Birding Oregon with GGBA

Birding Oregon with GGBA

By John Tysell
I met our guide, Harry Fuller, in Ashland, Oregon where he lives. I had done a previous Golden Gate Bird Alliance trip with him in 2013 in the Cascade and Siskiyou Mountains of southern Oregon. It had been a great birding experience, so I was looking forward to spending the next three days with him on his June 2014 trip to Malheur National Wildlife Refuge. 
Susan and Maureen, also GGBA members, joined us early on Wednesday morning and our car caravan headed east down Dead Indian Road. Malheur — a high desert basin in southeastern Oregon with an average elevation of 4,000 feet — is a birding hotspot. The snowpack on the Steens Mountains delivers ample water for wetlands, streams, meadows and grasslands. The varied habitat provides shelter and abundant food, especially insects. Since it is a perfect setting for breeding, I was hoping to see young at this time of the year.
As we climbed up the foothills, the trees became fir and pine. We stopped for a Lazuli Bunting and a Mountain Bluebird along the way. Near Howard Prairie Lake, we saw Sandhill Cranes in a meadow with young. A must stop was Rocky Point on the Eastern shore of Upper Klamath Lake. The highlight was a pair of Red-breasted Sapsuckers flying in and out of their cavity nest feeding babies.

Close to Fort Klamath along the Sun River, we stopped to see Ospreys with fledglings in the nest. A Bald-headed Eagle soared in the distance. At Collin’s Rest Stop, I saw my first American Dipper, one of fourteen new species I would add to my life list. Then the highlight of the day: Red Crossbills.
After leaving the town of Silver Lake, we passed a large dark-brown bird on a post. The walkie-talkie crackled. Susan observed that it was too large to be a hawk, so the caravan turned around to find a Golden Eagle. Further East in Christmas Valley, we saw Ferruginous Hawks, a Long-billed Curlew and Wilson’s Phalarope.
Late in the afternoon, we finally arrived at the Malheur Field Station on Sodhouse Road near New Princeton, Oregon. It is isolated and filled with wildlife. Our dorm was old and worn but clean. Despite the drought, the faucet leaked freely. On our way to the cafeteria, Common Nighthawks were seen sitting on the railings.…

New clues to a Band-tailed Pigeon mystery

New clues to a Band-tailed Pigeon mystery

By Jack Dumbacher
In recent months, I’ve seen and heard many Band-tailed Pigeons around my house in Marin. Their burst of slapping wing beats can surprise me if I flush them from a low perch, or I might hear their resounding call drifting down from a perch high in the redwoods. I always appreciate hearing or seeing them, as their populations overall have been in decline for many years.
These pigeons have posed a conservation puzzle. Although their populations have been declining at a rate of about 2.8-3.0 percent range-wide for multiple decades, no one has known the reason why [1]. Just to put that into perspective, a 2.8 percent decline will reduce a population to under one quarter of its original size in 50 years time. And Band-tailed populations are already much lower than historical numbers, although no reliable data exists to say just how much.
In 1913, U.C. Berkeley’s own Joseph Grinnell wrote an article for The Cooper Ornithological Society’s journal, the Condor, about the bleak future of the Band-tailed Pigeon as a game bird in the western United States [2]. In fact, the Band-tailed Pigeon offers striking parallels with the Passenger Pigeon. They lay a single egg, they follow boom-and-bust cycles of acorns and other fruits, there are certain times of year – mostly winter – when they congregate in large numbers, and it is difficult to predict exactly where the larger winter flocks will reside.

In the winter of 1911-1912, the birds were so common in San Luis Obispo and Santa Barbara that hunters arrived by trainloads and hunted the birds, Passenger Pigeon style. The concern of W. Lee Chambers [3], Grinnell, and others led to a ban on hunting that lasted until the early 1930s.
As the numbers began to rebound, farmers complained of crop damage and continued to hunt them. Especially in winter, flocks would appear large and destructive in California, mostly because the bulk of the western races (Patagioenas fasciata monilis) would gather and overwinter here. However, there was little evidence that they actually damaged crops during these months [1]. Band-tailed Pigeons are still legal to hunt in California, but limits are low and this is not believed to have a negative impact on their population.
We now know why the Band-tailed Pigeon’s biology resembles the Passenger Pigeon’s: They turn out to be each other’s closest genetic relatives.…

Osprey starting to nest along the Bay

Osprey starting to nest along the Bay

Golden Gate Bird Alliance is part of the Bay Area Osprey Coalition, a new group working to protect and educate the public about the growing number of Ospreys nesting along San Francisco Bay. We co-sponsored the second annual SF Bay Osprey Festival in June at Mare Island (Vallejo), and are working to encourage bayside property owners to install nesting platforms. The San Jose Mercury/Contra Costa Times ran an excellent story this week on the spread of nesting Ospreys to the Bay. We’re reprinting some excerpts below (including a quote from GGBA Executive Director Cindy Margulis), but you can read the entire story on the San Jose Mercury web site.

RICHMOND — The osprey, a fierce and powerful fishing bird, used to be just another San Francisco Bay shoreline visitor, flying over and feeding without setting down roots.

