Morphometric estimates of body condition are widely used by ornithologists, but which
estimates work best is a matter of debate. We review morphometric approaches (body mass …

Environmental factors influence breast cancer incidence and progression. High body mass
index (BMI) is associated with increased risk of post-menopausal breast cancer and with …

Conditions experienced during development can have long-term consequences for
individual success. In migratory songbirds, the proximate mechanisms linking early life …

Costs of reproduction represent a common life‐history trade‐off. Critical to understanding
these costs in migratory species is the ability to track individuals across successive stages of …

Body composition of birds is often used to assess in part the “condition” of individuals in the
context of their life history and ecology. We describe contemporary non-destructive (non …

Radio telemetry can be a valuable tool for studying the behavior, physiology, and
demography of birds. We tested the assumption that radio transmitters have no adverse …

We compared the use of body stores in breeding Barnacle Geese (Branta leucopsis) in
traditional Arctic colonies in the Barents Sea with that in recently established temperate …

Quantifying a relationship between heart rate (f H) and rate of oxygen consumption (V̇ O2)
allows the estimation of V̇ O2from f H recordings in free-ranging birds. It has been …

Over the past decades most goose populations have become increasingly dependent on
agricultural crops during wintering and migration periods. The suitability of agricultural crops …

We conducted the first validation of the deuterium dilution method as a nonlethal technique
for estimating the body composition of a shorebird during fall staging as birds fatten in …
