  • Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models to understand foraging; many of these models are a type of optimality model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include resources, the elements necessary for survival and reproduction which have a limited supply, predator, any organism that consumes others, and prey, an organism that is eaten in part or whole by another. Behavioral ecologists first tackled this topic in the 1960s and 1970s. Their goal was to quantify and formalize a set of models to test their null hypothesis that animals forage randomly. Important contributions to foraging theory have been made by: * Eric Charnov, who developed the marginal value theorem to predict the behavior of foragers using patches; * Sir Kevin Durant, with work on the optimal diet model in relation to tits and chickadees; * John Goss-Custard, who first tested the optimal diet model against behavior in the field, using redshank, and then proceeded to an extensive study of foraging in the common pied oystercatcher (en)
  • Le terme fourrageage, mot dérivé du verbe fourrager, désigne la recherche de nourriture dans la nature par les animaux et les êtres humains — dans ce dernier cas, il s'agit d'approvisionner le bétail ou de se nourrir. L'on peut aussi utiliser le terme de « fourragement ». Le nourrissage désigne pour les animaux l'action de se nourrir ou le fait d'être nourri. Historiquement, le terme est aussi utilisé dans le jargon militaire, notamment dans l'intendance de la cavalerie, pour désigner l'action d'approvisionner les chevaux (recherche de fourrage - foin, paille,…), la troupe.

  • Foerageren is de biologische term voor het regelmatig terugkerend zoeken en vinden van voedsel door dieren. Wanneer vogels of andere dieren regelmatig een bepaald gebied gebruiken om zich te voeden, dan spreekt men van een foerageergebied. Als de vogels in het foerageergebied ook verblijven en broeden wordt het ook rustgebied genoemd. Meerdere foerageer- en rustgebieden zijn een gedeelte van het jaar niet voor het publiek toegankelijk, om vooral trekvogels de nodige rust te gunnen bij het foerageren. Voorbeelden in Nederland en België zijn de Buitenwaarden in de uiterwaarden van de IJssel bij Wijhe, het Panneweel in het Saleghem Krekengebied en het Nationaal Park Duinen van Texel. (nl)
  • Forrageamento é a busca e a exploração de recursos alimentares. É uma habilidade particularmente importante pois afeta a aptidão do animal, influenciando diretamente a sobrevivência e a reprodução do organismo. O forrageamento é estudado pela ecologia comportamental, analisando o comportamento de forrageio dos animais em resposta ao ambiente em que ele vive. Ecólogos utilizam modelos matemáticos para entender o forrageamento; muito desses modelos utilizam o que seria ótimo em termos de busca e valor nutricional. Nesses modelos, a decisão de escolher determinado item é feita em base no ganho entre o que animal obtém de energia e o que gasta ao buscar tal item alimentar. A "teoria do forrageamento ótimo" prediz que os animais forrageam buscando o maior aporte de energia por alimento com o menor custo na busca. Palavras chave para descrever o forrageamento são: 1) Recursos, que são os elementos necessários para reprodução e sobrevivência dos indivíduos e são limitados no meio ambiente; 2) Predador, que é qualquer organismo que consome outro; 3) Presa, que é o organismo que é consumido.
