Every year for the past 3 years, this couple comes to this puddle of dirty water across from our office to rest. They stay for a few weeks and go to wherever it is that ducks go to in the Spring time. The puddle starts to dry up and they're usually gone by the time it's completely dry.
We see them every morning on our way to work and sometimes basking in the sun (when it's sunny) and feeding them is fun. They're very friendly but cautious. I do hate the crows that swoop down to steal their treats!
