Brookfield Zoo has many Reticulated Giraffes which spend much of their time outside. The giraffe is the tallest animal and has elastic blood vessels that allow it to compensate when it raises or lowers it's head quickly.
Enjoy the photos of these animals. The giraffe is one of my favorites.
Thanks for stopping by. Come back tomorrow to see the baboon. If you would like to see more of my photography, visit my Artfire studio The Shutterbug Eye.
