Please post all your sightings at southbaybirds@groups.io 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

January

We started off 2020 with 170 countable birds seen on January 1, and a total of 208 countable birds for the month of January. The average for January 1st is 155, and the average for the month of January is 200. This year I am also keeping track, separately, of the birds that are not ABA-countable. There were 3 such birds in January. 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 countable 208 birds that were recorded for January, there were 2 birds rated as rarity (6) and 9 birds rated as rarity (5). As a reminder, here is what each rarity code means:

Rarity Codes**

1 = common, always seen in habitat in season.
2 = fairly common, usually in habitat in season, but missed sometimes.
3 = uncommon, always around, but sometimes you can't find.
4 = rare, occurs yearly in the county, but not always in same places.
5 = very rare, does not occur every year.
6 = casual or vagrant, generally fewer than 10 records.

Rarity Code 6:

  1. Tropical Kingbird, 1/1/2020, Near the End of Embarcadero Road, by Bill Bousman

  2. Lesser Black-backed Gull, 1/11/2020, Salt Pond A16, Don Edwards NWR, by Steve Rottenborn

Rarity Code 5’s:

  1. Evening Grosbeak, 1/1/2020, Downtown Los Altos, by Multiple Observers

  2. Red Crossbill, 1/1/2020, Sanborn County Park, Skyline Trail, by Steve Tucker

  3. Yellow-headed Blackbird, 1/1/2020, between Salt Pond A4 and Twin Creeks Complex, by Brooke Miller

  4. Yellow-bellied Sapsucker, 1/2/2020, Santa Clara Valley Water District Headquarters, by Janna Pauser

  8. Red-naped Sapsucker, 1/26/2020, Guadalupe Creek Trail near Guadalupe Mines Rd, by Mike Mammoser

  9. Black Rail, Sensitive Species - so date, location, and observer/s are hidden from output

    Starting 1-January, eBird has classified Black Rail as a ‘Sensitive Species’ in the County, and therefore specific date, location, and observer/s are hidden from output. I have arbitrarily used the last day of the month in my reports and records.

The 3 ABA non-countable birds for January were:

  1. Mitred Parakeet, 1/1/2020, Las Palmas Park, by Eve Meier and Patricia Lynch

  2. Red-masked Parakeet, 1/2/2020, Las Palmas Park, by Gena and Jeff Zolotar

  3. Scaly-breasted Munia, 1/7/2020, Yard at the base of Coyote Ridge near 101/85, by Craige Edgerton

My monthly reports are made up of eBird sightings, postings on SBB, and direct emails.
