We analyze the effectiveness, biases and limitations of a poorly-known emetic, apomorphine, for studying the diet of granivorous birds. Apomorphine was tested on three Fringillids yielding an effectiveness of 43-78%, comparable to that reported for the most common emetic, tartar. The effectiveness of the emetic varied significantly among species, probably due to different physiological tolerances. Older chicks and adults were equally sensitive to apomorphine, but it was ineffective in young… CONTINUE READING
