ルール
puzz.linkより
1. 親鳥（○、白丸）と雛鳥（●、黒丸）を巣（２マスの灰色マス）まで移動させましょう。
2. それぞれの巣には親鳥と雛鳥が１匹ずつ入るようにします。
3. 親鳥、雛鳥の移動は矢印で表します。矢印の線はマスの中央を通るようにタテヨコに引き、枝分かれさせたり交差させたり他の丸を飛び越えて移動してはいけません。
4. 親鳥はエサを求めて最低でも１回は太線をまたいで移動しないといけません。
5. 雛鳥はまだ飛べないので太線で区切られた仕切りの中でしか移動できません。
原文（上記URLのNo.10より）を編集している。変更点は以下
1. 親鳥（○）と雛鳥（●）→親鳥（○、白丸）と雛鳥（●、黒丸）
4. 最低でも１回は仕切りを→最低でも１回は太線を
(3.の誤字の訂正）
