South Bay Birders,
In September we added 5 new (ABA) countable birds, bringing the total to
271 at the end of the month. The average for September is 10 new birds,
with an average of 276 at the end of the month. We also had one (ABA)
uncountable bird – a Mute Swan, seen by Mike Rogers on 25-September in Salt
Pond A18. Thank you to everyone who birded, and took the time to report
birds either on SBB, eBird, or send emails directly to me.
Here are the (ABA) countable birds that were found in September:
1. Ruff (5), 2025-09-07, found by multiple observers, along the Don Edwards
NWR entrance road
2. Summer Tanager (5), 2025-09-10, found by John Scharpen at Sanborn County
Park – main entrance
3. Dark-sided Flycatcher (6), 2025-09-17, a first seen for the lower 48
states, found by Eve Meier and Patricia Lynch, at Charleston Road Marsh
4. Rose-breasted Grosbeak (5), 2025-09-02, first found by Ken Mamitsuka, at
Ulistac Natural Area
5. Pectoral Sandpiper (4), 2025-09-26, found by Cliff Drowley along the Don
Edwards NWR entrance road
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.
