Blue Jays are how we know them, but the Blue Jay has a scientific name, they are called Cyanocitta cristata. After 8-12 day of incubation the eggs hatch. Newborn Blue Jays live in the nest for 17 through 21 days, when they are ready to fly. Newborn Blue Jays leave the nest flying; taking their own adventure in life. Blue Jay parents leave the nest when they hear predators, to take them far from the nest so they cannot identify the nest. Blue Jays are related to crowns, robin, and magpies. Blue Jays have a wonderful blue color that comes from the internal parts in the feather. The blue jays length is 9.8–11.8 in and 25–30 cm, weight 2.5–3.5 oz and 70–100 g, wingspan 13.4–16.9 in and 34–43 cm. The blue jays eggs are yellowish, sometimes brown …show more content…
Female and male blue jays bring food to the nest, but mostly the male does the job. Blue Jays become quiet during the nest, only make loud noise when they notice the nest is in danger. Blue Jays are Omnivorous. Blue Jays diet is 75% vegetable including nuts and fruits. Blue Jays have small diet of insect and animals, few of them are caterpillars, beetles, grasshoppers, spiders and snail and sometimes add small rodents, frogs and baby birds. Blue Jay collect nuts open them with their beak and keep their nuts under the ground. Blue Jays can hold food in there esophagus and carry food in their beak. The blue jays immigrate long distances. There is 20% or less of young and adult blue jays during immigration. They immigrate in groups, some immigrate in spring. The blue jays are very curious. In 2016 the oldest blue jays was found death in the wood. Blue Jays population decreased 28% between 1966 and 2015. Blue Jay population is 13 million, 87% live in United Sated and 13% live in Canada. Blue Jay is a prey and their predators are hawks, falcons, raccoons, cats, snakes, squirrels, and even humans. I learn a lot from this singer

Looking at Figure C, we can say more than 200,000 blue whales has been killed as results of overhunting. In 1966, the International Whaling Commission banned commercial whaling for blue whales, but illegal hunting still occurs (NOAA). While blue whales are no longer being threatened by overhunting, their population is drastically depleted. Like many other marine species, blue whales are being harm by many others factors today. This include collisions of ships, chemical pollution such as oil spills, and noise pollution from vessels (Eco). The population of blue whales is known to be around “10,000 to 25,000 ” (World Wild Life).
The numbers of all "light" colored geese has been on the rise since data was first collected. The Lesser Snow Goose (LSGO) has drastically increased in number since data was first taken. Numbers range from around 800,000 in 1969 to as many as 6 million in 1996 (CWS 1999). While the Greater Snow Goose (GSGO) has risen in numbers from a few thousand to almost 500,000 (CWS 1999). This brief article did not provide much insight into actual numbers. Abraham and Jeffries in their report dig deeper and provide more significant and detailed population counts. Their numbers add in the Mid-winter index, which is the number of geese counted during mid-winter and referred to as MWI. Their numbers also have a count for Ross’ Goose (ROGO) which primarily flies with the (LSGO) and is very hard to distinguish (Abraham and Jeffries 1998). They too suggest the LSGO population to be aro...
American Crows can reach a length between 17 to 21 inches, with a wingspan of 39 inches, while the Common Raven is a larger bird that has an average length of 24 inches (Burton et al. 2010; Marzluff et al, 2013). Both the American Crow and the Common Raven have black coloration, but their feathers and beaks differ. Common Ravens have a larger, stronger beak, a wedge-shaped tail, and spikey feathers on their throat. American Crows, on the other hand, have a smaller and less bulky bill, smooth throat feathers, and they have tail feathers that fan out instead of forming a wedge (Marzluff et al, 2013). The two birds have different styles of flying.
They are all related to the colony because the queen ant is the mom to all of the ants. In the colony, every ant works for the welfare of the whole community. Each ant has its own work, and does it very well. Ants are everywhere, they can be a big problem for people when they invade the timber of a house, causing the wood to collapse. They even nest between walls.

The hornbill has a casque on top of its head, giving it its name. The casque is made of the same material of the bill itself. It is a black bird with a white stomach. The bottom of the wings are white as well. It has white around its eyes. The bird is typically 55-60 cm long. The male is 680-907 g in weight. Those are just a few of the characteristics of the hornbill.
