But those birds has evolved by millions of years. Avian flight may have started 
as 
easyer way of attacking, but whitin the millions of years which has gone, it 
has been 
used for a lot of other things. Like escaping. After evolving wings, many birds 
has 
evolved away from flying whith them, like penguins, cormorants birds, ratites 
and some 
other birds that are loosing the ability to fly, and fherefore flies badly. 

But we have examples of birds that uses the flight as attacking too, like the 
hawks. 
Maybe dinoes like "Rahona" attacked the same way, from sitting in a tree - that 
is my 
point.
