Roost: Owl Logic Puzzle

Roost is a calm owl puzzle - pure logic, no guessing. Every board is a wood divided into colourful territories. Exactly one owl roosts in each row, each column and each colour region - and no two owls ever sit next to each other, not even diagonally. Rule out the cells that cannot work, and the owls reveal themselves. Every puzzle is solvable by deduction alone. No time limit, no luck, no dead ends.

Roost belongs to the family of one-per-row placement puzzles, sometimes called star battle puzzles, with owls in place of stars. Grids start at 5x5, so the rules click quickly, then grow to 8x8 as your deductions get sharper. It's a brain teaser for anyone who likes sudoku-style logic without the arithmetic.
