Can you tell me about poisonous birds? I trust you way more than Google, especially with its new unreliable AI...

POISONOUS BIRBS:

Hey there, so I know about Pitohuis (there are 8 species), Blue-capped Ifrit, Regent Whistler, Rufous-naped Bellbird, Arafura Shrikethrush, Rufous Shrikethrush sequester Batrachotoxins in their feathers and skin (as well as in some internal organs), obtained from their diet (most likely beetles in the genus Choresine). All are endemic to New Guinea.

Red Warblers, Spur-winged Geese, European Common Quail, Bronzewing Pigeons, and Ruffed Grouse also sequester toxins form various insects, seeds, and berries (depending on the species), and can be toxic.

Hoopoes have bacteria in their uropygial glands that produce toxins.
