Black-throated Green Warbler


An abundant breeder of the northeastern coniferous forests, the Black-throated Green Warbler is easy to recognize by sight and sound. Its dark black bib and bright yellow face are unique amongst Eastern birds, and its persistent song of "zoo-zee, zoo-zoo-zee" is easy to remember.

We saw this guy in Rocky Branch State Park near Tuscaloosa Alabama. It may have been because of early migration since these specific birds aren't seen in Alabama unless its during the fall or spring migration. So we were pretty luck to see him!

The male Black-throated Green Warbler sings persistently during the breeding season. One individual was observed singing 466 songs in one hour.

Red-eyed Vireo


One of the most common birds of the Eastern forests, the Red-eyed Vireo is heard far more than it is seen. It sings continuously from the forest canopy from dawn to dusk. The vireo's song is a series of phrases interspaced with short pauses, like the song of an American Robin broken into pieces.

Although animal food makes up 85 percent of its summer diet, the Red-eyed Vireo may be completely frugivorous (fruit-eating) during the winter. The Red-eyed Vireo is a common host to the Brown-headed Cowbird, which lays its eggs in the vireo's nest. Red-eyed Vireos living year-round in South America may be a separate species.

Black Vulture


With sooty black plumage, a bare black head, and neat white stars under the wingtips, Black Vultures are almost dapper. Whereas Turkey Vultures are lanky birds with teetering flight, Black Vultures are compact birds with broad wings, short tails, and powerful wingbeats. The two species often associate: the Black Vulture makes up for its poor sense of smell by following Turkey Vultures to carcasses. Highly social birds with fierce family loyalty, Black Vultures share food with relatives, feeding young for months after they’ve fledged.

In the U.S., Black Vultures are outnumbered by their red-headed relatives, Turkey Vultures, but they have a huge range and are the most numerous vulture in the Western Hemisphere. One-on-one at a carcass, Black Vultures lose out to the slightly larger Turkey Vulture. But flocks of Black Vultures can quickly take over a carcass and drive the more solitary Turkey Vultures away. Black Vultures lack a voice box and so their vocal abilities are limited to making raspy hisses and grunts. Although Black Vultures and their relatives live only in North and South America, the oldest fossils from this group—at least 34 million years old—were found in Europe.

Mississippi Kite


July 19th I was walking to my car to go to work.  It was about 7:20am and I saw a Mississippi Kite soaring above me and swooping down in a dive bomb position and then darting back up to a safe altitude.  It was magical and I ran into the apartment to get my camera.  I snapped 4 blurry photos.  The next day was the weekend and I woke up early to made a little trek across the parking lot to the area I've seen the bird before.  I was amazed to find SEVEN mississippi kites all in the same area!  They were darting and dancing all over the open field!  It was one of my favorite birding moments and Susanne was unable to wake up to see it with me :(

A graceful, long-winged raptor, the Mississippi Kite is found in scattered localities across the southern and central United States. Mississippi Kites have been known migrate south in huge flocks and hundreds and hundreds of Kites have been witnessed flocking across Texas.

Great Crested Flycatcher


A treetop hunter of deciduous forests and suburban areas, the Great Crested Flycatcher is easier to hear than to see. The only eastern flycatcher that nests in cavities, it often includes snakeskin in the nest lining.

The Great Crested Flycatcher is a bird of the treetops. It spends very little time on the ground, and does not hop or walk. It prefers to fly from place to place on the ground rather than walk.

Osprey


Unique among North American raptors for its diet of live fish and ability to dive into water to catch them, Ospreys are common sights soaring over shorelines, patrolling waterways, and standing on their huge stick nests, white heads gleaming. These large, rangy hawks do well around humans and have rebounded in numbers following the ban on the pesticide DDT. Hunting Ospreys are a picture of concentration, diving with feet outstretched and yellow eyes sighting straight along their talons.

I witnessed an osprey in Tuscaloosa but this photograph was taken two years ago in Tampa Bay Florida.

