Female gorillas use sex as a tactic to thwart their rivals, new research suggests. Pregnant apes court their silverback male to stop other females conceiving.

“It seems to us that mating is another tactic that females use to compete with each other – in this case to gain favour with another male,” says Diane Doran-Sheehy, a primatologist at Stony Brook University in New York.

Two baboons decide the hood of a car is the perfect place to attempt reproduction. The people in the car find this pretty amusing.

The title pretty much explains this video. You didn’t think we’d have multiple days of baboons on Monkeyology without one or two of these did you?

Two monkeys having sex on the hood of your car. Now that’s a hood ornament.

As the classy monkeyologist, I wouldn’t pass up this video of a monkey humping what looks like a stuffed animal.

And a bonus video today:

“What’s amazing is that if a male shares with a particular female, he doubles the number of times he copulates with her, which is likely to increase the probability of fertilizing that female.”

Check out the story at BBC News.

However, on top of that heavy social schedule, they still found time to spend about 15 per cent of their hours having sex (with friends, acquaintances and in groups comprising both sexes, often in a jolly tangle of fun and frolics).

Furthermore, they only spend about 0.0002 per cent of their time fighting among themselves. So my question is this: If this is how bonobos spend their time, why do we humans think we are the superior species?

It’s a great article.

Yesterday we had some tame video of Mandrills. Now here’s one of them doing what everyone who visits the zoo enjoys seeing the most. Just listen to the laughing in this one.

Here’s yet another video of chimps having sex. This video has some amusing commentary from the guys watching it happen.

Don’t ask me why, but here’s a video of Bonobo’s mating. These guys have more sex than any animal on earth. It’s like a handshake to them.
