Birding Alaska

Marbled Godwit Limosa fedoa beringea, Mariner Lagoon, Homer, 19 October 2009.

The beringea subspecies of Marbled Godwit breeds near Ugashik Bay, on the north side of the Alaska Peninsula.  It is an uncommon spring migrant in Homer and other south coastal Alaska locations.  In the fall, however, there are very few Alaskan records of the species after the birds leave their breeding grounds, suggesting that their southbound migration is a direct overseas flight from the Alaska Peninsula to their wintering grounds in the Pacific Northwest.  This Marbled Godwit, present in Homer at the base of the spit since the 18th and seen again today (21 October), is the first fall record for Homer and one of very few for the Kenai Peninsula.  It is probably the latest fall record for Alaska.

The diversity and numbers of shorebirds moving through Homer were impressive this weekend for the 17th Annual Kachemak Bay Shorebird Festival, May 7-10.  Here are a few shots from the weekend.

Black-bellied Plover Pluvialis squatarola, Short-billed Dowitcher Limnodromus griseus, Dunlin Calidris alpina and Bar-tailed Godwit Limosa lapponica, Green Timbers, Homer, 10 May 2009.

This photo captures one of the most incredible mixed flocks of shorebirds I’ve ever seen. In the flock but not photographed here were Red Knots, Western and Least Sandpipers, a Marbled Godwit and a Pacific Golden-Plover.  Black Turnstones were on the same beach just a bit further down.

Red Knot Calidris canutus, Green Timbers, Homer, 10 May 2009.

Red Knots are uncommon to rare migrants through Homer.  A single bird was reported on Saturday and at least 13 were on the Homer Spit today, 10 May.

This Bar-tailed Godwit was first found on the Homer Spit on Thursday and seen daily through the weekend.  Marbled and Hudsonian Godwits were also seen during the festival.

A lone Sanderling Calidris alba, Western Sandpiper Calidris mauri and Dunlin, Mud Bay, Homer, 8 May 2009.

This Sanderling (the larger pale bird in the center), still in winter plumage, was the only one reported for the weekend.

Black-bellied Plovers, Green Timbers, Homer, 10 May 2009.

There was no shortage of Black-bellied Plovers along the Homer Spit this weekend.

This Marbled Godwit is seperated from other godwits by it’s uniform cinamon brown coloration.  Here it dwarfs the much smaller Westerns and Dunlins but it’s also larger than both Hudsonian and Bar-tailed Godwit.
