Parental care can lead to a conflict of interest between parents and offspring. For central place foragers, conflict is expected to be particularly intensive in species that feed on relatively inaccessible, distant food resources. Some pelagic seabirds use distinct foraging strategies when provisioning young versus self-feeding: short trips near the colony versus long trips far away. Limited empirical evidence shows that the strategy used by parents depends on their own state and that of their… Expand
Foraging niche overlap during chick-rearing in the sexually dimorphic Westland petrel
TLDR
The Westland petrel Procellaria westlandica, a New Zealand endemic, is one of the rare seabirds breeding in winter, and the presence of a winter prey resource close to the colony is suggested, sufficient to satisfy the nutritional needs of breeding without increasing the foraging effort or intra-specific competition avoidance during winter.

Acoustic activity across a seabird colony reflects patterns of within‐colony flight rather than nest density
Passive acoustic monitoring is increasingly being used as a cost‐effective way to study wildlife populations, especially those that are difficult to census using conventional methods. Burrow‐nestingExpand

NIGHTLY COLONY ATTENDANCE PATTERNS OF PROVISIONING CASSIN’S AUKLET PTYCHORAMPHUS ALEUTICUS ARE CONSISTENT AND SYNCHRONOUS
MCFARLANE TRANQUILLA, L., RYDER, J.L., BLIGHT, L.K., O’HARA, P.D. & BERTRAM, D.F. 2020. Nightly colony attendance patterns of provisioning Cassin’s Auklet Ptychoramphus aleuticus are consistent andExpand
Monitoring of mercury in the mesopelagic domain of the Pacific and Atlantic oceans using body feathers of Bulwer's petrel as a bioindicator.
TLDR
It is concluded that despite a reduction in mercury levels in the Atlantic in recent decades, mesopelagic organisms in this ocean remain more heavily contaminated than in the Pacific at tropical and subtropical latitudes. Expand
Untangling causes of variation in mercury concentration between flight feathers.
TLDR
Observations confirm that the pattern of mercury concentration across primary feathers is likely an effect of the order of feather growth, whereby the earlier grown feathers are exposed to higher blood mercury concentrations than are later moulted feathers as a result of blood mercury depletion.

Dual foraging and pair coordination during chick provisioning by Manx shearwaters: empirical evidence supported by a simple model
TLDR
A simple model based on patch quality and travel time shows that for Manx shearwaters combining chick feeding and self-maintenance, bimodal foraging trip durations optimise feeding rates. Expand
Coordinated provisioning in a dual-foraging pelagic seabird
TLDR
The results show a pattern of foraging trips that indicates a high level of coordination between parents, which facilitates consistent provisioning and shows that the propensity for pairs to coordinate declines across the chick-rearing period. Expand
How can a pelagic seabird provision its chick when relying on a distant food resource? Cyclic attendance at the colony, foraging decision and body condition in sooty shearwaters
TLDR
By modelling attendance patterns with an increasing variance in the foraging routine, it is shown that the periodicity of feeding times is retained throughout the chick rearing period, indicating that cyclic attendance at the level of the whole colony is an emergent property of the two-fold foraging strategy of individual adults.

PARENTAL PROVISIONING PATTERNS OF WEDGE-TAILED SHEARWATERS AND THEIR RELATION TO CHICK BODY CONDITION
TLDR
The distribution and abundance of prey resources in the foraging environment of procellariiform seabirds may influence foraging strategies of parents, the timing and amount they feed offspring, and the duration of parental care. Expand
Flexibility in the bimodal foraging strategy of a high Arctic alcid, the little auk Alle alle
TLDR
It is found that the foraging pattern of the little auk was flexible and could be adjusted at three levels: the length of long-trips, the frequency of short-Trips, and the total time spent foraging, which resulted in reduced provisioning rates of chicks despite the fact that birds also increased the time allocated to foraging.

Simultaneous multi-colony tracking of a pelagic seabird reveals cross-colony utilization of a shared foraging area
TLDR
A large (528 foraging trips, 169 individuals), multi-year, multi-colony GPS tracking dataset mostly collected simultaneously at 4 breeding colonies across the core breeding range of a pelagic seabird, the Manx shearwater Puffinus puffinus, highlights the potential connectedness, and therefore vulnerability, of the species via a single foraging location, despite apparent segregation more locally around the breeding colonies. Expand
Foraging trip decisions by the streaked shearwater Calonectris leucomelas depend on both parental and chick state
TLDR
Although the birds did not show a clear dual foraging pattern, trip duration varied widely from 1 to 15 days, and feeding efficiency decreased as trip duration increased, parents accumulated more energy reserves when they took longer trips. Expand
Parent–offspring dietary segregation of Cory’s shearwaters breeding in contrasting environments
TLDR
It is suggested that spatial foraging constraints influence resource partitioning between pelagic seabirds and their offspring and can lead to a parent–offspring dietary segregation. Expand
Dual-foraging and co-ordinated provisioning in a tropical Procellariiform, the wedge-tailed shearwater
TLDR
It is concluded that foraging strategies in wedge-tailed shearwaters vary spatially relative to near-colony resource availability, and that dual-foraging is a general Procellariiform life-history strategy used to address similar ecological constraints in both temperate and tropical systems. Expand
Flexible foraging strategy of Cory's shearwater,Calonectris diomedea, during the chick-rearing period
TLDR
A periodic weighing protocol with Cory's shearwater chicks on Selvagem Grande island, in the northeast Atlantic, and an automatic logging system to examine the attendance of individual parents suggested that long trips can be used to restore the adult's body condition, presumably depleted during short trips.
