Surprises on the Albee-Ukiah Bluebird
Trail: Submitted by Jack Simons Sharon and I toured the trail on Sunday,
August 15 and were surprised to find that four nestboxes still had
chicks. Three of these boxes had 9 large chicks that were ready to
fledge while the fourth box, Number 11, had 4 very small chicks that
will need at least two more weeks of munching on insects before they can
"fly the coop". Nestbox 11 has been a good box this year: 5 fledglings
from the first hatch and I had hoped to give club members a final tally at this time but we’re on ‘bluebird time’ here so I can only give you a few numbers from the first hatch that compare 2009 to 2010. Surprisingly, first hatch numbers for both 2009 and 2010 were very similar. For instance, in both years every nestbox was occupied by Western Bluebirds (31/31 in 2009 and 32/32 in 2010) for a 100% occupancy rate. In 2009 there were 159 eggs laid compared to 154 in 2010; egg mortality in 2009 was 12% (19/159) while egg mortality in 2010 was only 6% (10/154). More first hatch chicks died in 2010 (25/139 or 18%) than in 2009 (18/129 or 14%). The number of chicks fledged from the first hatch was very similar for both years despite egg and chick mortality: 116 chicks fledged in 2009 and 109 chicks fledged in 2010 for a combined total of 225 fledged chicks for both years. Second hatch numbers were not complete so we’ll have to wait to see how the remaining 13 chicks fared. There is a large insect population at this time so that will be in their favor, but overnight temperatures at that elevation have likely been rather cool the past few weeks. I know that my weather station recorded a low temperature of 37 degrees this morning (Friday, August 20) which is probably the reason I have nothing but green tomatoes in my garden!!! However, I can share the second hatch nestbox occupancy figures with you. In 2009, 71% (22/31) of the second hatch nestboxes were occupied while only 22% (7/32) of the second hatch nestboxes were occupied during 2010. We should have all of the figures crunched by the time the September issue rolls around. Meanwhile, stay warm (or should I say ‘cool’?) What a weird stretch of weather we’ve had this year!

Lewis’s Woodpecker (Melanerpes lewis) Submitted by June Whitten To my eyes, the Lewis's Woodpecker is an absolutely gorgeous bird! The very dark green back and tail, appearing almost black, set off with a gray collar and a lovely crimson-red belly and face all add up to make a striking bird. This is a bird of the west, breeding in British Columbia and all of the western states south to Arizona and New Mexico. The favored habitat for this woodpecker is open Ponderosa Pine forest, riparian woodland, and logged or burned forest with standing snags. An important segment of this habitat includes a brushy under story offering ground cover, including dead or downed woody material and abundant insects. Snags are very important for nesting sites, which they excavate, and for perches from which they do a lot of sallying for insects, much like a flycatcher instead of a woodpecker. Lewis’s Woodpecker was, no doubt, well known
to many Native American Tribes throughout the western states. Its first
identification by non-native Americans came from those intrepid
explorers, After traveling for more than a year and a half, the expedition was in the vicinity of present-day Helena, Montana. Lewis wrote in his journal: "I saw a black woodpecker (or crow) today about the size of the lark woodpecker (yellow-shafted flicker) as black as a crow. I endevoured to get a shoot at it but could not. It is a distinct species of woodpecker; it has a long tail and flys a good deel like the jay bird." It really should not surprise us that he thought the woodpecker was black. Without binoculars and probably at some distance, the bird would, indeed, appear black. However, on the return trip a successful
"shoot" was made and Lewis again describes the woodpecker which would
later bear his name: "The black woodpecker which I have frequently
mentioned and which is found in most parts of the rocky Mountains as
well as the Western and S.W. mountains, I had never an opportunity of
examining until a few days since when we killed and preserved several of
them. This bird is about the size of the lark woodpecker or the turtle
dove, tho’ it’s wings are longer than either of those birds. The beak is
black, one inch long, reather wide at the base, somewhat curved and
sharply pointed, the chaps are of equal length. Around the base of the
beak including the eye and a small part of the throat is of a fine
