In the grassy meadows of Oasis Valley, Savannah sparrows seem to be present in varying numbers throughout the year. I can't find them every time I look for them, yet at other times several fly up from the grass as I walk though the valley floor. Spring and fall migrants may move through the area, and a few different subspecies may occur. Some are darker brown and others are lighter tan in color.
They prefer dense Saltgrass (Distichlis spicata), stands of Nevada bluegrass (Poa secunda spp. juncifolia) along the Amargosa River, and marshes of rush (Juncus mexicanus), bulrush (Schoenoplectus pungens), and Cattails (Typha spp.). I also often flush them from stands of Iodine bush (Allenrolfea occidentalis) in alkaline meadows.
^Great habitat for Savannah sparrows, of Saltgrass, Nevada bluegrass, and rushes.
Calls of a soft "tsip" can be heard all year, and in spring the sparrows sing their buzzy songs in the grassy meadows.
