![]() Temporal variation in greenness affected the productivity of each bird species in unique ways. Rainfall was positively related to vegetation greenness at all but the highest rainfall levels. Here we leveraged avian capture-recapture, rainfall, and remote-sensed habitat data (enhanced vegetation index ) to assess relationships between rainfall, vegetation greenness, and demographic rates (productivity, adult apparent survival) of three native bird species on Saipan, Northern Mariana Islands: rufous fantail ( Rhipidura rufifrons), bridled white-eye ( Zosterops conspicillatus), and golden white-eye ( Cleptornis marchei). Yet, little is known about environmental influences on population dynamics for most islands and species. Spatial and temporal patterns in rainfall and plant productivity may be important in driving dynamics of these species. ![]() Remote tropical oceanic islands are of high conservation priority, and they are exemplified by range-restricted species with small global populations. ![]()
