Seabird researcher at Aarhus University. Endlessly fascinated by the diversity of life
Needing to model impacts on seabird populations in Northwest Europe?

Not sure where to find useful values for demographic variables?

Look no further! In this new paper, we provide model-derived values for age-specific survival of 25 species.

Demography of marine birds in the Northeast Atlantic: Informed parameter values for population modelling
We developed matrix population models for 54 regional populations of 25 marine bird species in the north-east Atlantic, based on 30 years of monitoring data. In Step 1, we parameterised the models wi...

A female Western Gull was recorded riding 150km in a garbage truck from San Francisco to a compost facility in Central CA, probably to forage. TWICE. An innovator, an icon, a genius.

Wisdom the Laysan Albatross is the oldest known wild bird and she recently laid a new egg at the Midway Atoll National Wildlife Refuge in Hawaii.

The announcement came via the United States Fish & Wildlife Service's social media on 3 December.
