Sorry ntheowl the link on that post was broken so we're reposting it. This study is one of the first steps to figuring out if they are indeed saying 'effing' There is call mentioned at the end of the blog post that is a contender for that interpretation.

Really unexpected lifer today in Wellfleet (Cape Cod): a Crested Caracara, which is supposed to be down the length of South America, maybe as north as Florida. Seen by many. @aba.org is this a MA first?
A slightly blurry bird: white neck, grayish/black body, black top of head, reddish orange face, pale thick curved bill. Standing in marsh grass.

Did you ask for a bird fact? No, but you're getting one whether you like it or not. 🪶
Photo by Frank D. Lospalluto of two Brown Creepers snuggled under an eave with their head tucked into the seam between 2 wood panels and their  back feathers fluffed up. Text on the graphic says "Unsolicited Bird Fact: During the fall and winter Brown Creepers like to cuddle. They are often observed snuggled together in small groups at sheltered roost sites, presumably to stay warm. Once young are fledged, parents roost separately. But young birds will sometimes roost together in larger groups. In Michigan, a group of about 6 young creepers were observed roosting in a tight circle with their beaks pointed towards the center.

Need a bird break today? Read about a long-running study of wild chickadee cognition in California's Sierra Nevada. www.sciencenews.org/article/wild...

Winter work shows it really pays to be a smart mountain chickadee
By studying chickadee cognition in the wild, researchers learned smarter birds stay smart in old age, produce more young and have better gut bacteria.

🪶 Buff-breasted Sandpipers are on the move from their Arctic breeding grounds back to South America. They've been spotted this month across the Great Plains and eastern US. Go Sandpipers! Go!
Photo of two Buff-breasted Sandpipers by Richard Gibbons, the male is displaying to the female. A comic speech bubble conversation reads as follows. Male: "Hey girl, get a load of this BUFF breast! Know why my muscles are so defined? It's because I'm an elite long distance migrant. I fly 15,000 miles between Nunavut & Uruguay 2x per year!" Female: "Big deal Chad, so do I! In fact you were drafting behind me all last night and wouldn't stop yapping to your buddies about how much easier it was to fly in my wake." Male: "That just shows I'm intelligent." Female: "Whatever Chad."

Contemplative Blue Jay #birds
Gorgeous bird with blue crest, black and white face and silver breast. Its crest is flat, indicating that it is relaxed. The bird is facing forward with its head turned to its left. The background is almost black with a small cluster of wet leaves in the upper right corner of the frame. It’s a peaceful scene and the bird appears deep in thought.

Hope you get some time outside and find some peace this weekend. 🪶
Photo of a Great Blue Heron and Wood Duck drake in a pond surrounded by lily pads by user readerwalker on Flickr. Text on graphic is the poem The Peace of Wild Things by Wendell Berry (1934-2026) "When despair for the world grows in me
and I wake in the night at the least sound
in fear of what my life and my children’s lives may be,
I go and lie down where the wood drake
rests in his beauty on the water, and the great heron feeds.
I come into the peace of wild things
who do not tax their lives with forethought
of grief. I come into the presence of still water.
And I feel above me the day-blind stars
waiting with their light. For a time
I rest in the grace of the world, and am free."

Do any Floridian ornithologists follow me? I'm looking for three birds that eat caterpillars and might get fooled by a giant swallowtail's poop mimicry. I've narrowed them down to Painted Bunting, Northern Mockingbird, and Red-winged Blackbird. Are those good choices?

🪶 Unsolicited Bird Fact #4: The Island Scrub-Jay only occurs on Santa Cruz Is. off the CA coast. Island Scrub-Jays & Yellow-billed Magpies are the only 2 bird species that only occur in California. They are super-sized: 15% larger, 40% heavier, with 20% longer bills than their mainland relatives.

Did you ask for a bird fact? No, but you're getting a bunch of them in this thread whether you like it or not. 🪶 1. Florida Scrub-Jays only occur in Florida & they are cooperative breeders! Young birds stay with their parents for an extra year & help raise the next batch of their youngest siblings.

A Snowy Egret (Egretta thula) in breeding plumage is the #BirdoftheDay for the theme #ItsAllWhite. Easy to see why these stunning birds were hunted for their beautiful feathers years ago until they were protected in the early 20th century. #birds #Florida
A dramatically side-and back-lit Snowy Egret in breeding plumage is perched atop a rough gray snag facing forward and looking slightly downward, showing off an impressive crown of delicate white feathers over their head, and looking fierce with yellow eyes, red lores, and black beak. The background is completely black. Easy to see why they were hunted for their feathers until they were protected in the early twentieth century.
