What management technique contrasts the House Sparrow's preference for ground feeding?

Answer

Offering preferred seeds in hanging or tray feeders inaccessible to the most aggressive ground skirmishes.

Using elevated feeders, such as hanging tube feeders, contrasts with their ground preference and can help differentiate species behavior, as House Sparrows actively choose the lowest available food source.
