Optimal prey selection in the great tit (Parus major)

Realized heritability of personalities in the great tit (Parus major).

Behaviour under conditions of mild stress shows consistent patterns in all vertebrates: exploratory behaviour, boldness, aggressiveness covary in the same way. The existence of highly consistent individual variation in these behavioural strategies, also referred to as personalities or coping styles, allows us to measure the behaviour under standardized conditions on birds bred in captivity, lin...

Correlates of Variation in Flight Feather Quality in the Great Tit Parus major

Partitioning of Phenotypic Variance in Life-history Traits in the Great Tit, Parus major

Intensity of nest defence is related to offspring sex ratio in the great tit Parus major.

Nest-defence behaviour of passerines is a form of parental investment. Parents are selected, therefore, to vary the intensity of their nest defence with respect to the value of their offspring. Great tit, Parus major, males were tested for their defence response to both a nest predator and playback of a great tit chick distress call. The results from the two trials were similar; males gave more...

Spring phenology does not affect timing of reproduction in the great tit (Parus major).

Many seasonal breeders adjust the timing of reproduction in response to year-to-year variations in supplementary environmental cues, amongst which ambient temperature is thought to be most influential. However, it is possible that for species such as the great tit (Parus major L.), phenological cues from sprouting vegetation and the consequent abundance of invertebrate prey, although dependent ...
