Here, distinctive habitats harbor a captivating range of bird life, offering an avian symphony that mirrors the ecological richness of the area.

Most Common Bird
1. Song Sparrow
The song Sparrow can be found low to the ground in vegetation and thickets in nearly all habitat conditions, including suburban areas. They are frequent visitors to home birdfeeders but can also be seen foraging for food on the ground. Their appearance can differ across the 24 known subspecies, but all of them tend to only make short, fluttery flights.
2. American Crow
The american Crow is a big black bird that can be found in forests, fields, river groves, and among human habitations. Interestingly, it is known to stand atop ant hills and allow ants to climb onto its feathers; this apparently discharges their formic acid and makes them more palatable for the crow to eat. Sadly, american Crow numbers have been substantially affected by the West Nile virus in North America. Infected birds die from West Nile in less than a week.
3. Dark-eyed Junco
One of the most common birds of North America, the dark-eyed Junco lives in flocks in open forests, but it's very common in urban areas. This a highly variable species consists of at least five subspecies. This ground bird is often seen during winter, so it's sometimes called the "Snowbird," although it shares the nickname with the Snow bunting (Plectrophenax nivalis).
4. Black-capped Chickadee
This small songbird is the most common garden bird in Canada and the northern USA, and also one of the most scientifically studied birds in the world. Able to produce more than 15 complex sounds, the black-capped Chickadee can easily confuse predators with its calls. It's a clever, skillful, and adaptable bird—it can retrieve hidden food after a month and it's able to fly even when its body temperature drops.
5. Anna's Hummingbird
This hardy bird is a common sight along the Pacific Coast, with a bright, vibrant coloring that is anything but common. Look for their emerald feathers and soft pink throats, which gives them the appearance of a flying jewel. Anna's Hummingbird is more vocal than other hummingbirds, with a buzzy song you may hear from the males when they are perched.
6. American Robin
The american Robin is the most common, and largest, thrush in North America. It's a bird of striking colors, including its vibrant, red-breasted plumage and pale blue eggs. It likes to feed on summer fruit and berries, but worms play an important role in its diet as well. This songbird is a state bird of Connecticut, Michigan, and Wisconsin. Its cheery song is considered one of the first signs of spring.
7. Spotted Towhee
The spotted Towhee is a large sparrow found in sunny, open forests and recognizable by its distinctive two-footed hop. A ground dweller, it scratches the ground in search of food. Regarded as an extremely vocal bird, its song varies according to geographical location. During the breeding season, the male spends more than 70% of its mornings singing, trying to attract the female.
8. Northern Flicker
In the search of its favorite food—ants—the northern Flicker often forages leaf litter and tree bark, which makes it the only ground forager in the woodpecker group. It's a migratory species, which is quite a rare behavior for woodpeckers, as well. The northern Flicker has an eastern (yellow-shafted) and a western (red-shafted) form. It lays a large number of eggs - the known record is 71 eggs in 73 days.
9. House Finch
Frequent in urban environments and human-created habitats such as parks and backyards, the little house Finch is known for its loud but pleasant, cheerful singing. It feeds on the ground, mostly on seeds, berries, and other plant material. This bird is highly sociable and very adaptable. It often visits feeders.
10. Mallard
The mallard is the most abundant duck species in the world, and the ancestor of all domestic ducks. Only the female can produce the distinctive "quack" sound. When the female lays eggs, the male abandons its mate, while the protective mother stays with the ducklings for a long time. This migratory species inhabits shallow waters and it's one of the most popular game birds.
11. California Scrub-jay
California Scrub-jays prefer to live in dry shrublands, oak forests, and treed backyards. These are mischievous little birds that like to steal acorns from Woodpecker hiding spots. However, when the scrub jays hide the acorns in a new spot they rarely remember where they've hidden them! It's a lose-lose situation. When not stealing acorns they like to spend time eating ticks and other parasites off the backs of mule deer. The deer seem to appreciate the attention and often hold up their ears to give the jays access.
12. Red-breasted Nuthatch
Short and round, the tiny red-breasted Nuthatch attracts notice with its high energy level and the black and white striping on its head. Look for it this little active bird at your bird feeder, or listen for a “yank-yank” call, similar to the sound of a small tin horn honking. This bird is known to collect resin from trees and plaster it in front of its nest as a way to ward off predators.
13. Lesser Goldfinch
A common visitor of birdhouses or anywhere with birdseed, the lesser Goldfinch is a small, notch-tailed bird that enjoys gardens and open wooded areas. Its size has made it commonly overlooked, but listen out for its charming, chiming song. Social birds, they are often seen in large groups of hundreds traveling together at a time.
14. Canada Goose
Though this large, widespread bird is mainly known for its aggressively territorial nature, often shown by spitting, chasing, honking, or attacking, the canada Goose does have more loving traits. They mate for life, and this species is one of the birds that has minimal “divorce rates.” Interestingly, they choose mates by size, so smaller geese will mate with other small geese, and larger geese with other large geese.
15. Bewick's Wren
The Bewick's wren has an average length of 5.1 inches (13 cm) an average weight of 0.3 to 0.4 ounces (8 -12 g), and a wingspan of 18 cm. Its plumage is brown on top and light grey underneath, with a white stripe above each eye. Its beak is long, slender, and slightly curved. Its most distinctive feature is its long tail with black bars and white corners. It moves its tail around frequently, making this feature even more obvious for observers. Juveniles look similar to adults, with only a few key differences. Their beaks are usually shorter and stockier. In addition, their underbelly might feature some faint speckling. Males and females are very similar in appearance. 
16. Red-winged Blackbird
One of the earliest spring harbingers in North America, the red-winged Blackbird migrates in enormous flocks. Gathered in these large groups, the songbirds produce a loud cacophony. The red-winged Blackbird is an opportunistic omnivore. It feeds on numerous insect species, keeping pests under control, but due to its preference for crops and berries, the red-winged Blackbird is sometimes considered a pest itself.
17. European Starling
The european Starling, a large, hardy songbird, is one of the most commonly seen bird species in North America. Originally from Europe, this species was brought to the U.S. in the 1890s by enthusiasts of William Shakespeare, who had the unique goal of bringing over every single species of bird that was mentioned in Shakespeare's collective works. Unfortunately, the european Starling, being an adaptable, generalist species, spread invasively across the continent, hurting many native species' populations in the process.
18. Steller's Jay
Steller's Jays are loud, large jays that live mostly in evergreen forests. Their "song" is a horrible screeching call, but they are also great mimics that can copy the sounds of other birds, dogs, cats, chickens, etc. Notorious nest-robbers, they are well-known for attacking and killing small adult birds, nestlings, and taking off with other birds' eggs.
19. Bushtit
The social bushtit can often be found in deciduous and mixed forests as well as in home gardens and backyards. They have a characteristic upside-down feeding behavior as they search for spiders and insects on the undersides of leaves. These birds like to decorate their nests with flowers and lichens.
20. Great Blue Heron
The great Blue Heron, the largest such bird in North America, is quite adaptable and thrives in various wet habitats. Silent, patient, and often motionless, this majestic bird always makes a spectacular sight. Thanks to its specially shaped neck and extremely good night vision, this wading bird is a quick and skilled fish predator. Since the great Blue Heron accumulates toxins in its body, researchers use it as an indicator of dangerous contaminants in local wetlands.
