Sula nebouxii
Identification.
Bright blue feet, brown and white shaggy plumage, white underside.
Galápagos context.
Roughly 70% of the world's roughly 40,000 breeding pairs nest in Galapagos.
Encounter context.
Hunts by plunge-diving from up to 80-100ft at around 60mph, sometimes diving 80ft or deeper underwater - skull air sacs cushion the impact.
Seasonality.
Courtship display (the "booby two-step," with males stamping their feet) occurs across the year; foot brightness correlates with health and diet.
