Summary: | Previous Mourning Dove (Zenaida macroura) nesting studies conducted in areas containing a mixture of edge and continuous habitats have focused on edge habitats. Consequently, little is known about the potential contribution of continuous habitats to dove production. In this study we evaluated the relative importance of these two extensive habitat types by monitoring the habitat use and nest success of 59 radio-marked doves during 1990-1991 in central Missouri. Of 83 nests initiated by our marked sample, most (81.9%) were located in edge habitats. Although continuous habitats were selected less as nest sites, the proportion of successful nests did not differ significantly from that in edge habitats. Our data indicate that continuous habitats should not be considered marginal nesting habitat. It the intensity of use and nest success that we observed are representative regionally or nationally, continuous habitats could contribute substantially to annual Mourning Dove production because of the high availability of these habitats throughout much of the Mourning Dove breeding range. /// Los trabajos previos sobre el anidamiento de la tórtola Zenaida macroura en area que contienen una mezcla de borde y habitat continuo han enfocado en los habitats de borde. Consecuentemente, se conoce poco sobre la contribución potencial de habitat continuo en la producción de la tórtola. En este trabajo evaluamos la importancia relativa de estos dos tipos de habitats, monitoreando mediante el uso de radiotransmisores, el uso de habitat y exito de anidamiento de 59 aves. El estudio se llevó a cabo en la parte central de Missouri de 1990-1991. De 83 nidos comenzados por las aves monitoreadas, la mayoria de estos (81.9%) se localizaron en habitats de borde. Aunque los habitats continuos fueron menos seleccionados por las tórtolas, no se encontro diferencia significativa en la proporcion de nidos exitosos entre los dos tipos de habitats. Los datos obtenidos indican que el habitat continuo no debe ser considerado habitat marginal para la especie. Si la intensidad de uso y exito de anidamiento observado en este trabajo son representativos de la situacion regional o nacional, el habitat continuo puede contribuir sustancialmente a la producción anual de esta tórtola, dado la gran disponibilidad del mismo a través de toda la zona utilizada para reproducirse por esta ave. |
