Inference by Exclusion in Goffin Cockatoos (Cacatua goffini).

O'Hara M, Auersperg AM, Bugnyar T, Huber L - PLoS ONE (2015)

Bottom Line: Inference by exclusion, the ability to base choices on the systematic exclusion of alternatives, has been studied in many nonhuman species over the past decade.However, the majority of methodologies employed so far are hard to integrate into a comparative framework as they rarely use controls for the effect of neophilia.Our results indicate that Goffin cockatoos are able to solve such abstract two-choice tasks employing inference by exclusion but also highlight the importance of other response strategies.

ABSTRACT
Inference by exclusion, the ability to base choices on the systematic exclusion of alternatives, has been studied in many nonhuman species over the past decade. However, the majority of methodologies employed so far are hard to integrate into a comparative framework as they rarely use controls for the effect of neophilia. Here, we present an improved approach that takes neophilia into account, using an abstract two-choice task on a touch screen, which is equally feasible for a large variety of species. To test this approach we chose Goffin cockatoos (Cacatua goffini), a highly explorative Indonesian parrot species, which have recently been reported to have sophisticated cognitive skills in the technical domain. Our results indicate that Goffin cockatoos are able to solve such abstract two-choice tasks employing inference by exclusion but also highlight the importance of other response strategies.

Mentions: The touch screen apparatus was placed on a table (1 m x 1 m) with a stone placed in front of it. This stone (approx. 40 cm x 20 cm x 30 cm) served as a perch for the birds. It was approximately the same height as the reward tray, so the birds could easily access the stimuli and the food reward (Fig 1).
