Medium81 gShrubland

The curve-billed thrasher is immediately recognized as a thrasher by its long tail and short wings. It is also recognized for its sickle-shaped bill, almost as long as its head width and brownish black in color. The body is compact with a large head, short wings and long tail. However, the tail is short relative to other thrasher species. The chest is grayish brown with circular brown-gray spots. The eyes are generally orange, shading to golden in adulthood. Juveniles are lacking in pale tips, rectrices, abdominal feathers are unkempt and upper parts and chest are washed rufously.

Grey Catbird (Dumetella carolinensis)

Grey Catbird

Dumetella carolinensis

Small35 gShrubland

Adults weigh from 23.2 to 56.5 g (0.8 to 2.0 oz), with an average of 35–40 g (1.2–1.4 oz) They range in length from 20.5 to 24 cm (8.1 to 9.4 in) and span 22 to 30 cm (8.7 to 11.8 in) across the wings. Among standard measurements, the wing chord is 8.4 to 9.8 cm (3.3 to 3.9 in), the tail is 7.2 to 10.3 cm (2.8 to 4.1 in), the culmen is 1.5 to 1.8 cm (0.6 to 0.7 in) and the tarsus is 2.7 to 2.9 cm (1.1 to 1.1 in). Gray catbirds are plain lead gray almost all over. The top of the head is darker. Voice: This species is named for its cat-like call. Like many members of the Mimidae (in particular mockingbirds), it also mimics the songs of other birds, as well as those of Hylidae (tree frogs), and even mechanical sounds. Because of its well-developed songbird syrinx, it is able to make two sounds at the same time. The alarm call resembles the quiet calls of a male mallard.
