Tricolored Blackbird Colony Destruction, Merced Co., California

The destruction of tricolored blackbird breeding colonies through harvest of the grain crop that serves as the nesting substrate is an annual occurrence in the San Joaquin Valley of California. Typically, the harvest of these grain fields results in complete elimination of the potential productivity of tens of thousands of breeding birds. As a majority of tricolors breeds in the San Joaquin Valley, the losses due to these harvests greatly reduce the number of young born and fledged each year.
