Abstract Understanding the mechanisms that increase a species resilience to climate change is central predicting how they are likely respond. One determinant of vulnerability identified in multiple taxa thermal range species' distribution. In this context, with narrow ranges reportedly more vulnerable change. paradigm for environmental conditions can occupy ‘cognitive buffer hypothesis’. The cognitive hypothesis predicts larger brain sizes (relative body mass) display greater behavioural flexibility and able persist thrive within variable conditions. Following theory, we expect relative will broader be less study, collate species‐specific information 206 seabird. We then use phylogenetic generalised least squares regression path analysis quantify identify linkages connecting size, range, migration pattern, hand‐wing index, foraging behaviour, extinction risk while controlling shared ancestry between species. focused our study on seabirds, highly threatened group displays large variation these variables. Previous work has also proposed seabird narrower across their geographic distribution impacted by Consistent hypothesis, found increases size. having size or being long‐distance migrant may indirectly reduce through range. Additionally, higher index employing generalist behaviours reduces risk. Our suggests migrant, behaviour lower Identifying ecological traits promote crucial determining which most at population declines direct conservation.
