The week in wildlife

The critically endangered araripe manakin ( Antilophia bokermanni ), which is declining due to ongoing habitat clearance for agriculture within its tiny range in Brazil. The world has failed to meet the target set by international leaders to reduce the rate of biodiversity loss by this year, experts will announce next month Photograph: Andy & Gill Swash/worldwildlifeimages.com Photograph: Andy & Gill Swash/guardian.co.uk A squirrel scratches itself on a tree in a forest of Vaasa, Finland Photograph: Olivier Morin/AFP/Getty Images Photograph: Olivier Morin/guardian.co.uk To mark the first Full Bloom festival, we asked you to help us celebrate the beauty and biodiversity of spring blossom by posting your images on our Flickr group.

Dozens of orchards have been planted, restored and surveyed in the first year of a project to protect traditional fruit trees and their habitat , the National Trust said. Traditional orchards, which are home to local fruit varieties and provide an important habitat for wildlife, are now listed as a conservation priority under the UK biodiversity action plan. The project aims to reverse the decline in traditional orchards which has seen more than 60% of sites disappear since the 1950s. The classic feature of the British countryside has declined as a result of development, conversion to other uses and pressure on small-scale producers from commercial fruit growing Photograph: Matt Smith/NTPL/PA Photograph: Matt Smith/NTPL/guardian.co.uk A frog hides among lily pads in a pond in Roswell, New Mexico. Today marks the second annual Save the Frogs day , which aims to raise awareness of the conservation issues threatening amphibians worldwide. Amphibians (frogs and toads, newts, caecilians and salamanders) are being affected by habitat loss, climate change, pollution, pesticides and introduced species, but face an even bigger threat from a deadly parasitic fungus known as amphibian chytrid.

Research published in the journal Current Biology has examined how chimpanzees deal with death. Video footage shows a young chimpanzee playing with the mummified corpse of an infant group-mate, before the dead chimpanzee's mother retrieves it. Lead author Dora Biro said: 'Our observations showed a remarkable response by chimpanzee mothers to the death of their infants: they continued to carry the corpses for weeks, even months, following death.'

The micro moth, whose wingspan is just 6mm, was discovered in Hembury Woods in Devon by local naturalist Bob Heckford who noticed tell-tale signs of mines dug through the leaves of oak saplings. The new species has not been found anywhere else in the world and has been named Ectoedemia heckfordi after Heckford Photograph: Handout/PA Photograph: Handout/guardian.co.uk An oak forest in Hembury Woods, Devon.

The tiger was found straying by officials during a recent storm and released back into the wild. According to the most recent Indian government census there are only roughly 1,400 tigers left in the country. This week the country announced its intention to severely limit tiger tourism Photograph: Joydip Suchandra Kundu/AP Photograph: Joydip Suchandra Kundu/guardian.co.uk A starfish washed ashore on the Chandeleur Islands, off the south-eastern coast of Louisiana.
