   "abstract": "White-eyed vireos (Vireo griseus) winter in the forests and secondary growth of the Yucatan Peninsula where\u00a0Bursera simaruba\u00a0(Burseraceae) is an abundant tree. Twenty-five per cent of all white-eyed vireos observed foraging visited\u00a0Bursera\u00a0trees. In addition, presence and abundance of territorial white-eyed vireos in small forest patches were correlated with the size of the\u00a0Bursera\u00a0crop. Vireos were the most reliable dispersers of\u00a0Bursera\u00a0seeds. These birds visited 32 of 35 trees observed for at least three hours. They accounted for approximately half of all bird visits, and two-thirds of the seeds dispersed. Most of the other species rarely visited (<5% of visits) or failed to remove seeds from the tree.Peculiarities of phenology and fruit structure may contribute to the tendency of\u00a0Bursera\u00a0to be dispersed by relatively few species. The capsules of\u00a0Bursera\u00a0fruits do not open when the fruit ripens; birds apparently locate ripe fruit using visual cues, although these are few. In addition, only a small portion of the crop ripens daily over a 7- or 8-month period. The vireo-Bursera simaruba\u00a0relationship, found regionally on the Yucatan Peninsula, may result from the prolonged fruit ripening period (October-March), the relatively depauperate frugivore community and the relatively high density of small\u00a0Bursera\u00a0trees in the hurricane-disturbed dry forests.Small trees at all times, and all trees from October to February, depend upon territorial vireos for continuous, highly efficient local dispersal of a small number of fruits. In March and April residual fruits ripen rapidly and synchronously, attracting a greater variety of visitors for broad spectrum dispersal during a period of food scarcity. Thus,\u00a0Bursera\u00a0has an unusual two-phase phenological pattern, perhaps alternately to take advantage of both specialized and opportunistic dispersers.",
