I just arrived back in the mountains and started counting on Saturday. Unlike other years, I will post them on www.trektellen 'Tejon Pass/Golden Triangle. Daniel Irons posted the count here a couple of years ago. For those who don't know, Trektellen is the global site where nearly all major migration counts are. Bear Divide has just started using it and I also do another count 'Del Haven' (my Cape May, NJ home) in fall. Numbers are live where there is internet (not here). This year, sadly, will probably be my last one and so I will try to be more transparent with information. I believe Tejon Pass and the general area is the best place in spring for visible migration (vismig)/morning flight in western USA. Geographically, it is so striking; multiple geographic features meet there. I bought a house based on google earth - it is so obvious! It is feed by birds migrating through (1)The Antelope Valley, (2) along the northern edge of LA Forest (Pine Canyon Rd/Quail Lake), (3) through the LA Forest (Old Ridge rd) - similar to Bear Divide, (4) LA Basin birds travelling up I5. These birds all meet at the Golden Triangle (I5/Gorman Post Rd/138 triangle) and fly up the pass when the wind has west in it: it is typically NW. Birds in the daytime always want to fly into the wind - with the wind at night. It is a big area and, unlike Bear Divide which has one funnel, there are lots of ways birds can move. Up the pass is the favorite. Anywhere along Gorman Post Rd where the slopes meet the road can be good, occasionally amazing! Birds sometimes cut over the back by the quarry and come out over Castac Lake just over the brow of Tejon Pass and just to the north of the services there. This can be a great place for raptors and I have seen as many as 6 Golden Eagles at once and is the way most Swainson's Hawks go. No single place is the best - a good, and bad, thing. Old Ridge Rd is great for solitude; the two passes before the old inn frame are the best. The bird composition is like Bear Divide though they are more spread out here. These birds exit the hills above Copco Rd (next to the i5/138 ramp). The tracks wind up into the hills from here and the tallest peak that looks down on I5 and Tejon Pass to the north is the best. Most birds drop down the valley from here, while others such as Townsend's and Hermit Warblers typically fly up into orbit. It is the end of the chaparral so there is no food for them below. Where do they go? That is the million dollar question! Most of the birds that drop cross Copco road, particularly at the start of it. This is the best place for flight photography - as they rise up to cross the 138 slip road. As for Gorman Post Rd - just look for the birds. If you look at these places on a map, it will make sense. Better still, visit, and really look around and think what you would do if you were a bird. Saturday started with 3000 Yellow-rumps. There have been decent flights each day since with good numbers of all 3 goldfinches, up to 500 Western Kingbirds, flocks of Chipping and White-crowned Sparrows, lots of swallow etc. More interesting have been several Hairy and Nuttall's Woodpeckers, Common Yellowthroat and Swamp Sparrow flying up the pass - birds less prone to visible migration. Orioles, Grosbeaks and other migrants are getting commoner by the day. If its warm with wind from the NW in the area, there are usually birds. The pass is usually very windy even when it is calm nearby. If it's easterly, stay in bed! Check www.trektellon/ Tejon Pass -Golden Triangle - the dates are top left to look at previous days.

I was just forwarded this message by a visiting birder who contacted via the LA Audubon website. Jon Fisher Glendale, CA I'm a visiting international birder and found two notable rarities along the LA River yesterday, Wednesday April 2nd. Please forward this to the local LA RBA for other birders to refind and document them, thanks. White Wagtail - An adult breeding plumaged "black-backed" race was feeding under the I-405 San Diego Freeway bridge at 11:45am. These are the two very busy traffic bridges with green trusses just north of the Wardlow Road bridge. Best viewing is from the east bank multi-use path and from north of the bridges as the bird remained hidden for extended periods, but favoring the low water and mostly dry concrete areas with blue trash debris at the western end of the river. Tropical Kingbird - A lone bird was heard and seen at Dominguez Gap Wetlands at the picnic ramada overlook in the southwest corner at 1:30pm.

Larry was a wonderful person and added much to all of our lives. A forward from Frank Gilliland... Ron Cyger Monrovia ---------- Forwarded message --------- Dear Los Angeles Birders Members, It is with deep sadness that I share the news of the passing of our friend and fellow birder, Larry Allen. Larry passed away peacefully at approximately 5:00 AM this morning Larry was a Life Member of Los Angeles Birders and a pillar of our community. He was widely respected for his expertise on parrots and gulls, and he generously shared his time and knowledge with all of us. As the lead author of the Los Angeles County Bird Atlas, Larry’s contributions to our understanding of local birdlife were immense. At this moment, we do not have information regarding a celebration of Larry’s life or plans to honor his legacy. We will share further details with you as they become available. Sincerely, Frank Gilliland Vice President, Los Angeles Birders

Just picking up my kid at SPHS, Olguin Campus and a Bald Eagle flew overhead, being chased by gulls! Fabulous! Jeanette Repp San Pedro, CA -- Jeanette Repp San Pedro, CA

