DESCRIPTION: Intra-specific competition is especially challenging for colon
 ial species because the number of individuals is higher near the colony\, 
 and resources are depleted faster. Coexistence with conspecifics hence dep
 ends on mechanisms that minimize competitive interactions and favor resour
 ce partitioning. In the first chapter of my thesis\, I analyze how individ
 ual differences in movement behavior facilitate coexistence\, and the cost
  associated to different movement strategies. I used location and accelero
 meter data from 21 oilbirds\, a cave-dwelling colonial tropical frugivore\
 , from Cueva del Guacharo in Venezuela. I characterized movement patterns 
 and the length of the periods they roost outside of the cave\, and classif
 ied individuals into one of three movement strategies. Oilbirds reduced in
 ter-individual competition by combining spatial segregation with site fide
 lity. I found that the species performs partial nomadic migrations\, with 
 individual variation in time\, duration and destination. Migratory individ
 uals expended less energy than individuals that perform any other strategy
  by reducing the number of commute flights between the cave and the foragi
 ng areas. These differences could have fitness consequences and highlight 
 the importance of mechanisms that enable stable coexistence in colonial sp
 ecies. I will also present ideas and progress on further chapters that inc
 lude collaborations in Colombia\, where we have tagged 51 oilbirds\, and w
 ill study the effects of habitat fragmentation on the cost of movement. Fe
 edback and ideas will be appreciated.\nSpeaker: Gustavo Alarcon-Nieto
