Gull Season

Late autumn and early winter is the time to find the biggest diversity of gulls in Oregon. I led a field trip to the coast at the end of October. Strong storms from the west had moved a lot of birds close to shore earlier in the week, but on the day we arrived, strong east winds had driven a lot of birds back out to sea. At least we didn’t get rained on.

At the Seaside Cove, a few gulls posed for us in the sun. This gull is mostly Western, but the streaking on the head and neck suggest some Glaucous-winged ancestry.

This is a fairly robust Iceland Gull (Thayer’s subspecies).

A closer look at the Iceland. The yellow bill will fade as the season progresses.

There aren’t a lot of places in the Portland area to get close looks at gulls anymore. This group was hanging out on a bar in the Willamette River. The flock was a mix of California, Ring-billed, Herring, Iceland, Glaucous-winged, Western, and a mass of messy hybrids.

While scanning the genetic soup of confusing hybrids, it was refreshing to land on a Ring-billed Gull.

While this bird ticks most of the boxes for Herring Gull, the bill seemed a little too heavy to me. This, combined with the primaries which were slightly less than jet black, suggest this might be a Cook Inlet Gull (Herring X Glaucous-winged).

This Glaucous-winged Gull was hanging out in a flock of Cackling Geese at Amberglen Park. I am guessing that the grazing geese were stirring up worms for the gull.

Happy Gulling!

Wet (land) Birds

Here are some non-waterfowl that I’ve seen in various wetlands recently.

I often struggle with photographing white birds, but this Great Egret came out OK.

Most of the shorebirds have moved on, but a few Least Sandpipers are still around.

The winter sparrow flocks are building up. This Golden-crowned Sparrow was still sporting their breeding plumage.

The numbers of Nutria in the Willamette Valley have exploded in recent years. The are indeed non-native and invasive, but the babies are so cute.

Waterfowl

OLYMPUS DIGITAL CAMERA

Waterfowl numbers have been increasing in the Willamette Valley as the rains have begun. This male Northern Shoveler is still in his drab summer plumage.

OLYMPUS DIGITAL CAMERA

This Emperor Goose is currently a local celebrity in the Beaverton area, hanging out with the local ducks and Cackling Geese.

OLYMPUS DIGITAL CAMERA

This Gadwall was hanging out at Koll Center Wetlands. A brick building at the edge of the pond creates those brown reflections in the water, which complement the colors on this duck.

Numbers of ducks and geese should continue to increase into November.

How to Watch an Owl

great horned owl 2

A lot of people, both birders and non-birders, are fascinated by owls. I personally don’t get more excited by owls than any other group of birds, but some folks just lose all ethics and common sense when they come within close proximity of an owl. As I have often said, owls make people stupid.

Much of the worst birder behavior I have witnessed has been around owls. When people get too close, the results can range from simply annoying the animal to putting the bird at serious risk. So, I would like to offer a guide to enjoying these birds is such a way that keeps everyone involved safe from stress and harm.

Ethical owling is achieved by starting with two clear premises:

  1. Owls don’t like you.

To most species of wildlife, humans are perceived as a clear and present danger. Despite being predators themselves, owls are preyed upon by other species. The best defense employed by many owls is camouflage and just staying hidden during the day. If a large predator, like you, approaches an owl, the bird may become stressed, even to the point of flushing from their hidden perch. This in turn puts the owl at increased risk of being attacked by another predator.

  1. If an owl is looking right at you, you are changing that bird’s behavior, which may be putting the bird at risk.

That owl could have been sleeping, watching for potential prey, or preening. Your presence is preventing all of those natural behaviors. By observing and interpreting an owl’s behavior, you can effectively judge your potential impact on the bird and adjust your actions accordingly.

Smaller species of owls rely on their camouflage to keep them safe, and may remain completely still if you approach. So just because the bird is not flying away, it doesn’t mean that you are not causing stress. With larger species, you may be interfering with hunting activities or alerting other animals to the owl’s location.

If an owl is paying any attention to you, you are too close. When you encounter an owl, even if the bird does not seem affected by you, enjoy them briefly from a respectful distance and then move on.

