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.

Eurasian Red Squirrel (Sciurus vulgaris)


The red squirrel is the only known rodent that hosts leprosy and in fact, it’s thought the Vikings spread the disease to the UK by transporting squirrel pelts.

Pine Marten:

Although these mustelids are predators of the red squirrel, they are also helping them. Introduced gray squirrels carry a pox they are immune to, but kill the reds. Where martens live & prey on grays, the reds rebound.

Scots Pine:

This tree is a particular favorite of red squirrels and they are often found where these trees grow. They eat the seeds and also nest in the trees.


The red squirrel is iconic for their ear tufts. But these are part of their winter wardrobe and they actually lose them during the summer months only to regrow them again for the winter.
