Observation details
Apparent second prebasic black and white booby (fresh inner primaries and outers still in midst of being replaced) that made close approaches to the boat. Heard to also utter a couple of nasal squawks (attached along with iphone video). Bill color was dull at the base (multiple photos show general horn color but with some gray on top of upper mandible) but importantly a warmer golden tone along the distal half of the bill and towards the bill tip. Appears to be a very close match in color and tone to example F on p136 of Pyle https://www.birdpop.org/docs/pubs/Pyle_2020_Molt_Age_and_ID_of_MABO_and_NABO.pdf White on central retrices bled towards tip and I would score this a 3 or 4 and would also appear to lend support to Nazca as the ID.
