A mother and baby humpback whale in Kiama, New South Wales, Australia. Humpback whales give birth while migrating – and carry on travelling with their babies, new research reveals. Researchers were puzzled as baby whales were spotted in unexpected places along Australia’s “humpback highway” between Queensland and Antarctica. Newborns have been seen in colder waters as far south as Tasmania, suggesting humpbacks’ habits of breeding and migration are more complex than we thought

A mother mute swan attends to her cygnets at Abbotsbury Swannery, Dorset, UK. The arrival of mute swan cygnets is traditionally seen as the start of summer, and it’s said the Benedictine monks who owned the swannery between about 1000 and the 1540s believed the first cygnet signalled the season’s first day

A lion sits in a cage waiting to be transported to Mazatlan on Mexico’s west coast. Hundreds of animals including elephants, crocodiles, lions and tigers have been moved out of a violence-torn Mexican cartel heartland further north in an operation described as a “21st-century Noah’s Ark”. Regular roadblocks and armed clashes in the region made it difficult for the sanctuary’s workers to keep the captive wildlife fed. In total, about 700 animals were moved to a ranch on the coast

Video footage shows a baby howler monkey clinging onto a young adult male capuchin monkey on Jicarón Island, Panama. Scientists have spotted surprising evidence of what they describe as monkey kidnappings while reviewing video footage from the small island. Capuchin monkeys were seen carrying at least 11 howler babies between 2022 and 2023 – but no one is sure why they do it

A group of Orinoco crocodile hatchlings are released into the wild at the Capanaparo River, in a remote corner of Venezuela. For decades, the Crocodile Specialist Group have been raising younglings of the critically endangered species in captivity in a race against time to avoid its extinction, as fewer than 100 Orinoco crocodiles remain in the wild. Decades of poaching for leather has pushed the species to the brink, and now struggling Venezuelans who hunt the animals for meat and take their eggs for food threaten to deal the final blow

Honeybees return to their hive in Wehrheim near Frankfurt, Germany. Plants can “hear” bees buzzing and serve up more nectar when they are nearby, scientists have found. Amazingly, they can tell the difference between a bee’s buzz and that of a non-pollinating insect such as a wasp
