TL;DR: For example, a single bird may have many names, and a single species of a bird may even have multiple names as mentioned in this paper, and the names of birds can be assigned to different groups or species of birds.

TL;DR: For example, large soaring birds often roost on cliffs and large structures, and thus are restricted to areas where safe take-offs and landings can be safely taken off and landing as discussed by the authors.
Abstract: Roost site preferences influence the spatial distribution of species. Large soaring birds often roost on cliffs and large structures, and thus are restricted to areas where safe take-offs and landi...

TL;DR: The macronutrient preferences of Common Mynas in captivity suggest the Common Myna will continue to be distributed mainly in urban areas of South Africa where anthropogenic foods relatively high in fat are more common.
Abstract: Common Mynas Sturnus tristis, previously known as Acridotheres tristis, are considered among the world’s worst most invasive species. However, relatively little is known about the factors that affe...
