Blackpoll Warbler at Santee Lakes

The adult male Blackpoll Warbler found by Eitan (5-7-18) continues at Santee Lakes.  First heard and later seen in the Silk Oaks along the east side of the park, just north of the island/bridge at Lake 4. The warbler spent its time foraging in the silk oak and across the driveway in a Coast Live Oak.

It was reasonably bird this morning.  Pretty much the same selection of common western migrants that we've been seeing recently. Lots of Townsend's Warblers especially.

What kind of documentation should one submit to the CBRC? Following are some guidelines for submitting media and written descriptions that will be useful for helping the CBRC evaluate records and archive documentation. Documentation may be submitted directly to the secretary via email (secretary@…) , or by using the online submission form (http://www.californiabirds.org/report_sighting.html).

 

Media: This includes photos, audio recordings, and video. Photographs are usually the most useful documentation for evaluating records. If you have reasonably good (=identifiable) photos, please submit them. If possible, please crop the photos before submission so that the bird fills most of the frame. Also, please send originals whenever possible, and not screenshots or back-of-camera photos. How many photos should you submit? That really depends on the record. If it is a long-staying rarity that is easily identifiable and seen by dozens of people, then a few photos (1-3 per person) are sufficient. If it is a mega-rarity that is difficult to identify and only seen by a one or few people, then send as many photos as possible that show the bird at different angles, postures, lighting, etc. Sometimes it is also useful to submit audio and/or video recordings of the bird, as some birds are more easily identified by their vocalizations. If relatively short, most audio recordings are small enough to be submitted via email; please submit those along with a brief note indicating the date and location of the recording. Large audio files and video files can be submitted by using a file sharing service; please contact the secretary if you need to submit a file that is too large for email.

 

Written descriptions: Some written details should always be provided – even the best photos should be accompanied by the name of the observer, the date, and the location, at a minimum. Sometimes a photo can’t be obtained or vocalizations can’t be recorded. In some cases, behaviors might be noted in the field that aren’t preserved well by photos. In these cases, it is helpful to submit a written description of the bird. Ideally, this description should be written as soon after observing the bird as possible; it is often helpful to make written notes in the field, or even dictate notes into the voice recorder on your smartphone while observing the bird, from which you can later generate a written description. The most important aspect of a written description is that you report only what you observed, and not a general description of the bird from a field guide. At a minimum, your description should include the date and location of the observation, and a description of the bird (size and structure, plumage, vocalizations, behavior). A brief discussion of how the bird was identified, and how similar species were eliminated is also helpful. Other useful information you might report includes optics used, distance from bird, lighting or weather conditions, length of time viewed, and other observers present.

Male BLACKPOLL WARBLER (Santee Lakes / May 7, 2018)

Took a late afternoon lap around Santee Lakes today (Mon, May 7, 2018). 

The big highlight was a shocker adult male BLACKPOLL WARBLER which surprised at point black range along the east edge of Lake 4 (near the middle of the lake by the small bridge/dock) while I was perusing the multiple blooming silk oaks for migrants. It spent most of its time low in the small live oaks by the fence line but also hopped up into the silk oaks. 
 
This is my first ever sighting of an adult male, having only seen dull female types in fall previously. Initially I almost passed it off as a Black-throated Gray as the bird was partially obscured but I was struck by the super short tail, then it emerged into full view and I realized what I had!
EBird checklist with a low res docushot I was able to snap with my phone when it hopped onto the fence about 5ft away from me:

Re: Unusual kestral nesting site?

Paula, 

I first noticed kestrels nesting in these marker balls about 8 years ago, but this nesting behavior is noted in the Bird Atlas so it had been going on for quite some time previous to that. 
I’m very curious to know about the success rate of breeding attempts in these marker balls. They must get really hot, they swing around in the wind, and they are usually 200’ or so in the air so that first flight better go well! At least snakes aren’t
going to be a concern.

Orioles

just had what looked like a juveile orchard oriole fighting over my water with a hooded, darker back and smaller black spot on throat is what caught my attention. Fallowed the bird with the bins and caught a groupd of about eight orioles in a euc. One looks like a adult male baltimore…might be a orchard…but both are lifers for me so I need confirmation.

If your in the area, I’m looking at it now.

Re: Green Jay, best spot for Western Tanagers

Sue et al.,

I copy the email I wrote regarding the American Flamingo below and treatment by eBird reviewers of presumed escapees, and it's the same situation for the Green Jay.
All records submitted to eBird remain in the eBird database unless removed by the observer. Reviewers can only effectively hide them from public output, we do not removed anything, much in the same way that rarities without sufficient documentation are hidden (they still count on that observers list, should they stay the course, but the reviewers don't feel the evidence justifies the claim). Non-natives, whether established or not, remain in the eBird database, they just don't all show up in public output. There is a specific list of species that eBird HQ requests regional reviewers follow for invalidating (hiding) or validating (allowing to appear on maps and bar charts). 

The list of species we eBird reviewers accept is available here:
http://help.ebird.org/customer/portal/articles/1822748-ebird-review-standards

towards the bottom, click "Filter_taxa_recommendations_19Jan2016_CA.xlsx" 

Things like Pin-tailed Whydah and Red-masked Parakeet, which may be established/establishing at locals levels, but don't yet fit the criteria for inclusion on the California state list, are validated in eBird. One-off, obvious escapees, regardless of how long they stick around, like, well, any flamingo in California, Burrowing Parakeet, or Gray-crowned Crane, are invalidated [or in this case Green Jay]. Somewhere in the middle of that spectrum are things like Mandarin Duck and European Goldfinch which probably aren't close to establishment, but show up with enough frequency that they are worth keeping more public tabs on, and are therefore validated.

Of course, as more birders are introduced to birding and listing through eBird, what is acceptable in eBird and what people choose to enter in eBird vs. what is actually on the official state list for California or the ABA Area, leads to apples-to-orange Top 100 listing games (some will enter the [Green Jay] in San Diego into eBird and some won't). However, I'm told this is on a long list of improvements that eBird is working on to make it more apples-to-apples for the Top 100.

Unusual kestral nesting site?

As I drove to Buddy Todd Park this morning, I was stuck in slow moving traffic on westbound 76 near where electrical lines stretch over all lanes. There are large balls on the lines because of the airport. I saw a kestral go into the orange ball over my head. Starlings nest in traffic poles over roads sometime but has anyone heard of a nesting site like this? I guess cavity nesters are having problems finding good sites.


Buddy Todd still had some migrants and a red-breasted nuthatch that I thought would be gone by now. The only new migrant was a western wood peewee near the tennis courts.
