10 Types of BIRDS Found on St. Croix! (COMMON)
Below you will find 10 COMMON BIRDS that live in St. Croix!
Believe it or not, over 200 species have been observed here, including many birds that only visit during migration. Because of the incredible variety, it would be impossible to list EVERY single type below.
So I did my best to come up with a list of the birds that are seen the MOST. Enjoy! 🙂
Common Birds of St. Croix:
#1. Yellow-crowned Night Heron
- Nyctanassa violacea
Identifying Characteristics:
- Gray body and yellow legs. Large red eyes.
- Black face with white cheeks and a thick black bill.
- As the name suggests, a yellowish-white crown with long white plumes.
These birds look for areas in St. Croix with shallow water to live in, such as wooded swamps, marshes, mangroves, and other coastal areas. Yellow-crowned Night-Herons can be found near both fresh and saltwater, and crustaceans (crabs and crayfish) make up most of their diet.
They are comfortable living near humans and will even nest in wooded neighborhoods or rooftops. Also, they are usually easy to see because Yellow-crowned Night-Herons eat and hunt at any time of day.
Upon being disturbed, you will hear a harsh “quawk,” which will probably be repeated a few times. Listen below:
#2. Great Egret
- Ardea alba
Identifying Characteristics:
- Large, white bird with long, black legs.
- S-curved neck and a dagger-like yellow bill. Look for a greenish area between their eyes and the base of the bill.
- While they fly, their neck is tucked in, and their long legs trail behind them.
Great Egrets are one of the most stunning birds in St. Croix.
These herons especially put on a show during breeding season when they grow long feathery plumes called aigrettes, which are held up during courtship displays.
These aigrettes are so beautiful that Great Egrets were almost hunted to extinction in the 19th century because these feathers made such nice decorations on ladies’ hats. The National Audubon Society was formed in response to help protect these birds from being slaughtered. To this day, the Great Egret serves as the organization’s symbol.
#3. Brown Pelican
- Pelecanus occidentalis
Identifying Characteristics:
- Brown skin on their giant throat patch.
- Dark gray bodies with a white neck and pale yellow head.
- Measures 3.5 – 5 feet in length (1 to 1.5 m) with a wingspan of 6.5 – 7.5 feet (2 to 2.3 m). The weight of adults can range from 4.4 to 11.0 lb (2 to 5 kg).
If you see a pelican in St. Croix while sitting on a beach, it is most likely a Brown Pelican. These large birds live strictly in saltwater habitats near the ocean’s coastline. Interestingly, they rarely venture into the open ocean, staying within 20 miles of the shore.
It’s a lot of fun watching Brown Pelicans hunting for fish! First, they fly high into the sky and then plunge aggressively headfirst into the water. These dives are meant to stun the surrounding fish, which then are scooped up with their enormous throat pouch and swallowed whole.
Check out the below video to learn more about their insane dives!
And lastly, they birds live a long time. The oldest Brown Pelican on record was 43 years of age!
#4. American Kestrel
- Falco sparverius
The American Kestrel is the smallest bird of prey in St. Croix.
But don’t let the tiny stature fool you because this raptor is an accomplished hunter. One of their favorite strategies to catch prey is to hover in the breeze from a relatively low height, looking for insects, invertebrates, small rodents, and birds.
Their diverse diet is one reason they can occupy ecological niches from central Alaska down to the southernmost tip of South America. But life can be tough when you’re the smallest falcon since they are sometimes eaten as prey by larger raptors and big snakes!
#5. Bananaquit
- Coereba flaveola
Identifying Characteristics:
- Adults range from 10-13 cm (4-5 in) long.
- Most adults have dark gray upperparts, a black crown, and a yellow chest, belly, and rump.
Bananaquits have something in common with many humans I know – a sweet tooth! Also known as “sugar birds” in St. Croix, this species is attracted to nectar feeders and bowls of sugar. They even enter homes looking for sweet treats.
Bananaquits are small, colorful, and known for adapting easily to human habitats. They like fruit and nectar, so they spend a lot of time near humans near flower gardens or fruit trees.
This species’ reliance on humans doesn’t stop with their diet. They often build their nests on human-made objects, including lampposts and garden trellises. Look for a globe-shaped tangle of sticks and leaves between 5 and 30 feet (1.5 to 9 m) off the ground.
#6. Magnificent Frigatebird
- Fregata magnificens
Identifying Characteristics:
- Long, narrow wings with a deeply forked tail.
- Males have a red throat patch, which is easily seen during the breeding season.
- Females have a white breast patch.
As the name implies, seeing these seabirds soaring effortlessly in the sky is quite “magnificent.” Using their forked tails to steer, they barely have to flap to stay afloat in the sky.
Due to the fact that their feathers are not waterproof like other seabirds, Magnificent Frigatebirds rarely land in the water and spend almost their entire lives flying. For food, they commonly steal fish from other birds or harass them until they regurgitate their meal, which they grab in midair! Their pirating ways have earned frigatebirds the nickname the “man-o-war bird.”
With Magnificent Frigatebirds, the “early bird” does not get the worm! Most individuals don’t take flight until later in the afternoon when thermals and winds are at their greatest. 🙂
#7. Zenaida Dove
- Zenaida aurita
Identifying Characteristics:
- Approximately 28–30 cm (11–12 in) in length.
- While flying, look for white plumage on the inner part of the wing.
Zenaida Doves look VERY similar to Mourning Doves and inhabit the same ecological niches. The main difference is that Zenaida Doves are smaller overall, slightly darker in color, and have a shorter, more rounded tail. Look for these birds in St. Croix in open, coastal habitats on the ground, feeding on seeds and grains.
A Zenaida Doves mournful song also sounds similar to a Mourning Dove but is faster in pace. You can listen below!
#8. Royal Tern
- Thalasseus maximus
Identifying Characteristics:
- Adults range from 45-50 cm (17.7-19.7 in) in length and have a 100-110 cm (39.4-43.3 in) wingspan.
- Breeding adults are gray below and white above.
- They have a black crest and a bright orange bill.
Royal Terns spend their lives in warm coastal waters. They’re frequently spotted in sheltered areas with shallow water, such as estuaries, bays, lagoons, and sandy beaches. They occasionally travel out to sea or inland, especially when feeding young, but stay within 80 km (50 mi) of the coast.
Breeding pairs of Royal Terns choose a site and build their nests together. The nests are simple scrapes in the earth. But, they have an unusual way of strengthening their nests. They defecate around the rim of the nest, and as it hardens, it reinforces the nest rim and helps keep it from flooding.
#9. Gray Kingbird
- Tyrannus dominicensis
Identifying Characteristics:
- Grayish bird with a whitish belly.
- Dark mask on the face that goes through the eye and cheek.
- Tail typically appears notched.
These birds are a lot of fun to watch in St. Croix!
Gray Kingbirds are bold and expert hunters. They are known to chase dragonflies and other insects for over a hundred yards in spectacular fashion, reminiscent of a fighter pilot!
Gray Kingbirds are fairly easy to find due to their raucous and memorable voice. Listen for a rolling pitirre call anytime throughout the year.
#10. Pearly-eyed Thrasher
- Margarops fuscatus
Identifying Characteristics:
- Mostly brown bird with brownish-white underparts.
- A bright, white eye.
Pearly-eyed Thrashers can be found in St. Croix in a variety of habitats, including wet and dry forests, open woodlands, scrub, gardens, and urban areas. As far as behavior, they act more like jays than thrashers, often bursting onto the scene noisily in groups, hoping to quickly take any available food.
Their calls and sounds vary from high-pitched whistles to brief chirps to harsh scolding.
