Sexing a Monomorphic Plumage Seabird Using Morphometrics and Assortative Mating
TLDR
External body measurements are useful to sex Long-tailed Jaegers, a slightly dimorphic species, and measurements of both members of a pair considerably improve the accuracy of sexing, likely due to the presence of assortative mating.
A rare dark morph in the Canadian Arctic raises questions about molting and polymorphism in Long-tailed Jaeger (Stercorarius longicaudus)
TLDR
Observations conducted in the Canadian Arctic are described and it is shown that Long-tailed Jaegers can apparently exhibit dark morph adult-like plumage (i.e., individuals showing some obvious criteria associated with definitive alternate ‘adult breeding' plumage).
An overview of migratory birds in Brazil
TLDR
Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory, and 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratories, while a few species wereclassified as Vagrant and eight could not be defined due to limited information available, or due to conflicting data.
An update on the inventory, distribution and residency status of bird species in Guatemala
Summary. We present an update on the status and distribution of birds in Guatemala relative to a previous summary (Eisermann & Avendaño 2007) and based upon a review of new published and unpublished
Flexibility in otherwise consistent non-breeding movements of a long-distance migratory seabird, the long-tailed skua
Quantifying within- and between-individual variation in animal migration strategies is a first step towards our understanding of the ability of migrants to adjust to changes in the environment. We
First Observation of a Four-egg Clutch of Long-tailed Jaeger (Stercorarius longicaudus)
TLDR
The first documentation of a clutch of four eggs in a Long-tailed Jaeger nest found at Zackenberg in northeastern Greenland is presented.
Survival Rate of the Long-Tailed Jaeger at Alert, Ellesmere Island, Nunavut
TLDR
Estimating the apparent survival rate of adult Long-tailed Jaegers breeding at one of the most northerly sites on earth, northern Ellesmere Island, Canada suggests that conditions at sea during the nonbreeding season may be more important in affecting annual survival.
Trans-Equatorial Migration Routes, Staging Sites and Wintering Areas of a High-Arctic Avian Predator: The Long-tailed Skua (Stercorarius longicaudus)
TLDR
This study has revealed important marine areas in both the south and north Atlantic Ocean that sustainable management of these ocean basins will benefit Long-tailed Skuas as well as other trans-equatorial migrants from the Arctic.
Post-breeding migration of four Long-tailed Skuas (Stercorarius longicaudus) from North and East Greenland to West Africa
The Long-tailed Skua (Stercorarius longicaudus) is a specialist predator of lemmings during the summer and hence an important component of the tundra ecosystems, but most of its life cycle takes
