William W. H. Gunn
23 May 1961
- Spruce Coulee, Cypress Hills Prov. Park
- NAGRA III
NOTES: "Identification not certain, but believed to be this species; Two types of call:'pee' + 'pee-whit'; about 20' up in popular in cut-over bottom land" (WWHG)
LNS: Based on Gunn's uncertainty in his identification, the locality of this recording (outside of the range of both E. difficilis and E. occidentalis), and a comparison with other Empidonax recordings, the subject of this recording was changed from E. difficilis to E. oberholseri. -Matt Medler, 25 Jan 2011.
