| repeatability of nest morphology in african weaver birds. | it is generally assumed that birds build nests according to a genetic 'template', little influenced by learning or memory. one way to confirm the role of genetics in nest building is to assess the repeatability of nest morphology with repeated nest attempts. solitary weaver birds, which build multiple nests in a single breeding season, are a useful group with which to do this. here we show that repeatability of nest morphology was low, but significant, in male southern masked weaver birds and no ... | 2010 | 19846449 |
