“The thing that bugs me about the often-stated idea that bald heads in birds are somehow a preferred adaptation for a scavenging lifestyle is that there isn’t a shred of evidence to support it. One, maybe two, taxa of large avian scavengers are bald, but the large majority of avians who scavenge for a living are not.”

Well, yeah. I did happen to think of crows and ravens, and how they don’t have bald heads.

(Oh. From what I hear it seems to be gaining scientific consensus that New World vultures, anyway, and storks are indeed related.)

Granted. “Evidence” isn’t simply “they scavenge and they have bald heads.” It is to me interesting though that the only birds – before this discovery, but then again maybe not! – that have bald heads do a lot of scavenging. It may be that corvids don’t have the need to plunge their heads into a carcass to get what they want from it. Vultures and condors are known to be very big eaters at carcasses; and as they tend to feed en masse, they can’t afford to be delicate. Also, the phrase “scavenge for a living” may need some review. Do corvids get *most* of their food scavenging? Or can they make do with foods that are also commonly eaten by perching birds? I frequently see them engaged in what appears to be just such activity. More often than I see them on dead animals.

I think, contrary to the bugged guy above, that regardless what one considers evidence backing the notion, there is much intuitive sense behind baldheadedness facilitating scavenging, and being selected for among birds that scavenge “for a living.”

Now another thing. This new bird doesn’t look like it has much neck to it. In other words, the feathers I see could get quite soily on a carcass.

But if we follow the evolutionary “rule” that adaptations selected for generally are so for a reason, well, scavenging is one that makes sense.

Look at this thread about bald headedness in modern birds and Archaeopteryx.

I had a hard time following it, but maybe you can gleen something.

Vultures appear to have their featherless heads because plunging a headful of feathers into a carcass could be messy, even fatally so. That’s not so typical a feeding mechanism for songbirds, though, unless of course for this one, it is. Wouldn’t THAT be interesting.

It’s always cool when someone finds a new animal.

Cool discovery, though.

Cool.

As a “follically challenged person” myself (VERY, to be honest), I can totally relate.
Great Discovery. May it sings for centuries to come.
