Use of Space in Open Field by Zebra Finches

Abstract

This paper is a descriptive study of the spatial preferences of the zebra finch, Taeniopygia guttata, when exposed to a novel environment. 18 subjects were observed in a cubic open field of 1 × 1 × 1 m during four 30-min. sessions. Two spatial variables were considered, height and center/periphery. Data show that birds did not position themselves randomly in the open field but chose more frequently the central and higher part of the enclosure and that general activity was greater when the animal was in the center rather than on the periphery. There were no sex differences in the height preferred, but females spent significantly more time in the center than did males. The type of activity engaged in by the birds was also important in relation to the place occupied.
