The effect of clutch cooling rate on starling, Sturnus vulgaris, incubation strategy
Article Abstract:
Research into the impact of clutch cooling rate on starling, Sturnus vulgaris, incubation strategy indicates that the energy level of an optimally incubating parent could function as the proximate cue that leads to it ending an incubation bout and leaving the nest. It was established that, contrary to the predictions of standard models of time allocation during incubation, parents devoted a much larger proportion of each 24-hour period to incubating when the rate of clutch cooling was reduced. The parent responds to its own body condition, rather than to the condition of the embryo.

A predator-prey game between bullheads and case-making caddis larvae
Article Abstract:
A study of predator-prey game played between bullheads, bottom-dwelling freshwater fishes of Sweden, and caddis larvae reveals that the larvae feigned dead for longer times than the waiting time taken by the bullheads. Thirty two percent of the larvae waited longer than the most persistent of the bullheads. Waiting time of larvae increased with the increase in the frequency of the attacks. A game theory model war of attrition was used for the study.

The effect of intraspecific competition on prey load size in the European starling, Sturnus vulgaris
Article Abstract:
Experimental study of the factors influencing prey load size in the European starling, Sturnus vulgaris, shows that increasing the level of intraspecific competition at feeding sites reduces the number of prey carried by starlings to the nest. Conspecific proximity is crucial for determining the load size during foraging. Load size reduction decreases the rate of provisioning by parents to the offspring.
