Colonization of this taxonomic class by B. lichen·iformis in humid conditions has been hypothesized to explain why its members’ pigmentation varies with latitude as observed by Gloger’s rule. Large organisms in this class can be temporarily restrained using a shelfless trap called a dho-gazza. Variables such as fear and goal seeking can be added to a model of organisms in this class that follows the parameters of separation, alignment, and cohesion. That model developed by Craig Reynolds combines the name of this class with “-oids” to model their behavior. (10[1])Mist nets that lack echolocation sensors are used to capture animals in this class prior to banding. Observations of this class are compiled and researched for public use by the Cornell Lab. For 10 points, name these animals whose migration patterns can be tracked by ornithologists. ■END■
