Abstract Eared Grebes (Podiceps nigricollis) in autumn make a postbreeding/molt migration from breeding areas in western North America to hypersaline lakes in the Great Basin. We studied their biology in 2001–2006 during this phase of the annual migration near Green River, Wyoming, USA where migrants en route to Great Salt Lake, Utah land on industrial ponds. Most evidently originate in the Prairie Pothole Region of North Dakota. The main movement extends from late July to mid-October. Migrants… Expand
Spring Downings Clarify the Migration Biology of Eared Grebes (Podiceps nigricollis)
Abstract. Eared Grebes (Podiceps nigricollis) staging at the Great Salt Lake, Utah, USA, sometimes experience weather-induced downings where many individuals are killed. Downings of Eared GrebesExpand
Population Fluctuations and Distribution of Staging Eared Grebes (Podiceps Nigricollis) in North America
TLDR
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
Late‐moulting Black‐necked Grebes Podiceps nigricollis show greater body mass in the face of failing food supply
TLDR
This is the first study to support the hypothesis that individual waterbirds adopt different strategies in body mass accumulation according to timing of moult: early-season grebes were able to acquire an excess of energy over expenditure and accumulate fat stores while moulting. Expand
Female-Biased Sex Ratio in Moulting Black-Necked Grebes Podiceps nigricollis in Southern Spain
TLDR
A unique case of a strongly biased sex ratio in a moult-migrating bird species with biparental care is reported, in which adult females were significantly more abundant than adult males in all 7 years (1.6–4.2 females per male). Expand
Waterbird mortality in hypersaline environments: the Wyoming trona ponds
TLDR
The mortality of Eared Grebes at trona ponds is attributed to complications of salt encrustation, notably impaired thermoregulation and other purported cases of sodium toxicity involving encrusted birds at industrial ponds or hypersaline situations may have a similar etiology. Expand
Waterfowl habitat use and selection during the remigial moult period in the northern hemisphere
TLDR
Factors affecting site selection amongst waterfowl (Anatidae) during the flightless remigial moult are reviewed, emphasising the roles of predation and food supply (especially protein and energy) and the role of habitat selection is emphasised. Expand
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
Observations on Zugunruhe in Spring Migrating Eared Grebes
TLDR
Directed mass pattering of Eared Grebes may contribute to synchronization of the onward migration of the birds involved. Expand
Sexual dimorphism and sex determination in Black-necked Grebes Podiceps nigricollis: on the need to account for geographical variation in morphology and sex ratio
TLDR
The sex of Black-necked Grebes Podiceps nigricollis in Spain can be determined successfully using a locally derived discriminant function analysis (DFA) but a function derived from a North American population was not successful, illustrating the need for caution when applying discriminant functions developed in one bird population to individuals elsewhere.

West Nile Virus Transmission in Winter: The 2013 Great Salt Lake Bald Eagle and Eared Grebes Mortality Event
TLDR
An unusually large wild bird mortality event involving between 15,000-20,000 Eared Grebes and over 40 Bald Eagles around the Great Salt Lake, Utah, in November-December 2013 is reported, which is the largest single raptor mortality event since WNV became endemic in the USA. Expand

Observations on the Fall Migration of Eared Grebes, Based on Evidence from a Mass Downing in Utah
TLDR
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.

Conspecific Collisions Can Precipitate Mortality in Migrating Eared Grebes
TLDR
The high mortality at IPP can be traced to traffic congestion, which resulted when thousands of migrants disoriented by the snowstorm homed in on the brilliant lights of the plant which can be seen for miles, because even a hard landing on a pond is more survivable than flying into frozen ground.

Flying the gantlet : Population characteristics, sampling bias, and migration routes of eared grebes downed in the Utah Desert
TLDR
Examination of carcasses found important differences in sex ratios between two samples derived from the same flight, which indicates that assumptions regarding unbiased sampling require testing, and the possibility that regular catastrophic events in central and southern Utah have influenced the evolution of migration routes in Eared Grebes deserves further consideration.

Stratification, sulfide, worms, and decline of the Eared Grebe (Podiceps nigricollis) at the Salton Sea, California
TLDR
It is proposed that a worsening food supply is causing the decline of the Eared Grebe population and that starvation may be a major cause of the unexplained mortalities. Expand
Digestive tract function in the long-distance migratory garden warbler, Sylvia borin
TLDR
It is concluded that the garden warbler adapts to long-distance migration without feeding by rapidly reducing the size of its digestive tract during migration in order to save weight and energy, and possibly also to supply part of the fuel and protein required for the flight. Expand

Temperature Regulation and the Constraints of Climate in the Eared Grebe
TLDR
It is concluded that Eared Grebes live most of the year under thermoneutral conditions and that food availability, not temperature extremes, determines the timing of their winter migration. Expand
Cyclical changes in body composition in the annual cycle and migration of the Eared Grebe Podiceps nigricollis
TLDR
Several lines of evidence suggest that grebes attain a specific (optimal?) body composition prior to migrating, and these reductions in leg and visceral mass, which occur in all seasons, reduce flight costs by minimizing wing loading and enhancing flight speed. Expand
