Abstract We investigated the occutrence of mate switching in the common quail, a non‐monogamous species with a temporal pair bond but without either male parental care or territoriality. The study was carried out throughout the breeding seasons of 1993–95 in Mas Esplugues (Catalonia, Spain) by monitoring 28 radio‐tagged couples and 17 radio‐tagged unpaired males. Agonistic interactions between males inside funnel traps containing a female were also recorded. Mate switching within the laying period occurred in 72% of the females, and new partners always had a higher body condition index than old partners. Agonistic interactions inside the funnel traps also showed that successful males had a better body condition index than losers. These results, along with the observed mate‐guarding behaviour of females by their partners throughout the laying period, a highly male‐biased sex ratio (five males per female), the lack of territoriality of males and the expected difficulties which unmated males experience in finding pairs, suggest that mate switching is not induced by paired males. Moreover, the constant inflow of new males observed throughout the fertile period of the female and the low costs stemming from mate change strongly support the idea that it is paired females who induce mate switching, in order to improve their fitness by mating with the best quality male available at every moment of their fertile period.
