Description
[edit | edit source]
Measurements:[2]
- Length: 4.9-5.9 in (12.5-15 cm)
- Weight: 0.5-0.6 oz (15-18 g)
- Wingspan: 8.7-9.4 in (22-24 cm)
They have grey-brown upperparts with small black and white spots and pale grey underparts with a light brown rump. Additional distinctive features include a light grey line over the eye, a long slightly decurved thin bill, a long barred tail and dark legs. They actively hunt on the ground, around and under objects, probing with their bill as their extraction tool. They mainly eat insects and spiders. Its song is a trill that becomes more varied during the nesting season. These birds are permanent residents in the south of their range, but northern populations migrate to warmer areas from the central United States and southwest Canada southwards. They are occasional vagrants in the eastern United States. During the breeding season, they move to dry, rocky locations, including canyons, from southwestern Canada south to Costa Rica to build cup nests in a crevice or cavity, usually among rocks.
