Predation Rates

Ground-nesting birds typically experience high predation rates on their nests, often by mammalian predators. As such, researchers and wildlife managers have employed numerous techniques to mitigate nest predation. We investigated the use of scents as repellents to deter predators from both artificial and natural ground nests. Survival rates of artificial nests did not differ among six groups of substances (Wald ?2 df = 5 = 4.53, P < 0.48); however the chronology of predation among groups differed. A commercial Coyote urine based deterrent (DEER-D-TERTM), human hair, and Worcestershire sauce were depredated faster than the control (F4,5 = 40.3, P < 0.001). Nest survival of natural nests differed among those groups tested (Wald ?2 df = 2 = 11.8, P < 0.005); the eight mothball treatment decreased survival (Wald ?2 df = 1 = 11.5, P < 0.005), which indicated that novel smells may attract predators or result in duck nest abandonment when coupled with natural duck scent. Chronologies of predation events among treatment groups were not different for natural nests (F2,3 = 1.9, P = 0.22). These findings indicate an interaction between novel scents and predator olfactory cues.

Abstract Artificial nests are commonly used to investigate relative rates of nest predation in birds, but several methodological considerations need to be addressed before results from natural and artificial nests can be compared. Using field and laboratory experiments, we examined responses of predators to visual and olfactory cues that were associated with wicker nests and their contents. Avian predators did not discriminate between wicker nests dipped in mud and those covered by a camouflage fabric, whereas mammalian predators showed a weak tendency to depredate camouflaged nests. Nests containing plasticine eggs were depredated more often than nests containing only quail eggs and finch eggs, although no response to number of plasticine eggs in nests was found. The higher predation of nests with plasticine eggs may have resulted because small mammals, relying on olfactory cues, comprised a large portion of the predator assemblage. Field results were supported in tests where captive deer mice (Peromyscus maniculatus) were attracted to assortments of egg types that included plasticine. Time required by captive deer mice to penetrate quail eggs and finch eggs versus plasticine eggs varied as a function of egg size and shell thickness and strength. Overall, domestic finch eggs provided a better alternative to quail eggs because they were small enough to allow detection of predation events by small mammals and did not have an unnatural odor like plasticine. Potential problems with nest concealment, egg visibility, egg odors, and other factors must be resolved to enhance the design and reliability of artificial nest experiments.

AbstractWe monitored 142 Black-capped Vireo (Vireo atricapillus) nests at Fort Hood, Texas, from 1998 to 2001 using time-lapse infrared videocameras to identify nest predators. We recorded 59 predator visits (where at least some of the nest contents were removed or destroyed), resulting in 48 depredated nests. Snakes and fire ants (Solenopsis spp.) were the leading predators, accounting for 18 (38%) and 15 (31%), respectively, of all depredated nests. We also identified a variety of avian (19% of depredated nests) and mammalian predators (11% of depredated nests). Despite intensive Brown-headed Cowbird (Molothrus ater) removal at Fort Hood, we recorded nine predator visits by females of this species, but only one resulted in nest failure. Although predator visits occurred at all hours, most (58%) took place at night. The daily predation rate was higher during the nestling stage than during incubation, partly due to the apparent inability of fire ants to prey upon vireo eggs. We monitored 435 nests without video; field assistants checked the contents of these every 4–5 days. The daily survival rate of these nests was not higher than the rate of nests monitored with video, evidence that video monitoring does not increase nest predation relative to monitoring by human visits to nests.Uso de Video para Observar la Depredación de Nidos de Vireo atricapillusResumen. De 1998 al 2001 monitoreamos 142 nidos de Vireo atricapillus en Fort Hood, Texas. Utilizamos cámaras de video de luz infrarroja para identificar a los depredadores de los nidos. Logramos grabar 59 visitas de depredación (donde al menos parte del contenido de los nidos fue removido o destruido); en éstas, 48 nidos fueron depredados. Los principales depredadores de los nidos de V. atricapillus fueron las serpientes y las hormigas de fuego (Solenopsis sp.). Del total de nidos depredados, 18 (38%) fueron depredados por serpientes y 15 (31%) por hormigas. También identificamos otros depredadores como algunas especies de aves (19% de los nidos depredados) y mamíferos (11% de los nidos depredados). A pesar de la campaña intensiva de erradicación de Molothrus ater en Fort Hood, registramos 9 visitas de depredación por parte de hembras de esta especie, pero sólo una de estas visitas resultó en el fracaso del nido. Aunque las visitas de depredación se dieron en cualquier momento, la mayoría (58%) ocurrió durante la noche. La tasa diaria de depredación fue más alta durante la etapa de crianza que durante la etapa de incubación, en parte debido a la aparente inhabilidad de las hormigas de fuego para depredar los huevos de Vireo atricapillus. Durante nuestra investigación, monitoreamos 435 nidos sin cámara de video; los asistentes de campo revisaron el contenido de estos nidos cada 4 ó 5 días. La tasa de sobrevivencia diaria de estos nidos no fue más alta que la de los nidos monitoreados con cámaras, mostrando que el monitoreo con éstas no incrementa la depredación de nidos con relación al monitoreo por visitas personales a los nidos.
