Nathan's article has a part 1, where he has recordings of the calls of Winter and Pacific Wren, and says that while at first glance the spectrogram of both recordings looks the same, the loudest part of the Pacific Wren spectrogram (where the vertical black line is thickest) is in the 6 to 7 kHz range, while the spectrogram for the call of the Winter Wren is thicker at half that frequency (meaning that the bird is louder in that lower frequency range). The spectrogram of the recordings that I obtained yesterday appear to me to match Nathan's spectrogram of Pacific Wren: http://earbirding.com/blog/archives/774 vs https://ebird.org/checklist/S129533131 Thomas Geza Miko Claremont, LA County 909.241.3300 "With a sufficiently large sample size a correlation can at once be both very significant and too small worth discussing."--Daniel Kahneman toggle quoted message Show quoted text |
Hi Folks, Yesterday when I was listening to my recordings I was pleasantly surprised that I got a recording of the "Winzer Wren" singing. Well apparently what may have happened (strong possibility) is that I accidentally turned on my phone while live recording the bird and picked up the recording off the app of a Winter Wren singing, instead of the actual bird singing. The bird did sing while I was there but I may have accidentally recorded my own phone (until Amazon finally delivers the flux capacitors for my DeLorean I'm never going to find out). The other two recordings of the bird calling are definitely live recordings of only the bird and nothing coming off my phone. I checked on this topic last night with a couple of people who put the work into helping me figure this out. Worst comes to worst I may go back tomorrow or Monday and try to get more recordings of the bird with my shotgun microphone and make sure that the same mistake doesn't happen again. I've never actually done this before. I have upon occasion picked up a recording off my phone knowing that I was playing it and then edited that out but I've never accidentally recorded my phone not knowing that that's what was on my recording.

To my surprise I actually got one photo of the wren. All of my other photos are beautiful, in-focus pictures of branches and pine needles. I think I see diamonds sprinkled on its back (which would make it a Winter Wren), which I could not see in real life. It just lookedhomogeneously alldark brown. I will attempt to remove the useless first 30 seconds from the 3rd audio recording. https://ebird.org/checklist/S129533131 Thomas Geza Miko Claremont, Los Angeles County, California 909.241.3300 |
Tom Miko's third recording of the wren at La Mirada Community Park includes a song (https://macaulaylibrary.org/asset/539043461) that, when compared to the sonograms on Nathan Pieplow's blog from 2009 (http://earbirding.com/blog/archives/826) is a very good match for Winter Wren. So nice find Jonathan and good job Tom on recording the song. Tom Benson Secretary, California Bird Records Committee toggle quoted message Show quoted text |
Hi,
33.907022,-118.008672 I am at the top of the steep Hill that Jonathan described earlier this week. If you find the water park called splash, look for a very large plastic yellow and blue water slide. Directly underneath that water slide there is a hillside that is inside the park, proper, with extensive plantings of some kind of non-native plant that has small yellow flowers. This is quite an extensive planting of a couple of acres but walk uphill to the top of this hill where it meets the fence for the water park. I had good looks at the bird. Overall the bird seems very dark brown, but the throat seems contrastingly very pale. I looked and could not see diamonds sprinkled on its back, which I would expect for winter wren. I have obtained audio, but failed to obtain photographs because I had the wrong sitting on my camera and now the bird is mad at me and hiding. I'm going to walk around in the rain and look for the Pine Warbler for a while and then come back and see if I can get photos to supplement the audio. Tom I left my reading glasses in the car so I hope that what is on this email actually makes sense and doesn't look like drunk typing Thomas Geza Miko

Birders, I would encourage anyone who goes to look for this wren to try to obtain good recordings of its calls, preferably calls given naturally and not in response to playback. And if you do, please upload them to eBird or submit your documentation (presuming it is a Winter Wren) to the CBRC:https://www.californiabirds.org/report_sighting.html.

I just had a Winter/Pacific Wren at La Mirada Park. It was along the fence of splash in the dense bushes. It was right at the top of that Hill. I have a recording but I don't have time to analyze it at the moment as I have a meeting I am rushing to. It did respond very aggressively when I played a Winter Wren call in the field.

