The Brown-headed Cowbird is a stocky blackbird with a fascinating approach to raising its young. Females forgo building nests and instead put all their energy into producing eggs, sometimes more than three dozen a summer. These they lay in the nests of other birds, abandoning their young to foster parents, usually at the expense of at least some of the host’s own chicks. Once confined to the open grasslands of middle North America, cowbirds have surged in numbers and range as humans built towns and cleared woods.Male Brown-headed Cowbirds have glossy black plumage and a rich brown head that often looks black in poor lighting or at distance. Female Brown-headed Cowbirds are plain brown birds, lightest on the head and underparts, with fine streaking on the belly and a dark eye.Brown-headed Cowbirds feed on the ground in mixed-species groups of blackbirds and starlings. Males gather on lawns to strut and display for mates. Females prowl woodlands and edges in search of nests. Brown-headed Cowbirds are noisy, making a multitude of clicks, whistles and chatter-like calls in addition to a flowing, gurgling song.You’ll find Brown-headed Cowbirds in many open habitats, such as fields, pastures, meadows, forest edges, and lawns. When not displaying or feeding on the ground, they often perch high on prominent tree branches.Overall,cowbirds are cool

Sandpipers
Sandpipers are a large family Scolopacidae, of waders or shorebirds.They include many species called sandpipers, as well as those called by names such as curlew and snipe. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food.Sandpipers have long bodies and legs, and narrow wings. Most species have a narrow bill, but otherwise the form and length are quite variable. They are small to medium-sized birds, measuring 12 to 66 cm (4.7–26.0 in) cm in length. The bills are sensitive, allowing the birds to feel the mud and sand as they probe for food. They generally have dull plumage, with cryptic brown, grey, or streaked patterns, although some display brighter colors during the breeding season.[1]
Most species nest in open areas, and defend their territories with aerial displays. The nest itself is a simple scrape in the ground, in which the bird typically lays three or four eggs. The young of most species are precocial.[1]There are broadly four feeding styles employed by the sandpipers, although many species are flexible and may use more than one style. The first is pecking with occasional probing, usually done by species in drier habitats that do not have soft soils or mud. The second, and most frequent, method employed is probing soft soils, muds and sands for prey. The third, used by Tringa shanks, involves running in shallow water with the bill under the water chasing fish, a method that uses sight as well as tactile senses. The final method, employed by the phalaropes and some Calidris sandpipers, involves pecking at the water for small prey.Sandpipers are cool.

Brown booby
The brown booby is a large seabird of the booby family, Sulidae. The female booby reaches about 80 centimetres (31 in) in length, its wingspan measures up to 150 cm (4.9 ft), and they can weigh up to 1,300 g (2.9 lb). The male booby reaches about 75 centimetres (30 in) in length, its wingspan measures up to 140 cm (4.6 ft), and they can weigh up to 1,000 g (2.2 lb).The booby's head and upper body (back) is covered in dark brown or black, with the remainder (belly) being a contrasting white. The juvenile form is gray-brown with darkening on the head, wings and tail. While these birds are typically silent, bird watchers have reported occasional sounds similar to grunting or quacking. Their beaks are quite sharp and contain many jagged edges. They have short wings and long, tapered tails.This species breeds on islands and coasts in the pan tropical areas of the Atlantic and Pacific oceans. They frequent the breeding grounds of the islands in the Gulf of Mexico and the Caribbean Sea. This bird nests in large colonies, laying two chalky blue eggs on the ground in a mound of broken shells and vegetation. It winters at sea over a wider area.Brown booby pairs may remain together over several seasons. They perform elaborate greeting rituals, and are also spectacular divers, plunging into the ocean at high speed. They mainly eat small fish or squid which gather in groups near the surface and may catch leaping fish while skimming the surface. Although they are powerful and agile fliers, they are particularly clumsy in takeoffs and landings; they use strong winds and high perches to assist their takeoffs.I like brown booby birds.

