Good day all South Bay Birders,
The first-of-the-year Black-headed Grosbeak was seen on 2025-02-28 by Janna
Pauser at Belgatos Park, not as I previously reported on 2025-03-26. That
has been updated in the record.
In April we added 17 new countable birds, bringing the total to 247 at the
end of the month. The average for April is 20 new birds, and an average of
244 at the end of the month. Thank you to everyone who birded, and took
the time to report birds either on SBB, eBird, or send emails directly to
me.

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.
Do not disclose information that identifies the location of nesting birds of any species, to minimize stress on the nesting birds and the risk of vandalism or abuse.
