Guayacán Guaiacum sanctum Fruiting, Río Motagua Valley, Arid Interior, Deciduous Dry Scrub Forest, Departamento de Zacapa, Guatemala. 1984 Photo by Peter W. Wendelken

In Zacapa, Guaiacum sanctum fruit is consumed by and/or transported by adult birds to nestlings and fledglings in at least 19 species of birds: Orange-fronted Parakeet, White-fronted Parrot, Russet-crowned Motmot, Turquoise-browed Motmot, Golden-fronted Woodpecker, Great Kiskadee, Social Flycatcher, Tropical Kingbird, Rose-throated Becard, White-throated Magpie Jay, Clay-colored Robin, Tropical Mockingbird, Blue-gray Tanager, Yellow-winged Tanager, Grayish Saltator, Rose-breasted Grosbeak, Great-tailed Grackle, Streak-backed Oriole, and Altamira Oriole.

These data are based on the field study done by Peter Wendelken in Guatemala in 1984 when he lived in Teculután, Departamento de Zacapa. A PDF version of the paper resulting from the study may be accessed via the following link.
