There's a quail on my roof that is seriously bumming me out.

Habits and Habitat
Gambel’s quail inhabit brushy and thorny vegetation of southwestern deserts. They are often closely associated with honey mesquite, although these plants are not essential to the birds’ survival. The birds range up to a mile, often along river valleys and drainages. They use shrubs and trees as a nighttime roost, resting a few inches to a few feet off the ground, a habit not typically found in other desert quail. They appear commonly in the suburbs.

These gregarious birds often join together in groups known as coveys, which may total 20 or more individuals in fall and winter. They produce a location or assembly call, "ka-KAA-ka-ka," to locate a mate or other covey members, issuing the call most often in midmorning or late afternoon. They emit a distinct "chip-chip-chip" when alarmed.

The male could just be calling to other of his group.

This site http://birds.audubon.org/birds/gambels-quail has some of their calls, but it isn't clear which is the "location or assembly call."
