Physiologically it is possible for vultures to hunt, although the prey would have to be cumbersome and incapable of getting away easily. The toes and talons of most vultures are not specialised for hunting and making a kill.

However, these birds are still formidable and will kill if they have to. The 2 species expected to be less successful hunters are, the cape and white-backed vultures as they in particular, have short, stubby toes, ill suited to catching prey.

Thanks Imberbe. IT! :thumbs_up:

:thumbs_up: Thanks, interesting! :thumbs_up:

The Palm nut vulture is an interesting bird. Not least of all is its connection with another, much more common and iconic raptor. Name this raptor and what connects the two species? Hint, this other raptor is not a vulture.

The mating game of the Red-billed Buffalo Weaver.

The mating system of this bird is extremely unusual and is only rivalled by one other species in the world. Describe this.

(Warning, the answer will contain words used by gynecologist and urologists)

The buffalo weaver is unique in that copulation can last as long as two minutes where as with other birds it usually take only seconds.

The male birds have a permanently erect phalloid organ which enlarges even further during the breeding season. This phalloid organ is thought to facilitate the mating process although it is not a penis.

No further answers, so here it is.

These birds build colonies of huge, compound nests in the top of windmills and on broad, tall trees. With so many birds in such close proximity, it is not surprising that the offspring of each individual female are often fathered by more than one male. Male buffalo weavers also possess a long, rigid non-retractable penis-like structure or 'phalloid organ', positioned just in front of the cloaca, which is unique amongst birds. It contains no duct or or openings, is not inserted into the female's cloaca during copulation, and so does not transfer sperm.

Indeed sperm is transferred the same way as other passerine birds.

(I guess a bit too scientific)

Whoever wants it, take IT.

:clap: Rooies. Interesting information. :thumbs_up: It is as I have it as well. The organ is not for actual mating.

Joao ... for having is partially correct .. why don't you take it.
