Abstract

Two hundred twenty-five observations of melanistic (melanic) deer in 3,875 sightings of white-tailed deer (Odocoileus virginianus) were made on mobile census lines, driving roadside counts, and stationary blinds from August 1988 to February 1996 in eight counties in central Texas. The highest incidence of melanic deer (21%) at 11 census lines in a region of approximately 8,250 $km^{2}$ occurred in eastern Hays and western Travis counties. Mean frequency of melanic deer on the 11 census lines was 8.5%. Because of highly variable pelage color in white-tailed deer in central Texas, semi-melanistic deer were also identified. This is the only known population of white-tailed deer in North America with a sizable melanic component. /// Se hicieron doscientas veinticinco observaciones de venado melánico de 3,875 observaciones de venado cola blanca (Odocoileus virginianus) en un censo de líneas móviles, en conteos a lo largo de caminos, y desde escondites fijos entre agosto de 1988 y febrero de 1996 en ocho condados del centro de Texas. La mayor incidencia de venados melánicos (21%) se dió al este del condado de Hays y al oeste del condado de Travis, en 11 líneas de censo en una región de aproximadamente 8,250 km^{2}. La frecuencia promedio de venados melánicos en las 11 líneas de censo fue de 8.5%. Debido a la gran variación de color del pelaje en los venados cola blanca en el centro de Texas, los venados semi-melánicos también fueron identificados. Esta es la única población de venado cola blanca en Norteamérica que tiene un componente melánico de tamaño considerable.