A longer version of this post, complete with photos of various owl behaviors, is available on my Patreon Account.

Random Non-birds

Here are a few images of various animals I have seen lately. When the birds refuse to pose for photos, it is nice to find other creatures that are more cooperative. As I have said, there is always something to see.

brush rabbit smallBrush Rabbit, Fernhill Wetlands

bullfrog smallBullfrog female smallThe top image shows a massive male American Bullfrog found at Dober Reservoir. Note the injury around his right eye. The bottom image is of a newly emerged female. At this stage, she was about the size of the males head, but females typically grow larger than males of this species.

butterfly smallOrange Sulphur, found at Jackson Bottom. Unfortunately, this species perches with their wings closed, so you can’t see the vibrant colors on the top.

Mylitta Crescent smallThis Mylitta Crescent at Fernhill Wetlands was much more cooperative.

striped meadowhawk smallI don’t know the dragonflies, but I am told this individual from Fernhill Wetlands is a Striped Meadowhawk.

ground squirrel smallCalifornia Ground Squirrels, one of my favorite rodents, have become more common at Fernhill Wetlands since the reconstruction a few years ago.

September Shorebirds

Greater Yellowlegs

Shorebirds have been trickling through the Portland area all month. Finding proper habitat can be challenging. As wetlands dry up during the summer, we have to hope that deeper bodies of water recede enough to create mudflats for shorebirds to feed on. This Greater Yellowlegs was at Force Lake in north Portland.

g yellowlegs trioTypically seen wading, Greater Yellowlegs will occasionally swim in groups to catch small fish.

Low Tide

trestle bay 2Trestle Bay, just off Parking Lot D at Fort Stevens State Park, can be one of the more productive shorebird spots on the north coast. Timing is critical, as the bay fills completely with the high tide.

trestle bay 1When the tide is out, the bay provides extensive mudflats. With this much exposed mud, the birds can be quite distant, so timing your visit when the tide is coming in can produce some nice viewing.

sea lion 1On this visit we observed what we thought was a California Sea Lion carcass way out on the flat.

sea lionLater we noticed the the sea lion had rolled over and extended a flipper. Apparently he was just hanging out on the mudflat catching some sun.

sea lion stretchI normally see these animals basking on rocks, but the mud was apparently working for this guy.

mergansersSouthbound shorebird migration tends to come in waves, and we were between waves on this visit. Our consolation birds were this flock of Common Mergansers with a California Gull.

Happy last days of summer.

Summer in the Wetlands

Our brutal summer continues. When the weather is this hot and dry, the best bird diversity is usually found around wetlands, so I spent a little time at Fernhill Wetlands and Jackson Bottom.

b phoebe smallThe first record of Black Phoebe in Washington County was in 2006 (by yours truly). Now they are rare but regular at both Jackson Bottom and Fernhill.

least sandpiperShorebird migration is in full swing. Numbers are better at the coast, but some birds are finding the small patches of mud at inland locations. This Least Sandpiper was feeding on some newly exposed mud at Jackson Bottom.

Wasco County

river smallHere are a few more images from my trip to central Oregon. The main purpose of the trip was to get the dogs away from the fireworks in Portland, but I always enjoy a trip to the dry side of the Cascades. It was indeed dry, and very hot. Bodhi cooled off a little in the Deschutes River.

tv flockI found a small flock of Turkey Vultures roosting along the river one morning.

tv left smallEven in the early morning the sun was pretty intense.

spotted sandpiperThis young Spotted Sandpiper was perched on a rock in the river.

mule deerThe Mule Deer were usually found along the river, which provided the only green vegetation in the area.

fence instaSince birding was pretty slow, I spent a lot of time with Western Fence Lizards. This individual was basking on a big piece of obsidian. Since it was so hot, these lizards usually basked in the shade except during the early morning.

fence lizard smallThis individual was hanging out under the deck where we were staying. I had to use a flash in this dark environment. I normally don’t like the results of flash photography, but the flash really brought out the pattern on this lizard.
