Here are two birds that are a challenge to photograph. Greater Flamingos are always moving, feeding, or tucked into a resting pose. We saw three at Charca but there are many larger colonies in souther Spain.

Little Grebes are tiny, always moving, and constantly diving.

So, a trivia fact: flamingos weigh 2-4 kg and grebes weigh about 110 g so the Little Grebe is around 1/25th the size of the big bird. They are both wonderful to watch.
