One of two male Black Bushbirds calling and rocking up and down, displaying their white intrascapular patch. I can't find any reference to this behavior in searches online, including Birds of the World - except for a xeno-canto recording by Andrew Spencer (https://xeno-canto.org/97469), in the notes of which he describes the same behavior in a male displaying to a female. That recording is also the only audio recording I can find of these particular calls. Possibly the first video documentation? I can't find any photos in the Macaulay library showing the white intrascapular patch of the male at all. I would have recorded longer, but was running very low on memory. Apologies for the shutter sounds, which even mirrorless Canons apparently still make... :-P

Amazing close views of two males aggressively displaying. The birds were perched about 3 feet apart from one another. As they vocalized, they would dip forward on the perch and flare a patch of white feathers on their backs. Exceptional lifer experience!
