Based on our observations and those of others from the literature, we construct a graphical model of habitat use in territorial species at high densities relative to optimal habitat availability. This model ignores differences in abundance among habitats, and, together with other models of habitat use, predicts that there should be greater stability (lower turnover rates) among individuals occupying optimal habitat than among those in suboptimal habitat(s). Future studies assessing quality among habitats might take advantage of this by comparing individual turnover rates among habitat types using standard mark-recapture methodology. As an illustrative example, we present a case in wintering wood thrushes (Catharus mustelinus; Muscicapidae: Turdinae) in which relative abundance and habitat quality were inversely related. Many individuals of this nearctic-neotropic migrant species hold nonbreeding territories in the seemingly crowded rainforest of southern Veracruz, Mexico.
基于我们的观察以及文献中其他人的观察结果，我们构建了一个关于高密度领地物种相对于最佳栖息地可利用性的栖息地利用图形模型。该模型忽略了不同栖息地之间的丰度差异，并且与其他栖息地利用模型一起预测，占据最佳栖息地的个体之间应该比处于次优栖息地的个体具有更高的稳定性（更低的周转率）。未来评估栖息地质量的研究可以利用这一点，通过使用标准标记重捕方法比较不同栖息地类型之间的个体周转率。作为一个说明性例子，我们呈现了一个关于越冬画眉（Catharus mustelinus；鸫科：鸫亚科）的案例，其中相对丰度和栖息地质量呈负相关。这种新北区 - 新热带区迁徙物种的许多个体在墨西哥韦拉克鲁斯州南部看似拥挤的雨林中拥有非繁殖领地。
