Singing Crickets are one of the many collectibles in Ghost of Tsushima — and, unfortunately, they are not marked on the map.
Crickets can be found in small cages in the various graveyards of the game.
They're quite easy to find as their song is quite recognizable, but you can equip the Traveler's Attire (given to you for free by talking to merchants) to help you find them.
Not only will the controller vibrate, but you can also activate a special wind to guide you to them when this armor is equipped. None of the crickets can be missed during the adventure, and you can go after them after defeating the last boss if you wish.
