Summary
The response of the starling to sugar solutions was investigated as this species, which eats sweet fruits, does not prefer sugar solutions according to the literature.
In choice tests using two identical fountains, moderate preference for higher concentrations (0.5 M and 1 M) of glucose and fructose to water was demonstrated. The same concentrations of sucrose were rejected. Lower concentrations (0.25 M and less) of all three sugars were neither preferred nor rejected. In choice tests using two differently coloured fountains the subjects did not generally respond more sensitively to sugar solutions. In learning experiments with differently coloured fountains the starlings developed very marked preferences for 0.5 M glucose and 0.5 M fructose and a corresponding rejection of 0.5 M sucrose in the course of 1–2 days. In a learning experiment with dentical fountains they also developed a pronounced preference; the preference values obtained, however, are higher if secondary cues such as the colour of the fountain or its position are available. In short time tests immediate responses to sugar solutions could not be demonstrated.
The rejection of sucrose is attributed to illness-induced aversion learning, the learned preference for glucose and fructose to the preference according to gain in energy per unit of time as postulated by the optimal foraging theory. Taste sensations play, if any, only a minor role. The learning mechanisms operating in the experiments could be employed by the starling for the selection of fruits.
