What must the diet for Uguisu chicks consist of during the critical breeding season?

Answer

A diet consisting almost exclusively of animal protein and soft-bodied larvae

During the breeding phase, the nutritional demands placed upon the parents skyrocket because they must provision rapidly growing nestlings. For the young birds, survival and healthy development are directly tied to consuming high-energy, high-protein food sources. Consequently, the parents must focus on feeding the chicks a diet composed almost entirely of insects and their soft-bodied larvae. If the local supply of these specific invertebrates is insufficient during this narrow window, the entire reproductive success of the pair is severely jeopardized.