Hi Birders, Had an interesting Pacific/Winter wren this morning near the waterfall at LA County Arboretum. It was giving a chatter call very similar to the recording for Winter Wren on Sibley v. 2 and was very light in the throat and breast. Unfortunately I didnt get a recording. Heres a link to a photo and coordinates. I havBird was present for a couple minutes, perching upright in the open oddly enough. I stuck around for a bit but it didnt reappear. http://www.inaturalist.org/observations/38431832 Good birding, James Maley |

Far fewer birds were present in the nooks and crannies in and around Palos Verdes golf course and environs today as compared to recent counts. The only real highlight was a briefly calling but unseen Winter/Pacific Wren in the creek below St. Francis church. It responded to pishing with three dry, rapid, doubled chips before shutting up. I'd be hard-pressed to compare the calls to another bird species, but it definitely didn't bring Wilson's Warbler to mind. I think it would be worthwhile for someone with a fancy-schmancy smartphone to play Winter Wren calls at this bird. It was about halfway between the church's fenced-in playground and the east end of the riparian area. In that area, I jammed a trailside stick into the ground and topped it with an upturned Boyd's (appropriate) coffee cup. In the creek-bottom near where I heard the bird, there was a notably tall, straight fan-palm. Also in this area were 3 Purple Finches, a Bullock's Oriole, and a Red-breasted Sapsucker.

Birders, The CBRC has officially accepted the Los Angeles County record of Winter Wren (Troglodytes troglodytes), a bird seen and heard calling on Pt. Dume, Malibu on 18 December 2005. This adds a new species to the Los Angeles County list (recall that Winter Wren and our expected Pacific Wren were split a couple of years back), and by my calculations pulls us back in front of San Diego County by one species. May the spring bring good birds to both counties. Kimball Kimball L.

