What is Street Creatures?  This is the game I run on Twitter every Friday. I’ve
collected all the past quizzes here in one place so you can either relive them, or play
them for the first time.

How does it work?  Provided are four, seemingly unrelated clues, that are all
connected by a wild organism that can be found in a city. Look at the four clues,
do some research, and when you think you’ve figured it out, click on ‘Answer’
to reveal what connects the clues, and how they are connected.

Follow me on Twitter to play #StreetCreatures live every Friday at 9am PST.

Quiz #10 Clues

Carl Linnaeus
Trap-Tube Problem

Answer (Don't click until you've solved it)

Rook (Corvus frugilegus)


Act 3, Scene 4:

“It will have blood, they say. Blood will have blood.
Stones have been known to move, and trees to speak.
Augurs and understood relations have
By magot pies and choughs and rooks brought forth
The secret’st man of blood.—What is the night?”


She was a figure from Irish mythology associated with war and death. She also had the ability to transform into a crow, raven or rook.

Carl Linnaeus:

Linnaeus gave the rook its binomial name, Corvus frugilegus.

Trap-Tube Problem:
