This is positively one of the oddest ducks that we have seen in our lives. We were out at the park, and they had a small area where a few ducks were being kept. We went closer only to realize that they were different from any other ducks that we had seen before. One of them in particular had found a feather on the ground (actually it looked like it was his own), and he kept moving around all over the place carrying this feather in his beak.
Every time we tried to get a little closer to him he would move away, so finally we decided to just sit around and watch them move around the place. We had been sitting there for close to half an hour when we noticed that this particular duck was coming closer and closer to us, and finally he stationed himself about 4 feet away from us. He never came closer, but that was good enough for us to get as many photographs as we needed.
Lesson learnt, – when interacting with birds and animals, let them come to you. Be patient, let them know that you are not there to harm them; once they realize this, they lose their fear, and will come closer than you expect them to.
