Chestnut-capped Piha

Overall the chestnut-capped piha is a dark grey bird with a notable chestnut crown on the upper nape and pale cinnamon-colored undertail coverts. The upperparts and wing coverts are a dark grey with paler fringes to most of the feathers. The flight feathers are a dark brownish grey with cinnamon-colored fringes on the secondaries and tertials. As the bird's feathers wear, the pale fringes tend to darken, leaving the bird even more uniform grey in coloration. The underwing is a pale silvery grey. The underparts are a paler shade of grey than the upperparts, particularly on the throat. Voice: Like most pihas, the chestnut-capped piha is extremely and conspicuously vocal. Its call is a loud, piercing sreeck which rises in pitch before abruptly descending. These calls are given repetitively in a series at one-second intervals, although when agitated they can be given every third of a second, and can be heard over 100 m (330 ft) away.
