More details on the upcoming Forest Grove CBC

Hooded OrioleHooded Oriole, Gaston, Oregon, 26 December 2009 by Greg Gillson.

 

Many birders got to see this wonderful rare bird at a private feeder, in the tiny burg of Gaston, soon after it was found on the Forest Grove Christmas Bird Count (CBC). My feeling is that there should be time available for each group to go "poach" a rare bird or productive area for an hour or so, outside of their assigned sector (count area). See the previous post (Forest Grove CBC: Join us December 17).

Each sector has certain "target" species that they should try to find, as they may only be found in that sector. Some sectors are mostly driving, some mostly walking. As of this time, all sectors are available and open to request. We need sector leaders, responsible to read the map, track the mileage and time, count all birds seen or heard, and take less experienced ones along for a fun day.

All volunteers should contact me, Greg Gillson, at greg@thebirdguide.com, and let me know what sector you prefer. Please consider being a sector leader.

If you live in the count circle (Roy to Gaston, Forest Grove to west part of Hillsboro) we need feeder watchers. Just keep track of all birds coming to your feeder and keep track of the time you spent watching. Most Anna's Hummingbirds are reported from feeders. If a Hooded Oriole comes to visit, well, one can dream!

Forest Grove CBC: Join us December 17



From December 14 to January 5, birders at thousands of locations across the Americas will count early winter birds in prescribed areas from dawn to dusk. For over 100 years the National Audubon Society has sponsored these Christmas Bird Counts (CBC). Read the History of the Christmas Bird Count on the Audubon site.

In Forest Grove, Oregon, volunteers will meet at 7:00 AM on Saturday, December 17, 2011, at Elmer's Pancake House at 390 SW Adams (near the corner of First Street and Baseline Avenue) in Hillsboro, Oregon. There birders will be divided up into car groups and sent birding in one of 8 sectors of the count circle. Everyone should meet back at Elmer's about 5:00 PM where you turn in your count forms and count fees are collected (yes, $5 per person is collected to help defray publishing the data in a special issue of American Birds). You may stay for a count-down dinner (each person buys their own), where the species seen are informally tallied.

I started helping organize the Forest Grove CBC two years ago. I was guided by two thoughts. First, I was vacationing in Arizona one winter and decided to attend a count near Phoenix that regularly tallies nearly 200 species--many species I highly desired to see. However, I was assigned to a group in a rural area of cotton fields with very few birds. When we finished covering our area by noon? Our leader had us do it again, with very few additional birds. All the while, I could see the greenery along the nearby river with all the birds I so desired to see but which was "not our area." Second, I knew the Forest Grove area so well. At the countdown dinner I realized that the birds that were missed that day were not hard to find--in fact, I knew exactly what tree and bush or part of the stream these missing birds hung out in. I figured if each team concentrated on finding these hard-to-find, but usually present, birds, then the common birds would take care of themselves. Counts since implementing this idea 2 years ago have exceeded the high count of all previous years.

This led me to redesign the count in such a way that teams could cover their area fairly well by noon, and "poach" in other team's areas for good birds--just keep track of where you were. I recommend teams "poach" at Fernhill Wetlands or Jackson Bottom Wetlands during the day. There is a good turnover of waterfowl at these locations, and many other sparrows and smaller birds hiding in the marsh. I also divided up Hagg Lake into three sectors rather than one. The special resident birds here are hard to find and quiet, and found no where else in the count circle. To help in this regard, I created sector material for the sector leaders specifying each sector's target birds and where to find them.

This year Christmas Day falls on a weekend and, unlike the very first CBC, few counts these days are actually scheduled for Christmas Day. That means most counts will be either December 17 and 18th or December 31 and January 1. Forest Grove isn't one of the "glamor" counts in Oregon. So we'll have lots of competition for our volunteer counters.

My next post will tell you why you should join us and what you might see.

Western Bluebird

Western BluebirdWestern Bluebird, Champoeg State Park, Oregon, 8 November 2011 by Greg Gillson.

 

I stopped by Champoeg State Park recently, and was able to photograph this Western Bluebird using my car as a blind.

This bird is banded, probably in concert with the Prescott Bluebird Recovery Project, which builds bluebird nest boxes and monitors populations locally in the northern Willamette Valley.

Champoeg was a town between Portland and Salem, Oregon. In the early 1840's the rapidly increasing number of settlers met at Champoeg and voted to set up a local provisional government. Up until that time both the United States and Great Britain jointly occupied the Oregon Territory, with the British Hudson Bay Company having a presence at Fort Vancouver (near present day Vancouver, Washington). Relations were friendly-enough between American and British subjects (and French-Canadian, Spanish, and Russian fur trappers), but there was really no "government" to speak of for the American settlers. This provisional government ruled until 1848 when Oregon became an official territory of the United States. Oregon became a state in 1859. In December 1861 a huge flood swept away the town of Champoeg and it was never rebuilt.

Learning about birds... at your feeder

Spotted TowheeMale Spotted Towhee, Beaverton, Oregon, 27 November 2011 by Greg Gillson.

