Birds

Records of bird sightings have been kept in Yellowstone since its establishment in 1872. These records document nearly 300 species of birds to date, including raptors, songbirds, shorebirds, and waterfowl. Approximately 150 species nest in the park. The variation in elevation and broad array of habitat types found within Yellowstone contribute to the relatively high diversity. Many of the birds are migratory species. There are currently no federally listed bird species in Yellowstone National Park.

The Yellowstone National Park bird program monitors a small portion of its breeding bird species to gather information like reproduction, abundance, and habitat use. Data is collected on multiple species from a wide variety of taxonomic groups, and has been maintained for 25 or more years for several species. Long-term monitoring efforts help inform park staff of potential shifts in ecosystem function, e.g., climate change effects, for Yellowstone’s bird community and may guide future conservation of the park’s birds and their habitats.

 
 

Climate Change

The timing of the availability of food sources for birds may change with rising temperatures and changing weather patterns. Birds are sensitive to shifts in seasonal weather patterns and show a relatively rapid response to these fluctuations. For example, climate change has been shown to influence migration patterns, population size and distribution, the timing of reproduction, and nesting success for birds. Through monitoring, birds can be used as environmental health indicators to help managers detect changes in ecosystem function so that appropriate management action can be taken, if necessary.

The Yellowstone bird program monitors the arrival of species to the park, the timing of nest initiation, and fledging for several raptor species, which may be useful in observing the effects of climate change in Yellowstone.

 

Breeding Bird Surveys

Breeding bird surveys are a nationwide monitoring effort coordinated by the US Geological Survey and the Canadian Wildlife Service’s Research Center. Since the 1980s, Yellowstone National Park has participated in these long-term surveys conducted throughout North America. The surveys are road-based with the registered observer recording all birds seen and heard within a quarter mile radius with points occurring every half mile. The surveys are conducted in June, during the height of the songbird breeding season. Yellowstone has three routes: Mammoth area, Northeast Entrance area (Tower Junction to Round Prairie), and the interior (Dunraven Pass through Hayden Valley and Yellowstone Lake).

In 2015, surveyors detected 2,730 individuals of 78 species. The Yellowstone route (Dunraven Pass to Mary Bay) and the Northeast entrance to tower route had the highest diversity and number of individuals. with about 3.5 times the number of individuals. Large flocks of Canada geese along the Yellowstone River accounted for 63% of all observations along the interior route. Canada goose numbers were relatively stable from 1987 to 2010, after which they increased substantially for unknown reasons.

 

Number in Yellowstone

  • 285 documented species
  • Approximately 150 species nest in the park.

Species of Concern

  • Trumpeter swan
  • Golden eagle
  • Common loons

Current Management

The Yellowstone National Park bird program monitors the park’s bird species, including species of concern. The program’s core activities are monitoring raptors (bald eagles, ospreys, peregrine falcons, golden eagles), wetland birds, and passerine/near passerine birds (songbirds and woodpeckers).

 

Raptors

The park supports 19 breeding raptor species. Additional species use the Yellowstone landscape during migrations and seasonal movements. The bird program monitors bald eagles, ospreys, and peregrine falcons. Bald eagles and peregrine falcons were previously listed as endangered and threatened species and their monitoring is required by law. The osprey is monitored because a food source, the cutthroat trout, declined in Yellowstone Lake. Other species that occur in the park such as golden eagles and Swainson’s hawks are of growing conservation concern throughout their ranges in the United States.

Wetland Birds

Approximately 30% of the bird species that breed in Yellowstone depend on wetlands. Scientists are concerned about these species because wetlands are expected to diminish as global and local temperatures increase. They are monitoring the trumpeter swan, common loon, and colonial nesting species, like the double-crested cormorant and American white pelican. Yellowstone has years of data about the rate and success of nesting for some of these species, but little information about changes in the timing of nesting activity, which is an indicator of climate change.

Colonial Nesting Birds

Colonial nesting birds—pelicans, gulls, and cormorants—primarily nest on the Molly Islands.

Loons in Yellowstone are some of the southern most breeding populations.

Trumpeter Swan

Trumpeter swans are the largest wild waterfowl in North America.

 

Songbirds and Woodpeckers

Songbirds and woodpeckers, or passerine and near passerine species, comprise the majority of bird species in Yellowstone National Park. They are monitored through the willow–bird study, the breeding bird survey, and the forest burn survey.

Birding Locations

Good locations depend on what kind of birds you want to see, the time of day you are looking, and your location in the park. In general, riparian areas and wetlands, especially those with shrubby willows, aspen, and cottonwoods attract the greatest diversity and abundance of birds.

Hayden Valley is one of the best places to view water birds and birds of prey. Shorebirds feed in the mud flats at Alum Creek. Sandhill cranes often nest in the valley. Ducks, geese, and American white pelicans cruise the river. Bald eagles and osprey hunt for fish along the river; northern harriers fly low looking for rodents in the grasses. Great gray owls are sometimes seen searching the meadows for food (these birds are sensitive to human disturbance). Blacktail Pond and Floating Island Lake, between Mammoth and Tower Junction, and the Madison River west of Madison Junction are also good places to look for birds.

Many birds, such as American robins and common ravens, are found throughout the park. Other species live in specific habitats. For example, belted kingfishers are found near rivers and streams while Steller’s jays are found in moist coniferous forests.

Spring is a good time to look for birds. Migration brings many birds back to the park from their winter journeys south; other birds are passing through to more northern nesting areas. Songbirds are singing to establish and defend their territories; and many ducks are in their colorful breeding plumages, which makes identification easier.

Watch for birds on early morning walks from mid-May through early July. At all times, but especially during the nesting season, birds should be viewed from a distance. Getting too close can stress a bird (as it can any animal) and sometimes cause the bird to abandon its nest.

Most birds migrate to lower elevations and more southern latitudes beginning in August. At the same time, other birds pass through Yellowstone. Hawk-watching can be especially rewarding in Hayden Valley late August through early October. In early November, look for tundra swans on the water.

Birds that stay in Yellowstone year-round include the common raven, Canada goose, trumpeter swan, dusky grouse (formerly blue grouse), gray jay, red-breasted nuthatch, American dipper, and mountain chickadee. A few species, such as common goldeneyes, bohemian waxwings, and rough-legged hawks migrate here for the winter.

Visitors may report sightings with a wildlife sighting form and at visitor centers.
