Observation details

In both counties! Found right at the county line. Year old bird, starting molt of P1, and central tail feathers. Identified as Nazca due to dark hindeck, lacking white collar. Also head browner than expected on similar age Masked Booby. Dark on underwing as expected on Nazca Booby. Also bill with dull dusky base, and bright yellowish tip. Slight pinkish blush on bill was present. Second record for San Mateo?
