Ruby-crowned Kinglet

This photo was taken January 18th in Tennessee. A tiny bird seemingly overflowing with energy, the Ruby-crowned Kinglet forages almost frantically through lower branches of shrubs and trees. Its habit of constantly flicking its wings is a key identification clue. Smaller than a warbler or chickadee, this plain green-gray bird has a white eyering and a white bar on the wing. Alas, the male’s brilliant ruby crown patch usually stays hidden—your best chance to see it is to find an excited male singing in spring or summer.

The Ruby-crowned Kinglet is a tiny bird that lays a very large clutch of eggs—there can be up to 12 in a single nest. Although the eggs themselves weigh only about a fiftieth of an ounce, an entire clutch can weigh as much as the female herself.

Brown Creeper

This photo was taken January 18th in Tennessee.  Brown Creepers are tiny woodland birds with an affinity for the biggest trees they can find. Look for these little, long-tailed scraps of brown and white spiraling up stout trunks and main branches, sometimes passing downward-facing nuthatches along the way. They probe into crevices and pick at loose bark with their slender, downcurved bills, and build their hammock-shaped nests behind peeling flakes of bark. Their piercing calls can make it much easier to find this hard-to-see but common species.

The naturalist W.M. Tyler, writing in 1948, captured this species’ energy and fragility in a memorable description, “The Brown Creeper, as he hitches along the bole of a tree, looks like a fragment of detached bark that is defying the law of gravitation by moving upward over the trunk, and as he flies off to another tree he resembles a little dry leaf blown about by the wind.” The Brown Creeper builds a hammock-like nest behind a loosened flap of bark on a dead or dying tree. It wasn’t until 1879 that naturalists discovered this unique nesting strategy. In Arizona, Brown Creeper nests often have two openings, one which serves as an entrance and the other as an exit. Entrances face downward and exits upward.

Ring-necked Duck

This photo was taken January 26th 2014. The male Ring-necked Duck is a sharply marked bird of gleaming black, gray, and white. Females are rich brown with a delicate face pattern. At distance, look for this species’ distinctive, peaked head to help you identify it. Even though this species dives for its food, you can find it in shallow wetlands such as beaver swamps, ponds, and bays. Of all the diving duck species, the Ring-necked Duck is most likely to drop into small ponds during migration.

This bird’s common name (and its scientific name "collaris," too) refer to the Ring-necked Duck's hard-to-see chestnut collar on its black neck. It’s not a good field mark to use for identifying the bird, but it jumped out to the nineteenth century biologists that described the species using dead specimens. During fall migration, Ring-necked Ducks can form immense flocks. Several hundred thousand congregate each fall on certain lakes in Minnesota to feed on wild rice.

Redhead

An aptly named diving duck, the Redhead can be easily identified by its bright red head and gray back. Many female Redheads make no nests of their own, but instead lay their eggs in the nests of other ducks.

Northern Harrier

Was too far away to snap a picture but while looking through a spotting scope, this raptor was easy to recognize. The Northern Harrier is distinctive from a long distance away: a slim, long-tailed hawk gliding low over a marsh or grassland, holding its wings in a V-shape and sporting a white patch at the base of its tail. Up close it has an owlish face that helps it hear mice and voles beneath the vegetation. Each gray-and-white male may mate with several females, which are larger and brown. These unusual raptors have a broad distribution across North America and Eurasia.

Northern Harriers are the most owl-like of hawks (though they’re not related to owls). They rely on hearing as well as vision to capture prey. The disk-shaped face looks and functions much like an owl’s, with stiff facial feathers helping to direct sound to the ears. Juvenile males have pale greenish-yellow eyes, while juvenile females have dark chocolate brown eyes. The eye color of both sexes changes gradually to lemon yellow by the time they reach adulthood. Male Northern Harriers can have as many as five mates at once, though most have only one or two. The male provides most of the food for his mates and their offspring, while the females incubate the eggs and brood the chicks. The oldest Northern Harrier on record was 15 years, 4 months old when it was captured and released in 2001 by a bird bander in Quebec.

Green-winged Teal

We witnessed a Green-winged Teal while participating at the Christmas Bird Count.  We saw it through a spotting scope about 100 yards way wading in a marshy pond.  It was a great sight but to far away to snap a picture of it.

Cedar Waxwing

This picture was taken that the University of Alabama's Arboretum of February 9th.  A treat to find in your binocular viewfield, the Cedar Waxwing is a silky, shiny collection of brown, gray, and lemon-yellow, accented with a subdued crest, rakish black mask, and brilliant-red wax droplets on the wing feathers. In fall these birds gather by the hundreds to eat berries, filling the air with their high, thin, whistles. In summer you’re as likely to find them flitting about over rivers in pursuit of flying insects, where they show off dazzling aeronautics for a forest bird.

Cedar Waxwings with orange instead of yellow tail tips began appearing in the northeastern U.S. and southeastern Canada in the 1960s. The orange color is the result of a red pigment picked up from the berries of an introduced species of honeysuckle. If a waxwing eats enough of the berries while it is growing a tail feather, the tip of the feather will be orange. The Cedar Waxwing is one of the few North American birds that specializes in eating fruit. It can survive on fruit alone for several months. Brown-headed Cowbirds that are raised in Cedar Waxwing nests typically don’t survive, in part because the cowbird chicks can’t develop on such a high-fruit diet. Because they eat so much fruit, Cedar Waxwings occasionally become intoxicated or even die when they run across overripe berries that have started to ferment and produce alcohol.
