Lunchtime For Eurasian Magpies

Eurasian magpie is a resident breeding bird throughout the northern part of the Eurasian continent. As the only bird which can pass the mirror self-recognition test, Eurasian magpie is known as one of the most intelligent animals.

Researchers applied a small yellow sticker to the throat of Eurasian magpie, where it could be seen by the bird only by using a mirror. The feel of the sticker on its throat did not seem to alarm the magpie. The bird was then given a mirror. However, when the bird caught a glimpse of itself in the mirror, it began to scratch at its throat, which is a clear indication that it recognized the image in the mirror as its own.

Dogs do not have the ability to recognize their own reflection in a mirror. They will always treat their reflection like another dog or just simply ignore it.
