Flying Birds Wallpapers Biography
Guilds are groups of species in a community that exploit the same set of resources in a similar manner, but are not necessarily closely related taxonomically. Birds that hunt for insects on the floor of a deciduous forest constitute a guild; tropical American hummingbirds and butterflies jointly form a guild of daytime nectar feeders; desert sparrows, ants, and rodents constitute a seed-eating guild. Members of guilds often differ in their precise food requirements, thus reducing the potential for competition among them when resources are limited. In a given locality, the membership of a guild can change through the year as migrants are added or subtracted.
For example, in the oak woodland on Stanford University's jasper Ridge Biological Preserve, Chestnut-backed Chickadees, Hutton's Vireos, and Plain Titmice are resident species that form the core of a foliage- and bark-gleaning guild of insectivores. These are joined as core species by Ruby-crowned Kinglets and Yellow-rumped Warblers fall and winter, and by Blue-gray Gnatcatchers in the spring. Other guild members include Downy Woodpeckers, Bushtits, White-breasted Nuthatches, Brown Creepers, Wrentits, Bewick's Wrens, Warbling Vireos, and Townsend's Warblers
