This scarce species is thought to have a moderately small population size, with highly fragmented populations occurring over a wide range. It is likely to be declining owing to habitat loss in parts of the range. It is therefore considered Near Threatened.

Philydor ucayalae Collar and Andrew (1988)
Size: 19 cm. Summary: A scarce uniform furnarid with a distinctive large upturned bill. Id: Massive bluish (except blackish on ridge) bill with upturned lower mandible. Above rufescent brown, rufous brown, duskier on crown and wings, rump and tail rufous chestnut. Poorly defined ochraceous supercilium. Underparts orange rufous with faint flammulations on sides of throat and breast. Immature with more conspicuous supercilium and black scalloping on underparts. Similar: Bolivian Recurvebill S. striatus is not sympatric. Chestnut-crowned Foliage-gleaner Automolus rufipileatus and Brown-rumped Foliage-gleaner A. melanopezus are similar and occur sympatrically but both lack the massive up-turned bill. Hints: favours areas of Guadua bamboo where it forages singly or in pairs, rarely in association with flocks. Best located by call, song or hammering sounds as it forages. Voice: Frequently given call a distinctive loud repeated "chek"; song a fast sharply ascending series of harsh nasal notes lasting about 5 seconds.