crimson red." In spite of their daily responsibilities and
exhausting trek, both Lewis and Clark managed to keep accurate
Both male and female Lewis’s Woodpeckers excavate the nest cavity, usually in dead or decaying trees, often in burned trees, and line the nest with wood chips. Nests are often reused the next year. Usually 6 or 7 opaque white eggs are laid and incubated for 12 to 16 days. The female usually takes daytime duty and the male incubates at night. The young fledge between 28 to 34 days, but remain near the nest site for about 10 days begging the adults to bring them food, which consists mostly of insects. The adult call is a series of short, harsh "chr" notes. The drum is short, weak, and at a medium speed followed by several individual taps. The Lewis’s Woodpecker is of high conservation importance, because of its rather small and patchy distribution. The estimated decline of this species since l966 is as much as 50 percent. The final cause or causes of the decline is unknown, but lack of snags left standing in logged or burned areas appears to be a factor. The increase of European Starlings in their nesting area may be a big reason for their decline, as the starlings take over the already excavated nest sites. One of the best areas in Umatilla County to see Lewis’s Woodpeckers is the Tower Burn, which is reached by taking Soap Hill Road (which becomes USFS Road 52) south from Ukiah. After approximately 12 miles, take USFS Road 55 (aka Texas Bar Road) down through the burn area to the John Day River and out to Hwy 395, if desired. This road is not snow-plowed, so a good time to look for Lewis’s Woodpecker is after the snow has melted in May or early June. Check out blackened snags for their nests.

Bird Words Nidifugous \nye-DIFF-yuh-gus Meaning: leaving the nest soon after hatching
"Nidifugous" hatched from the Latin words "nidus," meaning "nest," and "fugere," meaning "to flee." Its contrasting word "nidicolous," meaning "reared for a time in a nest," combines "nidus" with the English combining form "-colous" ("living or growing in or on"). Another relevant term is "precocial." A precocial bird is capable of a high degree of independent activity as soon as it emerges from the egg. While all nidifugous birds are also necessarily precocial, some nidicolous birds are also precocial — that is, they are capable of leaving the nest soon after hatching, but instead they stick around. Other nidicolous birds are "altricial," which is to say they are hatched in a very immature and helpless condition and require care for some time. Source: Merriam Webster’s Word of the Day,
Merriam Webster Online….Unabridged Editor’s note: Dave Herr told me that California Quail are nidifugous birds and he was right. There was one day that I didn’t check the nest with the 13 eggs reported in the last newsletter (see photo, right) and the following day all I found were shells and the family had vacated. Last week there was a quail family with a bunch of teen-age quail, hopefully that was them! B. Clark
Birding the Pacific Northwest: Baker County, Oregon Submitted by Barbara Clark Baker County advertises that it is a fine place for watching birds, and that it is!! Like Umatilla County, birds hang around all year with a parade of different species as the seasons pass. During my two-week stay just out of Halfway at the end of July / beginning of August, I was delighted by Cedar Waxwings flying playfully after each other over the pond in front of the cabin, Rufous Hummingbirds menacing any Black-chinned Hummers that attempted to come to the feeder on the porch, and a young Red-tailed Hawk flying each day after its mother over the meadow continuously calling to her in the Red-tailed language, that piercing, descending Kee-eerrrrrr ! On my walks at the edge of the meadow along the creek and forest were Black-capped Chickadees, Lazuli Buntings, Gray Catbirds, Western Wood-Pewees, California Quail with young, Chipping Sparrows, Mourning Doves, Song Sparrows, a Red-Naped Sapsucker, and more! Baker County’s local birders recommend several special sites for good bird viewing:

