Translation: 
Sometimes the honeybees in Vṛndāvana became so mad with ecstasy that they closed their eyes and began to sing. Lord Kṛṣṇa, moving along the forest path with His cowherd boyfriends and Baladeva, would then respond to the bees by imitating their singing while His friends sang about His pastimes. Sometimes Lord Kṛṣṇa would imitate the chattering of a parrot, sometimes, with a sweet voice, the call of a cuckoo, and sometimes the cooing of swans. Sometimes He vigorously imitated the dancing of a peacock, making His cowherd boyfriends laugh. Sometimes, with a voice as deep as the rumbling of clouds, He would call out with great affection the names of the animals who had wandered far from the herd, thus enchanting the cows and the cowherd boys.
Purport: 

Śrīla Sanātana Gosvāmī explains that Lord Kṛṣṇa would joke with His friends, saying, “Just look, this peacock does not know how to dance properly,” whereupon the Lord would vigorously imitate the peacock’s dancing, causing great laughter among His friends. The bees in Vṛndāvana would drink the sap of the forest flowers, and the combination of this nectar and the association of Śrī Kṛṣṇa made them mad with intoxication. Thus they closed their eyes in ecstasy and expressed their satisfaction by humming. And this humming was also expertly imitated by the Lord.
