While doing a point count at the Oak Island unit on Sauvie Island (Birding Oregon p. 56), I heard something large rustling in the brush and saw this beasty.

She blended in with her surroundings very well, but those big yellow eyes stand out.


I have seen Great Horned Owls hunting on foot before, but after watching this bird for a while I guessed that she was injured. I considered trying to take her in for medical attention, but the idea of capturing a large predator bare-handed is seldom a good one. She watched me watching her for several minutes before trotting nimbly down a little path through the brush.


Photographing a bird within brushy cover is challenging with my little auto-focus camera. The camera wants to focus on the closest objects, the leaves and sticks, leaving the bird blurry in the background. I had to find a tree trunk that was about the same distance away as the owl, focus on that, and then aim at the owl. This works well with a big stationary target like a Great Horned Owl, but is more challenging with warblers.

A flock of Bushtits were working their way through the garden the other morning. A foggy morning viewed through a dirty window doesn’t bode well for photography, but here are a few images that survived the slow shutter speed.

I took a brief walk around Fernhill Wetlands (Birding Oregon p. 61) while meeting with a reporter today. The weather was rather dreary, but, as always, there were some birds around.

eared grebe
Eared Grebe is an unusual visitor to the main lake. Note the thin bill and dusky cheeks. The more common Horned Grebe has a thicker bill, white cheeks, and a neat black cap.

Another view of the Eared Grebe. The back end of this species tends to float fairly high in the water.

cackling geese
Most of the wintering Cackling Geese were off grazing somewhere, but these two were hanging out on the lake. The bird on the right has pale feather edges, indicating a young bird.

canada geese
In contrast to the Cackling Geese, these resident Canada Geese are much larger with long snakey necks.

common mergansers
Common Mergansers were indeed common on the main lake this morning, but did not allow a close approach.

Great Egrets stand out on a dreary gray day.

Northern Flickers

northern flicker male front
Northern Flickers have been visiting the bird feeder lately. Their bills are not designed to crack open seeds, so they just pull all the seeds out of the feeder until they find one that is already open.

northern flicker female
Females lack the red mustaches found on the males.

northern flicker male
Since they are a common backyard species, we tend to take Northern Flickers for granted, or focus on their destructive habit of drilling into house siding. But on close inspection, we see that these are truly stunning birds.

This Black-capped Chickadee, a more common species at bird feeders, is dwarfed by the monstrous flicker. Northern Flickers normally eat ants and other insects, but will come to feeders offering suet or sunflower seeds.

Rockpipers

Two of the more common rock-loving shorebirds along the coast are Black Oystercatcher and Black Turnstone. Both species hang out on rocky shorelines in the intertidal zone, probing the wave-splashed rocks for mollusks.

black oystercatcher
Black Oystercatchers would be very hard to see against the dark rocks if it weren’t for their bright red bills.

black turnstones
Black Turnstones nest in Alaska, but spend the winter along the west coast from Canada to Baja California. Their backs blend in with the rocks, but their underparts are bright white.

limpets
Limpets are among these birds’ prey species.  The shorebirds use their stout bills to pry the animals off the rocks to reveal the soft underparts.

Review: Birds of Western North America

October 14, 2009 at 1:26 pm | In resources | 1 Comment

I came across a beautiful new field guide recently, Birds of Western North America: A Photographic Guide by Paul Sterry and Brian Small.
cover
I usually prefer field guides that feature paintings, rather than photos, since an artist can bring out key field marks and is not limited by the lighting or behavior captured in a single photograph. But the photos in this guide are a joy to look at, whether you are trying to identify a bird or are just flipping through the book.

bluebird spread
The layout of the book makes it very easy to use. Similar species are grouped together, and the text and range maps are directly across from the photos.  I really like how the bird images spill out over the frame, making the birds look large and three-dimensional.

hummer spread
In the hummingbird section, several species are shown in positions that do not exhibit their bright colors. Since these colors are only visible at certain angles, these photos will be helpful to beginning birders who are confused when they see a hummingbird with a “black” head.

The text is concise but highlights all the key field marks and behaviors. You can’t read the text on the above screen captures, but you can see examples on the Princeton University Press website. A companion volume covers the species of eastern North America.

Seen it all

October 9, 2009 at 10:41 am | In birding philosophy | 1 Comment

A birder recently told me that he didn’t do much local birding because he had “seen it all.” I understand what he meant; once you have birded an area long enough, it becomes increasingly unlikely that you are going to see any new species. But I will never reach the point where I have seen everything there is to see, no matter how small an area we are talking about.

feeder

As I am currently being held captive by our new puppy, I haven’t been able to get out into the field to bird for about two weeks. The bird feeder has been busy, but with the same half-dozen species that I normally see. Yet I continue to look out the window at every opportunity, just to see what is going on. Why? Because you never know. If a Brambling or a Xantus’s Hummingbird or a Rustic Bunting shows up around here, it will probably be at a backyard bird feeder. Even if the mega-rarity never shows, there is still plenty to see and much to learn about the more mundane. When will the Pine Siskins arrive this year, or will they? Will there ever be a Common Redpoll among them? Just the other day, a Pileated Woodpecker flew over the property. This is a new bird for the yard list. I happened to see this bird when I was taking the puppy out for the gazillionth time and noticed a shadow pass over us. I turned to glimpse this large woodpecker flying over and then disappear. What other species have flown over when I didn’t happen to glance up? In the eight years I have lived here, there have been noticeable changes in the bird species that use the property. The Northern Saw-whet Owl was a one-day wonder eight years ago. Completely absent a few years ago, both Lesser Goldfinches and Western Screech Owls are now regular visitors. Population dynamics will continue to change. New species will continue to appear from time to time. There will always be something new to see or learn, even in my little yard, let alone the county or the state. Seen it all? Not in my lifetime.

Fernhill Wetlands

While certainly not one of the more scenic sites in Oregon, Fernhill Wetlands (Birding Oregon p. 61) always attracts some noteworthy birds.

least and western sandpipers
Least Sandpiper (left) and Western Sandpiper (right) are two of the more common shorebirds that use the mudflats at Fernhill. Both birds are juveniles (brightly colored fresh plumage, scapulars are small and rounded). The Least has a small, finely-pointed bill, yellowish legs, breast streaks, and feeds while squatting low to the mud. The Western has a longer drooping bill, dark legs (hidden in the mud),  is grayer overall, and looks “front heavy,” like he might tip forward.

pelican swimming
Two American White Pelicans have been at Fernhill lately. This species doesn’t nest in the Willamette Valley, but small flocks are often present in late summer/early autumn.

winchuck river
Less than a mile from the California border, the Winchuck River empties into the Pacific Ocean. Along with a lovely beach area, the site has a nice visitor center (bathroom!) with information about the surrounding National Forest.

brown pelicans
Brown Pelicans were feeding just offshore.

long-billed curlew
Two Long-billed Curlews were feeding near the river mouth, probing their long bills into the sand. The crisp pattern on the wing coverts (dark stripes with no cross bars) identifies this individual as a juvenile.

double-crested cormorant
This Double-crested Cormorant  fished  in the river while other fished offshore.

eurasian collared dove
Eurasian Collared-Doves can be expected just about anywhere in Oregon after a massive range expansion over the past few years.

western fence lizard 1
Western Fence Lizards were basking on the abundant driftwood. This one has recently shed, evidenced by the little patch of dead skin left on the tail. The one below has a less dramatic pattern, but with little blue flecks.
