Distribution and habitat

Two subspecies nest in the United States. The subspecies A. f. acaciarum is resident from southern California, Nevada, and Utah southward into Mexico; it is associated mostly with the Sonoran Desert. The subspecies A. f. ornatus is found from New Mexico and Oklahoma southward into Mexico and is associated with the Chihuahuan Desert and its scrublands. The remaining 4-5 subspecies are resident to Mexico, and aren't known to migrate into the United States. Verdins nest in shrubs and thorny thickets with few trees. Their nests are best described as spherical masses of bulky twigs and branches that are then lined with grasses, feathers, and hair. The entrance to the nest is about 1" in diameter, and is usually at the bottom of the sphere. They feed in shrub-land and scrubby outcrops where insects are hosted and berries and seeds are plentiful.

Conservation status

Although the verdin is listed as a species of least concern [LC] by the IUCN, The North American Breeding Bird Survey suggests that verdin populations have declined by 1.9% per year between 1968 and 2015. This decline could mean that the species has experienced a cumulative decrease of 60% in that 47-year period. Threats to verdin populations include habitat loss as a result of urbanization, human structure collisions, and predation.
