The story behind the Grey Heron was that I spotted this poor bird perched in a dead tree in a heavy rain storm and noticed that it would occasionally try to fly but was restrained. Thinking it was tangled in a cord I called the park ranger and together we safely rescued the poor bird, which had its feet tied together with rope. The only thing we could figure was that the bird had been captured and was made into a pet and had escaped. Anyway the rope was taken off its feet - there was no broken skin and the bird was safely released. Sad story with a happy ending
