Fernando Nottebohm has been interested in birdsong since early childhood. By 2001 he had spent thirty years at Rockefeller University in New York studying how birds learn to sing, concentrating on canaries who are capable of learning new songs each year. His interest has been to study birdsong as ‘a model for the brain’. He studied the brains of caged birds and birds in the wild. The birds that needed to forage and escape predators produced more neurons in the hippocampus, the part of the brain that is essential to memory.
