Color in photo viewers

In a post about my favorite lizard, I noted that the same animal can appear in different colors in different photos. That's true even when using the same camera in the same light. (I still almost always shoot with the camera in full automatic mode.) The other day I noticed that the exact same photo can have a different color cast depending on the program used to view the picture.

In the left image, rocks have a tan cast. In the right, they're gray.
On the left, Windows Photo Viewer. On the right, Windows preview.

The photo is from January, and I can't say now which rendering is closest to what I saw. The picture in Paint and PaintShop Pro looks like the one on the right, so maybe those colors are "correct."

Columbus Zoo July 22

My visit was actually July 23, but "three" doesn't rhyme with "zoo."

The signage says common ostrich, but the website says blue-neck ostrich.

Saddle-billed storks dance.
At the Columbus Zoo, North America is adjacent to Heart of Africa, so it was no trouble to walk.

A cedar waxwing. This is one of my favorite birds because of its cool sunglasses and jaunty hairdo.

A scarlet tanager, in nonstandard plumage. These guys are supposed to be red all over with black wings. Females are yellowish.

Caterpillars on the bald eagle enclosure. I hadn't noticed these, but another visitor pointed them out, and the white ones were crawling all over the fencing.

A trumpeter swan takes a drink.
