In some cases, up to 70 percent of the eggs found in some nests were fertilized by a male other than the primary occupant, protector, and supplier of the nest. According to Forbes , the animals were split into a problem-solving group of 18 males and 9 females and a control group of 16 males and 8 females. So beauty still matters. In trials, the team used food to sweeten the pot. During mating seasons, the cloacal openings of both male and female birds swell, protruding slightly outside their bodies. But some research indicates it's really the females that are most eager to find alternative sources of DNA. When the hanky panky is over, preen a little. These researchers, from the University of East Anglia, captured more than 97 percent of the warblers on the tiny island of Cousin in the Seychelles. The birds would even change their selection if the previously overlooked mate learned a new trick. Follow Elizabeth Palermo on Twitter techEpalermo. Now, a new study published in the journal Science suggests that female budgerigars, a species of small Australian parrots better known as budgies, employ this selective brand of logic when playing the mating game. But here's the cold side: But purple martins and swallows in Europe have figured out how to beat the cuckoo. All chicks were tested to identify the father. Next, Carne reports for Cosmos, the scientists brought the newly-skilled budgie back out to the mating arena. That made them stronger than the competition during those crucial early days, and that could give them an advantage for the rest of their lives, the researchers concluded. But that sweet song began to sour a few years ago when scientists, armed with the powerful tools of modern genetics, began capturing birds around the world, and borrowing eggs from active nests, and even following the lives of the hatched chicks to see what was really going on in the avian bedroom. Following this observational period, the female budgies again chose between the two potential mates. After 15 minutes, the researchers collected the body and later found it was a male see video, below. While the new couple continued courting, the researchers trained the rejected budgie to open two puzzle toys—a petri dish and a three-step box—filled with food. When birds are feeling frisky, they rub their swollen cloacas together. Then they monitored the fate of birds that hatched between and for 10 years and found that 40 percent of the offspring were fertilized by males other than the female's mate. Journal reference: The male's sperm, which has been stored in his cloaca, is deposited into the female's cloaca, where it travels up the chamber and eventually fertilizes an egg. It is only when the body is collected that the sex of the dead bird can be confirmed, says Kees Moeliker of the Natural History Museum Rotterdam, the Netherlands.

The Yamashina researchers think the event they witnessed occurred because the dead bird happened to end up in a pose resembling the female mating position. The cloaca is an internal chamber that ends in an opening, and through this opening, a bird's sex organs — testes or ovaries — discharge sperm or eggs. This provides two advantages: Instead, both male and female birds have what's known as a cloaca. The female bird has a unique ability to influence which eggs hatch first. So beauty still matters. In one ambitious study, British scientists found that female Seychelles warblers prefer having their eggs fertilized by a male other than their social partner. These birds do not appear to be all that colorful to human eyes, but the feathers on the tops of their heads reflect ultra-violet light, which birds can see, giving them more color and the necessary sex appeal. As for necrophilia, at least 30 cases have been reported in birds of all kinds. As Nick Carne writes for Cosmos , a team of Chinese and Dutch researchers found that female budgies preferred brains over beauty and brawn. But that sweet song began to sour a few years ago when scientists, armed with the powerful tools of modern genetics, began capturing birds around the world, and borrowing eggs from active nests, and even following the lives of the hatched chicks to see what was really going on in the avian bedroom. If the cuckoo's egg hatches first, the chick will nudge any other eggs over the side of the nest, thus becoming an only child. But in Darwinian terms, the recipe for reproduction is far more clinical, with animals seeking mates based on the potential evolutionary advantage—often superior cognition skills—offered by a match.

They build their nests near humans, and cuckoos don't care much for our species, thus leaving the nests alone. Usually, the male perches on top of the female, who moves her tail feathers to the side to expose her cloaca. Ornithological Science, DOI: But their paper is too similar to his to merit an Ignobel, according to Moeliker, who is now on the Ig Nobel committee. When birds are feeling frisky, they rub their swollen cloacas together. And despite rumors to the contrary, it isn't possible for birds to have sex while in flight.

This same opening also serves a less-sexy purpose: Biologist Bridget Stutchbury, who has authored two books on the subject, said the female is the most opportunistic, and she doesn't have to look far to find a male who's willing to fill her needs, at least as far as the birds in her Canadian backyard are concerned. In some cases, up to 70 percent of the eggs found in some nests were fertilized by a male other than the primary occupant, protector, and supplier of the nest.

For humans to understand bird sex, they must first throw out all thoughts of mammalian sex organs. That made them stronger than the competition during those crucial early days, and that could give them an advantage for the rest of their lives, the researchers concluded. In order to watch interactions unfold, the scientists placed three birds into a divided enclosure in which the female could only engage with one male at a time, reports Agence France-Presse. The female bird has a unique ability to influence which eggs hatch first. This provides two advantages: But in Darwinian terms, the recipe for reproduction is far more clinical, with animals seeking mates based on the potential evolutionary advantage—often superior cognition skills—offered by a match. She can store sperm for days in her reproductive tracts, releasing some from the outsider to fertilize some of her eggs, giving them a few hours head start, and a few hours later release some from her mate for the remaining eggs, ensuring that he will hang around to help raise the young. Scientists with the Konrad Lorenz Institute of Ethology in Great Britain captured female blue tits just after their eggs hatched.

If the cuckoo's egg hatches first, the chick will nudge any other eggs over the side of the nest, thus becoming an only child. Unlike mammals, most male birds don't have penises. This same opening also serves a less-sexy purpose: Arching back, the male rubs his cloaca against hers. Then they monitored the fate of birds that hatched between and for 10 years and found that 40 percent of the offspring were fertilized by males other than the female's mate. Instead, both male and female birds have what's known as a cloaca. Advertisement Homosexual behaviour is common in birds, but in this case it was probably due to mistaken identity, as male and female sand martins look the same. Following this observational period, the female budgies again chose between the two potential mates. The Yamashina researchers think the event they witnessed occurred because the dead bird happened to end up in a pose resembling the female mating position. It was brave of the biologists in Japan to do so, he says.

Scientists with the Konrad Lorenz Institute of Ethology in Great Britain captured female blue tits just after their eggs hatched. Females may be socially connected to one male, but they are always on the alert for a better offer, and it frequently comes from the guy next door. When the hanky panky is over, preen a little. But in Darwinian terms, the recipe for reproduction is far more clinical, with animals seeking mates based on the potential evolutionary advantage—often superior cognition skills—offered by a match. Can they do it in the air? And here's the switch: Scientists who have been aware of the infidelity among birds have generally thought that the males were the real cheaters, possibly because most of the scientists were men. Past studies structured this way have shown that females will gravitate toward males with beautiful feathers or skilled singing, as two behavioral experts not involved in the study, Georg Striedter and Nancy Burley—both from the University of California, Irvine—explain in an editorial analyzing the new study that was also published in Science. These researchers collected 1, eggs from blue tit nests to determine their hatching order. Unlike mammals, most male birds don't have penises. The female bird has a unique ability to influence which eggs hatch first. Instead, both male and female birds have what's known as a cloaca.

Ever since Charles Darwin postulated it would be to a bird's evolutionary advantage to stick with the same mate for its entire life, poets and novelists and even scientists have thought that meant they would remain faithful to the same mate, both sexually and socially. They have now published an article describing the incident — only the second paper describing such behaviour in birds. Follow LiveScience livescience. But their paper is too similar to his to merit an Ignobel, according to Moeliker, who is now on the Ig Nobel committee.
