The week in wildlife

Oil-stained cattle egrets walk on the deck of a supply vessel at the site of the Deepwater Horizon oil spill in the Gulf of Mexico, off the coast of Louisiana Photograph: Gerald Herbert/AP Photograph: Gerald Herbert/guardian.co.uk This image of a sea hare, taken by Robert Bailey, was highly commended in this year's British Society of Underwater Photographers awards, an annual print competition that is part-judged by The Wildlife Trusts . Photographers are urged to capture the essence of ‘living seas’ – the colourful, diverse and often surprising wildlife and habitats found around UK coasts. • Click here for a gallery of all the winning images Photograph: Robert Bailey/The Wildlife Trusts Photograph: Robert Bailey/guardian.co.uk A rare species of solitary bee found in the Middle East, Osmia avosetta , constructs its nests from petals and mud, creating chambers of pink, yellow, blue, and purple for its larvae. The colorful nests make moist, secure chambers for the larvae to grow, feast on nectar and pollen laid by its parents, and build a cocoon to wait out the winter. This behaviour was discovered on the same day by teams in Turkey and Iran, where the insects are mostly found Photograph: J.G. Rozen/AMNH Photograph: J.G.

In the wild, these monkeys are found in Central and South America, but are threatened due to habitat destruction, hunting and live capture for pets Photograph: Itsuo Inouye/AP Photograph: Itsuo Inouye/guardian.co.uk A buck eats grass in a field near Medvode, Slovenia Photograph: Srdjan Zivulovic/Reuters Photograph: Srdjan Zivulovic/guardian.co.uk A honeybee collects nectar and pollen from a fully grown sunflower in a field near the city of Amritsar, northern India Photograph: Raminder Pal Singh/EPA Photograph: Raminder Pal Singh/guardian.co.uk A cloud forest habitat in southern Peru. Cloud forests are a rare type of evergreen mountain forest found in the tropics where the local climate causes cloud and mist to come into regular contact with the forest vegetation. These forests are very important as they support distinct ecosystems and contain a disproportionately large number of the world’s endemic and threatened species Photograph: Ignacio De la Riva Photograph: guardian.co.uk An iguana at Bolivar park in Guayaquil, Ecuador Photograph: Guillermo Granja/Reuters Photograph: Guillermo Granja/guardian.co.uk An osprey carries a fish in Cape Canaveral, Florida Photograph: DON EMMERT/AFP/Getty Images Photograph: DON EMMERT/guardian.co.uk A crab sits on the shoreline on the beach on Dauphin Island, Alabama, one day after tar balls from the Deepwater Horizon oil spill washed up onshore. The spill — a slick more than 130 miles long and 70 miles wide — threatens hundreds of species of wildlife, including birds, dolphins, and the fish, shrimp, oysters and crabs that make the Gulf Coast one of the nation's most abundant sources of seafood Photograph: Brian Snyder/Reuters Photograph: Brian Snyder/guardian.co.uk The eye of a giant oarfish. A maritime expert says this 12-foot (3.65m) specimen - the world's largest bony fish - has been found in Swedish waters for the first time in 130 years. Also known as the 'king of herrings', the dead fish was picked up by a west coast resident who found it floating near the shore Photograph: Roger Jansson/AFP/Getty Images Photograph: Roger Jansson/guardian.co.uk Turtle weed ( Chlorodesmis fastigiata ) growing on a coral reef. Scientists found this week that this seaweed, along with several other common species in both the Pacific Ocean and the Caribbean, can kill corals upon contact by releasing deadly chemicals Photograph: Georgia Tech Photo/PA Photograph: Georgia Tech Photo/guardian.co.uk Environmentguardian.co.uk is collecting the best photos of water boatmen, beetles, snails, alderflies, frogspawn, damselfly larvae and other pond wildlife.

The million-acre park celebrates its 100-year this week. The glaciers are currently being studied to measure the effects of climate change. It is estimated that if current warming trends continue, there will be no glaciers left in the park by 2020 Photograph: Michael Albans/AP Photograph: Michael Albans/guardian.co.uk An oil-soaked cormorant struggles against the side a supply vessel at the site of the Deepwater Horizon spill in the Gulf of Mexico. Oil sticks to birds' feathers, damaging the 'waterproofing' and buoyancy and exposing them to hypothermia. Birds also try to clean to oil off their feathers, which results in the animal ingesting the oil and damaging its internal organs. Apart from oil spills, millions of water birds die every year due to oil from from jet skis and motorboats, and waste oil that is washed off streets and into storm drains after rain Photograph: Gerald Herbert/AP Photograph: Gerald Herbert/guardian.co.uk
