几种新北-新热带区迁徙鸣禽似乎形成栖息集群，而在其越冬的理由，但很少有人了解这种行为的生态。在波多黎各的三个冬季（2002 ~ 2004年），我们利用无线电遥测技术研究了北方水鸫Seiurus noveboracensis的栖息行为和栖息地选择模式。总体而言，红红树林被选为栖息不成比例的可用性。无论昼夜栖息地使用，87%（n = 86）的北方水鸟选择密集的海岸红红树林栖息地。个人前往2公里，每天访问栖息地在这个栖息地。大多数（8 14）的个人单独栖息，而其他栖息在松散的聚集附近的灰色王鸟Tyrannus dominicensis的公共栖息地。栖息地的选择模式并没有因性别而异。个人表现出积极的反应，在白天播放，然而，选择栖息地显着接近海岸。另有几种候鸟和留鸟也利用红红树林作为夜间栖息地。红红树林可能是生活在新热带沿海地区附近的鸟类种群的重要夜间栖息地。夜间栖息行为的好处，以及为什么个人似乎选择红色红树林仍然知之甚少。
Several species of Nearctic-Neotropical migratory songbirds appear to form roosting aggregations while on their wintering grounds but little is understood about the ecology of this behavior. We studied roosting behavior and patterns of roost habitat selection in the northern waterthrush Seiurus noveboracensis, during three winter years (2002� 2004) in Puerto Rico using radio telemetry. Overall, red mangrove was selected for roosting disproportionately to its availability. Regardless of diurnal habitat used, 87% (n � 86) of northern waterthrush selected dense stands of coastal red mangrove for roost sites. Individuals traveled up to 2 km to access roost sites in this habitat on a daily basis. The majority (8 of 14) of individuals roosted alone, while others roosted in loose aggregations near communal roosts of gray kingbirds Tyrannus dominicensis. Patterns of roost site selection did not vary by sex. Individuals showing aggressive response to playback during the day, however, selected roost sites significantly closer to the coast. Several additional migratory and resident bird species also used red mangrove for night-time roosting habitat. Red mangrove may be a critical nocturnal roosting habitat for bird populations that live in proximity to coastal areas in the Neotropics. The benefits of nocturnal roosting behavior as well as why individuals appear to select red mangrove remain poorly understood.
