I was sitting in my car next to a frozen river when i suddenly heard a spine tingling screaming coming from about 200m further down. At first i thought it was just a dog walker falling through the ice but it turned out to be a huge rat fighting for its life. A Grey Heron had caught it by its tail and brought it out on to the ice. However, the monster rat wasn't going inside the heron without a fight. The screaming rat was trying to bite the herons legs and was even pulling it along the ice at one point. Eventually the rat broke free and scurried back to some sedges leaving the heron a bit confused on the ice.