Woodpeckers
The woodpeckers are part of the Picidae family, a group of near-passerine birds that also consist of piculets, wrynecks, and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand,Madagascar, and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known to live in treeless areas, such as rocky hillsides and deserts.The Picidae are just one of eight living families in the order Piciformes. Other members of Piciformes, such as thejacamars, puffbirds, barbets, toucans, and honeyguides, have traditionally been thought to be closely related to the woodpeckers, piculets, wry necks.There are about 200 species and about 30 genera in this family. Many species are threatened or endangered due to loss of habitat or habitat fragmentation. Two species of woodpeckers, the ivory-billed woodpecker and the imperial woodpecker, have been considered extinct for about 30 years.Woodpeckers, piculets and wrynecks all possess zygodactyl feet. Zygodactyl feet consist of four toes, the first (hallux) and the fourth facing backward and the second and third facing forward. This foot arrangement is good for grasping the limbs and trunks of trees. Members of this family can walk vertically up a tree trunk, which is beneficial for activities such as foraging for food or nest excavation. In addition to their strong claws and feet, woodpeckers have short strong legs. This is typical of birds that regularly forage on trunks. The tails of all woodpeckers except the piculets and wry necks are stiffened, and when the bird perches on vertical surfaces, the tail and feet work together to support it.Overall, the woodpeckers are arboreal birds of wooded habitats.

Cranes
There are fifteen species of crane in four genera. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Cranes live on all continents except Antarctica and South America.They are opportunistic feeders that change their diet according to the season and their own nutrient requirements. They eat a range of items from suitably sized small rodents, fish, amphibians, and insects to grain, berries, and plants.Cranes construct platform nests in shallow water, and typically lay two eggs at a time. Both parents help to rear the young, which remain with them until the next breeding season.Some species and populations of cranes migrate over long distances; others do not migrate at all. Cranes are solitary during the breeding season, occurring in pairs, but during the non-breeding season they are gregarious, forming large flocks where their numbers are sufficient.The cranes are large to very large birds, including the world's tallest flying bird.They range in size from the demoiselle crane, which measures 90 cm (35 in) in length, to the sarus crane, which can be up to 176 cm (69 in), although the heaviest is the red-crowned crane, which can weigh 12 kg (26 lb) prior to migrating. They are long-legged and long-necked birds with streamlined bodies and large rounded wings. The males and females do not vary in external appearance, but on average males tend to be slightly larger than females.Cranes are territorial and generally seasonal breeders.Cranes are cool.
Crows
Crows gather in large communal roosts numbering between 200 and tens of thousands of individuals during non breeding months, particularly in the winter. These gatherings tend to happen near large food sources such as garbage dumps and shopping centers.Countless incidents are recorded of crows at play.As a group, crows show remarkable examples of intelligence.One species, the New Caledonian crow, has also been intensively studied recently because of its ability to manufacture and use tools in the day-to-day search for food. On 5 October 2007, researchers from the University of Oxford presented data acquired by mounting tiny video cameras on the tails of New Caledonian crows. They pluck, smooth, and bend twigs and grass stems to procure a variety of foodstuffs.Crows are omnivorous, and their diet is very diverse. They will eat almost anything, including other birds, fruits, nuts, mollusks, earthworms, seeds, frogs, eggs, nestlings, mice, and carrion. The origin of placing scarecrows in grain fields resulted from the crow’s incessant damaging and scavenging, although crows assist farmers by eating insects otherwise attracted to their crops.Did you know that crows give funeral services to other crows.Yes,when one crow dies a bunch of crows will sit in a nearby tree and look at the dead crow. That is pretty cool.

Bee-eaters
The bee-eaters are a group of near-passerine birds in the family Meropidae. Most species are found in Africa and Asia but others occur in southern Europe, Australia, and New Guinea. They are characterised by richly coloured plumage, slender bodies, and usually elongated central tail feathers. All have long downturned bills and pointed wings, which give them a swallow-like appearance when seen from afar. There are 26 different species of bee-eaters.As the name suggests, bee-eaters predominantly eat flying insects, especially bees and wasps, which are caught in the air by sallies from an open perch.[1] While they pursue any type of flying insect, honey bees predominate in their diet.Before eating its meal, a bee-eater removes the stinger by repeatedly hitting and rubbing the insect on a hard surface. During this process, pressure is applied to the insect thereby extracting most of the venom.[1] Notably, the birds only catch prey that are on the wing and ignore flying insects once they land.
Bee-eaters are gregarious. They form colonies by nesting in burrows tunnelled into the side of sandy banks, such as those that have collapsed on the edges of rivers. Their eggs are white and they generally produce 2–9 eggs per clutch (depending on species). As they live in colonies, large numbers of these holes are often seen together, white streaks from their accumulated droppings accentuating the entrances to the nests. Most of the species in the family are monogamous, and both parents care for the young, sometimes with the assistance of other birds in the colony, a behavior considered unusual for birds.I like bee-eaters

