The American Robin is one of the more popular birds around. They are known for their warm orange breast, cheery song, and early appearance at the end of winter. I chose this bird because they are so commonly found in locations around me. One specific location was my backyard. Just at the end of spring a male and female robin moved into my backyard, where they began to build a nest and hopefully later make a family of their own. The American Robin is in the phylum Chordata, class Aves, and order Passeriformes. They also are classified under family Turdidae, genus Turdus, and species T. migratorius. Robins usually measure out to be 7.9-11 inches long with a wingspan of 12.2-15.7 inches. While also weighing in at 77-85 grams. They happen …show more content…
They defend the nests and sing while he waits for his mate (Howell 1942). When individuals arrive, testes containing developing spermatocytes and ovarian follicles become enlarged (Kemper and Taylor 1981). Males and females tend to chose mated based off plumage. One of the most interesting things I found was that mates choose their counterparts based off how similar they are to themselves, regarding breast color (Rowe and Weatherhead 2011). In my observations, the couple living on my property both had similar colored chests, so I could relate to those findings. It has been found that females construct the nest, for the most part. The process of making the nest usually take up to two weeks to make (Kendeigh 1952, Young 1955). In my findings, I can confirm that I often saw the male carrying twigs and branches to the nest site, while the female built up the nest The male was seen dropping off material for the nest and then would fly back out. Since my observations were obviously in the summer, I made sure to research on what robins are up to during the winter. During winter nights, they assemble in large flocks at night in trees in isolated swamps or dense vegetation. On the other hand, during the day the flock breaks up and the birds feed on berries and fruits in smaller …show more content…
All these occasions involved earthworms and each occurrence seemed to involve the male carrying these earthworms back to the nest. I later found that in early summer days, robins have insects make up the majority of their diets. Besides earthworms, I learned that they will feed on snails, spiders, and other invertebrates. Fruit also apparently makes up 60% of their diet year round, with an abundant amount eaten in the winter. Robins use their bills to probe the ground and soil, as well as move twigs, leaves, and other objects that could be used (Vanderhoff and Eason 2008). Robins use uncomplicated tactics to catch their
The Australian King Parrot puts their nest in a deep hollow in a tree trunk that is 10m off the ground. The female will lay her eggs in the hole on decayed wood-dust at 0.5m off the ground.
They are very secretive birds. They rarely hunt before dark. When they hunt they make silent, low passes over and open place and then they snatch their prey. They eat small rodents like mice, voles, and rats. They occasionally eat young rabbits and small birds and snakes. Roosting, or resting for sleep, is usually done in the thick parts of the trees where they can camouflage and hide. Communities of owls often roost together in the winter. Long-eared Owls can make a wide variety of hoots, squeaks, and barks. They can even clap their wings! Long-eared Owls require a combination of grassland and other open country for hunting and dense tall shrubs or thick trees for nesting and roosting. Their favorite winter habitats are pine and fir
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
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
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
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
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.
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
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
Although they come in all kinds of colors and shapes, all birds have feathers and lay eggs.
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.
The Habitat of the Albatross is mainly the sky, so to speak, as it spends most of its lifetime gliding through the air. This is also supported by the Albatross’ tapered wings, which allows the bird to use the wind efficiently. Congregations of Albatrosses on land are rare except for when it is breeding season; they then reside on remote islands for a number of months to mate and care for their clutch.
Severely restricted inside the barren cages, the birds are unable to engage in nearly any of their natural habits, including nesting, perching, walking, dust bathing, foraging, or even spreading their wings” (HSUS, 2009).
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.