July – August Bird Sightings Compiled by Aaron Skirvin This is the season when shorebird migration normally kicks into high gear. Although McKay Reservoir has dropped enough to attract some shorebirds, the water level in Cold Springs Reservoir, which is the premier shorebirding site, remains too high to provide the mudflats needed by migrating sandpipers and plovers. The nesting season for most bird species is winding down, and we received many reports of young birds this past month. If you’re looking to hone your sparrow ID skills, now is a good time to drive Mud Springs Canyon Road or Gurdane Road, where you can see dozens if not hundreds of sparrows of several species. And, to make the experience even more challenging you will find adult and juvenile birds in the mix. Want to find a Mountain Quail in Umatilla County? August is the best time to look for these elusive and rare birds along the North Fork John Day River in extreme southern Umatilla County. On the evening of July 18, Craig Kvern saw 3
adult Gray Partridges with about 18 chicks along Adams Road near
its intersection with Thornhollow Road. The next day, I I spotted a flock of 14 American White Pelicans flying over Mission Ponds on July 19. A few evenings prior, Jack Simons reported counting over 78 American White Pelicans in 3 groups flying westerly over his house, which is only a quarter mile from Mission Ponds. While walking his dogs on July 20, Jack Simons
found 4 fledgling Western Wood-Pewees along the Umatilla River
near his home. Jack also noted a pair of vocalizing Eastern Kingbirds
but hadn’t seen any young kingbirds. The day before, a Cedar
Jack saw more fledged flycatchers in his neighborhood on July 23: a family of 5 Western Kingbirds and a family of 6 Eastern Kingbirds. On the 25th, Jack reported seeing more young birds near his home, including a family of Western Wood-Pewees and a family of House Wrens. Marveling at the number of baby birds he’d seen around his home, Jack commented, "I don’t think I have ever seen as many young birds that have hatched in the river bottom as this year." Joy and Steve Jaeger installed nine bird nest boxes on their property on Cabbage Hill. While checking the boxes on July 23, the Jaegers found nestling Tree and Violet-green Swallows nearly ready to fledge and a new Western Bluebird nest in their boxes. Joy further reported that on July 28 all of the boxes had evidence of nesting birds, including a couple of boxes that House Wrens had filled with twigs. Neal Hinds had a good morning of birding at
Cold Springs NWR on July 24, when he found 30 species of birds. His
highlight of the morning was spotting a group of three Great Egrets
perched in a snag at Memorial Marsh. It turns out that July is the month
that we are least likely to see Great Egret in Umatilla County. Even
during winter, two or three Great Egrets can be found in the Stanfield
area, where at least one can often be seen wading in Stage Gulch Creek
in the middle of town. It was only recently that Great Egret was first
reported here in July, when Neal found one at Cold Springs NWR on Driving by Pendleton Community Park on July 25, I noticed several gulls on the lawn in the park, and one of the gulls looked larger than the others. I stopped to take a closer look and confirmed an adult California Gull in the group of Ring-billed Gulls. While Ring-billed Gulls are common in town, it’s noteworthy to find a California Gull in Pendleton. By July 28, Jack Simons was beginning to have second thoughts about extending the "welcome mat" to the remarkable number of kingbirds around his home. Jack reported, "I walked out onto our deck and happened to look over at the raspberry bushes where I saw an Eastern Kingbird sitting on a high branch. I figured it was just waiting for a bug to wander by and ‘sure enough’ it dove into the raspberries and came out a few seconds later where it sat on the same branch. What was in its mouth? A juicy red raspberry which it managed to swallow! I didn’t know kingbirds ate berries but they apparently do." By the end of July, two Osprey juveniles fledged from the power-pole nest at the east end of Pendleton. This is the notorious nest that the Ospreys rebuilt with innovative and recycled building materials this spring (see the April 2010 newsletter in the newsletter archives library on the club’s website at www.pendletonbirders.org).The rarest bird reported this month and the
entire year, so far, was a WHITE-WINGED DOVE observed by Neal
Hinds at Cold Springs NWR on July 31. Neal
Joy Jaeger reported that Townsend’s Solitaires had at least one successful nesting in the vicinity of their mountain property, which is located a few miles from Albee. Over the weekend of July 31/August 1, Joy saw and photographed two "polka-dotted," juvenile Townsend’s Solitaires as they foraged around the Jaeger’s cabin. Every year, a few Black-chinned Hummingbirds spend the summer in Jack Simon’s neighborhood and visit the feeders in his yard. This year is no exception, and he has several Black-chins around his yard. However, on August 3, Jack noticed a different hummingbird at his feeders. Initially, he thought it might be a female Anna’s, but upon further observation he decided it was a female Rufous Hummingbird. Two days later, the female Rufous Hummingbird was still at Jack’s feeders, trying to assert its dominance over the Black-chinned Hummingbirds. It harassed the other hummers and chased "a bedraggled female B.-chinned into the ground where she took refuge in a foundation vent" of Jack’s house. Continuing to keep track of the shorebirds at
