| The Tropical Monitoring Avian Productivity and Survivorship (TMAPS) program was established in 2008 to provide inferences about life history and demographic parameters of landbirds on Saipan, Northern Mariana Islands, through pulses of mark-recapture effort during each annual wet and dry season. Prior to the wet season of 2015, Typhoon Soudelor passed over Saipan as a Category 5 super-typhoon. Landbird populations declined between the dry and wet seasons of 2015, likely because of direct and indirect impacts of Soudelor. Adult survival of Rufous Fantail and Bridled White-eye declined after the storm, while Golden White-eye populations appeared to change little. For Rufous Fantail, effects of Soudelor on survival varied by location. Survival was greater at locations with relatively more native vegetation, and lower in more invaded locations. Temporary emigration also peaked for Rufous Fantail and Golden White-eye in the period corresponding to Typhoon Soudelor. All three species rebounded to levels observed prior to Soudelor by the 2016 dry season. These results represent a rare contribution to our understanding of how bird populations respond to severe disturbances by elucidating vital rates and changes in abundance while controlling for variation in capture and recapture probabilities associated with the storm. |
