The Common Grackle also known by its Latin name Quiscalus Quiscula, which translates to "Grackles Grackle". The male is generally larger than the female. Although they both commonly have a dark, large bill, yellow eyes, and a long tail as adults. It's feathers are colors ranging from black, green, purple, and blue. Though it looks black from a distance the rest of its body  is bronze. These gregarious birds have been known to to devastate corn stock and when they're not ruining a farmers day they are stealing from other birds. In other cases Common Grackles have been known to eat other adult birds along with insects as well, which makes an omnivore. Though having its population in the millions its population has seen a decrease of 2% every year from 1966-2014. They still stay on the list of least concern even though this decline accounted for 58% of their population. Right now they are most common in Northern America thriving in the eastern side of the U.S..

American Goldfinch

The American Goldfinch is the state bird of Washington, New Jersey and Iowa. It was adopted by the state of Washington in 1951. The American Goldfinch is also called wild-canary because of the sounds it makes. Goldfinches have a bounce to them when they fly because they tighten their wings close to their bodies for about a second or two. They do this so they can rest while they're flying. The American Goldfinch eats thistle seed which is their favorite seed to eat. Lastly the American Goldfinch is least concerned and their population is growing and they are sexually dimorphic.

The House Sparrow

The House Sparrow, also known as Passer domesticus (passer is latin for 'sparrow' and domesticus is latin for 'house'), is famously known for living comfortably among humans. Though they are not officially domesticated, they will eat from the hand of a human and have come to depend on humans for nesting. House Sparrows are about 15 to 17 centimeters tall, weigh about 27-30 grams, and their wingspan is about 19-25 centimeters wide. House sparrows are sexually dimorphic which means that the male and female look different. The male has a chestnut colored back with black and white streaks. They also have a grey cap on their heads. Finally, they have a very noticeable black mark on their chests that indicates that they are a dominant breeding male. Females have brown backs with black stripes. They also have grayish brown underbellies. House sparrows can be found anywhere that humans are which pretty much means they are all over the world. They are in every continent except for Antarctica. They live in both rural and urban areas. Their status is low concern even though their population has decreased. House Sparrows hop around urban areas in flocks looking for food. Males will be more dominant in the winter and fall while the females will be more dominant in the spring and summer. House Sparrows both water and dust bathe. They eat seeds,  crops, and anything else that they can find in terms of discarded human foods. To attract a female, they will fluff up their feathers, hop up and down towards her and bow up and down before her. House sparrows are considered an invasive species because the kill other birds to take their nests. This is a reason why many people don't like them in their backyards, because they kill off native species.

The American Crow

See the source image
The American Crow is one of the most intelligent animals in the world. They have a teamwork type of mindset, they solve problems and situations as a team. One behavior they are popular for is mobbing different animals or different species of birds. They do this to protect themselves, defend their territories and to teach their young about the dangers that surround the area. American Crows are not sexually dimorphic the male and female both have dark black feathers on their body the only difference is that the male is a little bigger. American Crows are omnivores so they will eat anything which is a problem for citizens in suburban areas since they trash peoples trash cans and yards. American Crows will lay their eggs in a nest but they prefer to make their nest in evergreens if available. During the breeding season, they will migrate to North American and Southern Canada but year-long they will stay throughout the United States. At this moment American Crows are at a low concern and are learning to adapt to suburban areas.

Rock Pigeon



The Rock Pigeon a.k.a the rock dove is a relatively medium-sized birds. Rock pigeons usually have  different colors and pattern but the majority of birds are bluish gray with black bands on the wing and iridescent throat feathers. Also they are not sexually dimorphic. Rock Pigeons often operate in flocks, so help each other point out food and alarm others when there is danger. Because these birds are foragers you will usually see a flock of rock pigeons eating seeds, grain, and anything they find on the ground. Also they live all over North America and Southern Canada year-round, so you can actually see in most places, especially urban areas. Something special about these birds is that they can find their way home, even if released from a distant location blindfolded. They do this by sensing the earth’s magnetic fields, and perhaps also by using sound and smell. They can also use cues based on the position of the sun.

Canada Goose

The Canada Goose also known as Branta Canadensis (Branta meaning wild geese, and Canadensis meaning of canada) is one of the most common birds in North America. Canada Geese are big water birds with a long neck, large body, webbed feet, and wide, flat bill. They're somewhat between 30 and 43 inches in length, weigh around 6 to 20 pounds, and have a wingspan of 50 to 70 inches. Canada Geese are not sexually dimorphic, meaning there are no distinctive traits to distinguish between the male and female. Canada Geese feed by dabbling in the water or grazing fields and large lawns. Usually females select and build nests. The male guards the nest while the female incubates the eggs. Canada Geese are often seen in flight moving in a V formation. This arrangement is called a "wedge." In this "wedge," there's a leading position in which is rotated because it is very tiring. This is one of the reasons why Canada Geese are able to travel 2,400 km in one day. They live in many habitats near water, grassy fields, and grain fields. They are drawn to lawns for two reasons, so they can digest grass, and because lawns give them a wide view of any approaching predators. When it comes to food, they should not be eat bread, because bread does not have much nutritional value for these birds. Although during the spring and summer, geese concentrate their feeding on grasses and sedges, including skunk cabbage leaves and eel grass. During fall and winter, they tend to rely more on berries and seeds. Their status seems to be a low concern mainly because their numbers are high, and they keep on increasing. Roughly around 2.6 million Canada Geese are harvested by hunters in North America but somehow this doesn't seem to affect its numbers.
