In contrast to the high productivity of black-legged kittiwakes in Britain, kittiwakes at many colonies in Alaska have failed chronically to reproduce since the mid 1970s. To determine if food is limiting productivity and, if so, at what stages of nesting food shortages are most severe, in 1996 and 1997 we supplementally fed kittiwakes nesting on an abandoned building. The effects of feeding were stronger in 1997 than in 1996, possibly because naturally occurring prey were of poorer quality in… Expand

Sensitivity of breeding parameters to food supply in Black-legged Kittiwakes Rissa tridactyla
TLDR
Overall, rates of hatching and fledging success, and the mean duration of incubation shifts were the most food-sensitive parameters studied and the chick-rearing stage contained more sensitive indicators of food availability than prelaying or incubation stages. Expand
Supplementary feeding increases Common Buzzard Buteo buteo productivity but only in poor-quality habitat
TLDR
This study emphasizes the importance of food availability when provisioning chicks in suboptimal habitats and has implications for the success of diversionary feeding in reducing game losses to Buzzards. Expand
Sustained increase in food supplies reduces broodmate aggression in black-legged kittiwakes
TLDR
Evidence is provided that a sustained increase in food availability affects broodmate aggression and chick survival at the nest and the various proximate and ultimate causes involved in the evolution of broodmates aggression are discussed. Expand
Effects of Food Availability on Yolk Androgen Deposition in the Black-Legged Kittiwake (Rissa tridactyla), a Seabird with Facultative Brood Reduction
TLDR
Whether food supplementation during the pre-lay period affected patterns of yolk androgen deposition in free-living kittiwakes in two years that varied in natural food availability was determined. Expand
COLONIZATION, POPULATION GROWTH, AND NESTING SUCCESS OF BLACK OYSTERCATCHERS FOLLOWING A SEISMIC UPLIFT
Abstract We present data on the colonization of Middleton Island, Alaska, by Black Oystercatchers (Haematopus bachmani) following the creation of an extensive rocky intertidal zone after the AlaskanExpand
Food abundance, kittiwake life histories, and colony dynamics in the Northeastern Pacific: implications of climate change and regime shifts
TLDR
This work simulated the dynamics of colonies with high, medium and low responsiveness of productivity to variation in nutritional stress in breeding birds, using data from Alaskan colonies, and found that the risk of quasi-extinction strongly decreased with a moderate increase in the potential number of yearly immigrants. Expand
Kittiwake diets and chick production signal a 2008 regime shift in the Northeast Pacific
TLDR
It is submitted that 2008 was an important turning point, marking a substantive reversal of warm conditions that began with the well-documented regime shift of 1977, and that interpretation is consistent with the existence of a ~60 yr cycle in ocean and atmospheric conditions in the North Pacific. Expand
Adult Brünnich's Guillemots Uria lomvia balance body condition and investment in chick growth
TLDR
The correlation between adult and chick mass represents a dynamic equilibrium in which adults simultaneously adjust their own energy reserves and their delivery rate to the chick, suggesting that this compromise must be based on behavioural choices made by individual birds and is unlikely to be a passive consequence of fluctuating conditions. Expand
Carry-over effects of food supplementation on recruitment and breeding performance of long-lived seabirds
TLDR
Light is cast on the carry-over effects of early food conditions on the vital rates of long-lived animals and support food supplementation as an effective conservation strategy for long- lived seabirds. Expand

Sensitivity of breeding parameters to food supply in Black-legged Kittiwakes Rissa tridactyla
TLDR

Behavioral ecology of black-legged kittiwakes during chick rearing in a failing colony
TLDR
Compared with their Atlantic counterparts, Black-legged Kittiwakes in North Pacific colonies are notably unproductive and contrasts between years and comparisons with data from other colonies in and outside Alaska point to food shortage as the likely cause of recurrent breeding failure on Middleton. Expand
The Annual Mortality Rate of Black-Legged Kittiwakes in NE England from 1954 to 1998 and a Recent Exceptionally High Mortality
TLDR
Circumstantial evidence suggests that the nutrients from the sewage may have been responsible for larger than normal blooms of algae, and colonies in the immediate area, particularly at Marsden, have declined dramatically. Expand
High Annual Variability in Reproductive Success of Kittiwakes (Rissa tridactyla L.) at a Colony in Western Alaska
TLDR
Numbers of adult-plumaged birds on the cliffs in mid-season were markedly lower and more variable in years when few nests were built, suggesting that relatively few experienced adults breed and consistently are present at the colony in yearsWhen overall reproductive performance is poor. Expand
An experimental study of reduced parental effort and future reproductive success in the puffin, Fratercula arctica
TLDR
The study demonstrated inter-year reproductive costs for puffins and supported the hypothesis that long-lived species reduce the ‘quality’ of their offspring or abandon a breeding attempt rather than compromise their survival and future opportunities to reproduce. Expand
Experimental evidence for food limitation of egg production in gulls
TLDR
The results clearly indicate that egg production can be limited by poor food supply during the laying period, but suggest that such food limitation is not a proximate mechanism for the restriction of the normal clutch to three. Expand
PREY SWITCHING AND VARIABLE FORAGING STRATEGIES OF BLACK-LEGGED KITTIWAKES AND THE EFFECT ON REPRODUCTIVE SUCCESS
TLDR
Time spent traveling and trip distance increased with greater trip duration, however, search and prey capture times were only weakly related to trip duration and may reflect foraging strategies that vary with different species, age classes, or availability of prey consumed. Expand
THE IMPACT OF ADDITIONAL FOOD PROVISIONING ON CHICK GROWTH AND BREEDING OUTPUT IN THE HERRING GULL LARUS-ARGENTATUS - A PILOT EXPERIMENT
TLDR
It seems likely that the negative impact of food shortage on chick survival under present conditions is mainly mediated through an effect of parental guarding behaviour. Expand
Antipredator benefits of nest-site selection in Black-legged Kittiwakes
TLDR
This study implicates large- and fine-scale aspects of nest-site selection by Black-legged Kittiwakes, with large-scale cliff structure being the most important. Expand
