Abstract:

The black-capped vireo is an endangered species that resides at Fort Hood, TX during the summer breeding season. A 3-year ecological status survey of the black-capped vireo was conducted on Fort Hood from 1987 through 1989 as part of the effort to fully comply with the Endangered Species Act. Part II in this series focuses on habitat and Part III on population and nesting ecology. Approximately 280 adult vireos were documented during 1989. Colony sites were situated primarily in hardwood scrub habitat ranging from 5 to 30 years of age. A disproportionately large proportion of the population was located within the live fire training area. Territory size averaged 3.6 ha overall, ranged from 1. 88 ha to 7.04 ha by colony site, and varied significantly among years. Colony sites were associated with certain geologic, soil, elevation, slope, and aspect features. A potential vireo habitat map was developed based on these associations. A training intensity map of the installation helped to define areas of likely conflict between the vireo and military maneuver training.
