The overall condition of oak woodland-associated birds is Good.
Point Blue Conservation Science analyzed patterns of abundance from 1996 to 2013 to determine the trends for as many individual species as possible (see References below). We were able to determine trends for five of the eleven oak woodland-associated species. Trend for the American Kestrel was determined based on unpublished information from the Golden Gate Raptor Observatory and Audubon’s Christmas Bird Counts.
While the condition rating is Good, we lack sufficient information to determine trends for five species. Another species, the Western Scrub-Jay, showed significant declines. The reason for this decline is unknown but the timing corresponds with the emergence of West Nile Virus and Sudden Oak Death, to which this jay may be particularly susceptible. Because this species plays an important role in acorn dispersal, and hence overall condition of oak woodlands, continued ongoing monitoring is essential to determine when active management might be needed.
