Electrocutions are thought to affect avian populations in Asia, but regional research has not been widely disseminated. In this study, we sought to identify whether power lines in rural India were involved in avian electrocutions and, if so, to identify at-risk species and problematic configurations, and to develop a predictive model. To collect data, we visited power poles to search for avian carcasses. We recorded six variables at each pole: line voltage, insulator configuration, conductor separation, jumper count, surrounding habitat, and presence of an avian carcass. We used multivariate logistic regression to model the probability that an avian carcass was found. We surveyed 15 line segments supported by 675 poles, and found 162 carcasses. We found carcasses of five raptor species, including Eurasian Kestrel (n  =  5; Falco tinnunculus) and White-eyed Buzzard (n  =  4; Butastur teesa), though passerine carcasses were more numerous. All modeled variables contributed to the probability of finding a carcass; however, only pin height and jumper count were important contributors to the averaged model. Specifically, carcasses were most common beneath poles supporting jumpers and beneath tangent poles with low center pins. This is similar to another recently completed electrocution model from California, U.S.A., where jumpers and grounding were key predictive variables. There is an ongoing effort to provide electric power to all rural areas in India. Unless poles are retrofitted to minimize electrocution risk, avian electrocutions are likely to increase as power delivery expands. With the simple model we provide, personnel with minimal training can report the results of surveys quantifying electrocution risk, and help utilities prioritize retrofitting dangerous poles. ELECTROCUCIONES DE AVES EN EL OESTE DE RAJASTHAN, INDIA Las electrocuciones de aves son documentadas regularmente a lo largo del mundo. Se piensa que las electrocuciones afectan a las poblaciones de aves en Asia, pero las investigaciones a nivel regional no han sido difundidas ampliamente. En este estudio, buscamos identificar si las líneas de electricidad en la India rural estuvieron involucradas en electrocuciones de aves y, de ser así, identificar las especies en riesgo y las configuraciones problemáticas, y desarrollar un modelo predictivo. Para colectar datos, visitamos postes de electricidad en busca de cadáveres de aves. Registramos seis variables en cada poste de electricidad: voltaje de la línea, configuración del aislante, separación de los conductores, número de puentes eléctricos, hábitat circundante y presencia de un cadáver de ave. Utilizamos regresiones logísticas multivariadas para modelar la probabilidad de encontrar un cadáver de ave. Muestreamos 15 segmentos de cable sostenidos por 675 postes y encontramos 162 cadáveres.
