gulvingekasik Cassiculus melanicterus

Spectacular and conspicuous black-and-yellow bird of tropical lowlands in west Mexico. Favors deciduous forest and edges, plantations, and hedges with tall trees; often in towns and villages, especially near streams and rivers. Usually in flocks, moving through the canopy to feed at flowering and fruiting trees, but also feeds readily on the ground; often associates with flocks of jays. No similar species in range. Note the raised crest that flares up like a floppy fountain spray.
