Did you know that the corvid-family of birds cache food for later — saving it in multiple spots for many months? They also watch other birds cache food and steal it–moving it for themselves. They are sneaky. They pay attention. This is interesting. There brain size to body ratio is relative to primates. They are social. We really enjoy watching them interact, eat and check things out.
Their ability to remember for long periods of time is fascinating. Some corvids have been observed recovering food caches up to 250 days after hiding them. Studies suggest this is due to their ability to use spatial memory ability. What is located next to what — such as many children do.

Maybe their abilities to cache food and to forward-think help them to survive when other birds are not doing so well. ((http://www.audubon.org/news/CBID_NYTimes.html))
