Birds see shades of colour! #nature #rebootme #science #visual

A recent study has shown that Songbirds perceive colour just like we do.

The study led by Dr Eleanor Caves and Dr Patrick Green (Duke University), discovered that birds can categorize colours. They can identify shades of colours, perceiving the difference between reds and oranges.

Primates have previously been confirmed with the ability to perceive hues like humans but this ability is non birds is new.

The researchers studied female songbirds who were able to correctly flip a two coloured disc to reveal food and avoid single coloured discs with no food.

The study was developed with eight different parts of the spectrum with various colour shades. The birds performed best when the colour differences were at each end of the spectrum.
