Can you tell me what to feed the birds here in Afghanistan? They are small, a little like finches.

Most seed eating birds will eat sunflower seeds. Finches like a variety of seeds in the wild. At feeders Niger thistle seed and sunflower seed are the most popular. I found more information about birds in Afghaninstan on wikipedia: http://en.wikipedia.org/wiki/List_of_birds_of_Afghanistan#References
