Conservation

Tamaulipas Crow has a large geographic range, and its population has been suspected to be stable. Consequently BirdLife International (2013) evaluates its global conservation status as Least Concern, and populations in Mexico are not threatened. Eitniear (2013), however, suggests that the population size of Tamaulipas Crow decreased by 50% between 1973 and 2000, and again by 50% after 2001; based on this assessment, Eitniear recommends that Tamaulipas Crow be revised to Vulnerable.

The relative abundance of Tamaulipas Crow in Mexico was assessed as fairly common to common (Howell and Webb 1995), although recent field surveys suggest that it has become much less common throughout its range (Eitniear 2013).

Effects of human activity on populations

No threats to Tamaulipas Crow are identified by BirdLife International (2013). Eitniear (2013) suggested that the population of Tamaulipas Crow has declined drastically in recent decades; possible causes of such a decline include changing land use practices (which are hypothesized to affect the availablility of food for the crow) and the effects of West Nile virus (Eitniear 2013).
