Abstract
Natal dispersal allows individuals to reach suitable

breeding sites. The effect of present plant phenology

as a cue for dispersal into areas with favourable stages of

development has been well established across avian and

mammalian taxa. However, the effect of past experience is

less understood. We studied the effect of past and present

phenology of the environment on the direction and distance

of natal dispersal in a passerine bird, the pied flycatcher

(Ficedula hypoleuca). We monitored spring settlement of

local recruits in six nest box plots along a 10-km stretch of

a south-north gradient of plant and caterpillar food development.

We found that males used both past experience of

caterpillar phenology from early life and actual plant phenology

during the recruitment season as independent cues

for breeding settlement. Males that had experienced a mismatch

with the caterpillar food peak as a nestling, and/or

those that arrived late in the spring in the recruitment year,

moved north of their natal site, whereas males that had

experienced a better match with the caterpillars as a nestling,

and/or those that migrated earlier in the spring, settled

at a similar site or more to the south. In females, no such effects were found, suggesting that the usage of phenological

cues is sex specific. In summary, tracking environmental

phenology by natal dispersal may represent an effective

mechanism for settling in new favourable areas, and may

thus potentially cause rapid change of a species’ geographical

breeding range in response to climate change.
