A bull with blood on its horn stands alone in a pen during the “Apartado” event, where bulls are sorted before the afternoon bullfight, during Sanfermines in Pamplona, Spain, July 8, 2023. The famed bull-running festival engulfs downtown Pamplona every July when revellers from around the globe descend upon the northern Spanish city for nine days of adrenaline, sweat and debauchery savoured as freely as the wine flows. Some are drawn to the Sanfermines - as the festival is popularly known - by the timeless prose of Ernest Hemingway who became besotted with the Sanfermines on his first visit, exactly 100 years ago. The bull-running, the bullfighting local experts - and the hedonistic partying - captivated him so deeply that he returned eight times between 1924 and 1959.

Emily Roskam and Sarah Woodmartin, both PhD Walsh Scholars at Teagasc, shepherd sheep out of a holding pen towards the methane measuring chambers towards the end of a Seasolutions trial where sheep were fed an extract of seaweed to reduce their methane emissions at the Teagasc Agriculture and Food Development Authority sheep research centre in Athenry, Ireland, September 6, 2021. "We have 140 sheep here and each morning they are getting half a kilo of concentrates, they get 400 grams of nuts made of maize meal and a bit of molasses which is kind of sugary to stick them together, then they each get 100grams of their additives, we have a 'control diet' or we have seaweed extract," said Roskam.

Camels stand behind drying laundry as circus shows remain shut as part of COVID-19 restrictions, at the Royal Circus home base in Senas, France, February 9, 2021. Reuters photographer Eric Gaillard: "When I met William Kerwich in February 2021, his family's travelling circus had not performed a show in nearly a year due to COVID-19 restrictions in France. His morale was low with his family parked on a plot of land in southern France and his lions and tigers confined to their pens. Even if the pandemic ended, he faced another threat to his livelihood: France phasing out the use of wild animals in circuses. His young daughter Cassandra trains the animals and I followed her as she fed the tigers, hippo, horses and camels. During the interview, I noticed some washing hung with tiny garments belonging to a newborn baby, but it didn't make a great photo. Then I got lucky and a group of camels slowly headed toward the clothes line. I waited for the right moment, hoping the camels did not suddenly go in another direction. It worked perfectly and now I always try to include animals in my photos." REUTERS/Eric Gaillard/File Photo SEARCH "POY STORIES 2021" FOR THIS STORY.
