Near Threatened

The species's population was estimated at c.180,000 individuals in 2003, but is thought to have been reduced by 49% by 2006 (del Hoyo et al. 2009) owing to West Nile Virus. Partners in Flight estimate the population to be 90,000 individuals (Partners in Flight Science Committee 2013). The population now appears to have stopped its decline and may have recovered somewhat (W. Koenig in litt. 2016), thus the population is placed in the band for 50,000-99,999 mature individuals, which is assumed to equate to c.75,000-150,000 individuals in total. Read More

The predominant threat to the species is mortality caused by West Nile Virus, which was first documented in California in 2003 (Reisen et al. 2004). This virus caused a crash in the population until 2007-2008, after which some recovery is evident (W. Koenig in litt. 2012). Prior to 2004, the species was locally abundant in some areas, but declining in others owing to urban development on oak savanna, for example in Salinas Valley and areas south of San Francisco (del Hoyo et al. 2009). Habitat is also being lost to agricultural expansion. In addition, the species is susceptible to poisons ... Read More
