These are called
boars where I live

Boars live now in the outskirts of urban areas of Poland. Imagine my surprise on my night ride over a popular road in the county capital city; when I was about to leave the road for a bike path in the meadow, I could notice a gray animal of the size of a big dog under a bush. As the beast squealed at me, I realized it was a boar, and screamed out of fear! You can imagine how fast I started spinning my cranks to get myself in a safer area!
Because, as a children song taught us:
"Who meets a boar in the forest
Quickly finds a safety on a high tree branch!"
Honestly, I would be afraid to get in a collision with a deer or a roe-deer on a ride in our large National Park nearby, and we have many beasts living there! I could see those animals crossing my path at high speed often! (The moose is the symbol of the Kampinos National Park. I could spot a moose only once from my car; the beast was stopped by a roadside fence and got in panic -- it was a scary view!)

Warning signs (the first one is to protect the reptiles) in the KPN. The warning signs related to the moose happen there frequently, too. But the cows?
