There’s a reason she's called Einstein. This African Grey parrot has an extensive vocabulary and can replicate everything, from humans to animals, from sirens to microwaves and telephones. There’s a reason why the African grey is often considered the poster bird for parrot intelligence … not only is this bird inclined to amass large vocabularies, African greys have also demonstrated an aptitude for recognizing the meaning of words and phrases, recognizing and identifying objects, colors, and shapes and also understanding the concepts of same and different. Experiments proved they can also count. Some scientists believe the parrots' intelligence level is somewhere between a 3-4 year old child's.
We have been following Einstein for a few years and understand she now has a large following. I am always interested in how the intelligence of other species is evolving and how self aware they are. We are not the only species evolving and adapting. It's just not so obvious among other mammals or birds.
