Abstract

RODRIGUEZ-BARRIOS, JAVIER  and  TRONCOSO, FRANCISCO. Nesting Success of the Great-White Heron (Egretta alba) in the Department of Córdoba, Colombia. Acta biol.Colomb. [online]. 2006, vol.11, n.1, pp.123-129. ISSN 0120-548X.

Between July and November 2001, we evaluated the nesting success of the Great-white Heron (Egretta alba) during one breeding period at a shrimp pond in northeastern Colombia. We examined the relationship between nesting success and two nest variables: position within the colony (peripheral vs. central), and vertical location on sampled trees, finding a significant relationship between each pair of variables. Regression analysis showed a positive relation between nesting success and distance from the center of the mangrove. By the end of the nesting period, 52% of the nesting couples were successful, increasing the population size by 100%.
