Re: Miramar National Cemetery hotspot

Matt - if there are hours restrictions at this hotspot like at Rosecrans, it might be good to include those in the hotspot name so folks are aware.

Pectoral Sandpiper at San Diego PoloFields

Dan King found a Pectoral Sandpiper this morning 10/6 at the Polo fields. It continues and is now by itself in the north west corner feeding on the wet grass. This is near the modular buildings. Still present at 11:30 AM

Continuing BT Blue Warbler - San Dieguito County Park

King, Dan
 

For anyone who has not had their fill of male Black-throated Blue Warblers in the county this fall, the bird reported yesterday evening by Patrico Shipley at San Dieguito County Park continues this morning Oct 6 at the same location described in his eBird checklist, pasted here:  https://ebird.org/checklist/S95659406
 
The bird was in the liquid amber/sweet gum trees directly across the sidewalk from the drinking fountain described in Patrico’s checklist.

SD Automated Big Day

Kyle Fischer
 

Hello,

In the spring of 2020 I became curious if eBird data could be used to automatically generate a decent big day route for San Diego County.  Since then I've put together an algorithm that optimizes a route based on a probabilistic model of bird frequency at all San Diego eBird hotspots.  This algorithm, or a version of it, was used to generate routes I ran for big days in October 2020 and May 2021.  Both runs generated decent numbers, despite  several day-of snafus.  More importantly, the number of species found was very close to the numbers the algorithm predicted for both routes, suggested the model was pretty good.  As far as I know this is the first time a big day has been planned and executed based entirely on raw data.

In anticipation of eBird's October Big Day, this Saturday, I'll be posting the route generated by the algorithm here, on Friday evening ~7pm.  If you end up using this route for a big day this weekend, PLEASE let me know.  It would greatly help me update and improve the system (and hear about your exploits).

If you're skeptical of the claims coming from a big day team of one (and you definitely should be), please check out this verbose explainer on how the whole thing works and what I learned along the way.

If you have any questions please feel free to reach out.

Happy birding,

Kyle


Re: Possible hybrid vireo

Thanks for helping with the ID. I have seen Swinhoe's White-eye in Orange County. It's been a good while since then and that didn't come to mind.


Possible hybrid vireo

Rod Jimenez
 

While birding on Saturday, 10/2 at Buddy Todd Park, I observed an apparent Cassin's Vireo, based on the overall coloration and spectacles, in a ficus tree near 33.207396, -117.348265. What was odd about this bird is that it had a yellow chin, as seen in this photo: https://bird-photos-rj.s3.us-west-2.amazonaws.com/vireo.jpg, and yellow undertail coverts. Unfortunately, the only good photo that I have does not show the undertail coverts. Any thoughts or input on an ID would be helpful.

Bobolink continues.

The Bobolink found earlier by Matt S. is continuing in the west corner of the Miramar National Cemetery. Turn left at the flags, and it’s in the section of the plots on your left.

Orchard Oriole, Little Stint, miscellanea

lehman.paul@verizon.net
 

This morning, Tuesday the 5th, there was a female/immature Orchard Oriole in the TRV community gardens on Hollister Avenue, at first hanging out with House Finches and White-crowned Sparrows in the western part of the gardens. Almost blended in with its buddies due to its rather small size. Also in the gardens are 1-2 Green-tailed Towhees, likely continuing and perhaps returning birds from last winter, and 1-2 continuing female-type Lawrence's Goldfinches. A female-type Vermilion Flycatcher is (continuing?) at the Sunset ball fields. Elsewhere, I had a Willow Flycatcher, which is about as late as one sees them in fall; a W. Wood-Pewee, which is getting near the end of their season; Swainson's Thrush; and MacGillivray's Warbler.

The Little Stint continued on "Stint Island" early this morning, with plenty of Westerns, and it should be mentioned that it is just very slightly darker than the basic-plumaged Westerns, as it has slightly darker feather centers to the wing-coverts and scapulars than do the basic Westerns which don't show these darker centers and which gives the stint a subtley "marbled" appearance. It also has slightly darker breast sides than do the basic Westerns. But be aware not only of the continued presence of some partly-juvenile Westerns but also that there are also often 1 or 2 Least Sandpipers present, which are smaller, smaller billed, and darker than the Westerns, and often one cannot make out the yellowish legs, and which have been turned into the Little Stint more than once over the past several years.

Black Swift fly by @ Mt Helix (Oct 5, 2021)

Eitan Altman
 

Around 9:45am a single BLACK SWIFT flew past Mt Helix (looking E) at high altitude barreling south.

It was tracking (in the reverse direction) essentially the same route that I had a few heading N this past May, heading roughly SW across the saddle over the hills S of El Cajon (between Mt Helix and Rancho San Diego) heading towards Sweetwater Reservoir / Dictionary Hill.

Re: Blackburnian Warbler and continuing American Redstart at Cottonwood Creek

Gjon Hazard
 

BLACKBURNIAN and AM REDSTART continued this morning (10/5; 7:20 to 8:00) at Cottonwood Creek Upper.

At first, Peter Ginsberg and I had both birds in a flock of warblers (a warbler flock! This alone is quite noteworthy in this part of North County so far this fall)… anyway, they were at first in the cottonwoods at the north end of the bridge and then the flock disolved, with the Blackburnian flying north, over the playground, into a sycamore. It then flew SW, back into the riparian proper, where we lost it. At that point I left.

Details to be added to eBird later.

Adding to the list of Blackburnian Warblers in the county this fall is a dull one that we found at Upper Cottonwood Creek this morning. It was high in the trees near the bridge. We refound Peter’s American Redstart near the beginning of the path that goes along the creek bordering the freeway.

We also checked the lower Cottonwood Creek where we saw the MacGillivrays Warbler found by Joe this morning. We had a tantalizing glimpse of a warbler with a thin, broken eye ring, gray head and yellow back before it disappeared into the thick undergrowth of weeds just west of the little wooden bridge. Perhaps it was Peter’s bird from Sunday morning but we couldn’t locate it again or definitely identify it as a Mourning Warbler. There was an immature male COYT in the vicinity that could have been playing tricks on me.

request for reporting of oiled birds along San Diego coast

Robert Patton
 

Given the mobility of waterbirds & current migrations, oiled individuals from the recent spill in Orange County are likely to be seen in San Diego as well.  Although there is no formal reporting platform for such individuals recovered or sighted outside of Orange County, Resource Agency staff rely on birders and the public to report such sightings for assistance in Wildlife Damage Assessment.  I encourage birders to include notes in their ebird lists or post here.  Seaworld or Wildlife Assist may be worth contacting for locally stranded oiled birds, unable to fly.  Reports may also be submitted to  Oiled Wildlife Care Network (phone: (877) 823-6926).

Black-throated blue warbler continues in the small ficus grove behind the two tennis court buildings.

Andy Rathbone
 

As of 3pm, it was staying near the top of the two trees closest to the buildings.

FYI update - the bird disappeared around 10:45 and hasn’t been seen in over an hour despite several birders searching.
