A number of wild birds have been released back into their natural habitat after being treated at a resort in the northwestern city of Tabriz on Thursday.

Hosting over 600 species of birds, Iran is a climatically rich country, so it is said that the number of bird species in Iran is higher than in the whole of Europe. 

A wide range of wetlands is the reason behind migratory birds choosing Iran for an annual wintering habitat, as a large number of birds fly a thousand miles each year to benefit from this rich climate.
