利用雾网捕获留鸟的回归分析方法，对巴拿马珍珠群岛Canas岛上的鸟类种群密度进行了估算。Canas的雾网捕获率与邻近的Puercos非常相似，后者的面积只有Canas的七分之一，但其他方面相似。这不仅证实了Puercos研究的主要结果，而且似乎还排除了Krebs等人描述的小鼠边界现象对这些鸟类的作用，在这种边界现象中，由于围栏小，受限制的种群密度大大增加。这一结果与戴蒙德对西南太平洋鸟类的观察结果一致。请参阅JSTOR的全文文章
Bird population densities on the island of Canas, Pearl Archipelago, Panama, were estimated by regression analysis of mist net captures of resident birds. The Canas mist net capture rate is very similar to those from adjacent Puercos, which is one seventh as big but otherwise similar. This not only confirms the main results of the Puercos study but also seems to rule out the action on these birds of the boundary phenomena described for mice by Krebs et al. in which confined populations greatly increased in density because of the small enclosure. The results are consistent with observations made by Diamond on southwest Pacific birds. See full-text article at JSTOR
