RUFOUS TWISTWING Cnipodectes superrufus

Endemic; bamboo forest specialist; Vulnerable. In August–September 2014, TNM observed one in bamboo patches near the reserve headquarters; see Melo et al. (2015) (Fig. 3B). On 5 June 2018, DPG trapped and ringed (CEMAVE F55386) one in a bamboo patch, and on 1 August 2018, JML trapped and ringed a second individual (CEMAVE F63509) in a part of the forest apparently without any major concentration of Guadua bamboo, whereas the species typically occurs in patches of dense bamboo (Tobias et al. 2008). HFR is the northernmost locality at which C. superrufus has been recorded (Melo et al. 2015, Guilherme 2016).
