Full Frontal Feathered Frenzy

BIRDS.



Oh come now, you knew this was coming. It's me we're talking about here.

The Oregon Coast is a phenomenal place for birders and birding. The unique combination of habitats available here makes it possible to see species not as easy to find elsewhere. Additionally, because of its mild climate, it's the perfect place to witness range expansion over time.

Waterfowl are common in the bay and estuaries of of Newport. The main goose found out on the coast is the small, handsome Brant, but heading just a bit inland or a trip to one of Newport's parks (or even a beach) will give you a chance to find the all-too familiar Canada Goose. Dabbling ducks (mallards and the like) tend to avoid the deep salt waters of the harbor, but Northern Pintail and American Wigeon are easy enough to find in the estuaries of Yaquina Bay. Diving ducks are easily found, and present in a spectacular array of colors, shapes, and sizes here. The most easily found are probably the Surf Scoters, whose brightly-colored bill and white eyes starkly contrast with its dark body. Also found here is one of my personal favorites, the Harlequin Duck; the drake's intricately patterned plumage makes him stand out among his fellow sea ducks.

Waterfowl are far from the only water-dwelling birds you find out here. Loons and grebes leave the water only to nest and lay their eggs, otherwise resting on the surface and diving for fish. Pacific, Common, and Red-Throated Loons call the deeper waters of the bay home, occasionally making their way to the Yaquina River. Horned, Red-Necked, and Western Grebes favor similar habitats, but are much smaller.

Cormorants, long-necked fish-eating birds who dive for their prey, are common throughout the area, but tend to congregate on perches with close access to the sea, including underneath the Yaquina Bay bridge and on docks. The thin, delicate-looking Pelagic Cormorants and the whiskered Brandt's Cormorant are the main species found here, but the large Double-Crested Cormorant is about when conditions are fair. A surprise for me came in the form of Brown Pelicans; my sources didn't really indicate they'd stick around for the winter, but they take advantage of food sources here for as long as possible before departing for warmer waters. Unfortunately, this led to a lot of pelicans being battered by storms or just starving, which meant I got to see a lot of pelicans at work.Still, the few that do well can be found with the cormorants out on the jetty or occasionally waiting for scraps tossed out by fishermen.

Without a doubt (and perhaps unsurprisingly), the bird that is most commonly seen on the Oregon Coast  is the gull, in all its forms. These birds tend to get overlooked by many as pests, but are remarkable for how they've adapted to the presence of humans, and have almost as diverse a diet as we do. Most gulls look fairly similar which makes identification a bit of a bother, but by carefully picking through the flocks, one can easily find that there are quite a few species around. The larger Western, Herring, and Glaucous-Winged Gulls dominate the area in winter, though California and Mew Gulls are well-represented as well. In winter, a few rarer gulls can be found, such as the comparatively small Bonaparte's Gull and the dark-hued Heerman's Gull. Further out to sea, it's possible to see Black-Legged Kittwakes, in addition to seabirds of an entirely different order, such as shearwaters, storm-petrels, and albatross.

The vast amount of coastline and mudflats out here allow for a spectacular variety of shorebirds. Loud Black Oystercatcher pairs inhabit rocky intertidal zones, where they use their long bills to pry mussels and limpets off rocks as well as reach into tiny nooks to nab tide pool critters. Semipalmated plovers and Killdeer, meanwhile, are generalists, foraging and resting anywhere they can, including puddles and tennis courts. Diminutive Red Phalaropes gather food in the water, spinning around in little circles, and Sanderlings pick at exposed invertebrates on the beach. Black Turnstones and Surrfbirds are the daredevils of the bunch, foraging on bare rock, just narrowly evading crashing waves.

This area of the Oregon Coast is also home to several species of auks, including the charismatic Tufted Puffin. These birds are typically out at sea during the winter, but a few species can be seen from the shore, including Ancient Murrelets and Pigeon Guillemots, who frequent the Yaquina Bay jetty channel. When the breeding season rolls around, these birds take to isolated sea cliffs for protection from terrestrial predators. Common Murres congregate at Colony Rock next to Yaquina Head lighthouse. Pigeon Guillemots are a little less particular about what kind of isolated habitat to build their nests in, and have even nested under the Yaquina Bay bridge in years past.

Looking perhaps a bit out of place fishing off the South Jetty in Newport, or more likely out on the estuary, Great Blue Herons are abundant across the coast. Other herons, such as egrets and night herons, migrate away from the area, but these lanky fishermen tolerate the rainy, colder months. American coots also frequent these waters.

It isn't all about birds of the sea, though. There are plenty of terrestrial birds that take advantage of the Oregon Coast's mild winters. Raptors and falcons benefit from the abundant food sources and nesting sites. Peregrine Falcons can be found throughout the coastal area, nesting under bridges and on top of buildings, while American Kestrels can be found a little further inland. Ospreys, while absent during the winter, nest on various platforms across the city. Northern Harriers and Red-Tailed Hawks also do well here, in addition to a bird that has recently expanded into the area, the Red-Shouldered Hawk. Bald Eagles are a welcome sight, and thrive on the plentiful sources of fish. Naturally, Turkey Vultures can be found, but not during the winter.

Owls are also well-represented out here. Great Horned, Northern Pygmy, Western Screech, Barred, and Northern Saw-Whet Owls are able to exploit food sources year-round. Visiting owls also find their way to the coast, including the fierce-looking Short-Eared Owl, the majestic Snowy Owl, and the quirky Burrowing Owl. I was incredibly lucky to spot a Burrowing Owl in December, as they're somewhat of a rarity in the area.

The Oregon Coast is one of those neat little places in the country where you can find a bird usually associated with the most mild of climates in winter. Two species of hummingbirds are common in Oregon, and one, Anna's Hummingbird, remains on the coast during the colder, rainy months, sustained by feeders left out by people in addition to the plants that are still very much flowering.

Insect-eating songbirds are another case of birds who normally would migrate from the north during the colder months when their food sources dwindle, but are able to hang around on the coast. Black Phoebes, who have only recently expanded their range this far north, and Tropical Kingbirds, usually found in warmer climates are on the larger end of this group of birds, with the tiny Yellow-Rumped Warbler and both species of kinglet (Golden-Crowned and Ruby-Crowned) falling towards the opposite extreme. All feed on insects, whether by catching them mid-air or gleaning them from tree bark.

Other songbirds take advantage of the year-round availability of plant-based food, namely seeds. All manner of sparrows and finches, from the colorful Spotted Towhee to the marsh-dwelling Lincoln's Sparrow to the wacky-looking Red Crossbill, have adapted to exploit as many different types of seeds as can be eaten. Even birds that usually stick to fields find themselves taking advantage of the coast's abundance of food, like the below Lapland Longspur, a common songbird of the Arctic.

Then, of course, come the birds that you're probably used to, even if you don't always notice them. American Robins, Black-Capped Chickadees, Red-Breasted Nuthatches, Hermit Thrushes, and American Crows have found their place here as well, adapting to a life by the seaside.

eBird tells me that I saw 101 species of birds during my three and a half months on the Oregon Coast, and I barely even scratched the surface. 27 of those birds were completely new birds for me, bringing my life bird total up to 413. I aim to return to Oregon some day, so don't expect that 101 to be set in stone!