In recent years, California has experienced some of its worst fire seasons in recorded history, with megafires becoming more severe and more frequent. Despite these shifts, fire remains an essential component of California landscapes and the species that reside within them by creating new habitat and creating new food and nesting resources for animal species. We use acoustic monitors to understand how bird and bat species respond to the 2018 Mendocino Complex Fire to examine how these groups respond to fire in oak woodland and shrubland landscapes. We find that fire actually improves habitat and the presence of several bird species highlighting the key role fire continues to play in California ecosystems and its increasing significance in ongoing wildlife conservation planning. Dr. Kendall Calhoun is currently a postdoctoral researcher at UC Davis (Department of Wildlife, Fish, and Conservation Biology) and UCLA (Department of Ecology and Evolutionary Biology). His research examines how ecological disturbances influence wildlife community assemblages and resilience. Building ecosystem resilience is an essential conservation strategy amidst ongoing global change. His work also seeks to understand the potential consequences of climate change and disturbances in altering dynamics of human-wildlife conflict. His aim is to inform future research and management decisions to create more resilient ecosystems now and into the future.

Greetings Everyone, The purpose of this email is to provide a quick update on Swainson's Hawk migration through this area and to invite you to join us on picket lines on Sunday, March 23, to try to understand their migration routes better. I've been keeping track of all the Swainson's hawks reported in eBird west and north of Borrego Springs and Palm Springs this month, and to date, more than 1150 Swainson's hawks have moved through the area. However, there have been fewer large groups of hawks seen moving along the foothills west of Glendora relative to previous years, perhaps due to more clear days when they could be flying higher where they are harder to see and/or flying over the San Gabriel Mountains where there are very few observers. Reports dating back several years have documented the birds flying into the mountains over Glendora Ridge during sunny weather; more birds are seen west through Pasadena when low clouds are present. On March 23 we'd like to invite you to help us check sites along the foothills _and_ in the San Gabriel Mountains. In 2023 and 2024 when we tried this the roads in the mountains were closed, so observers spread out east-west along the foothills, but this year we want to augment this by setting up a line in the mountains in addition to checking sites east-west along the foothills. Currently the Angeles Crest Highway is open on the west from La Canada-Flintridge to Islip Saddle on the east. Route 39 is also open north of Azusa up to the Crystal Lake area but not all the way up to Angeles Crest (the northernmost 4 miles of highway 39 are closed to the public). Unfortunately, the Glendora Mountain and Glendora Ridge Roads are closed. We don't know in detail where the hawks go once they get into the mountains, so we'd like to position observers along highway 39 north of Azusa and along the Angeles Crest Highway east of Clear Creek Junction (where the Crest and the Angeles Forest Highways intersect) to watch for hawks from 9:00-11:00 on March 23. We suspect that sites east of Red Box Gap might be more likely to have hawks, but we don't really know. We can't guarantee that hawks will migrate over any specific location, but it we won't know if we don't try. If this might interest you, please feel free to contact me if you have a site you'd like to check; if not, I can suggest locations, although pretty much any spot along the road with clear views to the south and east could work well. Locations along the Angeles Forest Highway might also be worth checking (say, Mill Creek Summit). It's also fine if you just head up there and report back later. Bear Divide could also be worth checking even though it's farther west. I'm planning to watch from Shortcut Saddle near mile 43 on the Angeles Crest Highway. We also welcome reports from observers along the foothills from the Palm Springs area on the east all the way to the Grapevine on the west. It would be particularly helpful if someone could cover Glen Helen Park to see if the birds are moving through the Cajon Pass. Of course, observations from the Antelope Valley and anywhere else in the greater Los Angeles area are also welcome. I'll provide an update early in the week to indicate what happened and what we learned. Thank you! Lance Lance Benner Pasadena, CA On behalf of Los Angeles Birders

Hi Everyone, There were multiple reports of 100+ Swainson's hawks at Borrego Springs today (March 15). Chances are good that many will move over western Riverside and San Bernardino counties on Sunday and possibly over Los Angeles County later in the day. There were multiple reports of hawks today from Juniper Hills (Kimball Garrett) on the north side of the mountains and in Claremont (Cathy McFadden and Paul Clarke). There were also pulses of migrants in the area on March 10 - 12 during breaks in the storms. Good numbers of turkey vultures continue to move through as well and many were moving along the foothills in northern Pasadena this afternoon.

