Compiled by: Brooke Miller. Please email additions, corrections, or comments to Brooke at idbirds@me.com. Monthly reports are made up of eBird sightings, postings on South Bay Birds, and direct email reports.

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 2024 with 160 countable birds seen on January 1, and a total of 214 countable birds for the month of January. The average for January 1st is 157, and the average for the month of January is 202. There were 3 birds that were not ABA-countable in January (see below). 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 214 birds that were recorded for January, there were 4 birds rated as rarity (6), and 8 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.
