LC
Lawrence's Goldfinch Carduelis lawrencei

Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and population
This species breeds in central and southern California and western Arizona, USA, and in northwestern Baja California, Mexico (AOU 1983). Its wintering range extends through and beyond its breeding range, into northern California, central Arizona, southwestern New Mexico and formerly extreme western Texas, USA (AOU 1983), and Sonora and probably Chihuahua in Mexico (Howell and Webb 1995a).

Trend justification
This species has undergone a small or statistically insignificant decrease over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).

Ecology
This species inhabits arid to semi-arid open deciduous pine-oak woodland, oak woodland, chaparral, and pinyon-juniper vegetation, often near water (AOU 1983, Howell and Webb 1995a). The species occurs from sea level to 2,500 m (Howell and Webb 1995a).
