The family of Warblers is often nickname, “the butterflies of the bird world.” The warblers are very active birds, at times they will flash their tail, showing their yellow or orange colors to scare out insects that are hiding so they can try to catch them when they fly off.
They eat mostly insects, like beetles, moths, aphids, spiders and etc; their diet also includes some berries and seeds.
When it is mating season, and the female has picked her mate, she will build her nest; she may at times use an old nest that another bird had build. She can have from 2 to 5 eggs in her nest. She sits on the nest for about 11 days or so. Both parents will feed the young birds in the nest. The young chicks will leave the nest when they are about 9 days old. The parents will then divide the chicks up, each parent taking care of half the fledgling.
