In many works, wolves are heard howling at dusk or at night. It is a case of NoisyNature. Also, it is often a case of not doing the research or ArtisticLicense: wolves don't live in all settings, and they usually howl to communicate with each other, not to establish the mood or tell time. Often overlaps with CockADoodleDawn, which is when roosters crow at dawn.

This trope has two main types:

'''Type A:''' Wolf howls are heard to herald the coming of the night. The wolves that do the howling are rarely seen.

'''Type B:''' The howls are heard late at night, to reinforce a creepy setting or establish a fearful mood. Again, the wolves are rarely seen.

See also WolvesAlwaysHowlAtTheMoon and HowlOfSorrow. Related to CockADoodleDawn.

!Examples:

!!Type A: At Dusk Version:
!!!Video Games:
* Occurs in three installments of the ''Zelda'' series. Wolves howl whenever night falls.
** ''VideoGame/TheLegendOfZeldaOcarinaOfTime''
** ''VideoGame/TheLegendOfZeldaMajorasMask''
** ''VideoGame/TheLegendOfZeldaTwilightPrincess''
*** Also, when unlocking the howling stones, no matter what time you do the first minigame, you are transported to another area where it is always night to do the second howling minigame.
* Happens in ''VideoGame/{{Okami}}''.
* ''VideoGame/WarcraftIII'' has a wolf howl to tell the player that night has fallen (and a rooster crowing to indicate daybreak).
* When you visit Garoh in ''VideoGame/GoldenSun 2'' for the first time (at night), mournful wolf howls are heard [[spoiler:(because it's a village of werewolves)]]. Sadly, [[CrowningMusicOfAwesome the version of the BGM with howls]] is not part of the soundtrack.
** Though the version without the howls is [[CrowningMusicOfAwesome a darned fine song in its own right.]]

!!Type B: Late at Night Version:
!!!Anime / Manga:
* Holo from ''SpiceAndWolf'' does this on occasion, even when in human form.
