The Northern Cardinal is an iconic North American bird, easily recognized by its vibrant color and melodious song.

Appearance: Male Northern Cardinals are a brilliant scarlet red, while females display a more subdued reddish olive. Both sexes have a distinctive black ‘mask’ on their face around the bill and a pointed crest on their head. The bird’s beak is robust, cone-shaped, and bright orange in color.

Diet: Northern Cardinals are primarily granivorous, with a diet largely consisting of seeds and grains. They also eat fruits and insects. These birds typically feed off the ground and are frequent visitors to bird feeders.

Reproduction: Northern Cardinals are monogamous, and a pair will breed together for life. The female typically builds a well-hidden nest in a dense thicket or shrub. She lays 2-5 eggs per clutch, which she incubates for around two weeks.

The Summer Tanager is a medium-sized songbird admired for its radiant plumage and melodious song.

Appearance: Male Summer Tanagers are an impressive bright red, while females and juveniles present a softer, yellow-orange color. Both genders have a large, slightly hooked bill and relatively short tail.

Diet: Summer Tanagers primarily feed on insects, including bees and wasps, which they catch in flight or pick off vegetation. They are also known to eat fruits and berries, making them helpful in controlling pest populations and seed dispersal.

Reproduction: The female Summer Tanager builds a loose, shallow cup-shaped nest out of twigs and grass, usually hidden in the foliage of trees. The female typically lays 3-5 eggs, which she will incubate for about two weeks.

The Western Tanager is a vibrant songbird that graces the forests and woodlands of the western regions of North America, enchanting observers with its colorful plumage and melodious song.

Appearance: The male Western Tanager is renowned for its bright yellow body contrasted with a striking red head and black wings and tail. The females are more subdued in hue, primarily being yellow with grayish wings and back, and lacking the brilliant red head of the males.

Diet: Western Tanagers primarily feed on insects, especially when breeding, but they also incorporate a significant amount of fruits and berries into their diet, especially during migration and winter.

Reproduction: Western Tanagers build their nests high in coniferous trees, often well concealed from potential predators. The female usually lays a clutch of 3 to 5 eggs and takes the primary role in incubation, while both parents are involved in feeding the chicks after they hatch.

The House Finch is a small songbird widely distributed across North America and is commonly found in urban and suburban areas.

Appearance: Males of this species are brightly colored with crimson faces and throats, which can extend to the chest and back, while their flanks have streaks. The female is streaked brown and lacks the red coloring. Both have a square-tipped tail and a distinctively long, flat-topped bill.

Diet: House Finches primarily eat seeds, grains, and berries. They have a particular fondness for sunflower seeds and can be commonly seen at bird feeders. Occasionally, they will also consume insects, especially during the breeding season.

Reproduction: House Finches are cavity-nesters and might choose ledges, vents, ledges, and other urban settings. They might also utilize trees or shrubs. Their nests can be made of a wide array of materials, from feathers to twigs.

The Cassin’s Finch is a small songbird known for its melodic song and affinity for high-elevation forests.

Appearance: Male Cassin’s Finches are pinkish-red on the crown and throat, contrasting with their streaked brown back and wings. Females lack the bright coloring, appearing streaked brown throughout with a pale eyebrow stripe. Both sexes have a notched tail and a slightly curved bill.

Diet: Cassin’s Finches mainly feed on seeds, particularly from conifers. They also eat insects, especially during the breeding season. Their feeding habits often bring them to bird feeders where they readily eat sunflower seeds.

Reproduction: Cassin’s Finches nest in trees, preferring coniferous forests. The nest is made from twigs, grasses, and feathers. Typically, the female lays 3 to 5 eggs and handles most of the incubation. Both parents partake in feeding the fledglings once they hatch.

The Pine Grosbeak is a striking bird native to the northern regions of North America, often found in coniferous forests. Both males and females have a plump and robust body with a large beak adapted for eating seeds. The male Pine Grosbeak displays a vibrant reddish-pink plumage, while the female has a more subdued grayish-brown coloration.

These birds are typically seen in small flocks, foraging for food in trees and on the ground. They have a preference for seeds, particularly those from various conifer species. The Pine Grosbeak uses its strong bill to crack open the cones of tall trees and extract the seeds, but they also consume berries and small fruits when available.

The Red Crossbill is a distinctive finch known for its unusual bill, which has evolved to extract seeds from conifer cones.

Appearance: Males are typically bright red or orange, while females are greenish-yellow or olive. Both genders have the characteristic crossed bill, which they use to expertly extract seeds from tightly closed conifer cones.

Diet: Red Crossbills primarily feed on the seeds of coniferous trees, such as spruce, pine, and fir. Their specialized bills allow them to efficiently pry apart conifer cone scales to access the seeds.

Reproduction: Red Crossbills are somewhat nomadic and don’t adhere to a strict breeding schedule. Instead, they breed whenever and wherever food is abundant. Their nests are usually built on horizontal branches of conifer trees.

The Rufous-sided Towhee, more commonly known as the Eastern Towhee, is a striking bird distinguished by its vivid coloration and melodious calls.

Appearance: Male Eastern Towhees are characterized by their black upper bodies, rufous flanks, and white underbellies. Females share the same pattern but are brown where the males are black. Both sexes have a distinctive red eye.

Diet: Eastern Towhees primarily feed on the ground, rummaging through leaf litter for seeds, berries, and insects. Their diet can vary seasonally, with more insects in warmer months and seeds during winter.

Reproduction: Eastern Towhees nest on or near the ground, typically in shrubs or dense vegetation. The female constructs the nest and incubates a clutch of 2 to 5 eggs, which hatch after about 12 days.

The Red-Winged Blackbird is a familiar sight across North America, especially in wetlands and open areas. Known for its striking coloration and distinct call, it is often seen perched on cattails or utility lines.

Appearance: Male Red-Winged Blackbirds are glossy black with bright red-and-yellow shoulder patches, while females are streaky brown, resembling a large sparrow. The males’ red patches become more prominent when they’re displaying or agitated.

Diet: Red-Winged Blackbirds primarily feed on seeds and insects. Their diet includes grains, sunflower seeds, and corn, but they also eat beetles, caterpillars, and other small invertebrates, especially in the breeding season.

Reproduction: Red-Winged Blackbirds nest in marshes, along watercourses, and in wet fields. The female constructs a cup-shaped nest using grass and sedge, attaching it to plants above water. She typically lays a clutch of 3 to 4 blue-green eggs, which she incubates for about 11-12 days. Males, being polygynous, often have multiple mates during a single breeding season.
