- Reported Jul 12, 2026 09:12 by Reef Comer
- North Pacific Ocean, 35.35579, -121.04882, San Luis Obispo, California

- Checklist: https://ebird.org/checklist/S371468798
- Media: 8 Photos
- Comments: "Update: After reviewing photos, there appears to be a slight pinkish cast to bill favoring Nazca over Masked. Even in these blurry photos, Masked should show a greener-yellow cast to the bill at this age. We were also able to view a second NABO from a similar age class under better viewing conditions and see a similar bill coloration. https://ebird.org/checklist/S371696758

Large booby seen from the bow flying south away from the boat. Unable to definitively ID in the field due to direction of flight."