An Osprey may log more than 160,000 migration miles during its 15-to-20-year lifetime. Scientists track Ospreys by strapping lightweight satellite transmitters to the birds’ backs. The devices pinpoint an Osprey's location to within a few hundred yards and last for 2-3 years. During 13 days in 2008, one Osprey flew 2,700 miles—from Martha's Vineyard, Massachusetts, to French Guiana, South America. Ospreys are unusual among hawks in possessing a reversible outer toe that allows them to grasp with two toes in front and two behind. Barbed pads on the soles of the birds' feet help them grip slippery fish. When flying with prey, an Osprey lines up its catch head first for less wind resistance. Ospreys are excellent anglers. Over several studies, Ospreys caught fish on at least 1 in every 4 dives, with success rates sometimes as high as 70 percent. The average time they spent hunting before making a catch was about 12 minutes—something to think about next time you throw your line in the water. The oldest known Osprey was 25 years, 2 months old.

Indigo Bunting


The all-blue male Indigo Bunting sings with cheerful gusto and looks like a scrap of sky with wings. Sometimes nicknamed "blue canaries," these brilliantly colored yet common and widespread birds whistle their bouncy songs through the late spring and summer all over eastern North America. Look for Indigo Buntings in weedy fields and shrubby areas near trees, singing from dawn to dusk atop the tallest perch in sight or foraging for seeds and insects in low vegetation.

Indigo Buntings migrate at night, using the stars for guidance. Researchers demonstrated this process in the late 1960s by studying captive Indigo Buntings in a planetarium and then under the natural night sky. The birds possess an internal clock that enables them to continually adjust their angle of orientation to a star—even as that star moves through the night sky. Like all other blue birds, Indigo Buntings lack blue pigment. Their jewel-like color comes instead from microscopic structures in the feathers that refract and reflect blue light, much like the airborne particles that cause the sky to look blue.

Red-headed Woodpecker


The gorgeous Red-headed Woodpecker is so boldly patterned it’s been called a “flying checkerboard,” with an entirely crimson head, a snow-white body, and half white, half inky black wings. These birds don’t act quite like most other woodpeckers: they’re adept at catching insects in the air, and they eat lots of acorns and beech nuts, often hiding away extra food in tree crevices for later. This magnificent species has declined severely in the past half-century because of habitat loss and changes to its food supply.

The Red-headed Woodpecker is one of only four North American woodpeckers known to store food, and it is the only one known to cover the stored food with wood or bark. It hides insects and seeds in cracks in wood, under bark, in fenceposts, and under roof shingles. Grasshoppers are regularly stored alive, but wedged into crevices so tightly that they cannot escape. Red-headed Woodpeckers are fierce defenders of their territory. They may remove the eggs of other species from nests and nest boxes, destroy other birds’ nests, and even enter duck nest boxes and puncture the duck eggs. The striking Red-headed Woodpecker has earned a place in human culture. Cherokee Indians used the species as a war symbol, and it makes an appearance in Longfellow’s epic poem The Song of Hiawatha, telling how a grateful Hiawatha gave the bird its red head in thanks for its service. The Red-headed Woodpecker was the “spark bird” (the bird that starts a person’s interest in birds) of legendary ornithologist Alexander Wilson in the 1700s.

Prothonotary Warbler


A brilliant yellow-orange bird of southeastern wooded swamps, the Prothonotary Warbler is a striking sight.

The name "Prothonotary" refers to clerks in the Roman Catholic church, whose robes were bright yellow.

Eastern Towhee


A strikingly marked, oversized sparrow of the East, feathered in bold black and warm reddish-browns – if you can get a clear look at it. Eastern Towhees are birds of the undergrowth, where their rummaging makes far more noise than you would expect for their size. Their chewink calls let you know how common they are, but many of your sightings end up mere glimpses through tangles of little stems.

