 >Insley, S.J., Paredes, R. and Jones, I. 2003. Sex differences in razorbill
 (Alca torda) parent-offspring vocal recognition. J. Experimental Biology,
 206 (1): 25-31.
 >We investigated differences in parent-offspring vocal recognition between
 males and females in a natural population of razorbills (Alca torda), a
 long-lived and highly social species of auk (Family: Alcidae). Razorbills
 provide bi-parental care to their chicks while at the nest, after which the
 male is the sole caregiver for an additional period at sea.
 Parent-offspring recognition in razorbills is most challenging once the
 chick becomes mobile, when the chick leaves the nest and goes to sea with
 the male parent. It is during this period when selection pressure acting on
 recognition behaviour is expected to be strongest. As a result, we
 predicted that parent-offspring recognition would be better developed in
 the male parent, that is, show a paternal bias. To test this prediction we
 used vocal playback experiments conducted on breeding razorbills at the
 Gannet Islands, Labrador, 2001. We found (1) most positive responses to
 playbacks (vocal and phonotactic) occurred close to fledging, (2) males
 responded more to calls from their chicks than to calls from strange
 chicks, (3) females responded indifferently to calls from their own or
 strange chicks, and (4) chicks responded more to calls from their male
 parent than to calls from other adult males. The results provide clear
 evidence of mutual vocal recognition between the male parent and the chick
 but not between the female parent and the chick, supporting the prediction
 that parent-offspring recognition is male biased in this species. Such a
 bias could have important social implications for a variety of behavioural
 and basic life history traits such as cooperation and sex-biased dispersal.
