Close up of a Southwestern willow flycatcher nest at the Las Vegas Wash

Flycatchers surprise with "egg-cellent" development

In a series of firsts for the Las Vegas Wash project and Clark County Wetlands Park, biologists have documented a breeding pair of southwestern willow flycatchers.

After several weeks of carefully observing the pair interact, field staff found their nest, with an egg in it about the size of a marble.

Biologists have only identified breeding territories of the federally endangered species at the Wash a few times during 25 years of formal surveys, and this is the first time in program history they have documented a pair, nest or egg.

The nest is located in a thick patch of cottonwood and willow trees and provides new, exciting evidence of the success of the Las Vegas Wash Coordination Committee’s management of the Wash.
