Merritt Island NWR continues to be a reliable source of up close
and personal opportunities to view wintering shorebirds, ducks
and waders. John Roessler had his camera ready when
we stopped at the beach just beyond the bridge to find a
Marbled Godwit, Limosa fedoa, picking in the wrack
line, apparently unconcerned about multiple humans watching
his/her every move.
The
bird remained close enough for everyone to view field marks,
even without binoculars. One of four Godwits found in
North America, the Marbled Godwit nests near grassy marshes and
is found on beaches, mudflats and shallow pools, walking and
probing the mud with their long, bi-colored bills. At 18
inches tall, with a 30-inch wingspan, the Marbled Godwit is a
large member of the sandpiper group. They breed mainly on
northern Great Plains in the summer and return to coastal
regions during the remainder of the year, sometimes roosting in
large groups. They feed on a
diet of insects, mollusks and crustaceans. While foraging,
they may probe deeply enough into the mud that their entire head
is underwater.
A Ruddy Turnstone,
Arenaria interpres, forages to the right of the Marbled
Godwit. Note the orange leg, white underbelly and dark
chest band that is just barely visible in the photo. This
chunky, short-legged sandpiper sports a bright harlequin pattern
on his back in the summer when it breeds high in the Arctic
tundra. In migration, it is found mostly along the coast,
although large numbers are sometimes found inland, especially
along the Great Lakes. Winter habitat favors rocky
coastlines or beaches covered with seaweed or debris where they
forage by slipping their bills under stones or shells and flip
them over to find food underneath. Several birds may work
together to overturn larger objects. Winter diet includes
barnacles, crabs, mollusks, worms, small fish and even carrion
or food scraps left by human visitors.
