在缅因州的针叶林和哥斯达黎加的越冬地，研究了5种林莺(Dendroica tigrina、D.coronata、D.virens、D.fusca、D.Castanea)的种群调节。虎纹夜蛾和卡氏夜蛾在一定程度上依赖于食物过剩的时期，而其余物种的种群数量与它们偏爱的摄食区的叶量大致成正比。觅食位置、行为和筑巢日期的不同，加上栖息地偏好的微小差异，以及可能领土对同一物种比对其他物种有更强的调节作用的趋势，允许物种共存。
Population regulation of 5 species of warbler (Dendroica tigrina, D. coronata, D. virens, D. fusca, D. castanea) was studied in coniferous forests in Maine and on wintering grounds in Costa Rica. D. tigrina and D. castanea are partly dependent upon periods of superabundant food, while remaining species maintain populations which are roughly proportional to volume of foliage in their preferred feeding zones. Differences in feeding position, behavior, and nesting date, combined with slight differences in habitat preference and perhaps a tendency for territoriality to have a stronger regulating effect upon the same species than on others, permit coexistence of species.
