Barely does its justice to the number of birds calling at once but luckily still managed to capture the calling birds that were closer to our boat.

**High count. Discussed this number at length and 200 was the minimum number that we could settle with. Very likely a gross underestimate. Got woken up just around midnight to a mass of calling Leach’s Storm-Petrels literally swarming around the boat. Managed to obtain some audio recordings, with a less-than-ideal iPhone microphone, which have been compiled in a sound clip and attached to this checklist. Lots of boat and wave action drowning out the more distant calling birds. It wasn’t long before several Leach’s began bumping into our outriggers and satellite antennas and sure enough two individuals landed in the boat. Luckily we were awake and viewing this stunning spectacle and managed to help these birds back to sea. Equipped with high powered LED flashlights we were able to scan 360º around the boat to roughly 100 yards out. Everywhere we looked were bounding Leach’s easily separated by the fewer numbers of Wilson’s Storm-Petrels by their distinctive larger size, long-winged appearance and more buoyant, bounding and purposeful flight (and the irruption of calling birds as previously noted). It wasn't difficult to count 50 birds in a few quick scans and this checklist runs for 90 minutes. We had a hard time finding Wilson’s in the swarm of Leach’s. There appeared to be a thick mass of krill interspersed with tiny bioluminescent jellyfish stacked thick across the ocean surface which would help explain the high numbers of feeding Leach’s. We found a red oily-like excrement emitted from one of the boat-bound Leach’s which supports a heavy diet of krill. The morning light revealed more of these “droppings” on the deck and roof of the boat. Also potentially noteworthy is that we were in the middle of a new moon phase. We finally decided to try and catch some sleep but the non-stop calling Leach's made for a restless, but exciting night.
