Bird Family :Picidae - Wrynecks, Piculets, Woodpeckers, Flamebacks & Yellownapes
Red Data Status :Least Concern
Remarks :Here is my observation and explanation
1. It is PECK: After each fresh peck the tree reacts to this intrusion by producing sap in order to plug the holes. SAP contains water, sugar and minerals. Sap attracts insects that the woodpeckers harvest, as they need protein as well as sugar.
2. It is not DRUM: Peck and drum are two different behaviours. I heard the drumming of a Fulvous-breasted Woodpecker at the top of a dead hollow bamboo during my observation. This is probably to attract its partner or to protect its territory.
3. Body balance: Unlike most birds which have three forward toes and one hind toe, woodpeckers have two toes in front and two in back. This toe arrangement, along with stiffened tail feathers, allows the birds to lean back and pound away.
4. It is not a nest: They prefer dead tree for the nest and rather it is 'sap well'. The wound was 2 ft above the ground
5. Tolerance distance: After more than half an hour I decided to measure the tolerance distance and it was 11 ft.
6. It is SPRING: They normally do this in late winter or in spring. - SM
