What kind of bird is this? Does anyone know? I found it in the park.

Habitat in open woodlands, especially by the water. Often sing in the morning, 24 ~ 26 times per minute, stop singing for half an hour. Sexual cowardice is often hidden in leaves. Usually I only hear singing, but I seldom see it. Flying fast, walking in a straight line, often have to slide a distance before landing. Feeding on Lepidoptera larvae, beetles, spiders, snails, etc. Eating in large quantities has a considerable effect on eliminating pests.

Rhododendron is lonely and does not live in pairs during the breeding period. Males and females mate promiscuously, instead of building their own nests, they put their eggs in the nests of other birds (such as reed warblers, sparrows, gray magpies, finches, shrikes, larks, snipes, etc.). ). The eggs produced are similar to the host eggs. The egg size is about 23.6× 18. 1 mm, and the shell is thick. The incubation period is 12 ~ 14 days. Eat caterpillars that other birds dare not peck, such as pine inchworm and pine caterpillar.
