Smart Crows and Dogs

University of Washington scientists carried out an experiment to explore whether crows can identify the face of someone who is a danger to them.

In the experiment the researchers donned rubber masks of cavemen to trap and then release the crows. Thereafter researchers walked along the college paths wearing the same caveman masks to observe how the flock of crows react.




They cawed and screeched, angrily flapped their wings and flicked their tail to warn of the danger. The researchers wore masks of Dick Cheney which elicited no response.




Dogs too displayed intelligence when they sense the appearance of dog catchers.



Dog catchers would park the van a distance from the vicinity and sneak up on the strays, as described in a poem by Cheryl Li.

The sound of tyres, an engine's hum
The dog catcher's van - they've come !
Run! Hide !
But alas, caught from the side
