Seasonal and age-related differential mortality by sex in the Mantled Howler monkey,Alouatta palliata

Age-specific, differential mortality occurs between male and female mantled howler monkeys, Alouatta palliata,on Barro Colorado Island, Panama. A peak in mortality between 5 and 7 years is seen in males but not infernales. Dates when howler cadavers have been found suggest a seasonal mortality, with peaks in July and perhaps also in December through January.
