Sea Life (edit 2)

[TranquillityBase]

I sit on the Delaware shore as
my toes investigate the sand.  Above,
 
Osprey soar on grey-white speckled wing.              with apologies to Semi, I'd add an "and":  "grey and white wings" and does "osprey" need capitalization?
Tucked, they plunge with fierce precision                     
 
piercing the shimmering blue;
reborn they rise, a meal of silver gleam        gleams? (and maybe move it to beginning of next line)
 
tight in their talon.            talons?
The raptors climb on 
 
amid the shriek and holler
of sandy, tanned children.
 
Salted in surf, they eat till they’ve            
had their fill, sustained by every wave.     I read these lines as referring to both the children and the osprey.  If so, maybe something besides "eat".

Interesting juxtaposition of the killing and playing.  Idyllic but not overly so.
