The Carter Mountain pronghorn herd contains approximately 7,000 animals—half which migrate 10–60 mi (16–97 km) west from common winter ranges in the Bighorn Basin to summer ranges near the Absaroka Range (fig. 29). During this migration, pronghorn must cross U.S. Highway 14 and Wyoming Highway 120. Most pronghorn summer in ranges west of Wyoming Highway 120 along the Greybull River, but some individuals summer in the South Fork Shoshone River drainage. A segment of the population gains nearly 6,000 ft (1,829 m) in elevation to summer on the high plateaus of the Absaroka Range and upper Greybull River and spend the summer months at 10,000–11,000 ft (3,048–3,353 m) above sea level in alpine meadows they share with...

The Clear Lake herd contains migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Instead, much of the herd displays a nomadic tendency, slowly migrating north, east, or south for the summer using various high use areas as they move. Therefore, annual ranges were modeled using year-round data to demarcate high use areas in lieu of modeling specific winter ranges. The areas adjacent to Clear Lake Reservoir were heavily used during winter by many of the collared animals. A few collared individuals persisted west of State Route 139 year-round, seemingly separated from the rest of the herd due to this highway barrier. However, some pronghorn cross this road near Cornell and...

The Jemez elk herd resides in the Jemez Mountains within the Valles Caldera National Preserve. This herd was originally included in Ungulate Migrations of the Western United States, Volume 2 (Kauffman and others, 2022), but has been updated for this volume owing to the acquisition of new data from 40 additional adult females. The Jemez elk are only partially migratory, with some residents remaining within the Valles Caldera year-round, while others exhibit two distinct seasonal movement patterns. The first movement pattern occurs during midwinter (January–February; arrows labeled 1) when numerous individuals move to the lower elevation slopes of the Valles Caldera, primarily southeast towards Bandelier National...

This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 1 (Kauffman et al. 2020) and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data can be viewed at: https://westernmigrations.net. Data in this archive can be downloaded two ways. To download...
Elk within the Jackson herd have been the focus of management for over a century. The herd, which numbers between 9,000 -13,000, winters in Jackson Hole. Most of the herd winters in the sagebrush basins and irrigated fields of the National Elk Refuge, with less than a quarter of the herd wintering in the Gros Ventre drainage to the east. Migrating animals travel an average one-way distance of 39 miles, with some migrating as far as 168 miles. The herd is partially migratory, containing both migrant and residents. In spring, the migrants move north on either side of Jackson Lake, into the eastern foothills of the Teton Range and into the upper drainages of the Snake River and the southern portion of Yellowstone National...
The Baggs Mule Deer Corridor was officially designated by the Wyoming Game and Fish Department (WGFD) in 2018 (fig. 24). The Baggs Herd is managed for approximately 19,000 animals, and the corridor is based on two wintering deer populations: a northern and southern segment. Animals in the north segment occupy a relatively small winter range along a pinyon-juniper ridge that runs along the east side of Highway 789. From there, deer migrate north and west to summer ranges on Atlantic Rim, the Sand Hills, and the head of Savery Creek. The southern segment occupies a larger sagebrush winter range on both sides of Highway 789, some of which extends into Colorado. These animals migrate north and west to summer ranges...
The Interstate 17 (I-17) elk herd primarily resides in Arizona’s GMU 6A and 11M south of Flagstaff. The population estimate for elk in GMU 6A was 6,500 in 2019. Their summer range consists of gentle topography with ponderosa pine forest and interspersed riparian-meadow habitat. Annually, the I-17 elk herd migrates an average of 24 miles to lower-elevation winter range dominated by pinyon-juniper habitat. This winter habitat is located along Oak Creek Canyon to the west and Wet Beaver Creek to the south. The I-17 elk herd faces high road mortality, averaging around 80 mortalities from vehicles per year (Gagnon et al 2013). Despite the high incidence of elk-vehicle collisions along I-17, road crossings are generally...
In 2008, 13 mule deer were GPS collared near the South Rim of the Grand Canyon to understand the impact of Arizona’s State Route 64 on mule deer movement. Unexpectedly, 4 individuals migrated over 50 miles to summer range near the San Francisco Peaks, north of Flagstaff, containing alpine, subalpine, and ponderosa pine habitats. The GPS collars dropped in 2009, but questions surrounding this long-distance migration remained. In June of 2019, the Arizona Game and Fish Department GPS collared 20 mule deer from the San Francisco Peaks herd on their summer range in Game Management Unit 7E/7W, where an estimated 5,300 mule deer reside. The primary challenges to mule deer in this migration corridor are related to navigating...
Interest in the movement of pronghorn south of Arizona’s Interstate 40 (I-40) began when telemetry data from 1999 – 2004 showed seasonal round-trip movements upwards of 100 miles. In 2018, high-resolution GPS location data confirmed persistence of this remarkable pronghorn migration. This herd resides primarily in Game Management Unit 8, which had a population estimate of 400 individuals in 2019. Unlike traditional summer-winter range dynamics, this pronghorn population uses a complex of several important seasonal ranges during their annual movements, which are connected by narrow corridors. The herd has high fidelity to these corridors, which elevates the importance of research and management efforts to conserve...

