Strolling through a century: replicating historical bird surveys to explore 100 years of change in an urban bird community

Mason Fidino, Kelvin Limbrick, John Bender, Travis Gallo & Seth Magle
In 1898, Herbert and Alice Walter started a 5-year survey of birds in Lincoln Park, – the largest park in Chicago, IL – and summarized their data in an urban birding field guide, ‘Wild Birds in City Parks’. Twenty-nine years later, William Dreuth compared the relative frequency of species between the Walter’s study to their own 5-year Lincoln Park survey. Between 2012 and 2015, we replicated these surveys to investigate a century of bird diversity...

A multi-state occupancy model to non-invasively monitor visible signs of wildlife health with camera traps that accounts for image quality

Maureen Murray, Mason Fidino, Elizabeth Lehrer, Juniper Simonis & Seth Magle
Camera traps are an increasingly popular tool to monitor wildlife distributions. However, traditional analytical approaches to camera trap data are difficult to apply to visible wildlife characteristics in single images, such as infection status. Several parasites produce visible signs of infection that could be sampled via camera traps. Sarcoptic mange (Sarcoptes scabiei) is an ideal disease to study using cameras because it results in visible hair loss and affects a broad host range. Here, we...
