Valmiki Ramayana Kishkindha Kanda Sarga 1 Shloka 15

शैलकन्दरनिष्क्रान्तः coming out of the mountain caves, अनिलः wind, मत्तकोकिलसन्नादैः with the voices of intoxicated cuckoos, पादपान् tress, नर्तयन्निव as if making them dance, प्रगीत इव च and as if singing well.

"As if the trees are dancing to the music of the cuckoos and to the sound of the wind coming out of the mountain-caves.
