This passage describes an elegant and slender bird that is commonly seen in open areas, either in flight or perched on exposed snags or telephone wires. The adult bird has green feathers overall, a blue tail, a thin black mask, and a rufous throat. Its bright rufous underwings are visible during flight. The juvenile bird looks similar but appears paler, with a tannish throat and a shorter tail that lacks the adult’s elongated central tail feathers. This flying bird has a distinctive shape, with broad and sharply pointed wings, a long tail, and a long bill. The bird nests colonially in sandbanks. Its voice is described as a sweet, clipped “cheer-it,” sometimes given in a series.
