Western Bluebill - Spermophaga haematina
Adult male: bill blue with red tip; red from chin to breast and flanks, broken pale whitish-blue eye-ring.
Adult female: bill as male but less red at tip; face black, washed red or maroon.
The song is a low clucking series of 'tack' notes rising
into a trill before dying away, usually give from low thick undergrowth or dense cover; both sexes sing.
Contact note is a fairly sharp (or can be soft to almost
inaudible) 'tip', 'tsik', 'tsip' or even more drawn-out 'tsee'.
