Geese fight during the annual Geese Fight Day in the northern Serbian village of Mokrin, some 160km (100 miles) from Belgrade February 22, 2015. Every year in the last week of February, goose fights are held in the northern Serbian village of Mokrin. Left alone, male geese, or ganders, are unlikely to fight each other, hence why females are brought along for whose affections the ganders then fight until one or the other gives up.

At just a few months old, two young males and one female gather in a circle, clutch each others' hands and begin to dance to the popular nursery rhyme. It's almost like a scene from a school playground as the bears joyfully play together, tapping their feet and moving around in a circle. (Photo by Valtteri Mulkahainen/Solent News & Photo Agency)

Lily Winter (top) and Lana Austin (back) match up during the “Atomic 6 – Atomic Fighter” wrestling show at the Azvex Brewery in Liverpool, Britain, 21 February 2024. Atomic Pro Wrestling was started in 2023 by wrestling enthusiasts and former training mates Matt Davies, Declan McCarthy (stage name Declan Sands) and Chris Welsh as a way to showcase emerging male and female wrestling talent from England’s North and North West regions, which they felt were being overlooked and under-represented. In contrast to the highly polished world of televised WWE (World Wrestling Entertainment), Atomic takes a DIY approach, holding shows at a local brewery large enough to make way for the ring, and where customers can enjoy craft beer as they watch the wrestling matches from up close.