Mule deer in the Sheep Creek sub herd are part of the larger Area 6 herd that occupies portions of Elko, Lander, and Eureka counties. The primary winter range of this population is located along the eastern flank of the Sheep Creek Range and the west side of Boulder Valley. Most deer migrate approximately 30 miles from winter ranges in upper Boulder Creek and Antelope Creek drainages to summer ranges on the west side of the Tuscarora Mountains. However, some deer in this population migrate much farther – approximately 80 miles – and connect with mule deer that summer east of the Humboldt River. This deer herd faces several challenges, including migration routes that pass through increased mineral extraction activities...

The Area 7 mule deer population is one of the state’s largest deer herds with an estimated population of about 11,000 in 2019. This deer herd is highly important to Nevada from an economic and ecological perspective. It’s one of the longest distance deer migrations in the state of Nevada with some animals known to migrate over 120 miles during a single migration. A subset of this population, known as the “Pequop” herd, crosses a major highway (US highway 93) and an interstate (Interstate-80) twice annually during their seasonal migration. Several million dollars in wildlife crossing structures have been constructed to help these deer during their migration, yet they still face challenges to connectivity between...
Mule deer in the Platte Valley South population are part of the larger Platte Valley herd unit with an estimated population of 11,000 animals. These mule deer winter in the sagebrush canyons and basins near the Platte and Encampment Rivers, south of Saratoga, Wyoming (fig. 29). Most of these deer migrate southerly 20–70 mi (32–113 km) to portions of the Sierra Madre, Medicine Bow Mountains, and Park Range in northern Colorado and southern Wyoming. Some of these deer move as far south as Rabbit Ears Range and must negotiate numerous fences, highways, and residential development to complete their migrations. These data provide the location of migration routes for mule deer (Odocoileus hemionus) in the Platte Valley...
The Ryegrass mule deer population is part of the larger Sublette herd that winters in the northwest portion of the Green River Basin, west of the Green River and north of Cottonwood Creek (fig. 34). In severe winters, these deer may travel southeast to The Mesa, Ross Ridge, or Reardon Draw areas. The Ryegrass region supports approximately 1,500 to 2,000 deer that migrate northwest to summer ranges in the Wyoming Range and Salt River Range. Many of these deer must traverse U.S. Highway 189, where deer-vehicle collisions are problematic. This stretch of highway is a top priority for underpass installation to improve both wildlife permeability and motorist safety. These data provide the location of migration routes...
Mule deer within the South Wind River herd make short- and medium-distance migrations from the foothills near Lander, Wyoming, into the Wind River Range and around its southern flanks (fig. 31). The longest migration in this herd is a 75-mile (121-km) route originating south of Lander near Twin Creek. Deer following this long-distance route traverse the southern edge of the Wind River Range and summer in the mountainous terrain at the head of the Big Sandy River. Some deer make medium-distance migrations, traveling 14–51 mi (23–82 km) northwest of Sweetwater Station to summer range in the northern Great Divide Basin. Meanwhile, other deer in this population make short- and medium-distance migrations of 7–59 mi (11–95...
Mule deer in the northern Wyoming Range population use winter ranges in the area between Big Piney and LaBarge. During spring, these deer generally move northwesterly to high-elevation summer ranges in the Salt River and Wyoming Ranges. Interchange with deer in the Sublette herd unit has been documented, with some individuals migrating northwest into Upper Green River drainages. At least one individual migrated 85 mi (137 km) north and summered north of the town of Jackson. Challenges for Wyoming Range mule deer include energy development on winter ranges, vehicle collisions on U.S. Highway 189 between LaBarge and Big Piney, severe winters leading to high episodic mortality, and disease. These data provide the location...

