ABSTRACT Great Salt Lake (GSL) is a critical migratory stopover location for Eared Grebes (Podiceps nigricollis), but the factors influencing the timing of their fall migration have not previously been investigated. We used archived Doppler radar data to visualize the nocturnal departures of Eared Grebes from GSL over 16 years, from 1999–2015. We used generalized linear models (GLMs) to examine interannual variability in the timing of migration of Eared Grebes in relation to prey availability… Expand
Factors influencing fall departure phenology in migratory birds that bred in northeastern North America
ABSTRACT The phenology of migrating birds is shifting with climate change. For instance, short-distance migrants wintering in temperate regions tend to delay their migration in fall during spells ofExpand

Waterbird Migration through a Saline Wetland in the Western Nevada Desert, USA
Abstract. A great variety of waterbirds migrate across western Nevada, where places to rest or refuel are nearly non-existent. One exception is a little-known industrial pond complex at the AlbemarleExpand
Great Salt Lake Shorebirds, Their Habitats, and Food Base
Every year millions of shorebirds representing 42 species congregate on Great Salt Lake (GSL). It is one of the largest concentrations of shorebirds on Earth, and yet, compared to waterfowl andExpand
Weather and eared grebe winter migration near the Great Salt Lake, Utah
In one case, it is demonstrated that an extended, nonstop flight was initiated of the departing eared grebes to northern Mexico and atmospheric conditions during the largest migration event observed are presented and discussed. Expand
Great Salt Lake Biology: A Terminal Lake in a Time of Change
Great Salt Lake (GSL) covers 5500 km (2100 mi) at its unimpacted elevation and is the eighth largest saline lake in the world. Its highly productive food web supports millions of migratory birds andExpand
A salt lake under stress: Relationships among birds, water levels, and invertebrates at a Great Basin saline lake
Abstract Saline lakes are threatened globally and provide critical habitat for a diverse array of migratory and breeding waterbirds. The ability of large numbers of waterbirds to profitably useExpand
Invertebrates and Phytoplankton of Great Salt Lake: Is Salinity the Driving Factor?
Great Salt Lake (GSL) is a hypersaline terminal lake and has varied historically in salinity from 6 to 28%. Because the lake’s salinity is much greater than in marine environments (~3.5%), salinityExpand
Aquatic Invertebrate Community Resilience and Recovery in Response to a Supra-Seasonal Drought in an Ecologically Important Naturally Saline Lake
Climate induced drought is a prominent threat to natural saline aquatic ecosystems by modifying their hydrology and salinity, which impacts the biodiversity of these ecosystems. Lake Nyamithi is aExpand
A summary of bird mortality at photovoltaic utility scale solar facilities in the Southwestern U.S.
It is found that a cause of mortality could not be determined for approximately 61% of intact carcasses, and that approximately 54% of all carcasses were feather spots, introducing uncertainty into the interpretation of the fatality estimates. Expand


Population Fluctuations and Distribution of Staging Eared Grebes (Podiceps Nigricollis) in North America
Populations changed on GSL and Mono Lake in synchrony, indicating population regulation is likely occurring at wintering, not staging, areas and is influenced by El Nino effects. Expand
Energy Budgets for Eared Grebes on the Great Salt Lake and Implications for Harvest of Brine Shrimp
Daily energy requirements of eared grebes are determined so that regulations governing brine shrimp cyst harvest would better reflect foraging needs of grebes. Expand
Observations on the Fall Migration of Eared Grebes, Based on Evidence from a Mass Downing in Utah
The data from this downing provided an opportunity to test and extend some earlier findings or inferences about the differential migration of age classes, duration of the flight to wintering areas, physical condition of departing and arriving migrants, the size of pectoral muscles needed for flight, and the risks of mortality along the migratory routes.

Delayed autumn migration in northern European waterfowl
The results suggest that waterfowl to be a good indicator group for climate change, and how rapid phenological responses to climate change may be, are highlighted. Expand
Why do Eared Grebes Leave Hypersaline Lakes in Autumn?
Abstract Jehl (1988) observed that the departure of Eared Grebes Podiceps nigricollis from Mono Lake, California, a major fall staging area, did not occur in relation to time of year or weather butExpand
Role of Benthic Substrate in Waterbird Distribution on Great Salt Lake, Utah
Knowing the relationship between waterbird densities and substrate will help managers estimate avian populations on hypersaline lakes. Expand
Eared grebe diet on Great Salt Lake, Utah, and competition with the commercial harvest of brine shrimp cysts
Current monitoring and management of commercial harvest are sufficient to maintain yearly populations of adult brine shrimp to sustain eared grebes populations. Expand
Departure of migrating European robins, Erithacus rubecula, from a stopover site in relation to wind and rain
Abstract Migratory birds replenishing their fuel stores have to decide when to leave their stopover site for the next flight bout. We studied whether the decision to leave a stopover site depends onExpand
Energy content and digestibility of brine shrimp (Artemia franciscana) and other prey items of eared grebes (Podiceps nigricollis) on the Great Salt Lake, Utah
Brine shrimp cysts had a high-energy concentration, but had the lowest amount of true digestible energy (34% of dry mass and 51% of energy), which helps explain why grebes are rarely observed foraging on them. Expand
Rainfall-induced changes in food availability modify the spring departure programme of a migratory bird
Climatic warming has intensified selection for earlier reproduction in many organisms, but potential constraints imposed by climate change outside the breeding period have received little attention.Expand
