The 8 Species of Hawk in Connecticut
1. Sharp-shinned Hawk
Although highly migratory, the Sharp-shinned Hawk can be seen all year in Connecticut. They are not very common and are in 2% of bird sightings in Connecticut.
The Sharp-shinned Hawk is the smallest hawk in Connecticut. They are smaller than a crow but slightly larger than a Jay.
The females are a third bigger than the male. They have long tails, with a square end, and short, rounded wings and have small heads.
- Length: 9.4-13.4 in (24-34 cm)
- Weight: 3.1-7.7 oz (87-218 g)
- Wingspan: 16.9-22.1 in (43-56 cm)
Adult Sharp-shinned Hawks are blue-gray across the back and have a red-orange breast. They have dark bands across their tails.
They are very secretive but can be seen as they fly across open areas at the edges of forests. They are very agile and can speed through dense woods to catch their prey in flight, usually songbirds.
They can sometimes be seen near feeders catching small birds, but if you have problems with them in your backyard remove the feeder for a few weeks.
Sharp-shinned Hawks pluck their prey on a stump or low branch before eating it. They usually eat songbirds about the size of a robin.
Nests of the Sharp-shinned Hawk are often in conifer trees in dense cover, usually towards the top of tall trees. The nest is quite large being 1-2 feet in diameter and 4-6 inches deep. They lay 3-8 white or pale-blue mottled eggs.
2. Cooper’s Hawk
Cooper’s Hawks can be seen all year in Connecticut. They are more common woodland hawks than the Sharp-shinned Hawk. They have been sighted in around 4% of checklists in Connecticut.
- Length: 14.6-15.3 in (37-39 cm)
- Weight: 7.8-14.5 oz (220-410 g)
- Wingspan: 24.4-35.4 in (62-90 cm)
- Length: 16.5-17.7 in (42-45 cm)
- Weight: 11.6-24.0 oz (330-680 g)
- Wingspan: 29.5-35.4 in (75-90 cm)
Look out for them at the edge of forests, but they can also be seen at feeders looking for an easy meal. If you do have problems take down feeders for a week or two and the Hawk should have moved on.
The Cooper’s Hawk looks very similar to the Sharp-shinned Hawk but is bigger at about the size of a crow. They can be hard to identify between them as they have the same blue-gray back and red-orange breast and also with dark bands on the tail. They have a larger head that projects well beyond the wings, unlike the Sharp-shinned Hawk.
They feed on medium-sized birds and small mammals and nest in tall trees, often on top of an old nest of a large bird or clump of mistletoe. They lay 2-6 pale blue to bluish-white eggs.
3. Red-shouldered Hawk
The Red-shouldered Hawk can be found all year in Connecticut.
They tend to be seen near wet forests hunting along a stream or pond. Their prey is mammals and frogs or snakes.
- Length: 16.9-24.0 in (43-61 cm)
- Weight: 17.1-27.3 oz (486-774 g)
- Wingspan: 37.0-43.7 in (94-111 cm)
Red-shouldered Hawks are distinctly marked, with dark and white checkered wings and reddish barring on the breast. They are medium-sized, between the size of a crow and a swan with a strongly banded tail. They make a loud cack-cack-cack-cack call.
Nests are often reused each year in a broad-leaved tree near water. They lay 2-5 white or bluish eggs.
4. Broad-winged Hawk
Broad-winged Hawks breed in Connecticut, more often in the north of the state, before migrating in large numbers to South America in a swirling flock called a kettle. They are not often observed in Connecticut, being in less than 1.5% of recorded checklists on ebird.
The migration in fall is the best chance to see them.
The Broad-winged Hawk is a compact, stocky bird between the size of a crow and goose. They have reddish-brown heads, barred breasts, and narrowly banded short square tails.
- Length: 13.4-17.3 in (34-44 cm)
- Weight: 9.3-19.8 oz (265-560 g)
- Wingspan: 31.9-39.4 in (81-100 cm)
Hunting from a perch often on the edge of woods or by water, these hawks eat small mammals, frogs, snakes, and even young turtles.
