What Does the Willcocks's Honeyguide Eat?
The Willcocks's Honeyguide has a unique diet primarily consisting of insects, particularly bees and their wax. This specialization allows it to exploit a niche food source that many other birds avoid. The bird uses its sharp beak to access hives, consuming larvae, bees, and wax. Wax is a rare dietary component in the avian world, but the Willcocks's Honeyguide's digestive system is specially adapted to break it down.
Seasonal changes do affect the diet to some extent. During the wet season, when insects are more abundant, the bird's diet becomes more varied, including other insects like ants and termites. The bird employs an active foraging technique, moving swiftly through the forest canopy, gleaning insects from leaves and branches. It also occasionally follows larger mammals or other birds to exploit disturbed insects.
Prey size typically ranges from small larvae to adult bees and insects around 1 to 2 centimeters in length. The Willcocks's Honeyguide feeds throughout the day, with peaks in activity during the early morning and late afternoon, times when insects are most active.
