Peregrine falcons, Torrey Pines

Robert Sommers
 

There are four babies this year. They started to fledge early this week. Only one of the four young birds is still in the nest/cave as of yesterday afternoon. I took photographs with Larry Moskovitz yesterday, including a juvenile which you can see here.
On the negative side, many of the last Torrey Pines near the cliff that were seemingly healthy last year have now died due to the borer beetle infestation.

Chimney Swift update.

David Povey
 

The Chimney Swift found by Paul Lehman was present in the Tijuana River Valley again this morning.

First seen briefly, and solo on west of Dairy Mart Road between the south and middle ponds. Then 15-20 mins.

later it gave longer, more satisfying looks on both sides of the  Dairy Mart Rd bridge over the river, for a number of observers.

The Chimney Swift there with a half dozen or so Vaux Swifts, and many swallows.  Very slightly larger, differing flight

style, and missing, damaged or molting some flight feathers, assisted in picking out this bird.

 

Other spots in the valley had a few late migrants. A female Western Tanager was in the Silk Oak at the park headquarters.

A female Hermit Warbler was in the Bird and Butterfly garden, as was Swanson's Thrush, several Townsend's Warblers

Yellow Warblers, and the like.  A male and female Lawrence's Goldfinches are still present. The female appeared to be

collecting nesting material.

Thursday morning, the 24th, a so-so number of migrants in residential Point Loma included a male ROSE-BREASTED GROSBEAK, on the move northward, near Silver Gate and Warner, and a singing SUMMER TANAGER on the PLNU campus. The "best" western migrant was a rather late male Black-throated Gray Warbler, which ties the late spring migrant date published in the SD Atlas. To give an idea of what's on the move now in late May, here are the other migrant totals:  W. Wood-Pewee: 3, Pac-slope Flycatcher: 1, Warbling Vireo: 4, Yellow Warbler: 10, Townsend's Warbler: 5, Wilson's Warbler: 5, Western Tanager: 5, Lazuli Bunting: 2 (getting a bit late).  Also today, there's a young REDDISH EGRET in the San Diego River channel adjacent to Sea World.

Brown Boobies continue to be seen in the early morning scoping offshore from the south end of Seacoast Dr. in Imperial Beach, where there were also a couple lingering Parasitic Jaegers a few days ago. At least 2, maybe 3, pairs of Yellow-crowned Night-Herons nesting in the I.B. Sports Park. A total of 70 W. Sandpipers yesterday at the saltworks pond at the end of 13th St. is a good total for this late in the month. Several Redheads at San Dieguito Lagoon in Del Mar are at the site where nesting has taken place several of the past years, but lower water levels this year due to inadequate rainfall may mean poor success. And speaking of "lingering" waterfowl...there aren't many! Some late stuff at scattered coastal sites the past week includes a single "Black" Brant, 1 Northern Shoveler, and several American Wigeon. There may still be a Bufflehead at Robb Field.  But not a good lingering duckie showing this season.

Chestnut-sided Warbler in Anza-Borrego Desert May 23, 2018

Britta Lee Shain
 

At 9:10AM this morning there was an adult male Chestnut-sided Warbler bathing at a water feature in our backyard in Vallecito (south end of the Anza Borrego Desert State Park). 4 Photos and checklist at ebird.org: https://ebird.org/view/checklist/S45965659

Other sightings today included female Tricolored Blackbird, female Blue Grosbeak, Willow Flycatcher, Ash-throated Flycatcher, along with 6 or 7 Yellow Warblers, a couple of Wilson's, Orange-crowneds, Warbling Vireos, male and female Townsend's, Bullock's Orioles, Western Tanagers and a pair of nesting Hooded Orioles. (This is not a complete list).

On May 21st, in the morning, we had a visit from an adult male Rose-breasted Grosbeak. He stayed through the day, until dusk, but did not return the next day: https://ebird.org/view/checklist/S45867727

And, on May 2nd, we had our first ever Hermit Warbler at this location. 1 photo adult male : https://ebird.org/view/checklist/S45974150

Can't wait to see what tomorrow brings ... :)

White-winged Scoter and Lawrence's Goldfinches on Wednesday, 23 May

Barbara
 

Other birds of note this morning, 23 May:  After seeing two Bank Swallows and the Chimney Swift with 8+ Vaux's Swifts, four of us continued to the Bird and Butterfly Garden. One getting-late migrant  female Hermit Warbler was seen there along with three Lawrence's Goldfinches. Small numbers of Townsend's Warblers and Western Tanagers continue widespread.

