January

We started off 2018 with 166 birds seen on January 1, and a total of 200 birds for the month of January. The average for January 1st is 154, and the average for the month of January is 199. 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 200 birds that were recorded for January, there were, 2 birds rated as rarity (6) and 4 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’s:

1. A Pelagic Cormorant was found on 28-January on a levee next to Salt Pond A14 at Don Edwards NWR by Richard Jeffers and Mike Rogers; and

2. The Vermilion Flycatcher, found on 30-December during the Morgan Hill-Calero CBC, was first seen in 2018 on 1-January continuing at the corner of Palm and Laguna in Coyote Valley by multiple observers.

Rarity Code 5’s:

1. Eve Meier was the first person of the year to find the continuing Red-naped Sapsucker on 1-January at Almaden Lake;

2. A Cassin’s Kingbird was found by Bill Pelletier and Kitty O’Neil on 2-January at the Gilroy Water Treatment Plant;

3. On 2-January Larry Spivak found the, continuing from 2017, Evening Grosbeak in downtown Los Altos; and

4. A Swamp Sparrow was seen by James Brooks and Will Brooks on 13-January at the Palo Alto Baylands across from the airport runway.

I have now revised the list of birds to conform to the taxonomic changes adopted by the AOS (American Ornithological Society) in 2017.

The Oakland Zoo website says they are “near threatened” in the wild, that listing by IUCN. They are endemic to North-central Tanzania.
