With over 60 species of eagles, there are no common breeding patterns shared by all of the species. The two more commonly known types of eagles, golden eagles and bald eagles, have intricate courtship displays. Both eagles are known to mate for life, although bald eagles do sometimes take another mate.Continue Reading
When mature female bald eagles are looking for a mate, they are more docile than normal. Sometimes a bald eagle looking for a mate flies to a great height and dives until almost hitting the ground and then pulls up. When bald eagles are interested in each other, the eagles perch together and groom and stroke one another. Courtship also involves the pair locking talons and going into a free fall. The pair then pull apart before they hit the ground. The actual mating occurs with the male standing on the female's back; the male twists his body so that their cloacas can touch.
Golden eagle males mate by taking a rock up into the air, dropping it, and then catching it in mid-air. The female then does the same with a clump of Earth or a small stick. This display is only done once in the life of the pair, unlike bald eagles who repeat courtship every year. Golden eagles also sometimes lock talons, like bald eagles, but that behavior is rare. The act of mating occurs in the same fashion as in bald eagles; the male stands on the female and they touch cloacas.Learn more about Animal Reproduction
There are few observable traits distinguishing migrating animals from non-migratory species. Many birds, such as Arctic terns, mallards and bar-tailed godwits migrate across vast distances, while some of their close relatives remain in the same place all year. There are species of birds, fish, mammals, and even reptiles and amphibians that migrate each year.Full Answer >
Insects that lay eggs are called orthopterans, which consist of common species such as praying mantis, cockroaches, crickets and grasshoppers. Although these insects all lay eggs, they have different methods of carrying out the egg laying process. All egg-producing insects have distinct methods of carrying, hatching and raising their young.Full Answer >
Platyhelminthes, also known as flatworms, are hermaphrodites, meaning individuals of the species produce both sperm and eggs. These are released from the platyhelminthes where they become cross-fertilized by other platyhelminthes. Two types of platyhelminthes, trematoda and cestoda, lay eggs constantly. The turbellarian class has a seasonal cycle. Turbellaria also reproduce asexually by dividing. Turbellaria are the only class able to regenerate body parts.Full Answer >
When two animals of a different species mate, they are usually too genetically different to produce an offspring. If the two species are genetically similar, they may be able to produce a hybrid offspring, such as when a horse and a donkey breed and create a mule.Full Answer >
