·         Fee-bee.--The Fee-bee, produced as far as we know only by males, typically consists of two whistled notes

·         Fee-bee calling begins in late December or early January and continues into November, though sporadically in the fall. The period of most intense vocalizing is April-July.

·         When a male that is within a winter flock calls, he first isolates himself temporarily from group members, and we never saw a male utter these vocalizations while in close proximity to others.

·         During the breeding season males engage in short bouts of calling as they move around their territories, but we feel that they call much less frequently than do territorial males of other species
