Changes in over-winter prey availability, rather than winter climate, are associated with a long-term decline in a northern Tawny Owl population
Although the associations between climate, food conditions and reproduction in the wild has been the focus of numerous studies in recent years, we still know little about population level responses to climate and fluctuating food conditions in long-lived species and during longer periods of time. Here, we assessed the relative importance of the abundance of the main prey in winter (small mammals),
