Sandhill cranes can be seen along roadways throughout the City of Port St. Lucie, as well as throughout the state. They seem oblivious to human affairs going on around them, like traffic on the roads, as they go about searching for food. The state of Florida has designated the sandhill crane a threatened species. This means that if one were to step out onto the roadway, motorists should come to a stop and wait until all birds are off the pavement. Their main diet consists of insects and small lizards or frogs, which is why they are often seen in swales alongside roads.
