Summary

Parrot brains differ from human, primate, mammalian and even other bird brains. Consequently, parrot and human senses may differ (e.g. most parrots have ultraviolet vison; higher flicker-fusion rates and smaller binocular overlap than do primates). Some parrot and human senses are similar (e.g. acute hearing sensitivity range overlap). Grey parrots can perform quite like humans - particularly young children (e.g. number concepts) - sometimes more so than genetically-nearer nonhuman primates. Such aspects affect laboratory experimental design and possibly field studies, although little is known about Greys’ lives in nature. I summarize knowledge about Grey parrot sensory capabilities and their possible effect on cognitive studies, and examine generalizations about behavioural training techniques - particularly how humans’ early evaluations of parrot capacities were prejudiced by not understanding how parrots learn vocalizations and concepts. I review laboratory studies on cognitive and communicative abilities. As to guidance for conducting field work, I discuss the small amount of existent information. This chapter, therefore, is a reference source, not an exhaustive treatise nor detailed guide.
