Options are, assuming it is natural, 1. just a strange inherited character (usually called a mutation) or 2. if the usual feather bases are black and it has lost a huge number of feathers from that area at the one time (which would be odd to be that extensive) and thus exposing the feather bases that are usually covered.

Hi Everyone,


I saw this buff-rumped thornbill at Mulligan's today but don't know why it has a band  of dark feathers across the front.


Photos are heavily cropped and very poor, but you can see the area I'm referring to.


Can anyone tell me what's going on with this bird?


Many thanks






Julie Clark
