Montane Woodcreeper

The montane woodcreeper is 19 to 19.5 cm (7.5 to 7.7 in) long; males weigh 31 to 35 g (1.1 to 1.2 oz) and females 29.5 to 33 g (1.0 to 1.2 oz). It is a smallish to medium-sized woodcreeper with a slim, slightly decurved bill. The sexes have the same plumage. Adults of the nominate subspecies L. l. lacrymiger have a markedly streaked face and neck with a whitish supercilium that is often broken. Their crown and nape are dusky brown with conspicuous whitish buff spots with black tips; the spots become streaks on the nape. Voice: The montane woodcreeper is not highly vocal. Its song is "a 2·5 second series of 10–15 high-pitched whistles that accelerates and descends: 'tsip, tsip, tsip, ts-ts-tseeeéu, tseeu, tseu-tseu-tseu-tseu' or 'tseu, tseu, tsip-tsip, tsee-tsee-tsee-tsee-tsee' ". It also makes a "series of 3 reedy squeaks", a "double-noted cry", and a "rattle with introductory 'ah' ".
