The tabular dataset is a compilation of all historic observations of whooping crane locations up through 1941. Most of the records were obtained from Robert Porter Allen's 1952 report, "The Whooping Crane"; an additional 73 records were added from records found since 1952. Records include source (Allen 1952 [The Whooping Crane, Audubon]or other), location name, county, state or province, country (Canada, US, Mexico), estimated latitude and longitude, year, month, day, life stage (breeding, summering, wintering, migration, unknown), season (spring, summer, fall, winter), observer's name, and logical indicators of nesting, specimen taken, observer identified, or if captive bird. Completeness of each record is variable....
1. Wind power plants represent a risk of bird mortality, but the effects are still poorly quantified. We measured bird mortality, analysed the factors that led birds to fly close to turbines, and proposed mitigation measures at two wind farms installed in the Straits of Gibraltar, one of the most important migration bottlenecks between Europe and Africa. 2. Bird corpses were surveyed along turbine lines and an associated power line to estimate mortality rates. The behaviour of birds observed within 250 m of turbines was also recorded as a putative indicator of risk. The effects of location, weather and flight behaviour on risk situations (passes within 5 m of turbines) were analysed using generalized linear modelling...

Each year, plants and animals undergo certain life cycle events, such as breeding or flowering. These phenological events are linked to weather and climate, and as temperature and precipitation patterns have changed, some spring events are occurring earlier. These changes in plant phenology can have cascading effects on wildlife such as elk, moose, and mule deer, which depend on plants for food. It’s thought that the quality of forage available in the spring could play a critical role for these big game species, which need to replenish energy depleted during the winter, in order to survive and successfully reproduce. Climate change will alter plant phenology, which in turn is likely to effect when, where, and for...
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...
The Paunsaugunt Plateau in southern Utah is home to a prolific mule deer herd numbering around 5,200 individuals in 2019. In early October, these mule deer begin their migration from the Plateau traveling south distances up to 78 miles to winter range in the Buckskin Mountains near the Utah-Arizona border. Approximately 20-30% of the Paunsaugunt Plateau herd reside in northern Arizona during the winter, sharing winter range also used by deer from the Kaibab Plateau herd. Beginning in late April, deer reverse their migration to summer range on the Plateau. The most significant challenge for these deer is US Highway 89 which bisects this migration corridor and winter range, where deer-vehicle collisions have historically...

Waterfowl are ecologically, culturally, and economically important and their annual and long-term distributions in North America can substantially impact ecological relationships and have economic impacts. In Mississippi, Arkansas and Louisiana alone, recent annual sales of Federal Duck Stamps equal $2.4 million. An intensive study in Mississippi estimated the annual total economic impact of waterfowl hunting in that state was $86.8 million. North American waterfowl number in the millions, use a diversity of aquatic and terrestrial foraging niches, and can feed at rates capable of depleting local food resources. In recent years, waterfowl appear to be wintering at more northern latitudes. Sustained northern...