This dataset consists of one table with a record (row) for each goose location and columns containing location information and covariates. The dataset was used in an analysis of altitude selection and flight propensity in an accompanying paper (Weiser et al. 2024) and is being provided here to allow replication of that analysis. Goose locations (latitude, longitude, and altitude) were collected with GPS tags and represent three subspecies: Pacific Greater White-fronted Goose, Tule Greater White-fronted Goose, and Lesser Snow Goose. Covariates include weather information from ERA5 (Hersbach et al. 2022). In addition to the "used" locations (altitudes at which birds were recorded), the dataset also includes "available"...

These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps in the Baja California Peninsula, Mexico. Data include species observation details such as observers, dates, location, and number of individuals seen. Included are data from four camps along the the Baja California Peninsula, Mexico ("San Quintin", "Ojo de Liebre", "San Ignacio", and "Santa Rosalia") during the winter field seasons: 1990-2006.
The Egg Lake Rocky Mountain elk (Cervus canadensis nelsoni) sub-herd range extends northeast from the town of McCloud around Ash Creek to the Big Valley Mountains and as far east as Highway 139 near the community of Hackamore. During the winter, this sub-herd primarily resides to the east of Big Valley Mountains near Egg Lake in Modoc County, California. They migrate east to private timberlands and spend the spring and summer just outside of McCloud, California. Topography of this area is relatively flat, but gradually transitions to steeper slopes around creeks, and typical habitat includes Ponderosa pine (Pinus ponderosa), Sierran mixed conifer, and montane hardwood conifer forests. Another sub-herd is known to...
The Paunsaugunt Plateau in southern Utah is home to around 5,200 mule deer (Odocoileus hemionus). Ongoing research by the Utah DWR has continued to shape our understanding of their annual migration. In contrast to the Volume 1 report (Kauffman et al. 2020), the Paunsaugunt Herd in this Volume includes the addition of 25 individual mule deer, 127 migrations, and 161 winter range sequences. Beginning in early October the mule deer migrate south an average of 36 mi (58 km) to winter range along the Utah-Arizona border. Approximately 20–30 percent of the Paunsaugunt Plateau herd reside in northern Arizona during the winter, sharing winter range also used by deer from Arizona’s Kaibab Plateau herd. Beginning around mid-April,...
The Jawbone Ridge mule deer (Odocoileus hemionus) herd is a sub-herd of the Tuolumne herd, which migrate to the Jawbone Ridge flats in the winter in Tuolumne, Mariposa, and Alpine Counties. Additionally, a small sample of deer were captured from the Yosemite herd to determine herd overlap. GPS collars were normally set to take a location every 7 hours, and emit a signal Monday through Friday, 9am to 5pm. Some GPS collars were set to take a location fix every hour during periods of time when deer were thought to be migrating (May and November). The most important portion of the winter range is the Jawbone ridge flats, situated at an elevation of 4,000 feet. Deer migrate from here east into the high Sierra Nevada...
