Year 2000 Protocol Revision
In 2000, the U.S. Fish and Wildlife Service issued a revision to the Sogge et al. (1997) flycatcher survey protocol. The revision did not replace the 1997 protocol; rather, it modifies the minimum number of survey visits required for certain types of surveys. You can download Adobe Acrobat versions of the USFWS protocol revision and accompanying memo for USFWS Region 1 and USFWS Region 2. Please note that in the USFWS memos, Utah should be included in the list of states within the range of the southwestern willow flycatcher.
Region 1 (CA, NV)
Region 2 (AZ, NM, TX)
Survey Data Forms
The 1997 protocol document includes standardized data forms on which to report flycatcher survey results. There have been periodic updates to the forms, including a new 2004 version that must be used for all Southwestern Willow Flycatcher survey reporting (per May 19, 2004 memo from the USFWS Acting Regional Director, Region 2, Albuquerque). The new form has been improved to include entries for datum, UTM coordinates, and federal/state permit numbers. It also requests all surveys include habitat photographs.
You can download the form as a Word or Adobe Acrobat file.
