WATCH: Perturbed Sandhill Crane Attacks It’s Own Reflection in a Glass Door

Cassy Rivers, 54, saw the crane stabbing at its own reflection in a glass door at Windemere Elementary School for ten minutes

This is the hilarious moment a bird-brained crane attacked its own reflection in a glass door.

Cassy Rivers, 54, was working at Windemere Elementary School in Florida earlier this month when she heard a strange banging noise coming from outside.

She suspected it may have been some animals having a scrap, but was gobsmacked when she discovered that the fight was actually between a sandhill crane and its own reflective image.

The sandhill crane prodded at its reflection with its distinctively long beak and caused several scratches on the glass

Cassy said: ‘I heard a banging noise and got scared it might be some animals fighting.

‘There was damage to the door, about 12 to 15 scratches.’

Footage taken by Cassy shows the plucky bird aggressively stabbing at the glass with its distinctively long beak.

It spends ten minutes bobbing its head both high and low and pecking in fascination as the reflection obviously mirrors its actions.

The crane, which was wedged between a strip of bushes and the long glass door, allows Cassy to get so close because it is totally engrossed in the reflection.

Cassy said: ‘He was outside for a good 10 minutes before I eventually drove him away.

‘The glass was ok. He was so involved with his reflection he didn’t care about me getting closer and closer.’

Coincidentally, this was not the first time Cassy had witnessed the phenomenon as she witnessed a similar reflection battle with a smaller crane earlier in the month.

Sandhill cranes are known for their energetic moves and are often seen stretching their wings and leaping into the air
