The diet of the brown thrasher consists mainly of invertebrates, predominantly beetles, although fruits and nuts are increasingly consumed outside of the breeding season (3). This species is a ground forager, searching for its food by using its long bill to sweep through leaf litter and soil (2) (3).
The brown thrasher breeds from May to June, with the male singing from conspicuous places such as treetops in order to establish a territory and attract a mate. Although the brown thrasher does not engage in elaborate courtship displays, the male has been observed to sing a soft courtship song to the female (3). Both sexes take part in nest building, constructing a bulky cup of twigs in dense shrubs, or sometimes on the ground (2) (3).
A clutch of between two and six eggs is laid in the nest and these are incubated by both the male and female brown thrasher (3). The chicks hatch after 10 to 14 days and are fed by both adults until they leave the nest, fully feathered, at only 9 to 13 days old (2) (3). During the breeding season, the brown thrasher defends its nest aggressively. It will chase and attack potential predators and has been observed attacking snakes, dogs and even humans (3). Adults will also engage in ‘broken-wing’ displays, feigning injury in order to lure potential predators away from fledglings (3).
