"One day, Brahma, the creator of the living entities, beheld his own reflection in the water, and admiring himself, he evolved Kimpurusas as well as Kinnaras out of that reflection."

Srimad-Bhagavatam 3:20:45

"The mention of upadeva-vara refers to inferior demigods like the Gandharvas, Kinnaras and Uragas, who are not exactly demigods but between the demigods and human beings."

Srimad-Bhagavatam 4:3:5-7

"The pacified sages chanted Vedic prayers, the denizens of heaven known as the Gandharvas and Kinnaras sang, the beautiful damsels of the heavenly planets danced, and in this way, at the time of the appearance of Nara-Narayana, all signs of good fortune were visible."

Srimad-Bhagavatam 4:1:54-55

"From the description given in this verse, Garuda appears to belong to the Kinnara planet. The inhabitants of the Kinnara planet have the same features as Garuda. Their bodily features are like those of a human being, but they have wings. The word gita-kirtih indicates that the inhabitants of Kinnaraloka are very expert in singing the glories of the Lord. In Brahma-samhita it is said: jagad-anda-koti-kotisv asesa-vasudhadi-vibhuti-bhinnam. In each and every universe there are different types of planets, and each planet has distinctive features. On the strength of this verse, we can understand that in Kinnaraloka the inhabitants can fly with their wings. There is also a planet, known as Siddhaloka, where the inhabitants can fly even without wings. ."