Eastern Towhees are common victims of the parasitic Brown-headed Cowbird. Female cowbirds lay eggs in towhee nests, then leave the birds to raise their cowbird young. In some areas cowbirds lay eggs in more than half of all towhee nests. Towhees, unlike some other birds, show no ability to recognize or remove the imposter’s eggs. Female cowbirds typically take out a towhee egg when laying their own, making the swap still harder to notice.

Broad-winged Hawk


One of the greatest spectacles of migration is a swirling flock of Broad-winged Hawks on their way to South America. Also known as “kettles,” flocks can contain thousands of circling birds that evoke a vast cauldron being stirred with an invisible spoon. A small, stocky raptor with black-and-white bands on the tail, the Broad-winged Hawk is a bird of the forest interior and can be hard to see during the nesting season. Its call is a piercing, two-parted whistle. I saw this bird early one morning on July 14th. I was by myself, Susanne was away for the weekend. I kept hearing a sharp piercing call and then I was a this broad-winged hawk being chased out of the forest by three small birds. It perched up on this dead branch and just sat there and sat there. After 45 minutes of observing this scared predator and taking over 350 pictures of it, I decided to go my own way and leave this bird alone to conquer its fears.

Scientists used satellite transmitters to track four Broad-winged Hawks as they migrated south in the fall. The hawks migrated an average of 4,350 miles to northern South America, traveling 69 miles each day. Once on their wintering grounds the hawks did not move around much, staying on average within a 1-square-mile area. Late Pleistocene fossils of Broad-winged Hawks, up to 400,000 years old, have been unearthed in Florida, Iowa, Illinois, Virginia, and Puerto Rico. It's hard to believe they travel so far year after year, but they do. So in order to observe this raptor of the sky, it has to be during summer!

Wood Duck


The Wood Duck is one of the most stunningly pretty of all waterfowl. Males are iridescent chestnut and green, with ornate patterns on nearly every feather; the elegant females have a distinctive profile and delicate white pattern around the eye. These birds live in wooded swamps, where they nest in holes in trees or in nest boxes put up around lake margins. They are one of the few duck species equipped with strong claws that can grip bark and perch on branches.

This wood duck doesn't look like the traditional flamboyant wood ducks but that is because this is a non-breeding male wood duck. If it was a breeding male wood duck, it would have the picturesque head piece.

Dad is responsible for this picture. We were going into Chick-fil-a when Dad pointed out this duck near the parking lot. I had my heart set on a milk shake but I was able to fight off that craving long enough to snap a few pics of this bird.

The Wood Duck nests in trees near water, sometimes directly over water, but other times up to 2 km (1.2 mi) away. After hatching, the ducklings jump down from the nest tree and make their way to water. The mother calls them to her, but does not help them in any way. The ducklings may jump from heights of up to 89 m (290 ft) without injury. The Wood Duck is a popular game bird, and is second only to the Mallard in numbers shot each year in the United States. Wood Ducks pair up in January, and most birds arriving at the breeding grounds in the spring are already paired. The Wood Duck is the only North American duck that regularly produces two broods in one year.

Gull-billed Tern


A medium-sized tern with broader wings and a thicker bill than most other terns, the Gull-billed Tern is found along the Atlantic and Gulf coasts of the United States and very southern California.

Unlike most terns, the Gull-billed Tern has a broad diet and does not depend on fish. Instead it commonly feeds on insects, small crabs, and other prey snatched from the ground, air, or even bushes. It is also known to eat small chicks of other tern species.

Wild Turkey

Black Skimmer


The remarkable bill of the Black Skimmer sets it apart from all other American birds. The large red and black bill is knife-thin and the lower mandible is longer than the upper. The bird drags the lower bill through the water as it flies along, hoping to catch small fish.

