The main objective of this study is to estimate the distribution, habitat use, and reproductive status of Mexican spotted owls (Strix occidentalis lucida) in Zion National Park. This information will allow managers to coordinate park activities that potentially conflict with nest sites, roost sites, or brood rearing habitats. Other objectives of this study are to estimate spotted owl food habits and fledgling success, and to compare these findings with other North American spotted owl populations.

Abstract Understanding the mechanisms causing temporal variability in demographic parameters is essential to understanding fluctuations in populations. As part of a long-term demographic study, we evaluated influence of climate on Mexican Spotted Owl (Strix occidentalis lucida) annual survival and reproduction in two study areas, one in Arizona and one in New Mexico. Spotted Owl survival in New Mexico and reproductive output in both study areas were positively related to total amounts of precipitation from the previous year, previous winter, or monsoon season. For both study areas, temporal process variation in reproductive output (CV[R] = 51.2 and 75.2% for Arizona and New Mexico, respectively) was greater than that for survival (CV[ϕ] = 12.9 and 7.1% for Arizona and New Mexico, respectively). Precipitation from the previous year explained 73% of σ̂2temporal reproductive output for Arizona owls and precipitation from the previous monsoon explained 42% of σ̂2temporal in reproductive output for New Mexico owls. Precipitation from the previous monsoon season explained 53% of σ̂2temporal in Arizona owl survival and precipitation from the previous winter explained 56% of σ̂2temporal in New Mexico owl survival. The two populations of Spotted Owls we studied appeared to have the same life-history strategy hypothesized for a population of Northern Spotted Owls (S. o. caurina), although the Mexican subspecies apparently responded quite differently to climatic variation.

Strix Occidentalis Lucida

El tecolote moteado mexicano (Strix occidentalis lucida) es una especie amenazada en Estados Unidos y México, la falta de estudios en todo su ámbito de distribución y la creciente pérdida de hábitat, limita su conservación. El objetivo de este estudio fue estimar la distribución potencial de esta especie en una porción del centro de México. Para ello, se usó el algoritmo Maxent y el software ArcMap utilizando 21 registros de presencia del tecolote, 19 capas bioclimáticas, 4 capas del modelo digital de elevación, una de cobertura, y una de vegetación y uso de suelo. La cobertura, vegetación, elevación, precipitación y temperatura fueron las variables que más explicaron el modelo de distribución potencial. Zacatecas presentó la mayor superficie con muy alta probabilidad de distribución. Maxent parece ser una herramienta útil para definir la distribución de Strix occidentalis lucida; sin embargo, para validar sus resultados, es necesario comprobar en campo la presencia de esta especie en los sitios indicados por este modelo.
