The Wilson’s Snipe (Gallinago delicata) is a medium-sized shorebird that breeds across Canada and the northern United States. It is a cryptically colored bird that relies on camouflage and concealment to avoid predators. But is the Wilson’s Snipe actually a rare bird?
Quick Answer
Overall, the Wilson’s Snipe is not considered a rare bird. According to the International Union for Conservation of Nature (IUCN), it is classified as a species of “Least Concern.” Its global population is estimated to be around 2.8 million individuals. While some local populations have declined, its overall numbers remain relatively robust across its widespread breeding and wintering range in North America.
Wilson’s Snipe Identification
Before diving deeper into the rarity question, it’s helpful to understand how to identify a Wilson’s Snipe. Some key identification features include:
- Medium-sized shorebird, about 10.5 inches (27 cm) in length
- Long straight bill, about 2.8 inches (7 cm) in length
- Cryptic brown, black, and white striped plumage
- Distinctive white outer tail feathers
- When flushed, makes a characteristic “winnowing” sound with its outer tail feathers
The Wilson’s Snipe is very similar in appearance to the more widespread Common Snipe. The Wilson’s has narrower and more defined striping compared to the Common. It also has a slightly shorter bill and darker legs. Range can help distinguish the two – Wilson’s breeds mostly in North America, while Common breeds across Eurasia.
Breeding Range and Habitat
Wilson’s Snipes breed predominantly across Canada, Alaska, and the northern half of the lower 48 United States. Their breeding habitat consists of wet meadows, marshes, bogs, swamps, and the muddy shorelines of ponds and rivers. They prefer areas with saturated soils and lots of low, dense vegetation to provide cover and camouflage while nesting and feeding.

Wintering Range
During winter, Wilson’s Snipes migrate predominantly to the southern half of the United States, Mexico, and scattered areas further south in Central America and northern South America. Their winter habitat includes freshwater and tidal marshes, wet fields, flooded agricultural lands, and along muddy shorelines.
Population and Conservation Status
According to the IUCN Red List, the global population of Wilson’s Snipe is estimated to be around 2.8 million individuals. Based on this population size, their extensive range, and the lack of evidence of rapid declines, the IUCN lists Wilson’s Snipe as a species of “Least Concern.”
However, some local populations have declined significantly, particularly in southern Canada, the northeastern U.S., California, and portions of Mexico. These localized declines are driven by habitat loss, primarily the draining of wetlands for agriculture and development. But from a global perspective, the species as a whole appears relatively stable and not at imminent risk of extinction.
Here is a table summarizing the population and conservation status of Wilson’s Snipe:
Population Estimate | Population Trend | IUCN Red List Status |
---|---|---|
2.8 million | Declining locally, stable globally | Least Concern |
Rarity in the United States
Within the United States, the Wilson’s Snipe is included on some state lists of “Species of Special Concern” or other designations for populations that are rare, declining, or vulnerable within that state. These states include:
- Connecticut – Species of Special Concern
- Massachusetts – Species of Special Concern
- New York – Species of Greatest Conservation Need
- Vermont – Species of Greatest Conservation Need
- New Jersey – Special Concern species
- Pennsylvania – Endangered/Protected species
However, the Wilson’s Snipe remains relatively common and widespread across Canada, Alaska, and the northern U.S. from the Rockies to the west coast. So while rare and declining in portions of its range, particularly the northeastern U.S., it is still a fairly common species across substantial parts of North America.
Reasons for Rarity
In areas where Wilson’s Snipe have become rare and populations have declined, habitat loss is the primary cause. The draining and filling of wetlands for development and agriculture has greatly reduced suitable habitat for snipes in some regions. For example, it is estimated over 50% of wetlands in California’s Central Valley have been lost since 1900.
Other threats and pressures facing Wilson’s Snipe include:
- Climate change – drying out of breeding habitat
- Overgrazing – degradation of wet meadows
- Predation
- Hunting (where permitted)
- Pesticides – may reduce prey numbers
Protecting remaining wetlands throughout their range and restoring drained or degraded wetlands will benefit Wilson’s Snipe populations. Sustainable grazing practices can also help conserve suitable habitat.
Comparison to Other Snipe Species
Compared to other snipe species worldwide, Wilson’s Snipe remains relatively common and not considered globally threatened. Here is a brief comparison with other snipe species and their conservation status:
- Common Snipe – Least Concern, stable/increasing global population estimate around 13 million.
- Pin-tailed Snipe – Least Concern, stable population estimate around 310,000-620,000.
- Swinhoe’s Snipe – Least Concern, decreasing population around 50,000-100,000.
- Great Snipe – Near Threatened, decreasing population around 101,000-200,000.
- New Guinea Snipe – Data Deficient, very limited population data.
- Solomon’s Snipe – Near Threatened, decreasing population with around 10,000-25,000 left.
- African Painted Snipe – Endangered, decreasing population estimated around 5,000-15,000.
So among the world’s approximately 30 snipe species, the Wilson’s Snipe remains one of the more common and stable populations globally. While facing some localized declines, its overall population is robust compared to many other snipe species with smaller and more threatened populations.
Snipe Identification Tips
Since snipes are cryptic, secretive birds that inhabit dense wetland vegetation, they can be tricky to spot and identify. Here are some tips to help locate and identify Wilson’s Snipes and other snipe species:
- Listen for their distinctive “winnowing” display flights in spring. Wilson’s make a sharp, piercing two-note call.
- Scan muddy wetland edges and marshy meadows.
- Look for quick, darting movements low in vegetation. May see just the top of their head moving.
- Use pishing sounds and squeaking to try flushing snipes from hiding spots.
- Note the overall size, bill length, plumage patterns, and tail feathers when seen.
- Pay attention to range – Eurasian species occur only accidentally in North America.
With patience and practice, birders can become better at finding these well-camouflaged wetland denizens. Just be prepared to get your boots muddy in the process!
Spotting Scope Recommendations
A quality spotting scope is extremely helpful for observing Wilson’s Snipes and other shorebirds. Here are some top-rated spotting scopes to consider for snipe identification and birding:
Spotting Scope | Key Features |
---|---|
Vortex Razor HD 27-60×85 | Excellent optics, wide zoom range for scanning and details |
Celestron Regal M2 65ED | Lightweight, quality ED glass, good balance of portability and magnification |
Zeiss Victory Harpia 85 | Top of the line optics and image quality, 85mm for low light performance |
Nikon ED50 80x | Reasonable price, quality ED glass, 45 degree viewing angle |
Leica APO-Televid 82 | Exquisite optics and build quality, large 82mm objective lens |
Be sure to use a sturdy tripod with the spotting scope, as a high magnification image will be impossible to stabilize by hand. For outright optical performance, the expensive Leica and Zeiss models are hard to beat, but the Vortex and Celestron offerings provide excellent quality at a more reasonable price point.

With some dedicated study and time in the field, birders can master identifying tricky shorebirds including snipes. Wilson’s Snipe with its distinctive winnowing display flight offers a great starting point for connecting with these wetland birds.
Conclusion
In summary, while the Wilson’s Snipe has experienced declines in portions of its range and could warrant more conservation attention locally, from a global perspective it remains a relatively common and stable species. Its sizable total population and expansive breeding distribution across Canada and the northern U.S. means it is not currently considered globally threatened or endangered. However, habitat protections and wetland restoration efforts focused on areas with declining snipe populations could help ensure this fascinating shorebird remains common well into the future.
