Mostly they feed insects, though most especially in the firts few days after hatching, but they can also rear young on green, unripe seeds - field studies have shown some to rear young entirely on milky unripe wheat. Unripe seed has been shown by laboratory studies (various universities - data published on the www) to be an adequate food for young for 2 reasons - it is very quickly digested and it contains elevated essential amino-acid levels compared to ripe, dry seed.
