Drill

This is the younger male. Monkey House. May 2008

Nice shot,great clarity of the face and eyes.

He's gone somewhere else now- Sweden?- together with the original handraised female.

I wonder if either(or both) of the two females from the US have become pregnant yet from the other male.

The drill pictured is the hand raised female, and she is indeed in Sweden now.

I think my original caption is correct - I am sure this is the younger male photographed 2 years ago.

But Ilembo was born in 2000. Either you are mistaken or I'm misinformed on what drills have been at Edinburgh. As far as I know there have only been two males there, Ilembo and N'Boa. A male drill doesn't look like that at 8 years of age.

A dominant male will certainly be getting 'fatted' by this age. Ilembo was, as shown in my rather poor photo from 2007.

But a less dominant male of the same age will not mature in this way and so will not look very different from a female. As an extreme example, Gorbi's eldest son at Port Lympne, Kassalo, who has been castrated, looks only slightly larger and rather slimmer than an adult female, but he is 9 years old.
I am sure that this individual was significantly larger than the female at Edinburgh, who appeared to me to be unusually small.

Now I'm a bit confused as to what you are saying. Are you saying that the drill in the picture in your post above is Ilembo in 2007? Them clearly you agree that the original picture we are discussing isn't the same animal right?

However, the last picture you attached isn't Ilmebo, but N'Boa.

You took the picture so you probably know what you are talking about. I won't post anymore on this topic since we clearly disagree.

The thing is that I know Kapi quite well, and to me the drill in the original picture look exactly like her.

I'm sorry, I have muddled the names. The second picture is the dominant male, who is still at the zoo. I am certain that I didn't shoot the female - as I thought she was such a poor specimen, so I am convinced it is the subordinate male. We will have to agree to differ.
Funnily enough I spent some time two days ago shooting the subordinate animals at Port Lympne, as Gorbi was not in a co-operative mood and I certainly found it difficult to distinguish them facially - perhaps I haven't got a good eye for this species: I just don't see them often enough.

The females are tiny-looking compared to the adult males, though an adult female, as in many primate species, has a squarish 'stout' look about her that the younger ones don't have.

The castrated male at PL has no doubt had his growth affected too. Last time I saw him he was indistinguishable from the females except by his sex. He has probably grown a bit since then though.

Did you notice how many Drills Port Lympne have now and if any infants have been born this year?
