| 説明 | RED-WINGED BLACK BIRD (Agelaius phoeniceus)The red-winged black bird maybe one of the most common birds in North America. Interestingly, this bird is normally associated with freshwater marshes and its breeding range extends from Northern Canada to Central America. The male birds have territories and in fact, in one region up to 15 females were found within a single male's territory! These birds forage during the day, looking for grain and seeds like other black birds, and roost at night.Red-winged black birds are fiercely defensive of their nests and will try to fend off any harassing hawk, crow or even humans. They will hover close and make an aggressive vocal attempt to get get the intruder out. These birds, known for their solid black body and bright red wing, reach about 9.5 to 10.5 inches in length. They are unmistakable in the field... you can't miss the red wing against the black feathers!This bird is likely to be seen perched on a branch during breeding season. Each nesting pair of birds will use twigs and grasses to build a cup shaped nest to hold their brood. Three to five pale blue spotted eggs will be laid by the female. Their diet consists mainly of insects, dragonflies, beetles, butterflies and spiders. Their predators include the coyote, raccoon, owls, red foxes and crows. They play a vital role in our ecosystem by controlling the insect population. Source: www.chinohillsstatepark.org/CHSP/birds.htm |
