how many bird-species right after the K-T ?



Is there any estimate of how many species of our feathered friends might have 
survived the big high-five from space, say, within a million years (or less) 
afterwards?  

Is it known for a fact which known groups of birds did not pull through, thus 
lost to descendants alive today?
