The California scrub jay hides caches of food and will later re-hide food if it was watched by another bird the first time, but only if the bird hiding the food has itself stolen food before from a cache. [72] A male Eurasian jay takes into account which food his bonded partner prefers to eat when feeding her during courtship feeding rituals. [73]
The book explores birds as thinkers (contrary to the cliché "bird brain") in the context of observed behavior in the wild and brings to it the scientific findings from lab and field research. [2] New research suggests that some birds, such as those in the family corvidae, can rival primates and even humans in forms of intelligence.
The information centre hypothesis (ICH) is a theory that states bird species live in communal roosts primarily for the advantage of gaining information from others in the community regarding the location of unevenly distributed food resources. [1] This hypothesis was first proposed by Peter Ward and Israeli biologist Amotz Zahavi (1973). [1]
Two birds dropped out after a lack of interest in the tablet, while one bird showed signs of stress and anxiety. Caretakers recorded their parrots at home, keeping them on a familiar schedule.

Irene Pepperberg said the reward system is crucial, because it is the only way that students can make the direct connection between the object and the label that they have used. Food rewards are also sparingly used. Trainers sometimes make intentional mistakes so the students can see the consequences of an incorrect identification.
The 500 line segments defined above together form a shape in the Cartesian plane that resembles a bird with open wings. Looking at the line segments on the wings of the bird causes an optical illusion and may trick the viewer into thinking that the segments are curved lines. Therefore, the shape can also be considered as an optical artwork.
