Date   
San Dieguito Monthly Bird Count - next Sunday, June 3rd.

Jayne Lesley
 

This is a reminder that the next San Dieguito monthly bird count is on the first Sunday in June - next Sunday, June 3rd.   Everyone is welcome - interested, beginners, experienced. 

We will meet at the usual time and place: 7:30 AM at the south end of San Andres. (Turn right/south off of Via De La Valle, on the east side of I5. San Andres dead ends at the San Dieguito Lagoon.) We coordinate with park rangers to provide vests and access for the restricted areas. We'll divide into five groups to count the different areas.

We gather to tally our results at noon at the Del Mar Public Works parking lot/picnic tables off Jimmy Durante Rd.

Hope to see you next Sunday for another great day of birding.

Possible first year male Summer Tanager at Stonewall mine Friday 05/25/2018

terry hurst
 

Hello all,

Today I spotted what I believe was a Summer Tanager on the west side of the road that leads up to the mine from highway 79. GPS coordinates: Google Maps

 It was found about midway from the highway up to where the road forks leading to the mine parking lot and the gate which leads into the horse group camp. Photo in this eBird list.

 
Was unable to get a good shot of the bird, because of the distance but I believe I took a shot good enough for a definitive ID. The bird had a large beak, no detectable wing bars that I could see,  red on the head and some red coming in other areas of the vent and breast which would eliminate the Western Tanager. I don't know what else this bird could possible be.

Dead hawks

Martha Wild
 

I sadly report that three red-shouldered hawks were found dead this week in East Switzer Canyon. The last one was seen by a children’s playgroup, and sat in a tree all day above where they were. The next day it was dead under the tree. The children found the others as well. It appears as if they all died from rat poison. One was definitely a juvenile, one an adult, the other unsure as mostly feathers were left, though there seemed to be a lot of very downy feathers, so maybe also a juvenile. The last few years I’ve birded this canyon and watched probably this very red-shoulder family raise a healthy brood each year - last year they had 3 strong young ones. There is a neighbor in the canyon who has a rat box outside there house that contains poison and the pre-school leaders are hoping to talk sense into this person and get it removed. They seem to feel that the dose isn’t enough to kill anything other than the rats. And it’s so stupid, the hawks do more to keep the rat population down than they are aware of, and without them they’ll have even more.

Any ideas on any action that could be taken to ban rat poison from being used in San Diego?

MIA chimney swift

Friday morning there was far less cloud cover, especially of the low drippy variety, compared to what the weather forecast called for, and as a result there were far fewer swallows and swifts in the TRV. We had three Vaux's still present, and distant looks at a soaring chateura, but certainly nothing overly intriguing, and the numbers are way down. Given that the forecast calls for increasing sunshine and warmer temperatures over the next few days, that will certainly not help at all in any swift searches until the weather becomes gloomy gray again.

At the bird and butterfly garden, the female hermit warbler continues as do four Townsend's warblers, one of which has an injured wing and is likely incapable of long-distance flight, so it will be interesting to see how long it continues there in the silk oaks. Two female Lawrence's Goldfinches continue as well.

Peregrine falcons, Torrey Pines

 

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 <dpovey@...>
 

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.

Rose-br Grosbeak, Summer Tanager, Reddish Egret, miscellanea

lehman.paul@verizon.net
 

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!
