While in San Diego for BlogHer11, we spent the better part of a day at the San Diego Zoo (with Erin and her family!). We saw so many animals, but we spent a little extra time watching the flamingos. I had no idea the babies were grey! According to Natural Geographic, it is a diet of shrimp that turn flamingos pink. If there is a lack of shrimp in their diet, then they are a little more pale. Interesting!
