Color legend for Distribution Map
NOTE: The maps for birds represent the breeding status by state and province. In some jurisdictions, the subnational statuses for common species have not been assessed and the status is shown as not-assessed (SNR). In some jurisdictions, the subnational status refers to the status as a non-breeder; these errors will be corrected in future versions of these maps. A species is not shown in a jurisdiction if it is not known to breed in the jurisdiction or if it occurs only accidentally or casually in the jurisdiction. Thus, the species may occur in a jurisdiction as a seasonal non-breeding resident or as a migratory transient but this will not be indicated on these maps. See other maps on this web site that depict the Western Hemisphere ranges of these species at all seasons of the year.
Endemism: occurs (regularly, as a native taxon) in multiple nations

Ecology & Life History
Help
Reproduction Comments: Breeding begins mid-May in west to early June in east (Harrison 1978). Usually 4 eggs are incubated for 22-23 days; eggs incubated by female during day, by male at night. Young precocial, tended by both parents until just before fledging (early August on Mackenzie Delta).
Ecology Comments: NON-BREEDING: gregarious.
Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: Y
Mobility and Migration Comments: Northward migration mainly through Texas and Louisiana and interior North America; usually reaches Texas in April; arrives in Beaufort Sea area late May-early June. Gathers in large flocks on western shores of Hudson and James bays prior to southward migration (to Maritime Provinces and New England, then southward by sea to southern South America, possibly with a stop somewhere in northern South America). Nonbreeders at Tierra del Fuego apparently derive from breeding grounds in central Canadian Arctic (Morrison and Ross 1989). Begins migration from northwestern Canada early to mid-August.
Estuarine Habitat(s): Herbaceous wetland, Tidal flat/shore
Palustrine Habitat(s): Bog/fen, HERBACEOUS WETLAND, Riparian
Terrestrial Habitat(s): Cropland/hedgerow, Grassland/herbaceous, Sand/dune, Tundra
Habitat Comments: BREEDING: Nests on grassy tundra, near water. Bogs and marshes. Near coast or river. Nests on the ground in a sparsely lined depression, in or under edge of prostrate dwarf birch or on dry top of hummock in sedge marsh. NON-BREEDING: marshes, beaches, flooded fields, and tidal mudflats (AOU 1983); lake and pond shores, inlets.
Adult Food Habits: Invertivore
Immature Food Habits: Invertivore
Food Comments: Feeds on marine worms, mollusks, and crustaceans. Probes deeply into mud. During the nesting season eats many insects (e.g., flies, mosquitoes).
Adult Phenology: Diurnal
Immature Phenology: Diurnal

Group Name: Shorebirds

Use Class: Breeding
Subtype(s): Feeding Area, Breeding Site
Minimum Criteria for an Occurrence: Evidence of historical breeding, or current and likely recurring breeding, at a given location, minimally a reliable observation of one or more breeding pairs in appropriate habitat. Be cautious about creating EOs for observations that may represent single breeding events outside the normal breeding distribution.
Mapping Guidance: Breeding occurrences include nesting areas as well as foraging areas of nesting adults and broods. Because separations are based on nesting areas, the foraging areas of different occurrences may overlap if nesting birds are traveling to distant places to feed.
Separation Barriers: None.
Separation Distance for Unsuitable Habitat: 5 km
Separation Distance for Suitable Habitat: 5 km
Separation Justification: Separation distance pertains specifically to nesting areas, not to locations of dispersed foraging individuals. For example, nesting areas separated by a gap of more than 5 km are different occurrences, regardless of the foraging locations of individuals from those nesting areas.

The separation distance is an arbitrary value; it is impractical to attempt to delineate shorebird occurrences on the basis of dispersal patterns or metapopulation dynamics. Foraging ranges of some nesting shorebird species (see following) may suggest use of a larger separation distance, but this likely would result in occurrences that are too large and less effective for conservation planning.

Separation distance based on larger 'typical' breeding home ranges with diameters of 1.5 to 3 kilometers. Semipalmated Plovers have breeding home ranges up to 3 square kilometers, i.e. a diameter of just under 2 kilometers (Nol and Blanken 1999). Red-necked Phalaropes have a core home range of 1-3 hectares, but occasionally travel 1.5 kilometers to feed (Rubega et al. 2000). Stilt Sandpipers can forage up to 8 kilometers from nest (Jehl 1973). Mountain Plovers have an average home range of 56.6 hectares (Knopf 1996) but broods typically move 1-2 kilometers shortly after hatching (Knopf and Rupert 1996).

Territories: Common Snipe, 6.4-28.6 hectares (Mueller 1999); Long-billed Dowitcher, 100-300 meter diameter (Johnsgard 1981); golden-plovers, average 10-59 hectares (Johnson and Connors 1996); Long-billed Curlew, 6-20 hectares (Johnsgard 1981).

Nesting densities: Black-bellied Plover, 0.3-2.3 pairs per square kilometer (44 ha per pair at latter density; Hussell and Page 1976, Parmelee et al. 1967); Marbled Godwit, maximum density 1 pair/32 hectares (Stewart and Kantrud 1972).

Foraging distances: Greater and Lesser Yellowlegs, up to 13 kilometers from nest (Elphick and Tibbits 1998, Tibbits and Moskoff 1999).

Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 1.5 km
Inferred Minimum Extent Justification: Based on a smaller 'typical' home ranges (see Separation Justification).
Date: 25Mar2004
Author: Hammerson, G., and S. Cannings

Use Class: Migratory stopover
Subtype(s): Roost, Foraging concentration area
Minimum Criteria for an Occurrence: Evidence of recurring presence of migrating flocks (including historical); and potential recurring presence at a given location, minimally a reliable observation of 25 birds in appropriate habitat (minimum can be reduced in the case of rarer species). Occurrences should be locations where the species is resident for some time during the appropriate season; it is preferable to have observations documenting presence over at least 7 days annually. Be cautious about creating EOs for observations that may represent single events.
Separation Barriers: None.
Separation Distance for Unsuitable Habitat: 5 km
Separation Distance for Suitable Habitat: 5 km
Separation Justification: Separation distance somewhat arbitrary; set at 5 kilometers to define occurrences of managable size for conservation purposes. Occurrences defined primarily on the basis of areas supporting concentrations of foraging or roosting birds, rather than on the basis of distinct populations.
