Niche Relationships Among Six Species of Shorebirds on Their Wintering and Breeding Ranges

摘要: The dynamics of the organization a community six species migrant predatory shorebirds (Least Sandpiper, Semipalmated Dunlin, Short—billed Dowitcher, Lesser Yellowlegs, and Plover) was appraised by studying foraging behavior habitat utilization under winter conditions in southern Florida summer eastern Canadian Arctic. Eight methods, defined primarily on basis how bill is used pattern locomotion, constitute behavioral repertoire species. Each method correlated with particular rate locomotion (distance/time) feeding (pecking or probing/time). Feeding rates seem independent air temperature, number conspecifics, total nearby. Instead, seasonal changes these are probably related to food density. On findings differences between most reason...
