Normal Sudoku rules apply.

DUTCH WHISPERS- Numbers on yellow lines (birds' bodies) are at least 4 apart from their neighbors on the line. Numbers may repeat on the yellow line, if other rules allow.

RENBAN- Numbers on brown lines (birds' wings) are each a set of non-repeating, consecutive numbers, in any order.

RATIO LINES- Numbers on blue lines (birds beaks and legs) are in a ratio of 2:1 with their neighbors on the line.

KILLER- Numbers in cages each sum to ten (10).

KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. The two white dots are the doves eyes, and have no effect on the puzzle.
