Abstract: | Birds move between breeding locations to gain a better territory, avoid competition or reduce the deleterious effect of inbreeding.
We investigated breeding site fidelity in a small European passerine, the penduline tit (Remiz pendulinus). This species has an exceptionally diverse breeding system, in which both males and females may have up to 5–7 mates in
a single breeding season, and the eggs are incubated by a single parent: either the male or the female. We investigated the
movements of males and females within three breeding seasons in Southern Hungary (2002–2004). Males moved for shorter distances
between breeding sites (116 m, 63–333 m; median, lower quartile–upper quartile) than females (942 m, 415–2,382 m). Movements
of males and females were consistent between years, and they were repeatable between subsequent nests of males, but not of
females. Taken together, our results suggest that adult male penduline tits are more site-faithful than adult females. We
suggest that this difference has an implication on their breeding ecology since male parental behaviour (desert/care) is expected
to be influenced by local mating opportunities, whilst female parental behaviour is likely to depend on the mating opportunities
in a large area around their breeding site. |
