Duration of observation:

Habitat: 

Scrubby chenier, very arid due to drought.  Bird was seen twice on the dusty road cutting across the chenier, and in the acacias flanking the main body of the chenier. 

Behavior of bird: 

Ran along the road quickly, like a plover, and disappeared into the scrub.  I walked closer, slowly, and it popped up into an acacia.  I walked closer, taking pictures, and it flew into the next tree back, then dropped into the grasses and scrub.  

Description:

A smallish/medium-sized passerine with a long thin bill, slightly decurved, slender body, and medium-long,  thin tail. Overall the bird was very drab, blending perfectly with the grayish earth of the road.  Head grayish, mantle fairly evenly colored gray, no contrast with head.  Wings with two distinct white wingbars, the most forward of the two formed by white scalloped edges to dark gray median coverts, the rear wingbar by whitish edges to dark gray greater coverts.  Flight feathers dark grey, edged grayish about as mantle. Underparts whitish, breast and flanks heavily marked with thick dark gray streaks, streaking also concentrated on malar area.  Didn’t see vent/undertail well. Tail appeared slightly darker than mantle, perhaps the same as flight feathers, with white outer corners formed by white tips to 2 or 3 outer primary pairs. Legs not seen well.  Bill gray-based, with ½ to 2/3 tipped blackish.  Eye pale, orange or yellow-orange.         

Voice:

not noted.
