In what is possibly Reddit's most famous subreddit-naming gag, this subreddit is not at all about football. Instead, it's all about a certain order of feathered, nocturnal hunters. What subreddit am I?

The cattle moo, the sheep all bleat, beneath my roof they rest and sleep. Filled with hay from floor to beam, I keep them safe through snow and sleet.

I pull the blanket over the shore, Then strip it back to reveal the floor. I have no voice, yet I roar and sigh, Chasing a master high in the sky. I rise and fall, but I do not stand, Conquering and fleeing the helpless sand.

In epic battles between monkey and lizard these scientists are just amazed. Which organization do they work for?

Substrate for sidewinding snakes. Singular, small. Seen in searing seas and on sea shores. Sometimes shocked, spawning shards, slag and slabs. Specks still in shoes since summertime solace. Smooths certain spots.
