generally expected in peripheral populations. If food is more difficult to find in the periphery of the distribution range, foraging trips (off-bouts) would be expected to be longer in northern and southern populations. The great tit ( Parus major ) is a widespread passerine that breeds in wooded areas

when the optimal solution regarding e.g. a life history trait differs between co-operating individuals of different sex. When deciding a con ict is not instantaneous,some form of negotiation can be expected to evolve. In great tits, Parus major , a sexual con ict exists over the number of clutches

In the great tit Parus major , individual hue of the yellow breast coloration, an environmentally influenced trait, showed a significant correlation between years in spite of repeatability between years being very low. However, the
