Hi everyone. I am an undergraduate student doing work on cockatoo play behaviour. I will be working with 12 hand-reared individuals in a lab but will have very limited time so I don't think I will be able to do pilot testing. So I would like to know if parrot owners (specifically Goffin cockatoos if possible) could let me know what their parrots' attention span is like, playing with a single simple toy (eg. a parrot safe wooden cube). I need to have a general idea of how long it will interest them for and how much that varies between individuals. If you could provide videos of the bird playing so I can look at the behavioural patterns that would be awesome too. Thanks!
