Did the South american hoatzins originate in Europe? The oldest fossil discoveries from France show that hoatzins once existed in Europe.
Where did hoatzins come from? These unusual birds only one species of which exists in South america today originated in the Old world.
Studies of the oldest known fossils of Hoatzin ancestors have shown now that these birds existed around 34 million years ago in Europe.
Paleornithologists at the Senckenberg Gesellschaft fã r Naturforschung and Flinders University in Adelaide published their findings this week in the specialist journal Naturwissenschaften.
The Hoatzin (Opisthocomus hoazin) is also known as the Stinkbird or Canje Pheasant and today exists only in parts of South america.
and new discoveries from Africa and Europe now prove conclusively that hoatzins reached South america from the Old world.
A study published in January 2014 in the ornithological journal The Auk provided the very first evidence of largely modern Hoatzins from the Miocene (15 million years ago) in Africa.
The oldest fossils attributed to hoatzins were found more than 100 years ago near Paris . But only now have paleornithologists been able to show that these remains belong to ancestors of the modern Hoatzin.
The fossils belong to a newly described species Protoazin parisiensis (proto-Hoatzin from Paris). The re-interpretation of these bones indicates that hoatzins lived in Europe as early as the late Eocene i e. around 34 million years ago.
This supports the theory that hoatzins originated in the Old world says Dr Gerald Mayr of the Senckenberg Research Institute in Frankfurt.
In the opinion of Dr Vanesa De Pietri of Flinders University in Australia it is a further impressive example that the South american avian fauna contains numerous relicts that were once much more widespread.
Most notably Hoatzins appear to have become extinct in Europe much earlier than in Africa where the latest fossils were dated as of Miocene age (15 million years ago)
These included tree-dwelling carnivorous mammals who may have posed a threat to hoatzin nestlings which are raised in open nests.
Because hoatzins can fly short distances only the adult birds are also easy prey. In Africa by contrast similar tree-dwelling carnivorous mammals are shown to have existed much later.
Digestion specialist and climbing artistthe present-day Hoatzin exhibits a special mode of digestion. These herbivores predigest their food in this crop before further processing in the stomach and intestines.
Skeletal features show that Old world hoatzins already had a large crop. Another special feature of the Hoatzin are the claws on the wings of the chicks
which enable the hatchlings to climb trees. Story Source: The above story is provided based on materials by Senckenberg Research Institute and Natural history Museum.

#Might more ravens--aided by humans--mean nevermore for sage-grouse? A new study by the Wildlife Conservation Society Idaho State university and the U s. Geological Survey suggests that habitat fragmentation
and the addition of makeshift perches such as transmission polls in sagebrush ecosystems are creating preferred habitat for common ravens that threaten sensitive native bird species including greater sage grouse.
Along with the eggs and nestlings of greater sage grouse ravens also prey on the federally endangered Desert tortoise the endangered San Clemente Loggerhead shrike and the California Least Tern.
The authors state Such an increase likely poses an increased threat to sagebrush steppe species subject to raven depredation including sage-grouse for
and food resources for a wealth of species including sage-grouse pronghorn and mule deer. Poor livestock grazing management invasive species such as cheatgrass transmission lines energy development and subdivisions are all contributing to the loss of this vital resource.
Don't expect a decrease in turkey waste at future Thanksgivings. It would take a major cultural shift for Americans to change their holiday eating habits,
Plus, there's hardly an incentive for the turkey industry to produce smaller turkeys. Quite the opposite.
It's much more efficient to produce fewer, larger turkeys. And that's exactly what the industry is doing.
Last year, 45 million fewer turkeys were produced than in 1995. But in the past decade the size of the turkey is getting bigger
meaning larger turkeys at meals and more opportunity for waste. But food waste isn't just a problem at Thanksgiving.
In fact, the U s. has a $165 billion food waste problem. This Thanksgiving, Be More Grateful than Wasteful NRDC Switchboard Photo:

Super bug bacteria in meat and poultry, study saysif you grab chicken or some other meat from the grocery store,
Scientists at the Translational Genomics Research Institute (TGEN) looked at nearly 140 samples taken from 80 brands of beef, chicken, pork and turkey.
