चक्रे किलकिलाशब्दमात्मानं सम्प्रदर्शयन् ॥ ११ ॥
ārūḍhaḥ kampayan drumān
The mischievous ape climbed a tree branch and then revealed his presence by shaking the trees and making the sound kilakilā.
The word śākhā-mṛga indicates that the ape Dvivida, like ordinary apes, was naturally inclined to climb trees. Śrīla Prabhupāda 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 — kilakilā — so that Lord Balarāma was greatly distracted from the pleasing atmosphere.”
