crissal

Some of the relatively understudied species were Philadelphia vireos, crissal thrashers, black-chinned sparrows, and olive warblers.

Crissal Thrasher is uncommon in Coahuila.

The subspecies dumosum of the Crissal Thrasher in Coahuila has been reported only from the southeastern section of the State.

The cactus wren and crissal thrasher build in the geographical centres of tree choyas, so protected by 500,000 spines that no hawk or owl can reach them.
