Rare harpy eagle hatches at Miami Metrozoo

Wildlife News



It is the national bird of Panama and is depicted on the nation's coat of arms.

It is one of the largest of the 50 species of eagles, about half the length of an average sized human.

It can reach speeds of 50 mph in flight.

In the wild, they eat opossums, and monkeys.

Meet the harpy eagle chick, the newest resident of Miami Metrozoo.

The chick, which is yet to be named, was born Sept. 22, but because mortality rates are so high for baby eagles, the zoo had to wait 30 days before announcing its birth.

"I've been sitting here for 30 days saying īPlease God let it live, please God let it live,''' said Metrozoo spokesman Ron Magill.

40,000 salmon escape B.C. farm

VANCOUVER (CBC) - About 40,000 Atlantic salmon have escaped from a fish farm on the B.C. coast.
Marine Harvest Canada says the fish escaped Wednesday from its farm at Port Elizabeth, on the Pacific Coast about 400 kilometres northwest of Vancouver.
The company says divers discovered several holes in two pens at the farm and efforts are being made to prevent more escapes from the pens, which still hold thousands of fish.
"Through the night Wednesday we had people working at the farm site to stop up the holes and reverse any ongoing problem with the escape," said Clare Backman, Marine Harvest's environmental compliance officer.
The Living Oceans Society environmental group says hundreds of thousands of farmed salmon escape every year.

Arachnophobics beware: Researchers identify giant new spider species

By Sheryl Ubelacker, The Canadian Press

For anyone who suffers from arachnophobia, it might be advisable to read no further.
That's because this is a story about a spider - a very BIG spider.
Researchers have discovered an entirely new species of arachnid, and its gargantuan female members represent the largest of its family ever found.
Dubbed Nephila komaci, this sucker has a tip-to-tip leg span of about 12 centimetres, including a body almost four centimetres wide. To get an idea how big that is, imagine the size of a man's hand or a small saucer.
"They look like they're all legs ... They live in webs, right, so they're spindly, relatively delicate spiders," said Jonathan Coddington, an arachnologist at the Smithsonian Institution's National Museum of Natural History in Washington, one of the scientists who identified the new species.
"If you were standing there, you wouldn't say that. You would probably freak out. Most people do."

Mass Stranding of Squid off Vancouver Island

Two mass strandings of Humboldt squid in the last two months on the West Coast have locals asking the question no one seems to be able to answer: why is this happening?


Though no one has the exact answer, scientists aren't short on theories and speculation. Some say perhaps the squid were following their prey and got caught in a current that washed them ashore.

Others think maybe the squid were disoriented by a change in one (or all of) several ocean conditions: temperature, salinity, or oxygen levels. Some have even suggested strandings could be a result of old age in a cephalopod that tends to have a life span of two years at most; the pack simply follows one senile leader and they all end up on the beach at the same time by accident.

Conservation: Minimum Population Size Targets Too Low To Prevent Extinction?

ScienceDaily (Oct. 20, 2009) — Conservation biologists are setting their minimum population size targets too low to prevent extinction.


That's according to a new study by University of Adelaide and Macquarie University scientists which has shown that populations of endangered species are unlikely to persist in the face of global climate change and habitat loss unless they number around 5000 mature individuals or more.

The findings have been published online in the journal Biological Conservation.

"Conservation biologists routinely underestimate or ignore the number of animals or plants required to prevent extinction," says lead author Dr Lochran Traill, from the University of Adelaide's Environment Institute.

"Often, they aim to maintain tens or hundreds of individuals, when thousands are actually needed. Our review found that populations smaller than about 5000 had unacceptably high extinction rates. This suggests that many targets for conservation recovery are simply too small to do much good in the long run."
