Research Paper On American Robin

For reproduction it is best to place one male in with 2-3 females. This will lower the rate of fighting compared to a one on one. Then the female will typically make a burrow 6-8 in. deep and lay her eggs there. The eggs will hatch about 60-70 days

Mating occurs before sunrise and mates are found by scents. When the female lays her eggs it forms a stick that contains thirty to fifty eggs. They hatch after about twenty-five days and they eat the cactus pad. After about two moths in the host cactus they exit the cactus and form cocoons. They become a pupa under the debris on the ground. Once they reach the moth stage they search for a

They place their nest in places where other animals and predators can't get it near water.They usually produce 2-7 white eggs. Both the male and female help sit on the eggs , which lasts for 43 - 46 days until the eggs hatch.The offspring are able to leave soon after hatching; but the parents will take care for them for weeks.They usually take to the sky for the first time when they are about 8 - 14 weeks

The habitat that the Red Cockaded Woodpecker lives in is the the lives in a pine forest but to be more specific they live in longleaf pines

The Canadian goose is a large water bird measuring at 76-110cm long and weighing 3000-9000g. It has a long neck, a large body, a wide and flat bill, and large webbed feet. It has a black body with white cheeks and chin strap, a black neck, a tan breast, and a brown back. Its wingspan is 127-170 cm.

Mating season starts after hibernation, between May and July. The female alone takes the role of raising the litter, which could have up to ten offspring. The spines gradually but in a short time begin to develop. At birth, the offspring is blind and has a layer of barely developed spines

They build their nests are on the ground using moss and grass.. After the female is fertilized the egg grows inside her. When the egg is laid the male and female take turns sitting on the egg for two months. The chicks stay under the constant protection of their nesting parents for the first three or four weeks of their life. Later when they are stronger, they are left alone for days or weeks at a time while their parents go to get them food. The parents need to pre digest the food because the weight of the undigested food would make them so heavy they would not be able to travel.. The chicks grow so much while there parents are away that their parents don’t recognize them by sight when they return so the must rely on calls and their sense of smell to identify their own chicks and feed them their predigested oily food.

With an average wing span of eleven feet and a weight of up to twenty-two pounds,

Although they come in all kinds of colors and shapes, all birds have feathers and lay eggs.

Their nest sites are among marsh vegetation in shallow water (sometimes up to 3 feet deep), sometimes on dry ground close to water. The nest (built by both sexes) is a mound of plant material pulled up from around the site; it may be built up from bottom or may be floating, anchored to standing plants. Females typically lay two eggs, which both parents incubate. Males take responsibility for defending the

says females will guard the nest, but they found that there is no relatedness between closely nesting females. It was also found that multiple clutches in the wild contained offspring that had the same mother but different fathers. As females only produce one clutch a season, have no sperm storage that is known about, and are known to have loose social nesting groups it is likely that the results of microsatellite testing truly indicate females breed with multiple males. The AZA Regional Collection Plan (2012) says that in June nest building can be synchronized within a population.

On the Galapagos Islands, there are many unusual birds. One of the most strange is the sharp-beaked finch. This bird lands on the backs of larger birds and pecks them until blood comes. Then it drinks the blood thirstily. Scientists think that this started with the removal of parasites and bugs, but, discouragingly, it has turned into a direct attack on the larger birds. The sharp-beaked finch, which is only the size of a robin, is aggressive in other ways as well. It flies to other birds nests, and then pushes the eggs off the side to plunder to their doom. As soon as they hit the ground, the eggs break into bits. Obviously, they have the disadvantage. The sharp-beaked finch flies down to meet it's

Robins were actually quite rare when settlers first came to the United States. Their relatives, the family of thrushes, all lived in the forests. However, the robin was a specialized bird and stayed near the clearings among the trees. As the settlers moved west, the robins joined them and became the ubiquitous symbol of the suburban backyard wildlife across the entire United States and Canada. Now most robins prefer the suburban lifestyle with the evenly manicured yards and openly spaced trees.

The callow, forager, gyne and queen in M. pharaonis all have different tasks within the colony and display different behavior. The callow tends to stay inside the nest and tend the brood. The forager tend to leave the nest and forage for food (Mikheyev & Linksvayer, 2015). Gynes are usually stay in the nest until they mature and fly outside the nest to mate and the queens stay inside the nest and lay eggs. All four phenotypes have different needs linked to their specific tasks and locations. For example, foragers would require higher coordination and memory skills than queens would, as they have to navigate around outside the nest, and gynes would require higher visual abilities than callows, for mating purposes.

Bobolinks, like me, inhabit low-intensity agriculture habitats. For example, hayfields, meadows, and high grasses. We prefer to build our nests in places with great height and density. Speaking of nests, us Bobolink men make the nests, while the female Bobolinks lay eggs. That is how we all come to life! The women also keep the baby birds safe. However, unlike humans the women don’t give birth to us. They lay the eggs in order for us to come to life and be our beautiful
