- Comments: "rare here no matter when and then a somewhat late sighting, and instead of a single or two bird grouping-three; with sun above and slightly right and behind me for good clear viewing-watched several swifts fly by that were large (bigger than WTSW), all dark (no white on throat or elsewhere-I looked hard for any white as I knew this ruling out was crucial to i.d.), notched tail on 1 bird and fanned w/ square tail on the other two. tail projected past wings farther than head/neck projected forward and wings were wider than a VASW and flight was less "fluttery" with some gliding between wingbeats. watched birds come, fly right in front of me, and passed me heading southward. waited for 10 more minutes to see if they would return-no."

Using my car door as a blind I was able to get several photos over the next 5 minutes before it flew off, heading out over the creek to the west. It circled about and returning in less than 5 minutes, this time settling on the sycamore snag. Descriptions of this rarity included in several of my posts and those of many other birders."

Neotropic Cormorant (Nannopterum brasilianum) (1)
- Reported Jun 16, 2025 08:00 by Jim Royer
- Morro Creek mouth, San Luis Obispo, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&<q...>,-120.8624411&<ll...>,-120.8624411
- Checklist: https://ebird.org/checklist/S251266464
- Comments: "A continuing bird found by Tom Edell. It was a cormorant with a smaller head and bill than a Double-Crested, with yellow on the throat base of bill area but no yellow in dark lores and a light border to the back of the yellow throat patch. Like a Double-crested it flew with a bend in the neck (head held higher than the neck). It appeared to be a juvenile, but it had a dark chest rather than the light colored chest of a Double-crested. I observed it fly into the sycamore tree to roost, fly down to the creek to catch fish, and spread out to dry its wings elevated above the creek on a concrete chunk."
