Download Nightjars books, The nightjars and their allies are amongst the most difficult of all birds to identify. Being strictly nocturnal and cryptically patterned in shades of brown, it is often necessary to rely on size, shape, habitat and voice to safely identify a species. The nightjars are by far the largest family in the order and are spread throughout the world. Some species have developed spectacular tails and wing adornments, but the majority are fairly uniform in appearance. They inhabit both forests and deserts and are ground-nesting. Many species are migratory. The forest-dwelling frogmouths of Asia and Australasia and the potoos of Latin America, adopt a less aeiral feeding strategy and nest on open branches or in tree crevices. The unique oilbird of South American nests colonially in caves, and the owlet-nighjars almost exclusively inhabit Australasia. This book fully covers this popular group of birds. The text has been thoroughly researched, both in the museum and in the field, and the plates depict feather-by-feather detail, allowing identification of all species, providing adequate views are obtained. As voice is so important in nightjar identification, an accompanying CD (priced separately) with the voices of many species will be issued simultaneously."

Download The Systematics And Evolution Of The Nightjars And Their Allies Aves Caprimulgiformes books, The modified phylogeny of the New World nightjars was utilized to investigate temporal patterns of diversification, historical biogeography and evolution of habitat choice and migratory behavior. The three New World radiations are for the most part temporally congruent but they show highly independent histories of spatial and ecological diversification that have resulted in divergent patterns of extant species distributions as well as ecology, impacted by multiple independent vicariant events, long-distance dispersal and habitat shifts.

Nightjars Rabbits And Foxes Interact On Unpaved Roads Spatial Use Of A Secondary Prey In A Shared Predator System

Download Nightjars Rabbits And Foxes Interact On Unpaved Roads Spatial Use Of A Secondary Prey In A Shared Predator System books, Abstract: Linear developments, such as roads and firebreaks, can increase encounter rates between predator and prey, which could affect predator–prey interactions and community dynamics. However, the extent to which prey responses at the interface between natural and anthropogenic habitats may be compared to those at the interface between natural habitats is unclear. Here, we used a shared‐predator system to investigate the spatial response of red‐necked nightjars ( Caprimulgus ruficollis ) to changing predation risk on roads, measured as the abundance of red foxes ( Vulpes vulpes ), and their primary prey (rabbits, Oryctolagus cuniculus ). Because all three species coexist closely on unpaved roads in Doñana National Park (Spain), we predicted that nightjars would experience increased predation risk during periods of high fox and low rabbit abundances. Birds could then modify their space use at a broad scale by moving away from risky unpaved roads or, at a finer scale, by seeking foraging microsites facilitating escape from attacks. Between 2011 and 2012, mean rabbit abundance on roads increased by 50%, and fox abundance decreased by 80%, indicating a substantial decrease in predation risk for nightjars. Unexpectedly, nightjar occurrence on roads did not increase as a consequence of the decrease in fox predation risk. However, nightjars foraging on roads became less apprehensive in their use of linear strips of roadside cover, which is known to function as a physical barrier against fox attacks. Specifically, under high predation risk, most nightjars perched on the ground nearby (15cm) tall (150cm) vegetation, whereas when predation risk decreased, they shifted to more exposed microsites near shorter (1m) stands, but rarely close to cover (45cm). Nightjars' preference for areas of high predator abundance strongly suggests that flexible microhabitat selection allows them to manage the overall predation risk independently of predator abundance. Our results highlight the importance of linear developments in determining risk exposure and prey use of apparently dangerous habitats and thus may contribute to a better understanding of risky behaviors of prey.
