The folks in the Riverwalk Bird Club don't just watch birds. The group includes some excellent photographers.

Nooga.com Outdoors is happy to share their great photos by featuring a Bird of the Week.

This week, we feature a killdeer, taken by Charles Dean.

Interesting facts
These tawny birds run across the ground in spurts, stopping with a jolt every so often to check their progress or to see if they’ve startled up any insect prey. Their voice, a far-carrying, excited "kill-deer," is a common sound even after dark, often given in flight as the bird circles overhead on slender wings.

—Killdeer get their name from the shrill, wailing "kill-deer" call they give so often. Eighteenth-century naturalists also noticed how noisy killdeer are, giving them names such as the "chattering plover" and the "noisy plover."

—Gravel rooftops attract killdeer for nesting but can be dangerous places to raise a brood. Chicks may be unable to leave a roof because of high parapets and screened drain openings. Adults eventually lure chicks off the roof, which can be dangerous—although one set of chicks survived a leap from a seven-story building.

—The killdeer’s broken-wing act leads predators away from a nest but doesn’t keep cows or horses from stepping on eggs. To guard against large, hoofed animals, the killdeer uses a quite different display, fluffing itself up, displaying its tail over its head and running at the beast to attempt to make it change its path.

—A well-known denizen of dry habitats, the killdeer is actually a proficient swimmer. Adults swim well in swift-flowing water, and chicks can swim across small streams.

—The male and female of a mated pair pick out a nesting site through a ritual known as a scrape ceremony. The male lowers his breast to the ground and scrapes a shallow depression with his feet. The female then approaches, head lowered, and takes his place. The male then stands with body tilted slightly forward, tail raised and spread, calling rapidly. Mating often follows.

—Killdeer lay their eggs into an empty nest but add other materials later on. Some of these items they pick up as they are leaving and toss over their shoulder into the nest. In one nest in Oklahoma, people found more than 1,500 pebbles they had accumulated this way.

—The oldest known killdeer was 10 years, 11 months old.
