Sandhill Crane

Description:

Height: ~80 cm-1.2 m, 3-5 ft Weight: ~ 3-6.5 kg, 6.5-14 lbs Wingspan: ~5-6 ft. Population: ~650,000 The different sub-species of Sandhill Crane vary greatly in size and weight. Lesser Sandhills, who breed at more northern latitudes such as the arctic, are the smallest, weighing on average about 6-7 pounds and standing 3-3.5 feet tall. At the other end of the extreme, temperate-nesting Greater Sandhills are the largest sub-species and average 4.5-5 feet tall and 10-14 pounds. Body plumage is characterized by varying shades of gray. In many areas, wild Sandhills preen iron-rich mud into their feathers creating a deep rusty brown hue which lasts during spring and summer. As fall advances, these rusty feathers molt and the birds return to their grayish appearance. In some regions, however, iron-rich mud is absent and the birds appear grey all year. The forehead and crown are covered with reddish skin. Face, chin, upper throat, and nape are white to pale gray. Adults have a white cheek patch. Legs and toes are black. In general, males and females are virtually indistinguishable but within a breeding pair, males tend to be larger than females.

Habitat:

Sandhill Cranes are the most abundant of the world's cranes. They are widely (though intermittently) distributed throughout North America, extending into Cuba and far northeastern Siberia. The three migratory subspecies (Lesser, Greater and Canadian) are distributed across a broad breeding range in the northern U.S. and Canada as well as eastern Siberia, with wintering grounds in the southern United States and northern Mexico. The three non-migratory subspecies (Mississippi, Cuban, and Florida) have restricted ranges in the southern United States and Cuba. Sandhill Cranes are primarily birds of open fresh water wetlands, but the different subspecies utilize habitats that range from bogs, sedge meadows, and fens to open grasslands, pine savannas, and cultivated lands. Sandhill Cranes occur at their highest breeding density in habitats that contain open sedge meadows in wetlands that are adjacent to short vegetation in uplands. Mated pairs of cranes, including Sandhill Cranes, engage in unison calling, which is a complex and extended series of coordinated calls. While calling, cranes stand in an upright posture, usually with their heads thrown back and beaks skyward during the display. In Sandhill Cranes the female initiates the display and utters two, higher-pitched calls for each male call. While calling, the female raises her beak about 45 degrees above the horizontal while the male raises his bill to a vertical position. All cranes engage in dancing, which includes various behaviors such as bowing, jumping, running, stick or grass tossing, as well as wing flapping. Though it is commonly associated with courtship, dancing can occur at any age and season. Dancing is generally believed to be a normal part of motor development for cranes and thwarts aggression, relieves tension, and strengthens the pair bond. Nests of all Sandhill Cranes are usually low mounds built out of dominant vegetation in the nesting area. Typically nests are located in wetlands, but Sandhill Cranes will sometimes nest in uplands, especially in Cuba. Females usually lay two eggs and incubation (by both sexes) lasts 29-32 days. The male takes the primary role in defending the nest against possible danger. Chicks fledge (first flight) at 67-75 days.

Notes:

I found this bird wondering along a wetland area, in a local park. It was with one other bird. Because of the mild winter we had in our State, these birds showed up a bit earlier then normal.
