Identifying duck breeds from photographs requires knowing what to look for in order to distinguish one species from another. Size, shape, color and habitat need to be taken into consideration.
Variations in head sizes and body shapes, subtle details in plumage patterns, as well as the lengths of the wings and tails, can help identify a species. Different species are drawn to different types of habitats, and photograph backgrounds may provide a clue.
Size considerations such as how big the head appears in relation to the body and how high the duck is floating in the water can help to identify a species. Head markings such as a brow or eye line or crests and cheek patches can also offer clues. Head shape, either round or elongated, should also be considered. The size, color and shape of a duck’s bill can yield important information as to species. Additionally, the length of the duck’s neck, rings and coloration and the way the neck is positioned and held can help in identification.
Websites such as Flyways.us offer comparative size charts that help to identify species. This website also hosts a wide variety of different species with detailed descriptions, species that are similar, photographs, videos and sound. Additionally, there are illustrations and photos of each species in flight with the typical flock patterns it forms.