The Black Skimmer is the only American representative of the skimmer family. The other two, rather similar, species are the African Skimmer and the Indian Skimmer. All use the same unusual feeding method. Although the Black Skimmer is active throughout the day, it is largely crepuscular (active in the dawn and dusk) and even nocturnal. Its use of touch to catch fish lets it be successful in low light or darkness. Possibly the best description of the Black Skimmer's bounding, head-down foraging style came from R. C. Murphy in 1936. He said they look like “unworldly… aerial beagles hot on the scent of aerial rabbits.”

Wood Stork


A large, white, bald-headed wading bird of the southeastern swamps, the Wood Stork is the only stork breeding in the United States. Its late winter breeding season is timed to the Florida dry season when its fish prey become concentrated in shrinking pools.

Royal Tern




A pretty royal tern photographed in Charleston South Carolina

Young Royal Terns leave the nest scrape within one day after hatching and congregate together in a group known as a crèche. Eventually all of the chicks in a colony come to the crèche, which can have thousands of chicks ranging in age from two to 35 days old. A pair of Royal Terns will feed only their own chick, and manage to find it in the crowd, probably by recognizing its call.

Brown Pelican



The Brown Pelican is a comically elegant bird with an oversized bill, sinuous neck, and big, dark body. Squadrons glide above the surf along southern and western coasts, rising and falling in a graceful echo of the waves. They feed by plunge-diving from high up, using the force of impact to stun small fish before scooping them up. They are fairly common today—an excellent example of a species’ recovery from pesticide pollution that once placed them at the brink of extinction.

This photograph was taken in Tampa Bay in 2012. but Susanne and I saw numerous brown pelicans in Charleston but we were able to capture the best photo that reflected this birds true beauty.

While the Brown Pelican is draining the water from its bill after a dive, gulls often try to steal the fish right out of its pouch—sometimes while perching on the pelican's head. Pelicans themselves are not above stealing fish, as they follow fishing boats and hang around piers for handouts. Pelicans incubate their eggs with the skin of their feet, essentially standing on the eggs to keep them warm. In the mid-twentieth century the pesticide DDT caused pelicans to lay thinner eggs that cracked under the weight of incubating parents. After nearly disappearing from North America in the 1960s and 1970s, Brown Pelicans made a full comeback thanks to pesticide regulations. During a dive, the Brown Pelican tucks its head and rotates its body to the left. This maneuver is probably to cushion the trachea and esophagus—which are found on the right side of the neck—from the impact.

Fish Crow


Not everyone realizes it, but there are two kinds of crows across much of the eastern United States. Looking almost identical to the ubiquitous American Crow, Fish Crows are tough to identify until you learn their nasal calls. Look for them around bodies of water, usually in flocks and sometimes with American Crows. They are supreme generalists, eating just about anything they can find. Fish Crows have expanded their range inland and northward along major river systems in recent decades.

Photographed in the marshes of Charleston.

When Fish Crows find a good source of food, they may cache the surplus for later. These hiding places can be in grass, in clumps of Spanish moss, or in crevices in tree bark. Nesting adults may use these caches when feeding their young. Fish Crows build a new nest for each breeding attempt. The nests are well-made, and one small area may have existing nests from up to four different years.

Rock Dove (Rock Pigeon)


A common sight in cities around the world, Rock Doves crowd streets and public squares, living on discarded food and offerings of birdseed. In addition to the typical blue-gray bird with two dark wingbars, you'll often see flocks with plain, spotted, pale, or rusty-red birds in them. Introduced to North America from Europe in the early 1600s, city pigeons nest on buildings and window ledges. In the countryside they also nest on barns and grain towers, under bridges, and on natural cliffs.

Pigeons can find their way home, even if released from a distant location blindfolded. They can navigate 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. Mesopotamian cuneiform tablets and Egyptian hieroglyphics suggest that pigeons were domesticated more than 5,000 years ago. The birds have such a long history with humans that it's impossible to tell where the species' original range was. Rock Doves carried messages for the U.S. Army Signal Corps during World War I and II, saving lives and providing vital strategic information.

