Santa Clara County Bird List Discussion Archive 2016
Compiled by: Brooke Miller. Please email additions, corrections, or comments to Brooke at email@example.com. Monthly reports are made up of eBird sightings, postings on South Bay Birds, and direct email reports.
Please post all your sightings at firstname.lastname@example.org and/or eBird. You can use eBird to follow first-of-the-year sightings. Due to the fact that not everyone uses eBird, not all sightings will be included, however. To see first-of-the-year sightings in eBird do the following:
- Click on "Explore Data" at the top of any eBird page
- Select "Explore a Region"
- Type in "Santa Clara" and wait for the page to fill it in
- Select "Current Year" and click "set"
- Click on "First Seen"

We started off 2016 with 176 birds seen on January 1, and a total of 205 birds for the month of January. The average for January 1st is 153, and the average for the month of January is 198. Thank you to everyone who birded, and took the time to report birds either on SBB, eBird, or send emails directly to me.
Of the 205 birds that were recorded for January, there were 4 birds rated as rarity (6) and 8 birds rated as rarity (5) they are:
Rarity Code 6's:
The Orchard Oriole (6) seen at the end of Embarcadero Way, and the Black-throated Sparrow (6) at Santa Teresa County Park continued from the end of 2015. A Black Oystercatcher (6) was found on the A5/A8 levee on January 29.
Rarity Code 5's:
One of more Red-necked Grebes (5) continued on January 1, on the far end of Calero Reservoir. A Red-naped Sapsucker (5) was found in the area behind the Spring Valley Unit of Ed Levin County Park on January 1. The first Evening Grosbeak (5) of the year was found in downtown Los Altos on January 11.
The year's first reporting of the Yellow-bellied Sapsucker (5) (also known as the 'mystery sapsucker') in the dirt parking lot across from the Spring Valley Unit of Ed Levin County Park, was made on January 15.
On January 17, the Northern Waterthrush (5) was found at Charleston Road Marsh. On January 21 the Swamp Sparrow was found after high tide near the trail that parallels the Palo Alto Airport.

First of all, for January, a Wilson's Warbler banded on January 31 at CCFS was left off the list. So, that increases the January total from 205 to 206. There were 13 new birds found in February, which brings the total, at the end of February, to 219. That is 11 birds over the average for the month, and 54% of all the bird species seen in Santa Clara County.
There were no Rarity Code 6's found in February.

During the month of June, I was made aware of two sightings that had been entered into eBird, but had not been previously included in my reports. These were:
- 20-Jan: Clay-colored Sparrow (5), seen on the Permanente Creek Trail
- 23-Feb: White-winged Scoter (5), seen on Salt Pond A8
That increased the year’s total to 265 before June.
In June there was 1 new bird reported, a Pacific Golden-Plover (5), found on Salt Pond A13 by Mike Rogers, Mike Mammoser, and Richard Jeffers, during a shorebird survey. This brings the total to 266 at the end of June, which is 11 species over the average of 255. We’re still at a record pace, with 4 more birds reported than any year in the past. At the half-year mark we have seen 66% of all the bird species recorded in the County.
July’s average for new birds is 4.
In July there were 2 new birds reported:
- 6 LEAST TERNS (4) at Salt Pond A2E on 24-July; and
- An ELEGANT TERN (4) at Salt Pond A3W on 27-July.
(The number in parentheses is the rarity code for that bird for Santa Clara County.)
This brings the total species to 268 at the end of July, which is 9 species over the average of 259. We are still at a record pace, with 1 more bird reported than any year in the past. We have reported 66% of all the bird species recorded in the County.
August’s average for new birds is 6.
eBird users will notice some changes that occurred in August during the annual taxonomic updates of the eBird/Clements checklist:
- Western Scrub-Jay has been split into 2 species. California Scrub-Jay (our local species) and Woodhouse's Scrub-Jay (Great Basin etc. species). In your eBird lists, our local scrub-jay is now California Scrub-Jay.
- Two formerly separate species, American Coot and Caribbean Coot, have been lumped into one species, American Coot. In eBird, all American Coots in North America are now “American Coot (Red-shielded)” and American Coots in the Caribbean are now “American Coot (White-shielded)”. In your eBird lists you can use either “American Coot” or “American Coot (Red-shielded)” for our local coots.
Pete Dunten, our county’s eBird reviewer, sent me the following, in response to my question about whether eBird would be updating their lists to conform with the recent AOU taxonomic changes: "AOU-NACC implemented some sweeping changes this year with regard to the sequence of orders among the non-passerines, and sequence of families within Passeriformes. We have not followed these changes in the current eBird/Clements Checklist, but we expect to so in our next round of revisions (August 2017)."
In August there were 6 new birds reported.
- 11-Aug: BAIRD’S SANDPIPER (4) at Salt Pond A13;
- 15-Aug: SOLITARY SANDPIPER (5) at Coyote Lake;
- 21-Aug: BAR-TAILED GODWIT (6) at Salt Pond A17;
- 28-Aug: 2 WANDERING TATTLERS (6) on the A10/A11;
- 28-Aug: 2 BLACK TURNSTONES (6) in a closed area of Don Edwards NWR; and
- 28-Aug: PECTORAL SANDPIPER (4) flying over A15.
(The number in parentheses is the rarity code for that bird for Santa Clara County.)
All of August’s new birds were shorebirds and all but one were found at Don Edwards National Wildlife Refuge in Alviso.
This brings the total species to 274 at the end of August, which is 9 species over the average of 265. We are still at a record pace, with 2 more birds reported than any year in the past. We have reported almost 68% of all the bird species recorded in the County.
