When you are working on your computer for long periods of time you should make a habit of looking away from the screen, preferably at things that are far away, and then close - switch back and forth a few times to give your eyes a bit of a break and a nice little stretch. Cats and children are good at reminding you to take frequent breaks, though sometimes the breaks are longer than intended.
These are some Black-Handed Spider Monkeys at the Calgary Zoo a few weeks ago. They were a lot of fun to watch and photograph. Monkeys are often one of my favorite exhibits at a zoo.
And these are some Bison from the same visit. The Calgary Zoo had a lot of baby animals - including a baby elephant but perhaps that will be a different post.
