Male birds store sperm in their cloaca until an opportunity to mate arises, and females will receive that sperm into their cloaca before it travels deeper into their bodies to fertilize their ova and begin egg formation. The courtship between a pair of birds can last much longer than the actual act of copulation.
Courtship behavior may include several stages, from initially claiming territory to actually wooing a prospective mate with visual and auditory displays such as stunning plumage, spectacular flights, intricate songs , or even elaborate dances. The courtship period is when a male bird shows off his health and strength to convince a female that he is her best possible mate and will help her create the strongest, healthiest chicks with the best chance to survive.
Once a female bird is receptive to a mate, whether it is a new mate every breeding season or simply renewing ties with a life-long partner , the actual mating can take place. The positions and postures birds assume to mate can vary, but the most common is for the male bird to balance on top of the female. The female may hunch, lay down, or bow to give the male easier balance, and both birds face the same direction.
She will then move her tail aside to expose her cloaca to his reach, and he will arch or curl his body so his cloaca can touch hers. The brief rubbing of cloacas may last less than a second, but the sperm is transferred quickly during this "cloacal kiss" and the mating is complete.
The balancing may take longer as the birds stay touching one another, and several "kisses" might occur within a few moments. Birds will remain excited by their hormones for a week or more and may mate several times during that period to increase the chances of successful insemination.
Some bird species, most notably several species of swans , geese, and ducks , do not have cloacas, but instead male birds have an actual phallus penis that is inserted into the female during mating. The penis is formed by an extension of the cloacal wall, and unlike mammals, is erected by lymph rather than blood. Having a penis helps different types of waterfowl mate in the water without the sperm washing away from an exposed cloaca.
In return, the loud alarm calls of the geese alert the peregrine, which has its own chicks to protect. The swooping vicious attacks of the peregrine falcon soon deter the fox from coming any nearer. Another ploy is to employ insects as "guard dogs". The rufous naped wren builds next to wasps' nests for protection.
The rufous woodpecker [different species, despite the similarity of names] nests in the middle of an ants' colony.
The ants' fury soon subsides and is transferred to any intruder that tries to steal the eggs Some birds do without a nest altogether. The Emperor penguin, which breeds in the middle of the Antarctic ice cap, where temperatures drop as low as C, is the only species of bird to lay its eggs directly on to snow.
There are other birds that dispense with every convention of home making and parenthood, and resort to cunning to raise their families. These are the "brood parasites," birds which never build their own nests and instead lays their eggs in the nest of another species, leaving those parents to care for its young.
Red breasted geese. The cuckoo is the best known brood parasite, an expert in the art of cruel deception. Its strategy involves stealth, surprise and speed.
The mother removes one egg laid by the host mother, lays her own and flies off with the host egg in her bill. The whole process takes barely ten seconds. Cuckoos parasitize the nests of a large variety of bird species and carefully mimic the colour and pattern of their own eggs to match that of their hosts. Each female cuckoo specializes on one particular host species. How the cuckoo manages to lay eggs to imitate each host's eggs so accurately is one of nature's main mysteries.
Many bird species learn to recognize a cuckoo egg dumped in their own nest and either throw out the strange egg or desert the nest to start afresh. So the cuckoo constantly tries to improve its mimicry of its hosts' eggs, while the hosts try to find ways of detecting the parasitic egg.
One of the most extraordinary examples of deception is practiced by the screaming cowbird. This bird only dumps its eggs in the nests of bay-winged cowbirds. Unlike in any other known brood parasites, the screaming cowbird chicks are absolutely identical to the chicks of the host at the stage when they are dependent on the parents for food, Then, as soon as they fledge, they take on the plumage of their own species.
Another bird that gets away with great deception is the whydah, an African bird with a remarkably long tail. It dump its eggs into the nests of little finches. But the whydah chick does not evict its nest mates; instead it grows up with them. The whydah chick looks completely different from the host nestlings.
But when it opens its mouth, the resemblance is remarkable - the young whydah has a gape and mouth spots that closely mimic those of its nest mates. The hard-working parents see no difference in the row of open mouths and feeds them all equally. The struggle between host and parasite is akin to an arms race, each trying to out-survive the other. When the gnatcatcher realises the cowbird has laid in its nest, it takes the extreme step of tearing the whole place apart, destroying its and the intruder's eggs in the process.
Then it starts all over again. We hear much about manipulative youngsters in human society. But the young of some birds manage to manipulate their parents even before they leave the egg. The chicks of the American white pelican tell their parents when they are too hot or too cold by giving loud and clear distress calls from inside the eggs. This helps the parents incubate the eggs correctly; they respond to the calls by turning and re-settling on the egg.
The greater honeyguide in Kenya is another parasite. It lays its eggs in the nests of the red-throated bee-eater. But its chicks, when they hatch, have a deadly advantage.
They are armed with a murderous hook-tipped bill. The chicks of the red-throated bee-eater die under the vicious attacks of the honeyguide chick within the first few days of hatching. The murder weapon then drops off, its purpose achieved.
The foster parents now devote all their energy towards feeding the killer of their own young. The black eagle, which nests on cliff ledges in Africa, is a species whose second chick is always doomed.
It always lay 2 eggs.
