Anting

A strange behavior engaged in by birds. From wikipedia:

Anting is a maintenance behavior during which birds rub insects, usually ants, on their feathers and skin. The bird may pick up the insects in its bill and rub them on the body (active anting), or the bird may lie in an area of high density of the insects and perform dust bathing-like movements (passive anting).

Female mate avoidance behaviors in the European common frog

We posted recently about "misdirected amplexus," which is the phenomenon of male frogs attempting to mate with inappropriate objects (different species, fish, inanimate objects, etc.).

Turns out that the weird frog sex behaviors don't end there. Male frogs, in their excitement, will occasionally form "mating balls" — "several male frogs cling to a single female – often killing her in the process."

Some German researchers have now found that female frogs, in turn, have developed defense strategies to protect themselves from over-excited males. They rotate to try to escape the male's grasp; they emit "release calls"; and if those strategies fail to work, they play dead:

to protect themselves against swarms of sexually aroused male frogs, the female frogs stiffly extend their arms and legs away from the body, keeping incredibly still until the male releases them from its grasp.

Ultrasonic Postejaculatory Song of the Male Rat

We posted recently about some odd sexual behavior demonstrated by frogs (their frequent attempts to mate with inappropriate objects). Male rats also display an odd behavior. When they need to rest from mating, they sing an ultrasonic "leave me alone" song.

The Chimpomat

In one of our recent posts, there was a reference to the Chimpomat, a token-operated vending machine for chimpanzees created at the Yerkes Laboratories in the 1930s. Here's more info about it.

"Subject Kambi is shown about to drop a token into the slot of the chimpomat to 'purchase' food."



Info from The Ape People (1971) by Geoffrey H. Bourne:

The Yerkes Laboratories eventually developed a device known as a Chimpomat. This Chimpomat would receive either metal or plastic disks and would dispense some form of food reward in return for the insertion of a disk. Animals were eventually taught to pull the box of weights up to the cage in return for plastic or metal disks which they could then take and put in the Chimpomat to get their reward.

By the process of lengthening the time between which they could earn the reward and when they could actually receive it by using the Chimpomat (by making the Chimpomat available only certain times of the day), the animals could be trained to collect plastic disks, in other words, to work for money. They would store up this money until the time came for them to spend it. Eventually they were trained to earn the money one day and spend it in the Chimpomat the following day.

On these occasions the animals used to walk around clutching their earnings to their breasts, sleeping on them at night so they would not be stolen, and getting very hysterical if any other animal came near their earnings or tried to take any of them away—a very human side of their actuvity and the dawn of ownership of private property and capitalism, a thought that has intriguing implications.

Misdirected amplexus

"Misdirected amplexus" is the scientific term for the curious phenomenon of male frogs attempting to mate with inappropriate objects. Details from the New Scientist

Mating frogs may have been occasionally getting it wrong for hundreds of millions of years. We know that males today will sometimes select an inappropriate partner during the breeding season – a frog from a different species, a turtle, a fish or even an inanimate object. Now there is evidence that these mistaken attachments could be an ancient feature of frog reproduction, arising early in the amphibians’ evolution.

Frog mating is often hard to miss. In most species it involves a process called amplexus, in which males grip onto a female tightly for hours or days at a time until the eggs are fertilised. But there are plenty of records of male frogs grappling an unpromising target such as a frog from a different species or a dead individual. One explanation is that such mistakes are more likely to happen in species that breed in large numbers with a low ratio of females to males, and where multiple species occupy the same breeding pond.

I briefly discussed the subject of misdirected mating in the animal kingdom in my book Elephants on Acid. Here's the relevant text:

Konrad Lorenz once observed a Shell Parakeet who grew amorous with a small celluloid ball. And many other animals exhibit mating behavior toward what researchers refer to as "biologically inappropriate objects." Bulls will treat almost any restrained animal as a receptive cow. Their general rule in life seems to be, "if it doesn't move away and can be mounted, mount it!"

During the early 1950s, researchers at Walter Reed Army Medical Center surgically damaged the amygdala (a region of the brain) in a number of male cats. These cats became "hypersexual," attempting to mate with a dog, a female rhesus monkey, and an old hen. Four of these hypersexual cats, placed together, promptly mounted one another.

Artwork Khrushchev Probably Would Not Have Liked 52

I must confess to a slight divergence with this entry. All previous ones have featured artwork from within Khrushchev's lifetime, stuff he could have theoretically seen and reacted to. (He died in 1971.) But this one postdates the man.

That is all.
