Meal times can be a strenuous affair no matter what size your brood is, but spare a thought for the long-tailed tit captured on camera feeding her eleven chicks at the RSPB’s Fairburn Ings nature reserve this week Photograph: Gary Shilton/RSPB Photograph: Gary Shilton/guardian.co.uk An endangered east African black rhinoceros and her young walk in Tanzania's Serengeti national park during the start of an initiative that will see 32 huge beasts flown to Tanzania from South Africa. An explosion in poaching in the 1960 and 70s saw the population of east African black rhinos in Tanzania plummet from over 1,000 to just 70. Seven of the remaining rhinos were relocated to South Africa in an effort to protect them and bring the rhino sub-species back from the brink of extinction Photograph: Staff/Reuters Photograph: Staff/guardian.co.uk A roseate spoonbill passes below a tern over an island in the Barataria Bay on the Gulf coast of Louisiana. The island is home to thousands of brown pelicans, egrets and roseate spoonbills, many of which are now affected by oil after the Deepwater spill .

The sale of wildlife and trafficking of endangered species has been largely ignored by Iraq's government as it has struggled to make the country safer and even though the security situation has improved, it is still not a priority. Conservation groups warn at the same time, however, that the wildlife trade is on the increase as people have fewer concerns about going out shopping and more money to spend Photograph: Maya Alleruzzo/AP Photograph: Maya Alleruzzo/guardian.co.uk Pelicans fly past a nest of eggs on an island off the the coast of Louisiana.