It is produced for general visual reference and to aid users in generating various natural resource analyses and products. The shape files depict the known anadromous fish bearing lakes...
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 mule deer (Odocoileus hemionus) of the Jemez Springs herd winter in the southwestern Jemez Mountains, south and east of the town of Jemez Springs. The area has experienced two severe wildfires, the Las Conchas and Thompson Ridge fires, within the last decade, burning a total of 180,555 acres. The data used in this report was collected to examine the responses of mule deer to these wildfires and forest restoration treatments. The winter range is located among the foothills of the Jemez Mountains, consisting primarily of pinyon-juniper woodlands. Individuals migrated an average of 26.1 miles, either to the western edge of the Jemez Mountains, near Blue Bird Mesa, or to the Valles Caldera. The central migration...
The Rosa mule deer (Odocoileus hemionus) migrate an average of 45 miles from northwest New Mexico to southwest Colorado. Their winter range is located in the upper San Juan Basin, east of the Navajo Reservoir, and is dominated by pinyon juniper woodlands and sagebrush grasslands. The Rosa herd utilize three distinct areas as summer range: the lower elevation Valle Seco, consisting primarily of ponderosa pine woodland and big sagebrush shrubland, and the higher elevation North and South San Juan Mountains, consisting of ponderosa pine and aspen-mixed woodlands. The herd collectively migrate northeast from their winter range for around 12 miles before a second route branches off the main corridor, with these individuals...
The East Shasta Valley sub-herd of Rocky Mountain elk (Cervus canadensis nelsoni) spend most of their time on private ranchlands in Shasta Valley in the winter. This area offers patches of oak woodlands and grasslands on gentle slopes. In the spring, elk migrate to their summer range around Grass Lake, Bull Meadows, and Deer Mountain where the habitat is primarily characterized by mixed conifer timber stands of Ponderosa pine (Pinus ponderosa), lodgepole pine (Pinus contorta) and Douglas fir (Pseudotsuga menziesii). The meadows around Grass Lake seem especially important to this sub-herd, as neonatal calves have been documented in this area since at least 1984 (Fischer 1987). Some animals from this sub-herd migrate...
The Rainbow Valley mule deer (Odocoileus hemionus) reside in the expansive Sonoran Desert flat between the Sierra Estrella Mountains and the North Maricopa Mountains. The herd, which numbered 1,500 in 2017, is managed for hunting within Game Management Units (GMU) 39 and 40. The movements depicted in this report represent annual range for 3 mule deer which are part of a much larger research project along the Interstate 11 (I-11) Proposed Corridor Alternative. The research is being conducted by the Arizona Game and Fish Department (AZGFD), with funding from the U.S. Department of the Interior through Secretarial Order 3362. Although the Rainbow Valley mule deer are not migratory in the traditional sense, their annual...
The North of Interstate 40 (I-40) elk (Cervus canadensis) herd makes an annual migration throughout some of Arizona’s high elevation landscapes west of Flagstaff. The bulk of the herd resides in Arizona’s Game Management Unit (GMU) 7W during the summer and during the winter many migrate to GMU 10. The GMU 7W population had an estimate of 4,300 individuals in 2019, while the GMU 10 population had an estimate of 3,200. Like many elk in Arizona, only a portion of the herd is migratory. Summer range contains ponderosa pine forests and open prairies near Government Prairie and Sitgreaves Mountain. In the winter, the elk transition to gradually lower elevations and habitats dominated by pinyon-juniper woodlands. I-40...
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...

Understanding how routing modifications influence survival of juvenile salmon is complex because reach-specific survival and routing at key river junctions in the North Delta each have a different relationship with river flow. Therefore, to facilitate understanding of how routing modifications at key river junctions influence through-Delta survival, we developed this spreadsheet model to allow managers to explore the potential effects of modifying routing. The purpose is to provide a screening tool that allows managers to quickly run many different scenarios to understand how both routing and route-specific survival interact to affect overall survival through the Delta. This tool may be useful in narrowing the range...
Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/ele.12772/full): The Green Wave Hypothesis posits that herbivore migration manifests in response to waves of spring green-up (i.e. green-wave surfing). Nonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking. In a population of migratory mule deer (Odocoileus hemionus), 31% surfed plant phenology in spring as well as a theoretically perfect surfer, and 98% surfed better than random. Green-wave surfing varied among individuals and was unrelated to age or energetic state. Instead, the greenscape, which we define as the order, rate and duration of green-up along migratory routes,...
The winter range of the West Goose Lake Rocky Mountain elk (Cervus canadensis nelsoni) sub-herd is located north of Alturas and west of Highway 395 within the Devil’s Garden Ranger District of the Modoc National Forest. This area is characterized by juniper (Juniperus occidentalis) woodlands, and sagebrush flats with some stands of lodgepole (Pinus contorta) and ponderosa pine (Pinus ponderosa) throughout flat, rocky terrain. From this area, a portion of the herd migrates approximately 50 miles north into Oregon’s Fremont National Forest, habitat that primarily consists of lodgepole and ponderosa pine forests. Minimal barriers exist along this migration route since the corridor primarily occurs on land managed by...
The San Francisco Peaks elk (Cervus canadensis) herd comprises a migratory portion of the larger herd units in Arizona’s Game Management Units (GMU) 7 and 9. GMU 7 and 9 had a combined population estimate of 5,200 in 2019. These data were generated from two elk research projects by the Arizona Game & Fish Department: one to assess elk-vehicle collisions on Interstate 40 (Gagnon et al. 2012) and the other to evaluate aerial survey methods for elk abundance (Bristow et al. 2019). While many of the elk reside in the same general areas year-round, the migratory portion of this herd migrates an average of 42 miles between summer and winter range. Summer range, primarily in GMU 7, consists of high elevation open meadows...