Grass bird
The Little grass bird is a small, unobtrusive dark brown-grey bird. It has a grey-brown head with a pale eyebrow, chin and throat and the crown and cheeks are streaked dark grey. The upper body is brown-grey, streaked dark grey, the dark wing feathers are edged with white and the paler grey under body is also streaked. Young birds are more uniform grey with finer streaking.The grass bird is found across eastern Australia and Tasmania, inland to central Australia and in south-western Australia. It is also found in New Guinea.The grass bird is found in swamps and marshes, preferring thick reed beds, and will occur in temporary wetlands after rains.The little grass bird eats insects and other small arthropods, usually remaining in the dense cover of grasses and swamp vegetation.The grass bird builds a deep cup nest of reeds and coarse grasses, lined with feathers, hidden in thick reedy vegetation.The grass bird is small but very cute.
Roseate Spoonbills
The roseate spoonbill is a gregarious wading bird of the ibis and spoonbill family.It is a resident breeder in South America mostly east of the Andes, and in coastal regions of the Caribbean, Central America, Mexico, the Gulf Coast of the United States [2][3] and on central Florida's Atlantic coast.The roseate spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb).Like the American flamingo, their pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin. Another carotenoid, astaxanthin, can also be found deposited in flight and body feathers.[9] The colors can range from pale pink to bright magenta, depending on age and location. Unlike herons, spoonbills fly with their necks outstretched. They alternate groups of stiff, shallow wing beats with glides.This species feeds in shallow fresh or coastal waters by swinging its bill from side to side as it steadily walks through the water, often in groups. The spoon-shaped bill allows it to sift easily through mud. It feeds on crustaceans, aquatic insects, frogs, newts and very small fish ignored by larger waders. In the United States, a popular place to observe roseate spoonbills is "Ding" Darling National Wildlife Refuge in Florida. Roseate spoonbills must compete for food with snowy egrets, great egrets, tricolored herons and American white pelicans.Nestlings are sometimes killed by turkey vultures, bald eagles, raccoons and fire ants.Roseate spoonbills are pretty birds.
Turkeys
Wild turkeys, with their distinctive feathers and gobbling call, were Benjamin Franklin's choice for the national bird of the United States.
Females lay 4 to 17 eggs, and feed their chicks after they hatch—but only for a few days. Young turkeys quickly learn to fend for themselves as part of mother/child flocks that can include dozens of animals. Males take no role in the care of young turkeys.
Domestic turkeys have white-tipped tails because they are the descendants of a Mexican subspecies that was taken to Europe for domestication in the early 16th century. The feature distinguishes them from most modern wild turkeys, though captive diet, lifestyle, and breeding have caused other physical discrepancies.Turkeys are very cool.

Doves
Mourning doves are graceful, slender-tailed, small-headed dove that are common across the continent. Mourning Doves perch on telephone wires and forage for seeds on the ground; their flight is fast and bullet straight. Their soft, drawn-out calls sound like laments. When taking off, their wings make a sharp whistling or whinnying. Plump-bodied and long-tailed, with short legs, small bill, and a head that looks particularly small in comparison to the body. The long, pointed tail is unique among North American doves.Plump-bodied and long-tailed, with short legs, small bill, and a head that looks particularly small in comparison to the body. The long, pointed tail is unique among North American doves.You can see Mourning Doves nearly anywhere except the deep woods. Look for them in fields or patches of bare ground, or on overhead perches like telephone wires.Mourning Doves are the most frequently hunted species in North America.

Cardinals
Cardinals, in the family Cardinalidae, are passerine birds found in North and South America. They are also known as cardinal-grosbeaks and cardinal-buntings.They are robust, seed-eating birds with strong bills. The family ranges in size from the 12-cm (4.7-in), 11.5-g (0.40-oz) and uporange-breasted bunting to the 25-cm (9.8-in), 85-g (2.99-oz) black-headed saltator. They are typically associated with openwoodland. The northern cardinal type species was named by colonists for the male's red crest.
Northern cardinals are numerous across the eastern United States from Maine to Texas and in Canada in the provinces of Ontario, Quebec, New Brunswick andNova Scotia.The northern cardinal is a territorial song bird. The male sings in a loud, clear whistle from the top of a tree or another high location to defend his territory. He will chase off other males entering his territory. He may mistake his image on various reflective surfaces as an invading male, and will fight his reflection relentlessly. The northern cardinal learns its songs, and as a result the songs vary regionally. Mated pairs often travel together.Northern cardinals are preyed upon by a wide variety of predators native to North America, including falcons, all Accipiterhawks, shrikes, and several owls, including long-eared owls, and eastern screech owls. Predators of chicks and eggs include milk snakes, coluber constrictors, blue jays, eastern gray squirrels, fox squirrels, eastern chipmunks,[9] and domestic cats.I like cardinals.
