Then again; the larger the bird, the further it could have traveled to forage 
for food. Larger birds 
may also have been able to eat a wider variety of things.

My money would have been on medium-sized generalists, perhaps something about 
the size of a 
pigeon (but with the broad diet of a crow). Tiny birds tend to be more 
specialised feeders, and 
seeds and/or small insects may have been scarce for several years after the 
impact. Anything 
large enough to scavenge from carcasses, or to capture small reptiles or 
mammals, may have 
fared better.
