THE ORIGIN AND DIVERSIFICATION OF GALAPAGOS MOCKINGBIRDS
TLDR
A molecular phylogeny of Galapagos and other mockingbird populations based on mitochondrial sequence data indicated that Nesomimus is nested within the traditional genus Mimus, making the latter paraphyletic, and that the closest living relatives appear to be those currently found in North America, northern South America, and the Caribbean.
Coloniality in the Cliff Swallow: The Effect of Group Size on Social Behavior
TLDR
This study of vertebrate coloniality should be of interest to all who study social animals, including behavioural ecologists, population biologists, ornithologists and parasitologists, and should also appeal to evolutionary biologists and to psychologists studying decision making in animals.
Foraging destinations of three low‐latitude albatross (Phoebastria) species
TLDR
Foraging distributions of three congeneric species of albatrosses that nest in the tropics/subtropics were identified and analysis of movement patterns showed that the core feeding areas during long trips were located over the continental shelves of North and South America.
Oceanographic habitats of two sympatric North Pacific albatrosses during the breeding season
We characterized the movements and oceanographic habitats of black-footed (Phoebas- tria nigripes) and Laysan (P. immutabilis) albatrosses during the brooding and the rearing periods of the breeding
Sexual size dimorphism and food requirements of nestling birds
TLDR
A review of all related studies shows a strong positive association between the degree of sexual size dimorphism and gender difference in food requirements.
Evolution of Obligate Siblicide in Boobies. 1. A Test of the Insurance-Egg Hypothesis
TLDR
A field study of the obligately siblicidal masked booby demonstrated that second eggs contribute a surviving hatchling after the first egg's failure in 19.2% of two-egg clutches.
Brood Size and Food Provisioning in Masked and Blue‐Footed Boobies (Sula Spp.)
TLDR
Compared with typical pelagic seabirds, Masked and Blue-footed Boobies have similar capacities to provision two-chick broods; some other factor limits MaskedBoobies, but not Blue-footers, to fledging single chicks.
Comparison of light- and SST-based geolocation with satellite telemetry in free-ranging albatrosses
TLDR
Combining measures of light-based longitude and SST-based latitude significantly reduces the error in location estimates for albatrosses and can provide valid latitude estimates during the equinoxes, when light- based latitude measurements are indeterminate.
Wind, Waves, and Wing Loading: Morphological Specialization May Limit Range Expansion of Endangered Albatrosses
TLDR
These results are the first to integrate global wind and wave patterns with albatross aerodynamics, thereby identifying morphological specialization that may explain limited breeding ranges of two endangeredAlbatross species and are further relevant to understanding past and potentially predicting future distributional limits of albatosses globally, particularly with respect to climate change effects on basin-scale and regional wind fields.
Sexually dimorphic eggs, nestling growth and sibling competition in American Kestrels Falco sparverius
TLDR
The influence of sibling egg size ratios on post-natal size relationships persisted through the nesting period, providing parents with a tool to manipulate size-related phenomena in their offspring.
