Valmiki Ramayana Sundara Kanda Sarga 14 Shloka 10

उत्पतद्भिः by the flying ones, द्विजगणैः by flocks of birds, पक्षैः with wings, समाहताः hit, सालाः sala, अनेकवर्णाः of different colours, विविधाः many, पुष्पवृष्टयः showers of flowers, मुमुचुः let loose.

As the birds flew away, the trees hit by the wings of birds showered flowers of different colours.
