experience aboard the first Indigenous-led cruise there to a newly proposed offshore national marine conservation area: bit.ly/44OVtH0

A friend of a friend of a friend found this dead bird along the bank of the Merrimack River in MA. Some friends say it looks like a penguin. ChatGPT says it’s a Canada Goose. What say you?!?

Last night, Sibley spoke at a local library. He signed a few books, including this bird-finding guide to NJ. This was my first exposure to his art, long before his field guides. He stared at it as if seeing a long-lost relative. "Wow! I don't think I've ever signed one of these!"
