The Wilson’s Snipe and the Common Snipe are two closely related bird species that were recently recognized as separate species. While they share many similarities, there are a few key differences that set them apart.
One noticeable difference between the two species is the width of the white edge on the wings. In the Wilson’s Snipe, this white edge is narrower compared to the Common Snipe. This can be a useful field identification feature when observing these birds in flight.
Another distinguishing characteristic is the number of tail feathers. The Wilson’s Snipe typically has 16 tail feathers, whereas the Common Snipe has 14. This subtle difference in tail feather count can be challenging to observe in the field, but it is a reliable diagnostic feature for distinguishing between the two species.
In terms of overall appearance, both species have mottled brown plumage that provides excellent camouflage in their wetland habitats. They have long bills that are used to probe the mud for invertebrates, their main food source. The bills of both snipe species are flexible and sensitive, allowing them to detect prey beneath the surface.
While the physical differences between the Wilson’s Snipe and the Common Snipe are relatively subtle, they also have some variations in their behavior and distribution. The Wilson’s Snipe is primarily found in North America, breeding in wetland habitats across a large portion of the continent. In contrast, the Common Snipe has a much broader distribution, occurring in Europe, Asia, and parts of Africa.
In terms of behavior, both species are known for their distinctive “winnowing” display flights during the breeding season. This involves the male birds flying in a series of zigzag patterns while producing a distinctive sound by vibrating their tail feathers. This behavior is believed to be a form of courtship display, attracting females and establishing territory.
Personal experience: I have had the opportunity to observe both Wilson’s Snipe and Common Snipe during my birdwatching expeditions. While they can be challenging to differentiate in the field, paying attention to the width of the white wing edge and tail feather count can be helpful in distinguishing between the two species. Additionally, their behavior and vocalizations, such as the winnowing display, provide further clues to their identity.
To summarize, the Wilson’s Snipe and the Common Snipe are two closely related bird species that have recently been recognized as separate species. They share many similarities in appearance and behavior, but key differences include the width of the white wing edge and the number of tail feathers. The Wilson’s Snipe has a narrower white edge on the wings and typically has 16 tail feathers, while the Common Snipe has a wider white edge and 14 tail feathers. Their distribution also varies, with the Wilson’s Snipe primarily found in North America and the Common Snipe having a broader range across Europe, Asia, and parts of Africa.
