Oshawa Second Marsh and vicinity birding report, for the  SEPTEMBER 5 -
SEPTEMBER 11, 2003 period.

A first year BALD EAGLE seems to have been trying to join the DOUBLE-CRESTED
CORMORANT flock. It has been observed sitting in the Second Marsh barrier
beach willows with Cormorants. On the 5th is was perched on a stump on the
west side of the marsh. On a nearby adjacent stump several cormorants
perched oblivious to, or now accepting the eagle. 2 MERLINS (5th and 9th)
have set up temporary territories around the marsh. They can been seen
chasing shorebirds or making dashes from their perches to catch dragonflies.
Other Raptors seen this week around the marsh include OSPREY, NORTHERN
HARRIER, SHARP-SHINNED HAWK, and COOPER'S HAWK.
Some mudflats have now emerged between the islands of new growth cattails in
the central and northern areas of the marsh. Species seen this week include
both GREATER and LESSER YELLOWLEGS, PECTORAL SANDPIPERS, AND SOLITARY
SANDPIPER. An extensive band of rotting algae has washed up on the shore of
Lake Ontario. It extends from the eastern side of McLaughlin Bay Wildlife
Reserve to the middle of the barrier beach in Darlington Provincial Park.
Shorebirds numbers and diversity have fluctuated daily. On Sept 9 there were
7 species there including 9 SANDERLING, 4 BAIRD'S SANDPIPER, and a immature
RUDDY TURNSTONE. On Sept 11 there was one 1 SEMIPALMATED PLOVER and 2 LEAST
SANDPIPERS.
Waterfowl numbers have soared this week in the Second Marsh. On the 5th
there were approx. 700 birds, rising to 2500 on the 9th, and then down to
850 on the 11th. On the 9th 1065 MALLARDS, 411 BLUE-WINGED TEAL, 278
GREEN-WINGED TEAL, 244 GADWALL, and 208 NORTHERN SHOVELERS were counted
among 14 species of waterfowl.  Also observed this week were small but
increasing numbers of AMERICAN WIGEON, NORTHERN PINTAIL, AND AMERICAN BLACK
DUCK. There were single RUDDY DUCK and HOODED MERGANSER  and 2 LESSER SCAUP
observed there on the 5th.
One COMMON LOON was seen in Lake Ontario off the McLaughlin Bay Wildlife
Reserve on the 11th. A lone PIED-BILLED GREBE continues to been seen in the
marsh. AMERICAN COOTS (9 on the 11th) and COMMON MOORHENS (3 on the 5th) are
becoming more visible. The post breeding dispersal of herons is evident in
the marsh, with GREAT BLUE HERONS (25-11th), BLACK-CROWNED NIGHT HERONS
(26-5th),
GREEN HERON (4 -5th) and a GREAT EGRET which has been seen daily in the
Second Marsh.
 Several large flocks of westward bound BLUE JAYS  were observed passing
