Great-tailed Grackle
Quiscalus mexicanus
Perching
Length: 18 in. (46 cm )
Always associated with moist areas, this grackle has taken advantage of human water use, such as canals, golf courses and reservoirs, to dramatically spread its geographical range in the last 25 years. It is abundant in suburbs and city centers, and during the winter, it forms immense flocks that roost together in the same few trees every night. It feeds on the ground on insects, aquatic invertebrates, fruit, grain and often robs other birds\ nests of their eggs and young. The Great-tailed Grackle twig nests are concentrated in loose colonies of thousands in trees near water.'
The four-digit banding code is GTGR.
