title: Red-eared firetail
context: The red-eared firetail is a seed eating estrildid, discreet and unusually solitary for an Australian grass finch species. This species often remains unobserved in dense vegetation while foraging in the lower storey. Their presence is revealed by distinctive calls and the bird is most frequently seen when perched high on the limb of a tree such as marri.[14][18] The individuals form mated pairs rather than grouping. Their individual range is an area around one to two hundred metres across and they may join others while feeding where their territories overlap. Earnest defence of sites only occurs close to the nest, so boundaries between pairs may intersect without incident.[13] Fledglings are eventually fought and driven from the nest site.[10]
