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.

This photo shows foxtail pine cones in different stages of development. The small, tightly closed purplish cones are the most recently formed, the ones on the right older but not yet opened, and the one in the center of the image has already opened and dropped its seeds, which are tucked at the base of the scales.

This is what an unburned mid-elevation community in the Hackberry region of the Mojave National Preserve looks like. Note the dense cover and high diversity of shrubs. There are few if any invasive plants in the community.
