Document Summary
Netherlands, and france: ifdt would suggest that movement coincides with food intake/reproductive success. Iii: distribution was not uniform-birds achieved equal food intake by shifting from site to site depending on food availability. Territorial defense: territorial males attempt to monopolize high-quality sites, free (cid:373)o(cid:448)e(cid:373)e(cid:374)t is (cid:862)dis(cid:272)ouraged(cid:863) (cid:271)(cid:455) territorial (cid:373)ales-forced to look elsewhere for breeding sites, holding quality territories attracts females and increases chances of reproduction. Territorial defense benefits: increases chances of reproductive opportunities, depleting competitive neighbors allows larger territory and increased access to food and water resources, in order to be adaptive: fitness benefits of pushing out neighbors must outweigh the costs. Vi: incoming fall= incoming breeding season and territoriality is heightened, common to many males of many species. Cost-benefit approach: if territoriality is costly than those with the best territory holding ability (usually fighting ability) should hold the highest quality habitats.
