Abstract: | The lesser kestrel (Falco naumanni) is considered a socially monogamous species in which extra-pair copulation occurs at a low rate. A wide study of extra-pair
mating behaviour carried out on this species found that mated females do not solicit extra-pair copulation and reject all
copulation attempts elicited by extra-pair males. In fact, the infrequent instances of extra-pair fertilization found were
attributed either to re-mating after divorce, or polygyny. Here I describe an observation indicating that females also promote
and accept promiscuous mating, attaining and consummating extra-pair copulation. I suggest the possibility that promiscuous
behaviour could vary among different populations in this species, as it has not yet been reported, in spite of the extensive
work performed in this respect. |