Coverage: Los Angeles County, Ventura County -Transcript This is the Los Angeles Rare Bird Alert for Thursday, December 9. The male EURASIAN WIGEON continued through December 4 along the LA River in Glendale, adjacent to the Bette Davis Picnic Area at the corner of Victory and Riverside. As of December 7, the LONG-TAILED DUCK and one female/immature BLACK SCOTER continued in the Surf Scoter flock off Dockweiler State Beach in El Segundo. View with a scope from near lifeguard station #58. Access this area from the Hyperion parking lot between Imperial and Grand. Another WHITE-WINGED SCOTER was seen off Santa Monica Beach on December 7. An adult male WHITE-WINGED SCOTER was at the north arm of Pyramid Lake on December 4 along with a few COMMON GOLDENEYES. Exit the 5 Freeway at Smokey Bear Road, cross under the freeway and turn left to the fee station. Quail Lake off Highway 138 east of the 5 Freeway had a female RED-BREASTED MERGANSER and very few COMMON GOLDENEYES- 13 to be precise- for that area on December 4. HOODED MERGANSER numbers had reached 17 (about half being males) at the El Cariso Golf Course in Sylmar. The pond where the birds are can be viewed from Eldridge Ave. southeast of the golf course entrance. A third year BALD EAGLE continued at Bonelli Regional Park in San Dimas through December 2. The juvenile BROAD-WINGED HAWK continued at the Sepulveda Basin in Van Nuys through December 8. It has been in the southwest part of the field that lies just northeast of Burbank and Woodley. An ANCIENT MURRELET was in the Ballona Channel below the Pacific Ave. bridge from December 5-7. The YELLOW-BELLIED SAPSUCKER continued through December 8 at Ed Vincent Park in Inglewood. Look for it near the Warren Lane parking lot exit, though it does move around the area. The LEAST FLYCATCHER at DeForest Park in Long Beach continued through December 8. It has been in the area just south of the tennis courts and park building and can usually be located by its call. A GRAY FLYCATCHER continues at Hahamongna Watershed Park in Pasadena. It is being seen north of the lower parking area along the dirt road/path on the east side of the oaks. The EASTERN PHOEBE at Harbor Regional Park in Wilmington was reported through December 8. It is being seen near the dam along the south end of Lake Machado, and nearby in the riparian area and near the observation tower. Another EASTERN PHOEBE was at Malibu Creek State Park along the Braille Trail on December 2. It was also seen in the adjacent field and by the path that runs along the creek, all fairly close to the parking area. A PACIFIC WREN (recently split from WINTER WREN) was in Big Santa Anita Canyon above Arcadia on December 4. The bird is along the Gabrielino Trail past Sturdevant Falls and just below where the trail crosses the stream and there is a small waterfall. What was presumably (but not positively) the same bird was later seen upstream by the Cascade Picnic Area. A first year NORTHERN PARULA was at Oak Creek Park (aka La Mirada Creek Park) in La Mirada on December 7. To get to the location where this bird was seen, park on Los Flores and walk under Imperial Highway, crossing the first pedestrian bridge. Bear left and then up to where a broken pipe is leaking and a number of empty bottles are strewn about and check this general area. The immature male PINE WARBLER at Hansen Dam in Sylmar was seen through December 8. Take the Osborne exit from the 210 Freeway and head southwest to the Sports Center parking lot which is just off Foothill Blvd. The bird has been in pines east of the parking lot and more often downhill from the parking lot by the circular amphitheater. A SWAMP SPARROW was at the northeast corner of Holiday Lake in the west Antelope Valley on December 4 along with four CACKLING GEESE and two flyover SNOW GEESE. Take La Petite Road north from Highway 138 and go right on Elise, then east on West Ave B-8 and left on Calcot. A male SUMMER TANAGER was at LA National Cemetery in Westwood on December 8. It was about 200 feet south of the T intersection of Shiloh and Antietam. A COMMON GRACKLE was found at Earvin Magic Johnson Recreation Area in Willowbrook on December 9. It was seen in the grackle and blackbird flock around the south lake. Early morning or late afternoon may be best as the flocks tend to disperse during the day. On the island in the south lake was an immature female VERMILION FLYCATCHER, also on December 9. VENTURA COUNTY At the Saticoy Spreading Ponds, two SNOW GEESE and a ROSSS GOOSE were present on December 3. An immature TUNDRA SWAN was there on December 4. A BALD EAGLE was at the end of Arnold Road on December 8 along with a continuing AMERICAN BITTERN.

Hi all,
I had a nice hike with Lance Benner and Kathi Ellsworth this Saturday morning in
(Big) Santa Anita Canyon. The highlight was a Pacific wren (western variety of
winter wren). Lance found it on the way up, at 8:40 AM, and Kathi found it on
the way down, at 11:00 AM. Although difficult to find initially, it was seen
well and photographed. It was mostly silent, but responded to a recording with
a few "chimp" calls. The location
is approximately 34.215 deg N, 118.022 deg W ("34.215,-118.022" in Google
maps). This is on the Gabrielino Trail past the top of Sturtevant Falls, part
of the way toward Cascade picnic area and Spruce Grove campground. At one
point,
this trail crosses the stream from the east side to the west side and climbs
high into drier side canyons to the west of the stream. The bird was below
this stream crossing, perhaps by 100-200 yards. There is a small sloped
waterfall
there, also a remnant stone wall at a small trail switchback, and the bird was
seen
both above and below the waterfall. It was ducking into and out of the English
ivy, giving us occasional views.
We also saw an American dipper on the stream above Sturtevant Falls. On our way
up,
it was in the vicinity of green emergency call box #8, and on our way down, it
was in the more typical area nearing the falls.
There were two golden-crowned kinglets at Spruce Grove Campground.

Just so folks know, I wasn't being pedantic in my last post by saying Pacific Wren. It's a done deal according to the AOU, a split of Winter Wren, and should appear in the checklist this month. For other upcoming changes, see: http://www.aou.org/committees/nacc/proposals/pending.php For differences in vocalizations between Pacific and Winter Wrens, see: http://earbirding.com/blog/archives/1437 Cheers, Walter Szeliga Canyon County, CA |
