NOTES: Neotropical Institute Cut # 18. Bulk reel: 50; Extra cut length: 5:52 BWeather: Fair.a) Type B song, given naturally. Quality: 2-3. Level: +10.b) Type A song (probably a different individual, same side road) after playback of field tape. These are long songs and with varying pitch. Quality: 2. Level: +10.(Another owl heard in type A song in background.)Continuation of [owl heard in background singing type A song]. Songs become shorter but still change pitch (also get louder in last part of song). Quality: 2. Level: +5.I then played back the type B song from field tape. The bird was silent for ~ 15', then started to sing Type A song. This recording starts 5-10' after bird had started singing. These songs are of +/- normal duration but still change pitch. (Then I recorded some song "off focus.") This owl then collected (= male #6206).Note: The owls heard in this area up to 11:00 PM are --O. atricapillus - at least 3-4 individuals (all on west side road)Glaucidium brasilianumCiccaba huhulaPulsatrix perspicillataand possible a Barn Owl [Tyto alba].16/XI/67 Also heard Lophostrix cristata.

ML: Background subject changed from Megascops atricapilla to M. guatamalae to reflect current taxonomy. -Jay McGowan 2Sep2015.
