Captive Goffin's cockatoos found to dunk hard bread to improve its texture

A pair of veterinary medicine researchers at Medical University of Vienna and University of Vienna‚ in Austria‚ has found that some captive Goffin's cockatoos prefer to dunk their hard bread before eating it‚ seemingly as a means to improve its texture. In their paper published in the journal Biology Letters‚ Jeroen Zewald and Alice Auersperg‚ describe their observations of the birds and their theories on why the birds dunk the bread.
