The dwarf green kingfisher is the smallest bird among the kingfishers of America. The body length of an adult bird is about 13 centimeters, and the weight does not exceed 18 grams.
The dwarf green kingfisher differs from close species in its very small size and bright green coloration with a metallic sheen. It helps maintain balance in nature by eating small aquatic animals.
