Study: Birds That Think Like Humans
New Wales.co.UK reports:
“Paignton Zoo spokesperson Phil Knowling said: ‘Animals rely on discrimination for survival – they need to recognise mates, predators and food.
They have to select from the vast amount of information in their environment. To do this they use a sorting strategy. Animals sort either in a multidimensional way – using more than one variable – or a unidimensional way – using just one variable.’
The results suggested hornbills tend to sort by one variable – colour. When the shapes and patterns differed, the birds chose symbols that were the same colour as the symbol that gave them the treat. This is the technique that most humans use.” See full article.
