Yuma Clapper Rail Survey
Southwest Region, May 4, 2007
Print Friendly Version

Five students from Thunderbird High School joined AESO staff biologist  Lesley Fitzpatrick to conduct a survey for the endangered Yuma clapper rail at the Gila River in Buckeye, Arizona.  Students were briefed on the survey protocol on May 3, 2007, and received a CD with the calls of various marsh birds that might be heard during the survey.  At the survey site, the students and Ms Fitzpatrick conducted the protocol and recorded four clapper rails, including one pair that "clattered" invisibly from only a few feet away.  An appreciation of actual survey constraints, in this case sounds of other birds in the area, was also part of lessons learned, as it was difficult to hear the quieter marsh birds over the songs of red-wing blackbirds
