A small bird with a yellow throat, skulking in the grass or weeds of a marshy spot, is almost certainly a Common Yellowthroat, whose cheerful song is well known. At the height of the breeding season, the males perform an attractive flight display, mounting into the air while uttering a jumble of high-pitched notes, then bouncing back into the grass while giving the usual song. To foil predators, parents drop down into the thick of the grasses or weeds, secretly approach their well-hidden nest, deliver the food, and depart by another route. The bird is the northernmost member of a group of yellowthroat species that occurs as far south as Argentina.
