Las hembras de tordos parásitos (género Molothrus) depositan sus huevos en los nidos de otras especies (los hospedadores), los cuales se encargan de incubar los huevos y alimentar a los pichones. El parasitismo ocurre al amanecer y el resto de la mañana sería utilizada para la búsqueda de nidos a ser parasitados los días siguientes. Un problema a resolver por las hembras parásitas es encontrar y recordar la ubicación de nidos apropiados a los cuales retornar posteriormente para poner sus huevos. En este trabajo se estudió el uso del espacio en dos especies parásitas de cría, una generalista, el Tordo Renegrido (Molothrus bonariensis) y una especialista, el Tordo Pico Corto (M. rufoaxillaris) mediante la instrumentación de animales con radio...
