Inbreeding and divorce in blue and great tits
Article Abstract:
Inbreeding depression has been demonstrated in several wild bird populations, and such depression should result in selection favouring mechanisms to avoid inbreeding. In blue tits, Parus caeruleus, matings between close relatives are linked with fitness costs, which may be hard to avoid. A long term population study on blue and great tits was undertaken and it was found that both male and female blue tits benefited from divorce when some of their clutch failed to hatch.

Patch time allocation and patch sampling by foraging great and blue tits
Article Abstract:
Research into the allocation of searching time amongst food patches in the home ranges of breeding great tits, Parus major, and blue tits, Parus caeruleus, is presented. It was found that great and blue tits devoted a large proportion of their search time to the most profitable trees close to their nests.
