1. Predictions from existing models on 'ideal free distribution of unequal competitors' were tested by comparing the intake rates of the birds in relation to their bowl preferences.

2. Three types of distributions across two patches (1 and 2, where 1 provides higher food production rate than 2) were tested: truncated (H

), semi-truncated (H

3. The birds were studied in groups of six. They were fed by presenting two bowls containing mealworms, one bowl had twice the food-input rate of the other.

4. Four birds visited the high-density bowl more often than the low-density bowl, whereas the other two birds showed no or opposite preferences.

5. The semi-truncated distribution was the only distribution that could not be rejected by any criteria.

6. When members of the experimental group were exchanged, the changes in individual intake rates suggest that the intake rate is related to each individual's quantitative competitive ability rather than to the individual's rank.
