I wish I know what you're thinking ... Posing for a Portrait

This male silverback lowland gorilla at Chicago's Regenstein Center for African Apes at Lincoln Park Zoo poses everytime he sees a camera. It's hilarious. Don't you wonder sometimes what he is thinking?

From the Lincoln Park Zoo website (lpzoo.org): The state-of-the-art Regenstein Center for Africa Apes, which opened in July 2004, is unlike any other in the country – maybe the world. Twenty-nine-thousand square feet of living space, indoors and out. Bamboo stands real and simulated. Dozens of trees and 5,000 feet of artificial vines for climbing. Skylights. Termite mounds for chimpanzee “fishing.” A waterfall. A moat. Heated logs. Fresh air. Sunshine.

A major element of the new building is the Lester E. Fisher Center for the Study and Conservation of Apes. The center engages zoo visitors, members and students in science and conservation initiatives through an integrated program of research, science education and the conservation of wild populations.

About the gorilla (from lpzoo.org)

Description
Largest of the living primates; males up to 6 feet tall and 400 pounds, females up to 5 feet and 200 pounds. Greater weights occur in captivity. Coat black to brown-gray, turning gray with age. Adult males with broad, silvery-white “saddle” on back, extending to rump and thighs. Small ears, nostrils bordered by broad ridges, which extend to the upper lip. Young have a white tuft of hair on the rump.

Range
Cameroon, Central African Republic, Gabon, Congo and Equatorial Guinea

Status
The gorilla is listed as endangered, and commercial trade of this species is prohibited by international law. Principal causes of population decline are habitat destruction and hunting. Poachers prize adult males and disrupt troops by killing leaders. Lincoln Park Zoo participates in the Gorilla Species Survival Plan® and is world-famous famous for its success in breeding captive western lowland gorillas.
