Taxonomic Comments
P. californica formerly was included in this species (AOU 1989, Atwood 1988). Subspecies curtata from Isla Tiburon off Sonora is very weakly differentiated from subspecies lucida (Dunn and Garrett 1987).

Range Extent Comments
RESIDENT from northeastern (and possibly eastcentral) Baja California, southeastern California (north to southern Inyo County), southern Nevada, western and central Arizona, southern (rarely central) New Mexico, and western and southern Texas (Rio Grande Valley) south to southern Sonora (including Isla Tiburon), southern Durango, Jalisco, Guanajato, San Luis, Potosi, and Tamaulipas (AOU 1989). See Dunn and Garrett (1987) for distribution of subspecies.
Ecology & Habitat

Diagnostic Characteristics

See Dunn and Garrett (1987) for detailed treatment of field identification of this and other North American gnatcatchers.

Habitat

Tall vegetation in washes, also desert brush and scrub (AOU 1989). Communal roosting in verdin nest has been observed in December. Subspecies LUCIDA: catclaw acacia-smoketree vegetation of desert washes, mesquite brushlands (Biosystems Analysis 1989). Nests in bushes, 60-90 cm above ground (Terres 1980).

Ecology

In riparian habitat along the lower Colorado River, territories varied from 1.01 to 1.78 hectares (Laudenslayer 1981).

Reproduction

Both sexes incubate 4, sometimes 3-5, eggs for about 14-15 days (Terres 1980). Young leave nest when about 9-10 days old. Double-brooded.
