Habitat Structure And Alarm Call Dialects In Gunnison's Prairie Dog (Cynomys Gunnisoni), Bianca S. Perla, C. N. Slobodchikoff Nov 2002

Habitat Structure And Alarm Call Dialects In Gunnison's Prairie Dog (Cynomys Gunnisoni), Bianca S. Perla, C. N. Slobodchikoff

Habitat Assessment and Management Collection

We examined the relationship between habitat structure and alarm call characteristics in six colonies of Gunnison’s prairie dogs (Cynomys gunnisoni) near Flagstaff, Arizona, before and after a mid-summer vegetation change. We found significant differences in alarm call characteristics between colonies, confirming the existence of alarm call dialects. Differences in frequency components but not temporal components of calls were associated with differences in habitat structure. Playback experiments revealed that differences in alarm call structure affected acoustic transmission of calls through the local habitat. Thus, we identify habitat structure as one factor that may contribute to alarm call differences between colonies of …

Sentience Collection

During the past 24 years, I have used a modeling technique (M/R procedure) to train Grey parrots to use an allospecific code (English speech) referentially; I then use the code to test their cognitive abilities. The oldest bird, Alex, labels more than 50 different objects, 7 colors, 5 shapes, quantities to 6, 3 categories (color, shape, material) and uses ‘no’, ‘come here’, wanna go X’ and ‘want Y’ (X and Y are appropriate location or item labels). He combines labels to identify, request, comment upon or refuse more than 100 items and to alter his environment. He processes queries to …
