摘要

摘要：鲱鱼从人类身上偷取食物的行为随着人类食物供应的增加而增加，但与任何食物偏好无关。海鸥在偷窃时获得的食物明显多于在觅食时获得的，大多数人的反应是中性的，这表明偷食物对城市鲱鱼来说是一种低风险、高回报的策略。

Factors associated with Herring Gulls Larus argentatus stealing food from humans in coastal towns

ABSTRACT Food stealing from humans by Herring Gulls Larus argentatus increased with human food availability but was not associated with any food preferences. Gulls obtained significantly more food when stealing than when scrounging, and the response of most people was neutral, suggesting that food stealing is a low-risk, high-reward strategy for urban Herring Gulls.
