Redwood Creek Winter Birding

The Mouth of Redwood Creek Is A Hotspot for Cold Weather Birds

This spring (2018), at Redwood National and State Parks, local bird watchers - commonly called “birders” - have been a twitter over several unusual or rare birds sighted at or near the Redwood Creek estuary. The first was a very rare bird for California, a female Steller’s Eider (duck) seen on March 7th, 2018 by Jeff Allen (who found the Common Pochard in 2016 at Freshwater Lagoon) offshore near the mouth of Redwood Creek. The bird was sighted again on March 10th , 2018 by a few birders, and seen once more on March 14th by a single birder. If confirmed, it would only be the 4th record of this species for all of California.

An Iceland Gull was spotted at the mouth of Redwood Creek on the March 11 in a large mixed flock of gulls. This species is separated into 3 subspecies, with the Thayer’s Gull being the one most commonly seen here. This individual was of the “Kumlien's" form, found generally along the east coast of the United States and nesting in northeastern Canada.

An immature Tundra Swan was spotted on the March 12th by Redwood National and State Parks (RNSP) biological science technician, Heather Brown. The swan was feeding along the edge of the south levee of Redwood Creek. Normally these birds can be found at the Humboldt Bay Wildlife Refuge in winter. Seeing one in fast moving water is unusual, and it is only the 8th record of this species within RNSP lands.

On this same day, Heather also spotted two Bonaparte’s Gulls and four Black-legged Kittiwakes before the mixed gull flock at the mouth of Redwood Creek flushed. Another local birder/biologist was able to identify 10-11 kittiwakes before they flushed. Bonaparte’s Gulls nest in Canada and into Alaska. They are found along the west coast of the United States down to Baja California in the winter. Stan Harris, in his book, Northwestern California Birds, calls them a common migrant, with peak numbers in April.
Black-legged Kittiwakes winter out to sea “along the outer ocean shelves and deep water habitats” (USFWS) of the west and east coasts of the United States. They nest in limited areas of Alaska, especially along the Aleutian Islands as well as along a limited area of eastern coastal Canada. Black-legged Kittiwakes, according to Stan Harris’s book, are called an uncommon migrant, with peak numbers showing up in early spring, and “almost never seen shoreward of the immediate surf”.
All in all, a stellar few days for our local birding community here in Redwood National and State Parks.
