The logbook states that the fleet left the west port of
Mazaua early morning of Thursday, April 4, 1521. According to Pigafetta, they took a northwest track, however Albo claims they took at northern track. The ships sailed to reach Gatighan at 10° N in 11–13 hours. During the brief stop on the island, Pigafetta documented the island's fauna: "
In this island of Gatighan are a kind of birds called Barbastigly (flying fox), who are as large as eagles. Of which we killed a single one, because it was late, which we ate, and it had the taste of a fowl. There are also in that island pigeons, doves, turtledoves, parrots, and certain black birds as large as a fowl, with a long tail. They lay eggs as large as those of a goose, which they bury a good cubit deep under the sand in the sun, and so they are hatched by the great heat made by the warm sand. And when those birds are hatched they emerge. And those eggs are good to eat." On Pigafetta's map, Gatighan is the only island mass that straddles between two huge islands,
Bohol and
Ceylon/Seilani (Panaon Island, the south most end of Leyte). It is almost exactly at the 10° N latitude, reference point of Albo for Gatighan. ==Attempts to locate the island==
