“Tamra’s themes are air, earth, nature, health, longevity, devotion, wishes and relationships. Her symbols are feathers and birdseed. In Hindu tradition, this Goddess was the ancestor of all birds, She can teach us their special language, which often bears communications from the divine. As the consort of the turtle god, Kashyapa, She also represents a potent union between earth and air elements.
People in Nebraska spend six weeks watching the cranes who rest and feed here during the migratory season. This region of the United States boats the largest group of sand hill cranes, about fifty thousand birds.
Magically speaking, these creatures represent health, longevity and devotion. Visualise a crane residing in your heart chakra anytime you need improved well-being.
Birds offer numerous magical applications. For warmth in a relationship, scatter feathers to the winds with your wish. The birds will use the feathers in their nests, symbolically keeping your nest intact and affectionate.
Or, disperse birdseed while thinking of a question. As the birds fly away, watch their movement. Flight to the right indicates a positive response; to the left is negative. If the birds scatter, things are iffy. If they fly straight up overhead, a heartfelt wish is being taken to Tamra.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
Yet, another Goddess that proved to be elusive. Apparently, She was one of the 13 daughters of the Prajapati Daksha (Aditi, Diti, Kadru, Danu, Arishta, Surasa, Surabhi, Vinata, Tamra, Krodhavaśā, Ida, Khasa and Muni) all of whom were given in marriage to Kashyapa. The only real mention I found of Her was in the Agni Purāṇa (a genre of Hindu religious texts, containing the descriptions and details of various incarnations (avatars) of Vishnu). It states, “Kasyapa was the son of Marici, who was the son of Brahma. Kasyapa’s wife Tamra had many daughters like Kaki, Syeni, Bhasi, Grdhrka, Suki and Griva. From Kaki were born the crows in the world.” 
“Tamra had six daughters. These were the mothers of the birds and of goats, horse, sheep, camels and donkeys.”
