Abstract
Three coffee farms were studied to determine avian feeding guild diversity differences between sun-grown and shade-grown plots in San Luis Valley, Monteverde, Costa Rica. Sun-grown and shade-grown plots were observed on three coffee farms, species were identified by sight, and separated into feeding guilds. Using the Shannon-Weiner Diversity Index, we found a significantly greater overall avian diversity in sun-grown plots (Modified t-test, t= -4.00, df = 267.36). We also found no significant difference in feeding guild diversity between sun-grown and shade-grown plots, but found a significant difference within insectivorous and omnivorous feeding guilds supporting greater diversity in the sun-grown plots (Modified t-Test, Insectivorous: p > 0.05 t = -2.28, df = 102.51, Omnivorous: p > 0.05, t = -2.84, df = 98.67). This comparison could indicate the sun-grown plots in San Luis Valley, Costa Rica to be a more productive system, whereas shade-grown plots are dominated by two species affecting overall diversity.
Resumen
Se estudio tres fincas de café para determinar la diferencia de la diversidad gremial de alimentación aviar entre las parcelas cultivadas al sol y en la sombra en el valle de San Luis, Monteverde, Costa Rica.
