If I understand HP Marjanovich correctly, birds flew
further and further from the water. I'm trying to
figure out why they would do so. So far escape from
predators or a better vantage point on prey has been
proposed. I doubt the latter suggestion is true, since
water refracts light, and would confuse it. 
As for the escape idea What kind of aquatic predators
would prey on little birds?

If they had little need for bipedal running and spent
most of their time getting from here to there by
flying why would they need a tail to counterbalance
the body?
