Hummingbirds have superb memories of last meals

OTTAWA (AFP) - The tiny Rufous hummingbird is able to recall where and when it last dined on the sweet nectar of flowers, according to new research, proving bird brains are smarter than first thought.
The study found the bird, with a brain no bigger than a grain of rice and which feeds on hundreds of flowers each day, could pinpoint the location of flowers it had visited and when the bit of nectar in each would be replenished.
Such episodic memory was previously thought to be exclusive to humans.
"This shows that animals have better memories than we thought and that you don't need a large brain for some complex tasks," study co-author Andrew Hurly told AFP.
"This is an animal whose brain is 7,000 times smaller than ours. It's pretty remarkable that they can combine space information and time intervals together and update them constantly throughout the day. It's a very sophisticated thing to do," the biology professor at the University of Lethbridge in western Canada said.