Nancy Christensen and I continued to the coast to look for the female White-winged Scoter that Paul Lehman reported last week. We found it in the dwindling flock of Surf Scoter ( today's count was ~75, down from 150 last week) approximately 1/2 mile north of Camp Surf. Camp Surf is accessed at the very northern end of Seacoast Drive and Carnation Avenue.

Good birding,

More on Chimney Swift

lehman.paul@verizon.net
 

At 8 a.m. the apparent ChimneySwift headed north from the bridge where a number of vauxs Swifts continue, and was last seen foraging over the general area of the middle Dairy Mart Pond and the main, large pond,  but swallows and swifts are working this whole area so it may well stay somewhere locally. Clearly one wants low overcast and cool conditions to keep the birds down low and in the area, as once the sun comes out and it warms up the birds should disperse. Anyone who wants to try for this bird it also would be recommended to do so only very early and late in the day as your chances are better at that time than during midday. One other character to look for is the bird tends to soar more than the vauxs swifts, as well as having somewhat  slower flaps. There may be even more than eight Vaux's Swifts around, which is a large number to still be present on the 23rd.

Apparent Chimney Swift in TRV

lehman.paul@verizon.net
 

There is an apparent ChimneySwift mixed in with about 8 Vaux's Swifts at 7:30-7:45 a.m. Feeding back and forth through the willows between the south end of the defunct sod farm and the Monument Road / Dairy Mart Road bridge in the Tijuana River Valley. Also check over the river channel itself. One needs to carefully study the Vaux's Swifts and pick out the one bird that is slightly larger, slightly longer and larger winged, and consistently slower flapping. Also perhaps shows a little more wear to the flight feathers then almost all of the Vaux's. It is fairly easy to continually get on the same bird time and time again once you get the search image down.

Also early this morning there were two Bank Swallows at the main Dairy Mart Pond but they disappeared after a while.

Barb Carlson, Nancy Christensen, and Eric Kallen and I saw it in this same silk oak later in the morning at about 11:30 or so, then soon after that at about 12 15, we spotted it feeding in Chinese elms in front of 3725 Dupont (the street parallel to and  just south of the silk oak alley)

Re: predator corvids

Geoffrey L. Rogers
 

Arlene and all,

 

Excerpts from The Birds of North America online account for American Crow. From this it seems that preying on full-sized (not young) passerines is limited but well known. Probably the same for ravens but I didn’t check the account for them. I’d be curious how far the crow flew with the sparrow.  

 

Omnivorous. Wide variety of invertebrates (terrestrial and intertidal marine); amphibians; reptiles; small birds and mammals

 

Carries food to nest in antelingual pouch at base of throat. Transports larger food items in bill (e.g., clams, Bayer 1984c ; American Robin [Turdus migratorius ] nestling; CC) or occasionally in feet

 

 Pursues small birds, such as European Starling (Sturnus vulgaris ; Cuccia 1984) and House Sparrow (Passer domesticus ; Putnam 1992) in flight, to catch and kill them.

 

Takes eggs and/or nestlings of a wide variety of birds, such as Common Loon (Gavia immer ; McIntyre 1977a); ground-nesting ducks (Kalmbach 1937b); Least Tern (Brunton 1997); Pinyon Jay (Gymnorhinus cyanocephalus ; Marzluff 1985); Western Scrub-Jay (Aphelocoma californica ; Verbeek 1973b); American Robin (CC); and Savannah Sparrow (Passerculus sandwichensis ; Wheelwright et al. 1997).

Hi all,

 

While pumping gas this morning I saw a crow attack a house sparrow in the street and fly off with it. Years ago I saw a raven take a White-crowned Sparrow. Is it pretty normal for these corvids to act like raptors? Is it a new behavior or has it been around for a while? Thanks!

On Monday morning the 21st, a Bank Swallow is hanging out at the main Dairy Mart pond, where there continue to be 6 lingering Vaux's Swifts overhead. The female Calliope Hummingbird continues its late-lingering ways at the Bird and Butterfly Garden at the huge bush with the pale blue flowers and adjacent blooming bottle brush.