 

For improving one's birding skills, Kenn Kaufman (Kaufman Field Guide to Advanced Birding) recommends a bird feeder as a learning tool. Even a common species observed closely over time can teach about age and gender differences, molt and plumages, hybridization, and individual or population variation. Learning how to observe these items on common birds will let us more quickly and accurately identify rare birds--a source of joy and excitement for many birders.

Earlier this year I learned something very interesting by observing the birds at my feeder. Although perhaps not surprising, I observed a subspecies of Spotted Towhee not previously documented in western Oregon. I wrote about it here: (Barely spotted towhee gets super spotted visitor).

Now that I am attune to this particular ID challenge, I was ready today when I again spotted an unusual towhee visitor to my feeder. The top photo shows a resident male Spotted Towhee, typical of those found in western Washington and Oregon, the so called Oregon Towhee (Pipilo maculatus oreganus).

The ID of the above bird is straightforward. Compared to all other populations it has fewer spots on its scapulars and wings. The rufous sides are darker than other populations. Finally, the spots on the undertail are very small, perhaps restricted to only the outermost tail feathers of each side of the tail.

Compare the bird above with the bird below, seen about 15 minutes apart in the same tree--photographed through my very dirty window!

 
Spotted TowheeMale Spotted Towhee, Beaverton, Oregon, 27 November 2011 by Greg Gillson.

 

This bird is paler orange on the side and undertail coverts. It has more and larger spots on the scapulars and wings. Obviously, the white tail spots take up more than half the tail and are spread out on at least three of the outer tail feathers.

This bird matches one of the "Interior" forms of Spotted Towhee. The new National Geographic Field Guide to the Birds of North America, Sixth Edition has range maps showing the various subspecies of Spotted Towhees.

Without a specimen to measure fine variations, it is only speculation as to which exact subspecies may be represented. And due to individual variation, even a specimen may not be unequivocally decisive in this matter. However, it is sufficient to separate the Pacific form (to which the Oregon Towhee belongs) from the Interior form to report this to eBird. In fact, birders in Washington are noting the winter influx of the Interior form of Spotted Towhees into western Washington where, as in western Oregon, they were previously undocumented.

These new winter distribution records are found, not from scientists studying specimens or conducting field research, but by amateur bird watchers at their backyard feeders!

What's in your feeder?

Brambling chase

BramblingBrambling, Scappoose, Oregon, 26 November 2011 by Greg Gillson.

 

It's been several years since I "chased" a rare bird outside of my home county. ('Chase' means to drop everything and try to go see a rare bird found by someone else, often far away.) Last year I worked on a County Big Year, setting a new record by seeing 199 species in tiny Washington County, Oregon. So I went looking for every unusual bird seen locally last year. This year I did more "relaxed" birding, with no numerical goals.

It took me a while to remember the last bird I chased outside of my local county. It was a Northern Wheatear on the coast in September 2009. I did get several good photos of this rare Eurasian (even rarely Alaskan-nesting) thrush-like bird.

When I heard of the Brambling (boldly-colored Eurasian finch) Friday afternoon in Scappoose, I was under the influence of cold medication and didn't really care. By evening I had convinced myself I felt better and would leave at dawn and join the chase! It was only 20 miles away, after all, and it was supposed to be sunny! There are only 11 previous Oregon records of Brambling. All prior records were birds that were found at residential feeders and most remained several days or longer. This one was in a wetlands with flocks of other sparrows, so would likely be more of a challenge to refind...

It was just starting to get light when I pulled into the parking lot at 7:20 AM. But it was a gloomy, cloudy day, not sunny as forecasted. For such a rare state bird I was surprised no one else was there yet. Where was Russ Namitz, who is working on a state Big Year this year?

I walked down the path toward the green shed where the bird was seen yesterday afternoon. There were 3 birders gathered near the shed. They had walked in from the other side. The three birders soon built to five. No joy. No bird. We were prepared for a long wait.

Photo above by Marlene Gillson just after we'd seen the bird!


At 8:10 AM, after we'd been waiting there by the shed about 30 minutes without success, a birder approached. It was Lona Pierce, who had discovered the bird yesterday. She didn't make it to us when she stopped and pointed and said, "There it is!"

True enough, we all got brief looks as it appeared in a hawthorn tree above the blackberries. I snapped off some quick photos, but none were very good. It was so dark that I tried flash, but that always makes birds look so horrible. Then it was gone.

Over the next hour and more, additional birders came. Some names I remembered, some I did not. Sadly, I am better at identifying birds than bird watchers. I think the following birders were present: John Gatchet, Bob Stites, Scott Carpenter, Don Wardwell, Henry Horvat, and Lona Pierce were the others I believe saw the bird. Birders that showed up later were Jay Withgott, Shawneen Finnegan, Dave Irons, Liz Gordon (wife of American Birding Association president, Jeff Gordon), Diana Byrne, Jim Danzenbaker, and several others. By the time I left, about 9:30 AM, the bird hadn't returned.

My other photos of the Brambling are linked here.
