Did you know? Fairywrens (Malurus cyaneus) and many other bird species share a common alarm call to alert neighbors of approaching cuckoos. Could this be how shared language evolves? pubmed.ncbi.nlm.nih.gov/41044184/ 📸 Caroline Jones, via Wikimedia Commons (CC0)

Did you know? The Secretary bird (Sagittarius serpentarius) is named after the long feathers on its head, resembling quill pens tucked behind a secretary’s ear. It hunts snakes by stomping on them with its powerful feet. 📸 Hobbyfotowiki, via Wikimedia Commons (CC0)

Did you know? The Kauaʻi ʻōʻō (Moho braccatus), once native to Hawaii, is most likely extinct. This bird was famous for its haunting love song. Listen to the last singing male recorded in 1987: tinyurl.com/2w4kuz2z. 📸 Robert Shallenberger, via Wikimedia Commons (CC0)

Did you know? Malleefowl (Leipoa ocellata) incubate their eggs in large mounds of rotting leaves. The male adjusts the mound daily to keep the temperature perfect. The chicks hatch fully independent and never meet their parents. 📸 melissadoherty, via Wikimedia Commons (CC0)

DID YOU KNOW? Hoatzin chicks (Opisthocomus hoazin) have claws on their wings to climb branches if predators attack. If that fails, they drop into water below the nest, swim away, then climb back up later—an amazing survival trick! 📸Philipp Hoenle, via Wikimedia Commons (CC0) #Birds #FeatheredFriday
A Hoatzin perched on a bare tree branch. The bird has a spiky reddish-brown crest, blue facial skin, red eyes, and brown wings with cream and chestnut highlights. Soft, blurred background of blue and green hues.

DID YOU KNOW?! Flamingos (Phoenicopteridae) produce so-called crop milk to feed their chicks. Unlike mammals, both parents produce it. Can you guess the color of flamingo milk? It’s bright red! 📸 Carlota Vidal, via Wikimedia Commons (CC0)
