What essential component of the diet is paramount for raising young during the Whinchat's breeding season?
Answer
Protein-rich invertebrates
During the breeding season, the primary biological imperative shifts towards supporting the growth and development of the nestlings. This high-demand period requires food sources that deliver necessary building blocks for rapid growth, which are supplied most effectively by protein. Consequently, the Whinchat heavily relies on an invertebrate feast, consuming arthropods and worms rich in protein. While they eat many things, the need for this specific macronutrient means that the availability of insects, larvae, and worms becomes non-negotiable for parental provisioning and chick survival.
