WERC A Silky Flycatcher with a Mistletoe Berry
A female silky flycatcher with a mistletoe berry in her beak. These flycatchers are intimately tied to mistletoe. They build their beautiful cup nests (much like a large hummingbird nest) within the mistletoe, or nearby. The young hatch during February when the mistletoe may be in flower and supply a rich source of insect nutrients for growing young.
