Presents a theoretical framework in order to understand how the relationship between male parental care and paternity is dependent on the relationship between male parental care and offspring recruitment. When there is an S-shaped relationship between offspring recruitment and the parental care of a single male, the authors predict a threshold relationship between male parental care and paternity. Tree swallows Tachycineta bicolor, monogamous dunnocks Prunella modularis and red-winged blackbirds Agelaius phoeniceus may follow this pattern. Alternatively, when there is a concave-down relationship between offspring recruitment and male parental care, they predict a continuous (gradual) decline in male parental care in response to decreasing paternity. Studies of noisy miners Manorina melanocephala and polyandrous dunnocks suggest this pattern. A predicted adjustment of male parental care in response to paternity must be examined in relation to the effect of male parental care on offspring recruitment and the effect of alternative activities on male fitness. -from Authors
