Edge detection in landing budgerigars (Melopsittacus undulatus). [PDF]
PLoS ONE, 2009 BackgroundWhile considerable scientific effort has been devoted to studying how birds navigate over long distances, relatively little is known about how targets are detected, obstacles are avoided and smooth landings are orchestrated. Here we examine how

Cognition, personality, and stress in budgerigars, Melopsittacus undulatus. [PDF]
Behav Ecol, 2017 To study the fitness effects of individual variation in cognitive traits, it is paramount to understand whether traits such as personality and physiological stress influence cognitive performance. We first tested whether budgerigars showed both consistent personalities and cognitive performance across time and tasks. We tested object and food neophobia,