These days, however, the acrobatic divers are becoming natives, constructing elaborate stick nests on cranes, poles or other man-made structures. Ospreys nested in 21 places around the bay shorelines this year and 17 last year, up sharply from a single active nest in the early 1990s. Most of the new nests are in the East and North Bay.

Before that, ospreys steered clear of the bay, preferring to nest in areas far north of the Bay Area, or inland, especially near lakes. Scientists aren’t sure why the raptors have made the move. They speculate it may have something to do with changes in bay water quality, clarity and abundance of fish. Or it may have something to do with bald eagles — another species on the upswing — crowding ospreys out of their prime nest spots near lakes in the North Bay. “We don’t have all the answers, but the nesting territory is a significant change that has occurred in a relatively short period of time,” said Tony Brake, a volunteer bird monitor with the Golden Gate Raptor Observatory.

Although osprey populations were once threatened because of DDT contamination, the birds now prosper in many areas, living on every continent except Antarctica. They migrate through or winter in the Bay Area, and they have nested in the past around Lexington Reservoir near Los Gatos and Kent Lake in western Marin County.…

Making it work on the South Coast

By Phila Rogers
I don’t think I could have written these words even two months ago because I was still unreconciled to my move to Santa Barbara. This is NOT my home, I would have told you. And then I would begin my rant. Where are the robins to sing up the dawn? Where are the chickadees chattering in the oaks, or the Great-horned Owls hooting at dusk from the eucalyptus?
Nothing was right. Here, it is a cacophony of crows – an unholy chorus – from dawn to dusk. The creek next to this retirement “campus” is dry as a bone, lacking the lush streamside vegetation to attract the spring singers like the Swainson’s Thrushes, Warbling Vireos, and Wilson’s Warblers that populated my beloved Strawberry Canyon.
Some days, I would imagine sitting on the bench under the sheltering branches of the oak I had planted 60 years ago. Or I would envision myself at the U.C. Botanical Garden, climbing the path up to the Old Roses garden, and to the fence line where I could look up the steep chaparral-covered slope to the bent tree at the top of the hill. Coming down, I would stop to view the Bay in the “V” of the hills. Of course, there would be robins singing everywhere, and the Olive-sided Flycatcher calling from its perch at the top of a redwood.
There’s no cure for this nostalgia other than to acknowledge that I will always look at what’s around me through Berkeley eyes. I don’t want to surrender that perspective. But maybe I could allow myself to consider the virtues of the South Coast, of Santa Barbara where everyone wants to come and visit and — if they could afford to – stay.
A month after I came to live here last September, flocks of Yellow-rumped Warblers arrived, just like the ones in Berkeley. The manicured gardens of lawns, palms, and agapanthus beds were just fine with them. They dove into the palms and out again, forever “chipping.” Then a Hermit Thrush took up winter residency beneath the live oaks below my bedroom window. And then a troupe of cheerful White-crowned Sparrows arrived, singing sweetly, but in a different dialect.

My retirement community is just up the hill from Oak Park, one of the scruffier city parks but with some fine live oaks and sycamores. Sycamores are new to me except for the ones I would infrequently see out around Sunol where they favored the flats near streams.…

A fallen sparrow spurs a bird-friendly schoolyard

A fallen sparrow spurs a bird-friendly schoolyard

By Anthony DeCicco 
Imagine you are a Golden-crowned Sparrow. You hatched in 2013 on the shrubby lowland tundra of Middleton Island, about 80 miles off the coast of Alaska. You were banded on September 15 of the same year, and eventually you make your natural journey southward along the Pacific Flyway.
You stop along forest edges, shrubs, chaparral, and backyards for about 2000 miles until you come to the garden at Verde Elementary School in North Richmond, California. Its lush habitat is alluring, and you stop to rest in a Coast live oak. The view south looks promising as you fly quickly from the oak’s branches – but what appeared to be a sunny horizon and more trees turn out to be reflections from a large classroom window. You collide. The impact is too much, and flapping wildly, you fall and pass away at the base of the oak.
The third graders in our Eco-Education program found “Goldie” and noticed the tiny metal “ring” on its leg on January 10, during their initial schoolyard habitat survey. We reported details of the band to the U.S. Geological Survey, which sent the students a certificate with details of the bird’s banding:

“This record is actually quite unique and documents one of the longest movements for Golden-crowned Sparrow in our database.”

It is estimated that a billion birds die annually in North America as a result of window collisions like Goldie’s.
The children were both fascinated and sad. They wanted to help prevent future window strikes but were at a loss for solutions.
Fortunately their interest coincided with a pilot program GGBA had been starting to develop in Richmond this year – creating “Bird-Friendly Schools.”
GGBA Eco-Education staff helped the children create a flock of beautiful bird silhouettes and place them on school windows.

Next school year, these students can serve as advocates for other steps that would help transform Verde Elementary into a Bird-Friendly School, such as:

  • Treatments on all key windows.
  • More native flora habitat.
  • Placement of monitored and appropriate feeders.
  • Installation of nest boxes for Western Bluebirds, Chestnut-backed Chickadees and (possibly) Barn Owls.
  • Advocating for a ban on pesticides and rodenticides and for adoption of a “lights out” policy on school grounds.

Elsewhere in Richmond, Eco-Education students at Lake Elementary were also busy taking bird-friendly action this year.…