The Broad-winged Hawk often reuses the nest of another animal, such as a crow or squirrel and lays 2-3 whitish eggs.
5. Red-tailed Hawks
Red-tailed Hawks can be found in Connecticut all year and are common, being seen in over 13% of sightings in Connecticut.
They are also the easiest to spot, often on long car journeys, as they circle slowly over open fields looking for prey. You can also see them perched on telephone poles.
- Length: 17.7-22.1 in (45-56 cm)
- Weight: 24.3-45.9 oz (690-1300 g)
- Wingspan: 44.9-52.4 in (114-133 cm)
- Length: 19.7-25.6 in (50-65 cm)
- Weight: 31.8-51.5 oz (900-1460 g)
- Wingspan: 44.9-52.4 in (114-133 cm)
As their name suggests, the Red-tailed Hawk has a distinctive short, wide red tail. They are large, with broad, rounded wings, between the size of a crow and goose. Most Red-tailed Hawks are brown on the back and pale underneath.
The high-pitched descending raspy-screech sound of the Red-tailed Hawk is often used in movies for all raptors. They eat small mammals, birds, and reptiles.
Nests are high in very tall trees or on cliff ledges and sometimes on tall buildings or towers. They lay 2-3 whitish, brown blotched eggs.
6. Rough-legged Hawk
Rough-legged Hawks migrate from the arctic and are found in Connecticut in the winter. They are not very common in Connecticut and are only seen in less than 1% of sightings.
Rough-legged Hawks are usually sighted hovering over marshes and open fields or perched on a pole.
- Length: 18.5-20.5 in (47-52 cm)
- Weight: 25.2-49.4 oz (715-1400 g)
- Wingspan: 52.0-54.3 in (132-138 cm)
The feathered legs give the Rough-legged Hawks their name and help to keep them warm in the arctic. They are fairly large hawks, between the size of a crow and a goose.
This predominantly dark-drown species occurs in both light and dark forms, with dark patches at the bend of the wing, end of their tails, and across the belly. They have broad wings that are fairly long and narrow, compared to other hawks.
Lemmings and voles provide most of the prey for Rough-legged Hawks. Voles, mice, ground squirrels, and other small mammals provide winter prey in states such as Connecticut. Nests are usually on a high cliff ledge and they lay 3-5 pale bluish-white eggs.
7. Northern Harrier
The Northern Harrier can be found in Connecticut all year but is more common in Winter.
This slim, longed-tailed Hawk can be seen gliding low over grassland or marshes. They are not often spotted.
- Length: 18.1-19.7 in (46-50 cm)
- Weight: 10.6-26.5 oz (300-750 g)
- Wingspan: 40.2-46.5 in (102-118 cm)
These hawks are slender with long broad wings and are between the size of a crow and goose. They often fly with the tips of their wings higher than their bodies in a v-shape. Females are brown and males are gray above and white below and they have a white rump patch.
Northern Harriers mostly eat small mammals and small birds. They nest on the ground in dense vegetation such as reeds, willows, or brushtails. They lay 4-5 dull white eggs
8. Northern Goshawk
The Northern Goshawk is in Connecticut in winter.
They live in large forests so are hard to find, especially as they are very secretive and can be aggressive if you get too close to a nest.
They are the bigger and fiercer relative of the Sharp-shinned and Cooper’s Hawks. These hawks are between the size of a crow and a goose. They are mostly gray with short, broad wings and a long tail. They have a white stripe over the eye and yellow eyes.
- Length: 20.9-25.2 in (53-64 cm)
- Weight: 22.3-48.1 oz (631-1364 g)
- Wingspan: 40.5-46.1 in (103-117 cm)
Goshawks live in large tracks of mostly coniferous or mixed forests. They watch for prey on high perches and mostly eat medium-sized birds and small mammals.
Northern Goshawks prepare up to eight nests and lay between 2-4 bluish-white eggs.
