Description of the Bird

My observations of the bird were relatively brief.  I heard it singing vigorously ('Che bek' call, repeated every 2-3 seconds), and that is what drew my attention to it.  I walked up towards it, and saw enough to confirm that it was an empid.  I did not see enough visual evidence to distinguish it from other empids.

Similar Species Discussion

I used voice (song) as the only way of separating this bird from similar species.

Resources Used

My memory of their song, based on past experience.

Previous Experience

I have seen about a dozen Least Flycatchers in Colorado in Spring, with a few of them singing.  Outside Colorado, my primary experience was in Saskatchewan, where they were singing on territory.

For other western empids, I have seen and heard them on territory multiple times,  My experience with eastern empids (Acadian, Yellow-bellied) is much more limited.

Location Map

The marker on the map shows an approximation of the location of this report. The marker is generated using a prioritized Logic base:
1) If the observer has entered coordinates, they will be shown.
2) No specific coordinates are available but the location is mappable.
3) A generic location with no specific coordinates is mapped to the center of the reported county.
