The birds and the Bayes – new statistical approaches to modelling seabird flight heights

In this post Viola Ross-Smith discusses her recent paper ‘Modelling flight heights of lesser black-backed gulls and great skuas from GPS: A Bayesian approach‘. Although the need for renewable energy and its benefits are now widely recognised, this technology does not come without implications for biodiversity and the environment. For this reason, it’s important to assess and quantify the potential risks of renewables to wildlife … Continue reading The birds and the Bayes – new statistical approaches to modelling seabird flight heights

Can’t see the puffins for the auks? Estimating population size with imperfect species identification

In this post, Alison Johnston (@ali__johnston) talks about her paper published today “Modelling the abundance and distribution of marine birds accounting for uncertain species identification”. Ecological surveys balance the competing goals of data quality and data quantity. We can intensively survey a small area, or cover a larger area with less detail and precision, for example in large-scale citizen science surveys. Recently there has been … Continue reading Can’t see the puffins for the auks? Estimating population size with imperfect species identification
