摘要：Horned Larks (Eremophila alpestris L.), sampled during the first 2 weeks of alkali bee (Nomia melanderi Cockerell) emergence at bee nesting sites in 2 alfalfa seed-growing regions in central Nevada, ate significantly more male than female alkali bees. Exploitation rates suggest that individual Horned Larks consume 10 to 200 alkali bees per day and feed an additional 300 to 1000 bees per day to nestlings nestlings.
