What aspect of body shape contributes to the warbler reputation for being constantly flitting and energetic?

Answer

A relatively slender build

Warblers are consistently described as small songbirds possessing a relatively slender build when compared to other members of their order. This physical conformation directly contributes to their characteristic behavior of being constantly flitting and energetic throughout the foliage. Even when they are momentarily perched, their posture often conveys a sense of alertness, suggesting they are always ready to dart out quickly to capture prey. This general silhouette is light and somewhat delicate, supporting their active, quick-moving foraging style among branches and leaves.
