The other day when out walking I startled a small bird, who promptly flew up to a nearby tree, so I took advantage of the opportunity to get a BOB (Bird on Branch) shot:
It took me a little while to find which duck is, (I took the photo at our local Aquarium, in the Amazonian section)
It is a Ringed teal, one of the smallest duck in the world that lives in South America: Bolivia,Peru, Northern Brazil
