Did you know that both male & female Mangrove Yellow Warblers sing and duet? This is one of the many differences supporting its split from the Northern Yellow Warbler. If you’re curious to learn more, read the BOW article about the Mangrove Yellow Warbler here!

Nothing exemplifies the spirit of birding like lying down in the wet grass with a complete stranger to get pictures of a sparrow while people walk past on the sidewalk five feet away

Since Trump fired most of the National Park Service, the bears have to pick up the slack.

Welp this is horrifying. These researchers quantified the "stratigraphy" of plastic waste used in Common Coot nests. Using expiration dates, they found one nest that contained 635 (!!!) pieces of trash, including plastic dating back to 1991.

Oh Pacific coast, how I missed you so
A vividly patterned male Harlequin Duck chases a brown female on the water, splashing water in their wake. Several dozen Steller Sea Lions loaf amongst the rocks of a small island, with many more in the water just off shore, seen as snouts poking out of the water. A non-breeding plumage Black-bellied Plover stands on a rocky outcrop covered in rockweed. A Black Oystercatcher stands at the water's edge, face-to-face with a pale, young Short-billed Gull in the shallow water.

I feel like we remove power from amazon by NOT TALKING ABOUT AMAZON.
Mention the library. Mention the indie bookseller. Mention the direct stores.
LINK to the publisher or the direct store or the author website.

You don’t even have to bring up Amazon or link to them.

Banding birds has really given me a wonderful new level of understanding, such as being able to differentiate age classes of birds in the field by paying attention to small plumage details. 1/
A presumed immature Tufted Titmouse perched on a bare branch. What is visible of its primary coverts shows that the feathers are darker than the grey greater coverts covering them. The last primary appears brownish and juts out noticeably from the rest of the wing. An adult Tufted Titmouse perched on a thorny, bare branch. Unlike the bird in the previous photo, the primary coverts on this bird show wide grey edging, similar in colour to the greater coverts. The last primary barely peeks out from underneath the other primaries.

Via @maketheroadny.bsky.social: If ICE shows up, know your rights.

“ICE does not have the right to enter your home without a valid warrant signed by a judge.”

maketheroadny.org/we-protect-us/
IF ICE SHOWS UP, KNOW YOUR RIGHTS! If immigration (ICE) comes to your door or stops you in the streets, you have rights! 1. DO NOT OPEN THE DOOR ICE does not have the right to enter your home without a valid warrant signed by a judge. POLICE ICE ? ICE will not always identify themselves as ICE. If there is a knock at your door and they say "Police" it could very well be ICE. ICE will often say they are police to gain access to homes. If at any point they try to enter, or do enter, continue to say "I DO NOT CONSENT" If they insist they have a warrant ask them to slip it under the door. 2. REMAIN CALM Don't run and most importantly do not lie about your name, age, immigration status, etc. Anything you say or do can be used against you. If ICE questions you, under the 5th Amendment, you have the right to remain silent and to not incriminate yourself. If you are detained, ask for an immigration attorney immediately. Although immigration does not provide attorneys, once you ask for an attorney they should no longer question you. 3. DO NOT SIGN ANYTHING Ask to have documents translated. If you do not speak English ask for an interpreter. Have an attorney look over any documents that ICE gives you. 5. MAKE A FAMILY PLAN If you have children, identify a caretaker. 4. RECORD If you witness someone being detained by ICE, you have the right to record as long as you do not interfere with the arrest. Pictures, videos, and any information you can gather, can help verify an immigration raid and also help someone's immigration case. Make sure your family is prepared if ICE arrives at your home. Have all your personal documents and finances secure. Make sure you have at least one number memorized in case of an emergency. MAKE THE ROAD NEW YORK

#ArtAdventCalendar day 15 meets #SciArt Sunday! (That's every day for me). This illustration from 2023 depicts a potential difference in UV spectrum reflection on eye combs in female/immature vs adult male Red Grouse/Willow Ptarmigan w/ males showing less reflection. See reply 🎨🪶🐡🧪 #birdart
A diagram of four Red Grouse portraits. Top row females, bottom row males. On the left, birds in daylight. On right, birds in UV light. The comb above the female's eye glows brightly under UV, while the glow is much reduced in the male.

If a Tree Swallow wore pants, it'd definitely wear them like this
A Blue-and-white Swallow viewed from below. The throat and belly are white, contrasting with black tail feathers and undertail coverts, giving the appearance that the bird is wearing pants.

Getting cold in Ontario for these wayward Cave Swallows!
A small swallow faces forward, sitting on a light fixture protruding from a stucco ceiling. It's blue on its left wing and on top of its head, while its forehead, throat and cheek are a light, dull orange. A Cave Swallow sits on on a sandy beach littered with fallen leaves. Facing right, its orange rump is visible, contrasting with its steel blue back and crown. Its forehead and cheek are also orange, and it has a pale collar around its nape.
