SB 10.67.11
dustah sakha-mrgah sakham
arudhah kampayan druman
cakre kilakila-sabdam
atmanam sampradarsayan
Translation:
The mischievous ape climbed a tree branch and then revealed his presence by shaking the trees and making the sound kilakila.
Purport:
The word sakha-mrga indicates that the ape Dvivida, like ordinary apes, was naturally inclined to climb trees. Srila Prabhupada writes: “This gorilla by the name Dvivida could climb up into the trees and jump from one branch to another. Sometimes he would jerk the branches, creating a particular type of sound — kilakila — so that Lord Balarama was greatly distracted from the pleasing atmosphere.”
