No. A landmark study in 1970 at Tulane University in New Orleans, USA, showed conclusively that chimpanzees recognize their own reflections.

Under sedation, a blob of non-toxic paint was applied to the chimps' faces. When they woke they were given mirrors and, seeing the paint, the chimps touched it and cleaned it off, demonstrating that thhey realized the image in the mirror was their own.

Similar studies have suggested that orangutans can also recognize their own reflections.
