The potential contribution of early spring feeding conditions in the Arctic to clutch size variation was examined in a population of Lesser Snow Geese Anser caerulescens caerulescens. Behavioural observations were combined with energetic analyses of food material to derive an estimate of the energy budgets of pre-laying and laying females. Food intake of females between arrival on the breeding grounds and incubation was considerable; estimated energy gains in this period were in the same… Expand
Is income breeding an appropriate construct for waterfowl?
TLDR
The results add to existing knowledge on the ubiquity of endogenous nutrient reserve accumulation prior to and during reproduction by waterfowl, perhaps suggesting endogenous nutrient reserves are universally used for clutch formation or incubation to some degree. Expand
Body Condition, Migration, and Timing of Reproduction in Snow Geese: A Test of the Condition‐Dependent Model of Optimal Clutch Size
TLDR
This study indicates that geese simultaneously adjust their lay date and clutch size according to their premigration condition and migratory behavior as predicted by the condition‐dependent optimization model. Expand
State-dependent incubation behaviour in the high arctic barnacle geese
TLDR
The results support the state-dependent hypothesis for incubation behaviour, suggesting that body condition at the start of incubation is an important factor for incubated behaviour in barnacle geese. Expand
Factors affecting the site of investment, and the reliance on savings for arctic breeders : the capital–income dichotomy revisited
TLDR
Birds that are able to bring sufficient endogenous reserves to the breeding ground to meet, at least partially, the demands of egg-laying can initiate clutch production soon after arrival, thereby shortening the length of the breeding season and improving the chances of reproductive success. Expand
Spring temperature, migration chronology, and nutrient allocation to eggs in three species of arctic‐nesting geese: Implications for resilience to climate warming
TLDR
Black brant (Branta bernicla nigricans) were more likely to initiate follicle development during migration, resulting in fewer days between their arrival in the Arctic and the onset of incubation and requiring a relatively greater capital investment in eggs. Expand
Nutrient Allocation Strategies to Eggs by Lesser Snow Geese (Chen caerulescens) at a Sub-Arctic Colony
TLDR
Estimates of endogenous and exogenous reserves to egg macronutrients and the source of lipids to eggs suggest advantages of larger body size for transport of body lipid reserves for long distances may be countered by the need to uselipids to fuel migration over greater distances. Expand
The Significance of Female Body Stores for Egg Laying and Incubation in Dark-Bellied Brent Geese Branta Bernicla Bernicla
TLDR
It is estimated that 52% of the energy required during incubation was derived from body stores and the rest from food intake, and it is also estimated that half of the stores were used between arrival and clutch completion, and the other half During incubation. Expand
Comparative reproductive strategies between long-tailed ducks and king eiders at Karrak Lake, Nunavut: use of energy resources during the nesting season
TLDR
Results suggest that breeding Long-tailed Ducks and King Eiders used a “mixed” breeding strategy, that is they relied on both exogenous and endogenous resources for reproduction, and knowledge about the relative importance of endogenous reserves and exogenous nutrients for egg production and incubation may help direct management decisions.

REPRODUCTIVE STRATEGIES OF NORTHERN GEESE: WHY WAIT?
Abstract Migration and reproductive strategies in waterbirds are tightly linked, with timing of arrival and onset of nesting having important consequences for reproductive success. Whether migratoryExpand
King Eider Foraging Effort During the Pre-Breeding Period in Alaska
TLDR
Female King Eiders appear to triple their foraging effort over maintenance requirements to meet the energetic challenges of egg formation, according to observations on its breeding grounds in northern Alaska. Expand

Female Feeding and Male Vigilance during Nesting in Greater Snow Geese
TLDR
The long pre-laying delay and the intense feeding activity of females suggest hat, in addition to energy reserves accumulated during the spring migration, food intake on the nesting ground may also be an important source of energy for laying Greater Snow Geese. Expand
Long-term decline in fecundity in a snow goose population: evidence for density dependence?
TLDR
The rate of the long-term decline in mean clutch size was independent of female age and breeding experience, and was not related to systematic changes in the age-structure of the breeding population. Expand
The energetics of migration and reproduction of dusky Canada geese (Branta canadensis occidentalis)
TLDR
Use of food for energy and nutrient requirements was important at all stages, accounting for 24% during incubation, the smallest but perhaps most critical contribution, to 100% during prelaying, of estimate daily energy requirements. Expand
Environmental degradation, food limitation and reproductive output: juvenile survival in lesser snow geese
TLDR
Both colony size and the density of birds using brood-rearing areas increased over the duration of the study, and mean proportion of marked goslings in a brood that survived from hatch to ringing declined from approximately 65% prior to 1980 to 35-40% in recent years. Expand
Intra-seasonal decline of clutch size in Lesser Snow Geese
TLDR
It is postulated that the seasonal decline in clutch size results mainly from a positive feed-back of female's nutrient reserves on the hormones controlling ovary development, which may be the ultimate factors responsible for the intra-seasonal clutch size decline in Lesser Snow Geese. Expand

TLDR
Because laying is a period of high nutrient requirement for females, the amount, species composition, and nutritional quality of food consumed by geese while nesting at Bylot Island, Northwest Territories is determined. Expand

TLDR
Energetics of reproduction in birds is reviewed, and observations of parent starlings confronted with manipulated brood size suggest a limit on the time that can be devoted to energetically extravagant flight activity, rather than a shortage of absolute time. Expand
