How do White-crowned Sparrows primarily move debris when foraging on the ground?
Answer
They scratch at leaf litter and dirt backward using both feet simultaneously.
The foraging technique utilized by the White-crowned Sparrow when seeking seeds or insects on the ground is distinctive. They employ a unique method where they use both feet concurrently to kick debris backward away from their body. This action effectively uncovers potential food sources hidden beneath the leaf litter or surface soil. This behavior contrasts with techniques used by some other ground-feeding birds and is crucial for accessing fallen seeds, especially spilled bird food in suburban settings.
