Abstract

Observations of a single nest-building female blue tit (Parus caeruleus) supported the hypothesis that increasing proximity of domestic cats (Felis domesticus) to the nest box increases time spent scanning the nest site area. A hypothesised decrease in time in the nest box with increased cat proximity was not confirmed. A reason for this is forwarded, and differences in time spent in/and in the vicinity of the nest box reflecting position of the nest visit in a bout, and threat posed by individual cats are discussed.
