Revākhaṇḍa ascribed to the Vāyupurāṇa (RKV) 8.3

8.3

dhyāyamānastataḥ kāle apaśyaṃ pakṣiṇaṃ param /
hārakundendusaṃkāśaṃ bakaṃ gokṣīrapāṇḍuram //

While thus meditating in that time, I saw an extraordinary bird: / a crane resembling a string of pearls, the kunda flower, and the moon, white as cow's milk.
