Acorn Woodpeckers, with their clown-like faces, are common visitors at feeders in the southwestern US. They get their name from their habit of drilling small holes in trees (and telephone poles) into which they hammer acorns so tightly that even squirrels can't extract them! Acorn Woodpeckers breed in loose colonies of up to 16 birds, and their presence is usually announced by a variety of loud, raucous "WAKE-UP WAKE-UP WAKE-UP" calls. They feed on insects (in addition to the acorns they store up for a "rainy day"), and are often seen "flycatching" insects in midair - a strange behavior for a woodpecker! This one was photographed near a feeder at the Santa Rita Lodge in Madera Canyon, Arizona. Photo taken with a Nikkor 300mm ED f4.5 lens on Ektachrome 400 film. (Date: May 1985)
