Back in early March I enjoyed a trip to coastal South Carolina, visiting locations near Pawleys Island such as Huntington Beach State Park, Myrtle Beach State Park and Brookgreen Gardens.

During my six-day stay in the South Carolina Low Country, I observed 95 species of birds, including several that should be making their spring return to our region any day now. I saw blue-gray gnatcatchers, yellow-throated warblers and a few shorebirds, including a greater yellowlegs. All of these birds usually migrate through Northeast Tennessee and Southwest Virginia in April and early May.

I also saw some coastal specialties that don’t usually come close to my landlocked home state of Tennessee, including anhinga, tricolored heron and brown pelican.

The brown pelican is the smallest of the world’s eight species of pelicans, which are grouped in the family Pelecanidae. Saying that a brown pelican is small, however, is a relative term. The brown pelican is about half the size of the related white pelican.

The brown pelican lives on both coasts, from around Seattle, Washington, and Cape Cod, Massachusetts, southward to the tropics. This pelican also lives along the Gulf Coast, as well as ranging south as far as the mouth of the Amazon River in South America.

According to the U.S. Fish & Wildlife Service’s website, there are two geographically and genetically distinct regional populations, or subspecies, of brown pelican that occur in North America. They are the California brown pelican, ranging from California to Chile, and the eastern brown pelican, which occurs along the Atlantic and Gulf coasts, as well as the Caribbean and the Central and South American coasts.

Pelicans have been documented living about 30 years in the wild, but the average age may be much less due to factors such as predation, disease and starvation. Many young pelicans, unskilled at catching fish, sadly do not reach adulthood.

DDT, which negatively affected breeding for birds such as bald eagle, osprey and peregrine falcon, also had a detrimental impact on the brown pelican. According to their website, in 1970, the U.S. Fish and Wildlife Service listed the brown pelican as endangered. The listing was possible through a law that had been passed before 1973’s Endangered Species Act. A recovery plan was published in 1983. In November 2009, the pelican was removed from the Endangered Species List, becoming another success story akin to that of the bald eagle.

Summer-Pelicans

Visitors to beaches along the Atlantic Coast have probably seen the impressive flight of brown pelicans in a single file formation of birds gliding only a few feet above the surf. The span of the wings can reach seven feet six inches. Seen near dusk, an observer could be forgiven a flight of fancy that allows these pelicans and their graceful flying formations to be compared to the long-extinct flying reptiles, the pterosaurs.

At a distance, the birds can readily be described as majestic and even graceful. On closer inspection, some different adjectives come into play to describe the brown pelican. At close quarters, a brown pelican is an ungainly, almost ugly bird. Pelicans have long necks and bills, and on land, they shuffle awkwardly. Young bird are drab brown and gray, often looking much more disheveled than adult birds.

According to the website All About Birds, the brown pelican feeds mostly on small fish such as menhaden, mullet, anchovies, herring, and sailfin mollies. These large birds may plunge from 65 feet above the surface of the water to capture fish in their famous throat pouch. In addition to fish, a pelican can take up to 2.6 gallons of water into its pouch with every dive. The water gets expelled, leaving behind the fish.

When not feeding, pelicans will rest on sandbars, pilings and rock jetties. These “loafing” spots are important places for pelicans to rest and recuperate after the rigors of diving and fishing for their fish meals.

The closest avian relatives of the pelicans are a couple of oddball birds known as the shoebill and hamerkop. The world’s other species of pelicans include Peruvian pelican, great white pelican, Australian pelican, American white pelican, pink-backed pelican, Dalmatian pelican and spot-billed pelican.

One state — Louisiana — has even made the brown pelican its official state bird. Most state birds are songbirds. The brown pelican is one of the exceptions, along with such birds as Minnesota’s common loon and the wild turkey, which has been adopted by Massachusetts.

On a handful of occasions, brown pelicans have made brief appearances in the region, usually generating a great deal of excitement among birders. White pelicans are also rare visitors, but they make slightly more stops in the region than their smaller relative. For instance, a white pelican spent a few days at Middlebrook Lake in Bristol around Thanksgiving in 2015. To increase your odds of observing a brown pelican in the wild, it will be much more productive to simply spend a few days along the coasts of Virginia, North Carolina, South Carolina, Georgia or Florida.

