This week in birds - #535

 A roundup of the week's news of birds and the environment:

A favorite winter visitor - the Chipping Sparrow.

*~*~*~*

Our ancestors were very hairy creatures and we still carry with us those genes for hairiness, so why don't we look like Australopithecus afarensis?

        Depiction of Australopithecus afarensis. 

*~*~*~*

Seven states rely on the shrinking Colorado River for water. Since they seem unable to come to an agreement for sharing the water, it seems that the federal government may have to impose such an agreement

*~*~*~*

Prescribed burns, a long-time Indigenous practice, can help to restore depleted lands. 

*~*~*~*

Inuit communities are calling for mandatory measures to reduce underwater noise pollution which they blame for the disappearance of narwhals and ringed seals from areas where they used to hunt them.

*~*~*~*

Why do the newts cross the road and why are there volunteers out there helping them to do it?

*~*~*~*

When scientists tagged a southern elephant seal in 2011, they could little have guessed the important information that would be provided by that tag.

*~*~*~*

This is the American Bird Conservancy's Bird of the Week, the Sharp-tailed Grouse and it is one tough customer!

*~*~*~*

The federal government has banned roads and logging in Alaska's Tongass National Forest, restricting development on more than nine million acres of the continent's largest temperate rainforest.

*~*~*~*

Did you know that freshwater stingrays exist? Well, they do exist in the Amazon and they have just received some much-needed protection.

*~*~*~*

A 600-square-mile iceberg has just broken off of the Brunt Ice Shelf in Antarctica. According to scientists, this was a natural event not related to climate change. 

*~*~*~*

New Yorkers have recently been delighted by the sight of common dolphins frolicking in the Bronx River, something that had not occurred for many years because of pollution in the river. Their return is a sign of the improving condition of the waterway.

*~*~*~*

Turf wars between salt marsh microbes dictate how much carbon the salt marshes store and how much methane they release into the atmosphere.

*~*~*~*

Precipitation has been above average in the West this winter but it will not be enough to pull the region out of drought conditions.

*~*~*~*

Seeds held in a seed bank, many of them as old as agriculture itself, may hold the key to our survival from climate change.

*~*~*~*

They are cute and furry and they may just be the key to saving the ecosystem of the West Coast. A non-profit conservation group is hoping to restore the sea otter all along the coast to help bring back its decimated kelp forests.

  1. Good morning, Dorothy, and thank you for the roundup. I am delighted to see the picture of the Sea Otters at the end of the post. They are creatures that have given me great pleasure on several visits to the west coast and I rejoice in the fact that they have survived near extinction due to exploitation for their fur. Now if only we could resolve to stop polluting their home.....

  2. I'm surprised that the rain in the West is not enough to pull the region out of drought conditions.

    Keeping Alaska's Tongass National Forest free of roads and logging is something I wish would happen more often.

    Thank you for sharing news from nature! I look forward to reading your summary each week.

  3. Since Arizona has experienced drought for twenty years that I know of, it comes as no surprise to me that this wet winter isn't enough to pull us out of it. I would imagine that the major thing that's keeping Colorado River water states (like Arizona) from coming to any sort of agreement is MONEY. They want to continue to encourage tourism and people moving in and on and on and on--- but what rabbits are they going to pull out of their hats when the water runs out? No one wants to believe that the drought will never end when that scenario is something that should have been planned for long ago.
