During those spring and fall months in Lancaster County farmland, I see them perched on roadside poles and wires to watch for horned larks, starlings, sparrows and other kinds of small birds, or zipping swiftly and low across fields to scare up those same birds in fields. Merlins also sweep quickly over mud flats and beaches to chase up sandpipers and plovers, to catch one of those shorebirds at a time.
