FEEDING BEHAVIOR OF BIRDS IN FLOCKS 
Wedge-tailed Shearwater 
v. • • „ 
Wedge tails were observed feeding in two major ways - either sitting on 
wie water and dabbling or flying above the water and diving into the water* 
•Jhen sitting on the water they keep the wings folded, paddle around and put 
their head and neck under water to feed* When flying above the water, they 
dive oo just above the water and put their head and neck under the water® 
During this action their wings are continuously beating. After sitting on 
the water they take off by lifting their heads out of the water and run along

the surface until becoming airborne. The dives were not very deep-- probably 
less than a foot-- and lasted 3 or* I4. seconds or less* Some Wedgetails were 
observed. :to alight on the water, keep their wings beating, or raised above 
their bodies, thrust the head and neck under water, and then take flight 
after a short run*