May 20 San Diego pelagic trip: Manx Shearwater, B-f Albatross

lehman.paul@verizon.net
 

The May 20th San Diego 12-hour pelagic trip sponsored by Buena Vista Audubon Society aboard "Grande" out to the 9-Mile and 30-Mile Banks was highlighted by a MANX SHEARWATER, Black-footed Albatross, and good numbers of several offshore species. Unfortunately the Manx was a quick fly-by at moderate distance at the 30-Mile Bank and was identified only through study of the photos taken. The B-f Albatross put on a good show behind the boat, also at the 30-Mile. A Common Murre a few miles offshore was in alternate plumage and getting late. The large numbers of Scripps's Murrelets were made up almost entirely of pairs, but with zero chicks seen. Three Brown Boobies, scattered. Pacific Loons were still migrating northward. A few migrant passerines landed on the boat. Offshore totals for most (select) species seen included:

Black-footed Albatross:  1

Northern Fulmar:  1

Pink-footed Shearwater:  22

Sooty Shearwater:  700

MANX SHEARWATER:  1

Black-vented Shearwater:  24

Ashy Storm-Petrel:  7

Black Storm-Petrel:  250

Brown Booby:  3

Pacific Loon:  25

Red-necked Phalarope:  70

Common Murre:  1

Scripps's Murrelet:  120

Cassin's Auklet:  25

Sabine's Gull:  10

Heermann's Gull:  1

Least Tern:  25

Elegant Tern:  450

Pacific-slope Flycatcher:  1

Warbling Vireo:  3

Townsend's Warbler:  4

Wilson's Warbler:  4

Fin Whale:  2 or 3

There will be another late-spring trip--also 12 hours--on June 10th, still with available space. See sandiegopelagics.com for details.

FRNC & Mt. Soledad – Black Swifts more info & photos, May 20, 2018

Gary Nunn
 

Some further additional notes here on BLACK SWIFT sightings today from Fort Rosecrans National Cemetery, Point Loma and Mt. Soledad, La Jolla.

120 Black Swifts seen today!

I almost quit Fort Rosecrans this morning after a very dull and chilly morning birding from 6:30am and seeing very few birds.  A cool south breeze was gently blowing and low thick marine layer kept the temps down.  Then at 9am I spotted a BANK SWALLOW with the resident Barn Swallow flock feeding over the Ficus trees which are fruiting, one or two trees heavily so, and seem to have a good supply of flying insects nearby.  Nice!  This was just east of the Committal Shelter on east side.  Then 7 PURPLE MARTIN came flying by me heading south towards the point!  I managed to snag some poor photos and thought they might return but only saw another single bird about 90 minutes later.  Then just as that was happening I spied the first BLACK SWIFT at 9:10am.  Then followed singles at 9:16am, and 9:28am.  Then small groups started appearing 3-5 strong, with a maximum size group of 12 birds.  Total count was 39 individuals in just under 2 hours.  All birds approaching from the south and right over or visible from the highway.  Viewed from the highway just south of the Committal Shelter.

I left the cemetery just after 11am for a lunch date with my family in La Jolla but got a call on the way that plans had changed and a delay!  No problem so I stopped at Mt. Soledad of course.  As soon as I walked up to the area around the cross I looked straight up and had 10 BLACK SWIFT circling overhead at 11:58am!  They did this for a minute before climbing very quickly in elevation and disappeared north.  I waited around and had another single bird pass east to west.

After lunch I was driving by Mt. Soledad on way home and of course stopped again!  Within a few minutes a flock of very low flying 15 BLACK SWIFT went by east to west.  Waiting some more and I suddenly heard unmistakable swift chittering calls.  There were no swifts in sight anywhere then suddenly a flock of 40-50 just cruising low up the east side of Mt. Soledad and right overhead calling.  It was pretty amazing to see filling the sky overhead with swifts and watching them arcing over the top of the hill chasing each other!  I was a bit paralyzed just seeing so many at once but did shoot off some frames getting a photo with 14 in the frame at once as they left going west!  Then a longer wait and another group of 15 at 3:39pm.  At least 70 in total this session.  These groups all passing east to west, slightly obliquely coming in from same or just lower height than Mt. Soledad, rising over the peak or sliding by at eyeball level on the north or south sides.

I put lots of photos in the three eBird checklists here:

Fort Rosecrans National Cemetery https://ebird.org/view/checklist/S45882702
Mt. Soledad afternoon (14 bird frame here!) https://ebird.org/view/checklist/S45882863

One of those days birding you never forget!

Just had group of at least 40 Black Swifts pass low over Mt. Soledad, La Jolla at 3pm. Heard calling chittering in the flock so close - amazing!

Also a group 10-15 about 2:50pm here.
