In addition to their unique body adaptations, birds have a range of described behaviours that differ from the foraging behaviours of other animal groups. According to the foraging habitat, birds may be grouped into foraging guilds. Foraging includes a range of activities, starting with the search for food, making use of sensory abilities, and ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
The fishing industry sometimes catch forage fish for commercial purposes (i.e. as seafood), but primarily for use as feeder fish to raise more valuable piscivorous animals (e.g. salmon farms). Some fisheries scientists are expressing concern that this will affect the populations of predator fish that depend on them. [4]
A forager is a person who collects edible plants or fungi for consumption. Urban foragers may collect in city parks, private lands, and sidewalks. Urban foraging has gained in popularity in the 21st century, as people share their knowledge, experiments, and research about local flora online.