Red-shouldered hawk makes a fascinating, if somewhat shy, guest

People who feed the birds soon get to know the feisty personalities from the retiring wallflowers when it comes to the visitors to their yards. Northern mockingbirds, male ruby-throated hummingbirds and American robins are usually counted among the more boisterous birds.

Then there are the birds that shrink from interaction and hang back on the fringes, including wood thrushes, Eastern towhees and the large but shy pileated woodpecker. The latter example just goes to show that size doesn’t always equate with an extroverted personality when it comes to birds.

That’s certainly the case with a red-shouldered hawk that has taken up residence for the winter at my home. The hawk usually favors a stand of trees near the fish pond at my home when it visits the yard. The hawk made its initial appearances in December and then lingered into the new year. So far, the hawk has been a very shy guest. I’ve wanted to photograph the bird, but that’s difficult to do when it spooks and flies off the instant I step outside the door of my home. I’m not too disappointed because I know that raptors that are too comfortable around humans are at risk of running afoul of misinformed individuals who may regard all predatory birds as “bad.” The reality is that all hawks are valuable components of a healthy, working ecosystem with each species filling a certain niche.

According to a factsheet published by the New York State Department of Environmental Conservation, this raptor breeds in moist woodlands, riverine forests, the borders of swamps, open pine woods and similar habitats. Nesting almost always occurs near water, such as a swamp, river or pond.

The red-shouldered hawk is an ambush predator. This raptor usually selects a favorable perch and remains still while scanning for possible prey. The hawk will drop rapidly onto any prey that wanders carelessly within range. In the summer, prey items largely consist of reptiles and amphibians, including snakes and frogs, as well as some insects and crayfish. Most of these creatures are scarce during the colder months of the year, which prompts these hawks to adopt a diet that focuses on rodents and the occasional songbird. Other than the altercations with the resident crows, I haven’t observed any encounters between the hawk at my home and any other birds — with one exception.

On a recent morning, the hawk was on its usual perch — a branch of a large willow adjacent to the fish pond — when seven Canada geese, another rare visitor to my home, suffered some sort of fright and took flight. The noisy geese flew directly over the willow, which spooked the raptor into taking flight in the opposite direction of the departing geese.

The red-shouldered hawk produces a distinctive, piercing whistle that reminds me of the shrill call of a killdeer. The hawk at my house has been silent so far, perhaps not wishing to draw attention. The few times the local crows have noticed the hawk’s presence, they’ve flocked together to mob the unfortunate hawk. It’s also not the right time of year. During courtship and the subsequent nesting period, these hawks are vocal. At other times of the year, they are rarely heard. It’s also possible to mistakenly think you have heard one of these large hawks. Blue jays have apparently learned to imitate the “kee-yar” call of this hawk, often working a flawless rendition of the whistled notes of this large raptor.

In contrast to the related red-tailed hawk, the red-shouldered hawk soars less and prefers to perch hidden in the cover of trees. This hawk’s name comes from the reddish-brown shoulder patches in the bird’s wings. Adults show a tail marked with vivid bands of black and white that is quite distinctive.

The red-shouldered hawk belongs to the same genus of raptors as its larger relative, the red-tailed hawk. The genus, buteo, includes about two dozen large raptors that are often dominant avian predators in their respective habitats. The red-shouldered hawk is known by the scientific name Buteo lineatus.

The red-shouldered hawk is less common in the region than some of the other raptors. This hawk’s stronghold is in Florida and other southern states like South Carolina and Georgia. I’ve seen many of these hawks on visits to both the Sunshine State and Palmetto State.

Some of the buteo species have adapted to life on islands, including the Galapagos hawk and the Hawaiian hawk. Some of these hawks have quite descriptive names, including the white-throated hawk, gray-lined hawk, zone-tailed hawk and short-tailed hawk. Outside the United States, raptors in the buteo genus are often known as buzzards. When the first European colonists came to the New World, they applied the term buzzard to both native vultures, as well as the large raptors like Swainson’s hawk and broad-winged hawk that reminded them of the ones back in Europe.

It’s been nice hosting this beautiful raptor, although the crows might disagree with me. A neighbor who lives close to me has had red-shouldered hawks spend the summer months on her property, so I’m hopeful that my visitor might even like the surroundings well enough to become a full-time resident.
