Abstract
The huge cypress trees overhung the Rio Corona with their giant arms. Nearly touching the water in places, they shaded the river from the harsh Mexican sun. Traveling down an obviously worn path, I arrived at the river's edge only to capture a parting glimpse of several wild muscovy ducks. Despite being the size of a goose they maneuvered the the turns in the river like falcons. Bird watching generally isn't very productive during the mid-day hours so I spent more time looking for aquatic life than arboreal forms. A rustling in the trees, however, warranted attention and resulted in my introduction to the red-billed pigeon (Columba flauirostris).
