Mixed Diglossini, May 18, 1965, VII.  (50)

and overlapping occurs.  At very low intensities of motivation, the species grow "careless" - and (again) overlapping occurs.

^[[Scan]] III. This afternoon I worked in area on banks of Cauca near Popayán.  I saw a Scan there (definite). This means that the presumed Scans I saw a few days ago in scrub and tree along small stream near Popayán probably (almost certainly) were identified correctly.

^[[Scan]] ^[[Gen]] In spite of the fact that hummingbirds in general are very common in scrubby areas around Popayán, Scans [[underlined]] certainly [[/underlined]] are rare. The habitat  preference(s) of Scans do, in fact, seem to be much more similar to those of most Diglossini than to those of most other hummingbirds.

^[[BQ]] ^[[Scan]] I have yet to see a BQ along banks of Cauca. This would support the hypothesis that territories BQ's and Scans do not overlap in such area. (Although both species seem to be so rare that the apparent absence of overlap may be an artifact of the brevity of my observations.)

May 19, 1965
Region of Puracé

Arrive same place as yesterday morning 5:20 a.m. Still quite dark. Sky half cloudy.

^[[Scan]] ^[[Ater]] Various sub-oscinine and thrush sounds. Then one burst of what may be Scan song 5:27. Shuts up immediately. Then I hear lots of Ater Songs. From several areas. Neighbors overlapping.

^[[Ater]] Ater Song phrases fairly short - altho probably slightly longer on the average than late yesterday morning. Without R components.
 
The Aters I am listening to now are not the same individuals 

Transcription Notes:
I have used 'Scan' throughout but not being a birder suspect this isn't correct.
