Multiple stressors: negative effects of nest predation on the viability of a threatened gull in different environmental conditions
The majority of the world's seabirds show substantial population declines, but a detailed understanding of the phenomenon is lacking. A potentially important mechanism that has received momentum lately is nest predation. This study aimed to assess the populationviability of a threatened population of the lesser black-backed gull Larus fuscus fuscus under different scenarios for nest predation and environmental conditions. We merged results from statistical analyses of 16 years of empirical data with a Leslie model, emphasising the impact of predation at the nesting stage. In the model, we quantified the effect of multiple stressors on the viability of the lesser black-backed gull according to the IUCN Red List's 'Vulnerable' criteria (30% reductions in population size over < 3 generations). First, the empirical analyses showed that the estimated apparent survival probability, which showed declining temporal trends, was on average 0.862 and 0.470 for adults and juveniles, respectively. The average clutch size in the absence and presence of nest predation was 2.836 and 0.935 eggs nest−1, whereas the average number of fledglings nest−1 was 0.452, respectively. Nest predation and chick production showed a concave-up temporal trend, whereas clutch size showed no trend. Second, based on the predictive models, we documented multiple stressor effects: nest predation was the single-most-important stressor, but its adverse effect was severely amplified when environmental conditions were poor. When important nest predators were present, L. f. fuscus met the 'Vulnerable' criteria. Nonetheless, when nest predation was absent or low, the status of our population was following IUCN Red List's 'Least Concern' criteria (its official status). Nest predation played a vital role in limiting population growth – a finding that is likely to be relevant for several other seabirds in northern Europe

How to know a crow : the biography of a brainy bird
Crows are all around us, shouting from lamp posts, poking around on lawns, and generally taking a bright-eyed interest in everything that moves. But most of us don't know much about their lives. Author Candace Savage invites us into the fascinating world of these big, brash, and surprisingly brainy birds. From the moment baby crow Oki pokes her egg tooth through her shell and emerges into her nest, we are her constant companions. As we follow her through the seasons of her life, we explore how crows see and sense the world, and uncover the answers to questions such as: Do crows have families? How do crows communicate with one another? Do crows play? How can we interact with them?

Crow smarts : inside the brain of the world's brightest bird
\"One of the biggest differences between humans and animals is the ability to understand the idea of 'If I do X, Y might happen.' New Caledonian crows seem to possess the intelligence to understand this causal concept. Why do crows have this ability? What does the crow know and what does it tell us about brain size, the evolution of intelligence, and just who is the smartest creature on the planet? In the latest addition to [this] series, the creators of The Frog Scientist take us to a beautiful Pacific island, where a lively cast of both crows and scientists is waiting\"--Amazon.com.
