In recent years the several agency and non-agency groups that make up the Tricolored Blackbird Working Group have worked to accumulate and disseminate information on the population status of the species, identify and suggest management actions for land managers to improve conditions.
Endangered status. In the Department of Fish and Game (DFG) of California, based on significant decline in population numbers documented in the s, added the tricolored blackbird to the published list of "Bird Species of Special Concern".
