Across - A poem about a bird

Flight of a hawk,
All she can do is gawk,
At the fiery island,
Of fire and wood.
Across the sea,
Across the sea,
The hawk is wild and free.
To the island of the Gems,
Once thriving,
Now barely surviving,
The island of the Ghosts.
To the west,
To the west,
Where there are the rest,
Reefs and drakes,
Grass and lakes,
Forests and cities,
Lions and kitties.
To the north,
To the north,
Still looking for the fourth,
A budgie,
A cockatiel,
A lion,
Oh, where, where is the fourth?
To the south,
To the south,
Into the forest's leafy mouth,
He is gone,
He has fought,
His last battle,
He is no more...
