Yes! I saw and heard two male Antillean Nighthawks calling and display diving at the Marathon Airport. This is a personal triumph. Not just a life bird, but heard first with my Sennheiser Mic and headset than seen. Anybody who has poor hearing like me can appreciate the satisfaction when you do hear a calling bird.
I stopped at the Tavernier Winne Dixie, but felt it was too noisy. So i drove the additional 30 miles and set up at the aiport in Marathon, a known nesting sight for Antillean Nighthawks. Larry Manfredi suggested driving to the south end and sitting at a picnic table, but heard nothing. It then dawned on me that Larry has exceptional hearing. So i drove back a 1/4 mile towards the terminal and bingo!!
Tomorrow morning is the pelagic trip.
