Individual variation in spontaneous problem-solving performance among wild great tits (2011, background): “…that the large sample sizes needed for the study of individual variation are often difficult to obtain, especially for cognitive traits, the measurement of which commonly requires extensive subject training or repeated trials (e.g. Weir et al. 2002; Tebbich & Bshary 2004; Heinrich & Bugnyar 2005).”
A case of quick problem solving in birds: string pulling in keas, Nestor notabilis (2006, methodology): “Four of those successful keas retrieved the food object dangling on a string instantaneously and without showing exploratory or ineffective methods (such as flying up from the ground or pecking at the string as ravens did; see Heinrich & Bugnyar 2005 ).”
Technical innovations drive the relationship between innovativeness and residual brain size in birds (2009, unknown): “…is consistent with studies of problem-solving ability in captive birds, wherein large-brained birds are able to spontaneously solve novel tasks that may require very specific technical skills unlike those they use in the wild (Webster & Lefebvre 2001; Heinrich & Bugnyar 2005; Biondi et al. 2008).”
A comparison of innovative problem-solving abilities between wild and captive spotted hyaenas, Crocuta crocuta (2013, background): “…of inducing innovation by presenting captive individuals with a novel problem-solving task (Köhler 1925; Visalberghi et al. 1995; Povinelli 2000; Heinrich & Bugnyar 2005; Santos et al. 2006; Bond et al. 2007; Tebbich et al. 2007; Boogert et al. 2008; de Mendonca-Furtado & Ottoni 2008; Liker &…”
