Sub-adult koel (Eudynamys scolopaceous) markings

posted in: birds, Eudynamys scolopaceous, koel | 0

It was interesting to observe the different feather markings of the male sub-adult Asian Koel bird (Eudynamys scolopaceus). I have attached 5 photos to present various views of the feathers. These photos were taken over various times and therefore may not be the same bird.

The first 3 photos are flight shots which showed that the white-tipped feather markings appeared on 2 sets of feathers; the greater primary coverts and the greater secondary coverts. These feathers were also dark brown, contrasting with the others which were glossy dark green. Photo 4 shows clearly the contrasting colours when the bird is perched on a branch. These brown feathers will eventually turn to the glossy dark green feathers as the bird matures.

In photo 5, under direct light, the glossy dark green feathers display their shiny surfaces contrasting greatly with the duller brown feathers. The white markings on the brown feathers were still visible, including the upper-tail covert feather and the rump which were not seen in the earlier photos.
