Two types of vocalizations of White Carneaux pigeons were identified in experiments on schedule-induced aggression and were given pictorial representation in sound spectrograms. Characteristics of these vocalizations are examined in the context of previous descriptions of vocalizations of several varieties of pigeons during aggressive and sexual encounters(More)
This work assessed the extent to which the food preferences of dogs housed in testing-kennels are representative of those reported for dogs housed in consumers' homes. Experiment 1 compared two-pan preference data from kennel-dogs and home-dogs fed canned, semi-moist, or dry food products. Kennel- and home-dogs performed similarly on the canned-products(More)
The feeding behavior of dogs in one-pan and two-pan tests was measured in the usual way (total food intake in the test) and at a fine-grained level (cumulative amount eaten on a moment-by-moment basis during the test). The four experiments reported studied dogs' reactions to different dry foods, and to semi-moist and canned foods. The fine-grained measures(More)
The authors discuss two principal points. First, what appear to be contradictory findings in the feeding studies in this monograph can be resolved by clarifying two terms: palatability and preference. Second, some of the work in the monograph resulted from an academic and industrial relationship. This relationship was judged mutually beneficial and(More)
