![]() One or more birds swoop down on intruders, performing a synchronized aerial mobbing attack, narrowly missing the predator. One dramatic anti-predator display is a dive-bombing action. When threatened, an American avocet can be aggressive, especially near nesting areas. Both parents will tend the chicks for 28 to 35 days after hatching until they learn to fly. The precocial, downy young can leave the nest soon after hatching with the ability to run, swim and feed themselves. American avocets will lay their eggs in the nest of another American avocet or other species of wetland birds. Eggs of other wetland species such as black-necked stilts and common terns are often found in American avocet nests. Parasitism is rather common in avocet communities. The parents take turns incubating the eggs for 23 to 29 days. Should the water level rise, the breeding pair will raise the nest up a foot or more with sticks, weeds, bones and feathers to keep the eggs above water.Ī female will have three to four eggs during the nesting season. Occasionally, the nest will be lined with grass or other vegetation, feathers, pebbles or other small objects, but generally the nest is unlined as if the bird sees covering the ground as wasted motion. Nest construction consists of creating mere depressions on the sand, platforms on mudflats or a scrape on the ground. These birds nest in colonies from April to June. After copulating, the pair intertwines their necks and runs forward in an elaborate, ritualized display of territory establishment and self-defense. In his pre-copulation display, the male preens himself with water, gradually gaining intensity to the point of frenzied splashing just before he mounts the female. Some nonbreeding one-year-olds return to the breeding grounds where they hatched in the spring.Īmerican avocets are monogamous birds that find mates in the springtime through elaborate courtship behavior. American avocets prefer open water and marshy spring and summer habitats such as lakes and ponds throughout the central plains of the United States, including the Rocky Mountain region and southern Alberta and Saskatchewan. Northbound migration occurs from March to May. American avocets commonly feed solitarily but may feed in flocks – a line of birds advancing abreast.Ī year in the life of an American avocet begins and ends with migration. Additionally, these birds will venture into deeper water and dabble much like a duck would. Generally, American avocets will search for their meal of aquatic plant life and animals such as insects and crustaceans using a sweeping motion of their bills, but they are also known to probe into mud in search of food. In Latin, “recurv” means upcurved, and “rostrum” means “beak of a bird” which comes from the word for a prow of ancient Roman ships. The long beak, one if its defining features, is what gives the American avocet its scientific name, Recurvirostra americana. This bird’s body has a distinctive, black and white striped pattern on its posterior and flanks, while the abdomen and underbelly are white. The American avocet is medium-sized – 18 to 20 inches tall. It’s easy to spot these birds, but still a treat when one appears in your view. Its nickname is “blue shanks,” but the more commonly used name for this bird is American avocet.
