Ein Spatz, ein Satz.

One thing that never gets old for Nala is to jumpscare sparrows that are having a chill time at the lake. She loves it when they fly away while cheeping insults at her. Since the lake we visit today is part of a protected landscape we must not disturb nature as we take our walk. Easier said than done with all the sparrows around!

Normal Sudoku rules apply: Place the digits 1-9 in every row, column and box exactly once each.

Additionally the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.

Draw an orthogonally connected looped path around the fenced lake area. The looped path is not allowed to touch itself orthogonally and does not branch. The looped path functions as parity line (even/odd) for the digits on it.

Since there are lots of sparrows scattered everywhere, there will be some unavoidable accidents, but if we see a sparrow in time, the path is not allowed to enter the sparrow cell or any of its 4 orthogonally neighbouring cells because otherwise Nala will charge at them. Successfully dodged sparrows are maximum cells where each of its 4 orthogonally neighbouring cells is smaller than the digit in the sparrow cell.

Some sparrows appeared seemingly out of nowhere and we were way too close once we noticed them coming. Those will unavoidably be charged at. The path, once it has entered into one of the 4 cells surrounding a sparrow, must go into the sparrow cell as well. Attacked sparrows are minimum cells and each of their surrounding 4 orthogonal neighbours have to be higher than the digit in these sparrow cells.

Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all possible dots are given. (There is no negative constraint.)