Cold Springs NWR, Neal Hinds added Solitary Sandpiper to the
Umatilla County year bird list when he photographed two at The bird-interaction dramas continued in Jack Simons’ yard through early August. This time, Jack saw at least 10 American Robins, mostly immature birds, fighting over the bird bath. Thus, we can conclude that not only did the flycatchers have a good nesting season, so did the robins in Jack’s neighborhood. On August 9, Jack noted that at least 8 hummingbirds were using his feeder, but he had no further reports of egregious assaults. Also on August 9, June and Duane Whitten had a male Rufous Hummingbird join the summer-resident Black-chinned Hummingbirds at the feeders in their SW Pendleton yard. Apparently, some Red-breasted Nuthatches were dispersing/migrating by August 10, as I had one in my yard in SE Pendleton, which is poor habitat for nuthatches. About 6:30 on the evening of August 12, Connie Betts noticed three Common Nighthawks flying/foraging over her neighborhood in SW Pendleton, but by 7:30 pm, the number increased to at least 10 nighthawks. Lynn Tompkins and her interns at the Blue Mountain Wildlife Center reported finding an adult Bald Eagle, an Osprey, and seven Turkey Vultures at Langdon Lake on August 13. A report of a Bald Eagle during the summer months in Umatilla County is a rare event, but in the past two or three years a few have been reported. With the remarkable increase in Bald Eagle numbers in the Pacific Northwest and nationwide over the past decade, we’re hopeful that in the near future the Bald Eagle will once again be listed as a breeding species in Umatilla County. In our area, the fall shorebird migration extends from late June through October and into early November. Cold Springs Reservoir and McKay Reservoir are the best shorebirding spots. Because of the wet spring weather that lasted well into June this year, McKay Reservoir and Cold Springs Reservoir were still too full of water in July to provide shorebird habitat (mudflats). By mid-August, the water level in McKay Reservoir had dropped enough to expose some mud at the upper (south) end. Neal Hinds reports that Cold Springs Reservoir is even further behind schedule this year and won’t begin to show mudflats until late August. Taking advantage of the lowering water levels in McKay Reservoir, June Whitten and I birded the upper end of McKay Reservoir on the morning of August 15. We found a few dozen shorebirds, with most of them foraging within 25 to 100 feet from us. In all, there were 11 species: Western (30), Least (4 or 5), Semipalmated (at least 4), Baird's (3), Solitary (1), and Spotted Sandpipers (2); both Yellowlegs (1 each); Long-billed Dowitcher (3); Semipalmated Plover (1); and Killdeer (10 or so). We also had good views of a juvenile and an adult Forster's Tern and one adult Common Tern. After birding at McKay Reservoir on the 15th,
June and I headed to Pilot Rock, Vinson and Gurdane. In mid- to late
August, the grassland habitat along the Gurdane Road can
On August 16, Jack Simons spotted a Barn Owl hiding in a brushy thicket along the Umatilla River near his home. This is the first Barn Owl he has seen in his area in several years. When I stepped out the door to head for work about 7 a.m. on August 18, I heard an Evening Grosbeak calling from some tall trees about a block away. This is the first time I’ve observed an Evening Grosbeak in Pendleton in the summer. We are more likely to find a few migrating grosbeaks in town in April/May and again in October, but in recent years the grosbeaks have been less reliable in the spring. Fall migration is underway and that means many species will be leaving (Long-billed Curlews and most Cliff Swallows have already vacated Umatilla County); some will be arriving for the fall/winter (look for the first White-crowned Sparrows about September 1); and some will be passing through (warblers and shorebirds). Fall migration is a great time to look for birds, so spend some time birding and send all your sightings to Dave Herr at dsherr@mac.com or 541-276-6413.
