Tell me, small fry, have you ever heard of the golden Triumph Forks? They're there, on that island... Or, at least, a chart leading to them is there. Where's it hidden, you ask? Well, for that answer you'll have to ask a gull.
Bird's Peak Rock
That place is famous for the many birds that live there. Aryll would like it. She was always surrounded by seagulls, wasn't she?
Bird's Peak Rock is named after the large number of Kargarocs and seagulls that nest at its peaks, it is comprised of two parts. The first is a small grassy area with a secret cave on it. The second island is impossible to walk on, but there are switches on the nests on its peaks. By using a Hyoi Pear to control a seagull, the seagull can hit the switches, allowing Link to receive a chart to one of the Triforce Shards.
A Blue ChuChu can also be found on the smaller of the two islands.
