Lesser Nighthawks don’t bother with anything resembling a nest, and we would often come across their eggs nestled into the sandy ground on the Lower Colorado River project.

Gila Woodpeckers are well known for nesting in saguaro cactuses, but did you know they also nest in large trees within riparian forests?

For most of the duration of the Lower Colorado River project, we tracked the presence of breeding colonial waterbirds like this Great Blue Heron.

It’s hard to overstate the relief of a nice rest in the river after a long day of trail clearing through thick saltcedar on the lower Colorado River

Despite the Alamo Dam upstream, the Bill Williams River typically functions more “naturally” than many rivers in the West, subject to high and low flows depending on the season.

The lower Colorado River region is famous for its rarities, and we were not infrequently treated to some great birds on surveys. This stunning Blackpoll Warbler was found during surveys on Lake Havasu and stuck around for several days. Photo by David Vander Pluym.

Yellow Warblers were the most abundant of the covered species on the lower Colorado River project, but their distribution was patchy. The largest numbers were found on the Bill Williams River, but eye-popping densities were found some years at Topock Marsh.

Surveying the randomly selected locations on the Lower Colorado River project took us to some incredible places, and surveyors always got to watch the sun rise.

Did we record threatened and endangered species, like the Southwestern Willow Flycatcher on the Lower Colorado River project? Sometimes, but T&E species were all surveyed by their own specific projects. Most Willow Flycatchers we recorded, including this one, were just passing through.

A highlight of our surveys on the Lower Colorado River project was finding and confirming the first breeding record of the Nutting’s Flycatcher in the United States. A small population persisted for several years, & some territories were even mapped on our survey plots.

Verdin is a common species on the lower Colorado River, using a variety of habitats including riparian forest. At Yuma East Woodlands, the mind-boggling density of this species had surveyors’ heads spinning!

Old-growth saltcedar (tamarisk) forests can get very dense when they have ample water and little disturbance, and the Lower Colorado River project crew became extremely skilled at navigating these thickets.

The lower Colorado River is no place to keep your feet dry! Here, part of the 2013 Havasu crew is enjoying cooling off in the Bill Williams River.
