Woodpeckers roost and nest mostly in #tree cavities (excavated or natural). Nesting and roosting cavities are slightly larger than the width of the bird and are either round, rectangular, or gourd-shaped. Woodpeckers choose their holes carefully, tending to look for dead trees or snags that have a hard outer shell and a softer inner cavity. The diet of a woodpecker includes ants, termites, beetles and their larvae, caterpillars, spiders, other arthropods, bird eggs, nestlings, small rodents, lizards, fruit, nuts and tree sap. #Woodpecker has a unique sense of excavating a productive hole where the can hear sounds from inside the timber. Having hammered a hole into the wood, the prey is extracted by use of a long, barbed tongue.

The picture here depicts the feeding behavior of a woodpecker excavating holes in order to gain food and in turn play the ecological role to keep trees healthy and saving them from mass infestations. Photo taken during a hike in Aravallis.