American Oystercatcher


A large, boldly patterned bird, the American Oystercatcher is conspicuous along ocean shores and salt marshes. True to its name, it is specialized in feeding on bivalves (oysters, clams, and mussels) and uses its brightly colored bill to get at them.

This was photographed in Charleston Harbor. I didn't know what I was photographing till I looked at the picture.

Ring-billed Gull


Familiar acrobats of the air, Ring-billed Gulls nimbly pluck tossed tidbits from on high. Comfortable around humans, they frequent parking lots, garbage dumps, beaches, and fields, sometimes by the hundreds. These are the gulls you're most likely to see far away from coastal areas—in fact, most Ring-billed Gulls nest in the interior of the continent, near freshwater. A black band encircling the yellow bill helps distinguish adults from other gulls—but look closely, as some other species have black or red spots on the bill.

This male gull was photographed on the shores of Charleston Bay. It doesn't have the yellow bill signifying it is a first summer or non-breeding adult male.

Many, if not most, Ring-billed Gulls return to breed at the colony where they hatched. Once they have bred, they are likely to return to the same breeding spot each year, often nesting within a few meters of the last year's nest site. Many individuals return to the same wintering sites each winter too. Although it is considered a typical large white-headed gull, the Ring-billed Gull has been known to hybridize only with smaller, black-headed species, such as Franklin's, Black-headed, and Laughing gulls. Migrating Ring-billed Gulls apparently use a built-in compass to navigate. When tested at only two days of age, chicks showed a preference for magnetic bearings that would take them in the appropriate direction for their fall migration. The gulls also rely on landmarks and high-altitude winds to provide directional cues.

Boat-tailed Grackle


When you smell saltwater on the East Coast, it’s time to look out for Boat-tailed Grackles. The glossy blue-black males are hard to miss as they haul their ridiculously long tails around or display from marsh grasses or telephone wires. The rich, dark-brown females are half the size of males and look almost like a different species. Boat-tailed Grackles take advantage of human activity along our increasingly developed coast, scavenging trash and hanging out in busy urban areas away from predators. This guy was photographed in Charleston on July 5th. Susanne and I both thought the female boat-tailed grackle nearby was a completely different species.

The Boat-tailed Grackle has an odd mating system, called “harem defense polygyny,” that has much in common with deer and other big game. Females cluster their nests in a small area safe from predators, and males compete to see which one gets to defend and mate with the entire colony. But it’s not as simple as it may seem: though a colony’s dominant male mates far more often with the females, DNA fingerprinting shows that only about a quarter of the young are actually his. The remainder are fathered by males who the females mate with while away from the colony. The oldest Boat-tailed Grackle on record was nearly 14 years old when it was caught and released by a South Carolina bird bander in 2003.

Least Tern


The smallest of American Terns, the Least Tern is found nesting on sandy beaches along the southern coasts of the United States and up the major river systems far into the interior of the continent.

The Least Tern prefers sandy beaches for nesting, but it will use a flat gravel roof of a building. On sunny days the hot tar showing through the gravel can burn the feet of chicks or become stuck in their down.

Least Tern Range Map


Laughing Gull


Swirling over beaches with strident calls and a distinctive, crisp black head, Laughing Gulls provide sights and sounds evocative of summer on the East Coast. You’ll run across this handsome gull in large numbers at beaches, docks, and parking lots, where they wait for handouts or fill the air with their raucous calls. Laughing Gulls are summer visitors to the Northeast and year-round sights on the coasts of the Southeast and the Gulf of Mexico.

We were waiting in line for a table at Hometeam BBQ on Sullivan's Island when this common shore bird landed on the telephone pole in front.

Nest colonies in the northeastern United States were nearly eliminated by egg and plume hunters in the late 19th century. Populations have increased over the last century, following protection. The adult Laughing Gull removes the eggshells from the nest after the eggs hatch. If the shells are not removed, a piece can become lodged on top of the slightly smaller unhatched third egg and prevent it from hatching.