Hi Everyone, Here's an update on the Swainson's hawk and turkey vulture migration across the greater Los Angeles Area. There have been a modest number of reports of five or more Swainson's hawks reported across Los Angeles County and western San Bernardino Counties so far in recent days. Here's the most recent list, which I compiled earlier today (Sunday, March 9): N Date Location Observer 170 Mar 5 Bonelli Park Keith Condon 80 Mar 5 Bonelli Park, 2nd group Keith Condon 20+ Mar 6 0755 Hahamongna Park Jeffrey and Mary Fenwick 12 Mar 6 0935 Hahamongna Park Jeffrey and Mary Fenwick 55 Mar 6 1227 East Upland. Two groups Mike Brossart & Kitty Blassey 5 Mar 6 1500 70th W/Ave L8, Antelope Valley Kathy Duret 75 Mar 8 1603 Rancho Santa Ana Botanic Garden Dani and Douglas Lippoldt 5 Mar 9 0903 Senwood Way, Fallbrook Kenneth Weaver (San Diego County, coastal slope) There have been numerous other Swainson's hawk reports from LA, San Bernardino, western Riverside, Orange, and coastal San Diego Counties, all with less than 5 individuals. Counts at Borrego Springs in eastern San Diego County have picked up with multiple reports of dozens of birds (or more). Tonight about 125 hawks were reported in that area, so they might move west over western Riverside, San Bernardino, and Los Angeles County on Monday. There have also been many recent reports in the Imperial Valley south of the Salton Sea, some with dozens of birds. Significantly larger numbers of turkey vultures have been on the move in recent weeks. Yesterday I pored over eBird records for Los Angeles County and tabulated every list since February 1 that reported at least 20 vultures. Here's what I found: N Date Location Observer 25 Feb 4 Piute Ponds Kimball Garrett 50 Feb 6 Pomona Colleg Mark Price 70 Feb 6 Butte Valley FlowerSanctuary William Watson 42 Feb 6 Santa Fe Dam Mickey and Jan Long 40 Feb 8 PCT near Tehachapi Alan Brelsford 48 Feb 8 250th E/Adobe Mountain Kimball Garrett 43 Feb 8 Quail Lake Pasadena Audubon Trip (multiple groups of birds) 24 Feb 11 Claremont Village Michael San Miguel 32 Feb 14 Juniper Hills Kimball Garrett 34 Feb 16 Near PCT/Mojave Alan Brelsford 25 Feb 16 Creston Dr, Hollywood Helen Butts 22 Feb 17 Big Dalton Canyon Patrick Gavit 58 Feb 18 Piute Ponds Kimball Garrett 49 Feb 19 Sandberg Brad Rumble 40 Feb 23 90th E/Ave F8 Lance Benner 27 Feb 23 250th E/Adobe Mountain Chezy Yusuf 25 Feb 23 Butte Valley FlowerSanctuary William Watson 36 Feb 23 Malibu Creek State Park Matthew Webb 52 Feb 23 Hansen Dam Nathan Barkley 27 Feb 24 Descanso Gardens Jeffrey and Mary Fenwick 30 Feb 26 101 near Sepulveda Basin Anonymous 27 Feb 26 Hansen Dam Nathan Barkley 22 Feb 27 Hahamongna Park Jeffrey and Mary Fenwick 70 Mar 1 Butte Valley FlowerSanctuary William Watson 35 Mar 1 Lake Piru Carter Strope 23 Mar 2 Walker Ranch, Placerita Cyn Mark and Janet Scheel 20 Mar 2 Hansen Dam Nathan Barkley 23 Mar 2 Hansen Dam Brad Rumble 25 Mar 3 Crystalaire Ruth Gravance 33 Mar 3 Pinyon Road, Llano Anonymous 40 Mar 3 Two Strike Park, LaCresenta George Faeustle 30 Mar 5 Bonelli Park Keith Condon 41 Mar 6 Hahamongna Park Jeffrey and Mary Fenwick Kimball Garrett mentioned that one of the vultures he saw in Juniper Hills had a red or orange patagial tag, so please be on the alert for those, and if you see some, try to read code on the tag and report it in your eBird lists (and on the listserves). Finally, large flocks of other large birds are also migrating inland. For example, on Saturday, Naresh Satyan and I saw a flock of about 150 California gulls thousands of feet over La Canada-Flintridge and moving toward Mt. Lukens. The birds were strung out in a broad crescent and were visually striking against a deep blue sky. Regards, Lance Lance Benner Pasadena, CA On behalf of Los Angeles Birders

Hi Everyone, The first big flocks of Swainson's hawks this year were reported at Bonelli Park in San Dimas this morning (Wednesday, March 5) by Keith Condon, who saw ~170 and ~80 birds in separate groups. We're going to monitor the hawk migration again this year and hope to set up one or more picket lines later this month after activity increases. Once again, I'll be providing updates on groups of 10 or more that are reported on the listserves and/or on eBird. I'll provide more background information about the migration soon in a separate email, but for now, given that some of today's hawks were seen shortly before it begain to rain, the birds may have landed in the rain and could still be in the area long the foothills west of San Dimas. It could be productive to keep a watch tomorrow (March 6) along the foothill corridor. In general, it appears that low overcasts can keep the hawks relatively low where they are easier to see while migrating west/northwest. Oddly, reports of large groups of hawks from Anza-Borrego, where the birds often stage, have been sparse this year, so perhaps the hawks seen over Bonelli took a different route (perhaps farther east through the Imperial Valley?). Also watch for migrating turkey vultures, which have already started moving through in good numbers. There was a large flock over the foothills this past weekend, a steady stream was moving past northern Sierra Madre on March 2 around noon, and on Feb. 22 I saw a kettle of 40 vultures over the Antelope Valley at 90th E and Ave. F8.
