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.
