[QUOTE="pbjosh, post: 3454428, member: 117939"] Interesting. I guess a negative playback test result would be informative but in this case a positive just is not really. I have had a few cases of using playback with Tapaculos in sites where there are 2-4 species and when you get a glimpse at a bird it is NOT the species you were calling. Most recently, at Bosque Unchog in Huanucó, Peru, while trying to see Neblina Tapaculo (S. altirostris) I am nearly certain that the first bird I saw was Tschudi's (S. acutirostris). I later saw a second individual that seemed to confirm, as Neblina is much paler than female Tschudi's, enough to be fairly distinctive it seems. I am certain there are times when I've heard only one species, used playback, seen a Tapaculo that looked like that species, but actually been wrong! [/QUOTE]
