RESUMO
Registrou-se, numa propriedade agropecuária de Coxilha, RS, o comportamento parental de 3 machos de ema Rhea americana com filhotes de 0 a 30 dias de idade e, num caso, com filhotes de 30 a 60 dias de idade. Houve diferenças entre os machos na freqüência e duração de categorias do comportamento parental e decréscimo do cuidado da primeira para a segunda faixa de idade. O cuidado parental parece estar relacionado ao sucesso reprodutivo dos machos.
ABSTRACT
The parental behavior of 3 male rheas Rhea americana with young aged 0 to 30 days (in one case, also with young from 30 to 60 days of life) was observed in a rural property of Coxilha, Rio Grande do Sul, Brazil. Males differed in the frequency and duration of parental behavior displayed and there was a decrease in this behavior towards older young. Parental behavior seems to influence the reproductive success of rhea males.
