EspañolWEDGE-BILLED WOODCREEPER
(Redirected from Glyphorynchus)
The 'Wedge-billed Woodcreeper' (''Glyphorynchus spirurus''), is a passerine bird which breeds in the tropical New World from southern Mexico to northern Bolivia, central Brazil and the Guianas. It is the only member of the genus ''Glyphorynchus''.
This common and widespread small woodcreeper is found in lowlands up to 1500 m altitude, although normally below 1100 m, in damp forests, adjacent semi-open woodland and old second growth. It builds a cup nest in a narrow tree cavity such as a rotting stump or space between buttresses. It may occasionally nest up to 6 m high in a tree, but is usually much lower, often at or below ground level. It lays two white eggs between March and June.
The Wedge-billed Woodcreeper is typically 14-15 cm long, and weighs 14-16.5 g. It has brown upperparts, with fine streaking on the head sides, a buff supercilium, and a chestnut rump, wings and tail. The throat is buff, and the rest of the underparts are brown spotted dwith buff chevrons, most heavily on the breast. A buff wing bar is obvious from below in flight. The short wedge-shaped bill is quite different in shape from that of other woodcreepers. Young birds are duller with less distinct breast streaking.
The call is a sneezy ''schip''. The song varies geographically, perhaps refecting the different subspecies of this bird. In Costa Rica it is a trilled ''keekekekiki'', whilst in eastern Bolivia it is an ascending ''too-e too-e tu-tu-tu-tue-twu-twu-tweeet''.
The Wedge-billed Woodcreeper is easily distinguished from its relatives by its small size and distinctive bill. It feeds on small spiders and insects, creeping up trunks and extracting its tiny prey from the bark. It has a strong preference for trees with fine flaky bark. It is seen alone, in pairs, or sometimes as part of a mixed-species feeding flock.
