Recording Description
Vocalization of a Richardson Ground Squirrel
Notes
Sub-section of repeated whistles issued in multi-caller bout by a yearling female (UD tri-3spots; consistently loudest in recording), a juvenile female (131; second loudest in recording), and a juvenile male (70; faintest and most infrequent calls in recording) that were members of a Richardsons ground squirrel research population at Winnipeg Manitobas Assiniboine Park Zoo) at 0906 CDT on 10 July 2008, in conjunction with the appearance of a mink approximately 40 m north of the calling individuals walking onto the grass out of a wooded area. The microphone was oriented approximately 20 to the right of UD tri-3spots at a distance of 10 m, while it was at an angle of approximately 65 to the right of both 131 and 70, who were within 1 m of each other, 6 m from the microphone. Temperature 19.3 C, Average Wind Speed 4.1 kph out of northeast, Relative Humidity 50%. Equipment: a tripod-mounted Audio Technica AT-815b shotgun condenser microphone, connected via a Tascam US-122L A/D interface to a Getac M220 Laptop running Avisofts Recorder Software. Files were recorded at a 48 kHz sampling rate, and 16-bit sampling depth, though ultimately these were converted on SASLabPro to a 44.1 kHz sampling rate, and then converted to MP3 files using iTunes 9.2.
