Nightjars: from mystery to model in Ecology and Evolution

The Neotropical realm, ranging from central Mexico south to Argentina, is home to 50 nightjar and nighthawk species in 15 genera, representing about half of all Caprimulgidae. The highest diversity is in South America, where 36 species (26 endemic) occupy virtually all environments from sea level to treeline, including grasslands, deserts, forests and rivers. Multiple lines of evidence indicate that this already extraordinary diversity is still underestimated, with some taxa likely involving more than one species. Similarly, Neotropical nightjars present an under-appreciated diversity of ecological and behavioural strategies with important potential for contributing to our broader understanding of avian life histories, breeding and migration systems. Recent Neotropical studies reveal a much more diverse picture of caprimulgid ecology that challenges current generalizations. Promising new research tools include automatic acoustic recorders for bioacoustics, DNA sequencing and vocal analyses for studies of taxonomy, data loggers and camera traps for reproductive biology and social behavior, and GPS tags and geolocators for migration studies. Whereas the scenario for research is favorable, several Neotropical nightjars may be experiencing undetected population declines, influenced by habitat loss, introduced predators, declining aerial insects, and climate change.TUVE QUE INVENTAR EL ISBN PORQUE EL LIBRO NO ESTA PUBLICADO Y NO SE EL ISBN
