Double-crested Cormorant

General:

The Double-crested Cormorant is the most numerous and widespread North American cormorant. It can occur in large numbers inland as well as on the coast.

In upstate New York this cormorant has increased in numbers. Twenty years ago it was an infrequent site, nowDouble-crested Cormorant – Phalacrocorax auritus large colonies on the Great Lakes and large inland lakes has led to the concern about their predation on sport fish.Double-crested Cormorant

When on the water their bodies, as shown in the picture, are almost entirely submerged. When out of the water and perching they often spread their wings to dry.

The Double-crested Cormorant makes a bulky nest of sticks and other materials. In breeding colonies where the nests are placed on the ground, young cormorants leave their nests and congregate into groups.

The Double-crested cormorant egg is chalky blue. The chicks will hatch in 25-29 days and will fledge in 35-42 days

Identification:

Double-crested Cormorant – Adult Description: They are large, dark bodied water birds – approximately 30″ to 35″. They have a long body and long neck.

Yellow warbler

Yellow warbler

General:

The Yellow Warbler, Dendroica petechia, is a New World warbler. It is the most widespread Dendroica warbler, breeding in almost the whole of North America and down to northern South America. It has 35 geographical races, which can be divided into three main groups.

Identification Tips:

Length is 4 inches. It is a small, active, insect-eating bird. The yellow warbler has a thin, pointed bill, mostly yellow plumage. Its upperparts greenish-yellow

Greenish-yellow wings and tail with yellow featyellow warblerher edges. It has a plain yellow face with yellow eye ring surrounding dark eye and yellowish legs. The adult male has golden yellow plumage with rusty streaks on breast and flanks. Female and immature yellow warblers have plain yellow plumage, their streaks on breast absent or barely noticeable.

They nests in trees, building a cup nest. The female usually lays 3-6 eggs, but the two other groups, which breed in mangroves, lay fewer eggs, as would be expected for tropical races.

yellow warbler pictureThese birds feed on insects and spiders, but northern races will also take some berries. As they are visitors to my bird feeders and will take suet cake offerings.

The yellow warbler song is a musical sweet sweet sweet, I’m so sweet, although it varies considerably between races. The call is a soft or harder ship.

This species is a regular victim of the Brown-headed Cowbird, a nest parasite.

Dark-eyed Junco – Junco hyemalis

Dark-eyed Junco

General: The Dark-eyed Junco is one of the most common birds in North America. Dark-eyed Juncos are birds of the ground. They are common at winter bird feeders and can usually be seen flittering in tree branches and hopping on the ground searching for seeds.Dark-eyed Junco

The White-throated Sparrow and the Dark-eyed Junco occasionally mate and produce hybrids.

Dark-eyed Juncos generally nest on or near the ground.

Dark-eyed Juncos eggs are pale green brown spotted occasionally unmarked. the eggs are approximately 7/10ths of an inch.

The chicks will hatch in 12-13 days and will fledge in 9-13 days

Identification: The Dark-eyed Junco is a medium-sized sparrow, 5″ to 6 1/2″ with a rounded head, a short, stout bill and a fairly long, conspicuous tail. In general they’re dark gray or brown birds brightened up by a pink bill and white outer tail feathers that periodically flash open, particularly in flight.

Males tend to have darker, more conspicuous markings than the females.

Juncos vary across the country, in fact up until the 1980’s several variations of the Dark-eyed Junco, Oregon Junco, White-Winged Junco and Slate-Colored Junco were considered separate species.

Inter-breeding occurs where these variations meet.

Dark-eyed JuncoHabitat: Dark-eyed Juncos breed in coniferous or mixed-coniferous forests ranging from sea level to more than 11,000 feet

Territory: Dark-eyed Juncos can be found from Alaska to Newfoundland south to Mexico and Georgia. They do migrate and in winter can be found as far south as the Gulf coast and Northern Mexico.

Food: Dark-eyed Juncos are primarily seed-eaters. At feeders they seem to prefer millet over sunflower seeds. Dark-eyed Juncos also eat insects.
