Collapse of Avian Biodiversity in the Pacific - MAHB

Collapse of Avian Biodiversity in the Pacific - MAHB | GarryRogers Biosphere News | Scoop.it
We arrived off Ducie Island at dawn on October 12. The rough seas and the air above the low atoll in the Pitcairn group of the South Pacific were alive with birds.

Our last stop was Easter Island, one of the most isolated islands in the world, some 1200 miles east of the Pitcairn group and 2000 miles from South America.  Easter Island is the site of an ecocatastrophe, made famous by Jared Diamond.[4]  All of its native birds are extinct, replaced by a collection of “garbage birds” (ones not sought by bird-watchers), especially the wide-ranging South American Diuca finch pictured here, which flits among the looming stone heads.

The state of the birds on these islands is a harbinger of a catastrophe that looms globally,  
Garry Rogers's insight:

Our leaders could promote nature preservation.  Our college planning departments could recommend zoning and construction changes that would avoid so many animal deaths.  Without leadership and rules, our urban population will remain unconcerned with the fate of wild animals.  Perhaps a few hundred years from now people will have learned to appreciate the species that remain.  For those of us afflicted with biophilia, this is a painful prospect.  Would it be effective to conduct petition campaigns aimed at our planning education and government departments?

350 New Bird Species; More Than 25% Threatened

350 New Bird Species; More Than 25% Threatened | GarryRogers Biosphere News | Scoop.it
From Birdlife
One tenth of bird species flying under the conservation radar
More than 350 newly recognised bird species have been assessed by BirdLife International for the first time on behalf of The IUCN Red List of Threatened Species™.
Garry Rogers's insight:

Perhaps the real surprise is that more aren't threatened.  In my home state, wildlife biologists consider more than half of the 451 native species vulnerable or imperiled, many critically imperiled.

Save this critically endangered bird!

Save this critically endangered bird! | GarryRogers Biosphere News | Scoop.it

Less than 500 are left, but if the government steps up to increase habitat protections we could save them. (23,536 signatures on petition)

Garry Rogers's insight:

This Francolin (Francolinus ochropectus) occupies two small areas in Djibouti in the horn of Africa.  It prefers dense African juniper habitat near the coast of the Gulf of Tadjora in the southern Sea of Aden.  Formerly abundant, the Francolin numbers were first reduced by hunting, and then more recently by destruction of the juniper woodland by livestock grazing and fuel-wood gathering.  Climate change appears to be involved too. 


The Francolin is surviving in the dying juniper woodland and in less suitable neighboring vegetation. Please sign the petition to the Djiboutian Prime Minister to extend protections back over the Forêt du Day and establish captive breeding programs for the Francolin before this rare species disappears forever.

Speak up for California's Tricolored Blackbirds - Audubon California

Speak up for California's Tricolored Blackbirds - Audubon California | GarryRogers Biosphere News | Scoop.it

Responding to an alarming drop in the rare bird’s numbers, the California Fish and Game Commission this Wednesday will consider an emergency listing of the Tricolored Blackbird under the California Endangered Species Act. A statewide survey completed this summer shows a 44 percent decline in Tricolored Blackbirds since 2011. Audubon California is in favor of an emergency listing, but is also committed to continuing our partnerships with the agricultural industry.

Living Without Herbicides

The herbicides used to kill weeds have two undisputed dangers: They can poison arthropods and the animals that eat them, and they eliminate plants that are hosts for Monarch Butterflies and many o...
Garry Rogers's insight:

In 2007, I stopped using herbicides, insecticides, and chemical fertilizers on my farm.

New study shows that migration flyways and winter destinations of sparrows are unique to each bird

New study shows that migration flyways and winter destinations of sparrows are unique to each bird | GarryRogers Biosphere News | Scoop.it

"A new paper by Dr. Jeremy Ross from the University of Oklahoma describes the use of tiny devices strapped to birds' backs called geolocators, which capture the individual migration routes of  lark sparrows in North America. By sensing the light levels, these backpacks can pinpoint the location of a bird anywhere in the world, even if retrieving the data-logger can sometimes pose a major problem."

Garry Rogers's insight:

Animal cruelty outside the lab?  Does the geolocator bother the bird at all? Is it irritating or physically limiting?  Was its installation traumatic? It seems unlikely that any lark sparrow would volunteer to carry a backpack for the rest of its life just so someone could satisfy their curiosity. Could it choose, the sparrow might prefer that the researchers seek to find ways to preserve essential habitat and eliminate the herbicides and insecticides that poison the sparrow's food.
