What type of food material sees greater inclusion in the Uguisu's diet outside the immediate breeding phase?
Answer
Small berries or fruit pulp when insects become scarce
The Uguisu demonstrates dietary flexibility as a survival mechanism when its preferred food source becomes difficult to acquire. Outside of the high-energy demands of breeding, particularly during migration or the non-breeding winter months when flying insects decline significantly, the bird may incorporate more plant material into its consumption. Observations suggest a greater inclusion of small berries or the pulp derived from fruit when insect availability drops, allowing the warbler to maintain necessary energy levels during periods of food scarcity, especially in colder climates.
