Anka (Arabic. — a character of Arab-Muslim mythology, wonderful birds created by Allah. They look like the legendary Phoenix.

At first they were created "perfect" and built their nests on Mount Kaf, somewhere in the Caucasus. 

Anka was described as a huge bird, living for about 1,700 years, and just like a Roc bird, capable of lifting an elephant. It was also believed that anki favored people — according to legend, the person on whom her shadow fell was destined to become a king in the future.​‌‌​‌‌​ ​‌​‌‌‌‌ ​​​‌​‌ ​​‌​‌​ ​​‌​‌‌ ​‌​​​‌ ​​‌‌​​ ​​‌​​​ ​‌​​​‌ ​​‌‌‌​ ​​‌​‌​ ​‌​​​‌ ​​‌​‌‌ ​​‌‌‌‌ ​‌​​‌‌ ​‌​‌​‌​ ​‌‌​‌‌​ ​‌‌‌​‌‌ ​​‌‌‌‌
