Emperor Penguin Visits New Zealand Beach

Local man admires visiting Emperor Penguin on Peka Peka Beach on the North(!) Island of New Zealand

For the first time in 44 years, an estimated-to-be 10-months-old Emperor Penguin (Aptenodytes forsteri) waddled ashore on Peka Peka Beach near the bottom of the North Island of New Zealand yesterday, approximately 2,000 miles (3,200 kilometers) from its native Antarctic waters.

The immature Penguin is roughly 31” tall. Emperor Penguins are the largest Penguin species and can reach 48”.

News reports are indulging in the usual kinds of empty speculation. Reports of the Penguin’s possible thirst (it has been observed to be eating wet sand) are probably not well-founded. Penguins can drink salt water.

The only other confirmed sighting of a wild Emperor in New Zealand was in 1967 at the southern Oreti Beach.

The Vanished Wild Bobwhite

William Herman Schmedtgen, Quail Shooting in Louisiana, 1897

A couple of generations ago, coveys of wild bobwhite quail could be found by hunters from Florida as far north as Southern New Jersey and Pennsylvania. Today, quail hunting exists only for pen-raised, released birds on pay-for-shooting preserves and plantations.

What happened to wild quail? Where did they all go?

The New York Times discusses the problem and advances a theory.


Quail hunting has been both aristocratic and egalitarian. It is a sport of Southern plantation gentry who ride walking horses with bespoke double guns in their scabbards and have pedigreed pointing dogs racing across the fields before them. It is also the sport of the farm kid armed with a dad’s old shotgun and a rangy mutt for a hunting companion. Both types of hunters have equally satisfying hunts, but these days social standing does not matter. Everyone is quail-poor. Bobwhite quail are one of the most studied wildlife species in the United States, yet conservationists have yet to halt the declining populations.

Biologists agree that overhunting is not the issue. Quail are prolific breeders but have a short lifespan. Hunting seasons could be eliminated and still approximately 90 percent of the quail would be dead within the year. Other predators, like raptors, coyotes or raccoons, are also not the reason for their decline, although many hunters point the finger at them.

Don McKenzie is in charge of the National Bobwhite Conservation Initiative, a team of 25 state fish and wildlife agencies and conservation groups. The goal of the group, formed in 2002, is to get wild quail populations to what they were in 1980.

It is one of the most difficult large-scale wildlife restoration projects. Canada geese, whitetail deer and wild turkeys — all at one time low in numbers — have become so populous that they spill into the suburbs, but bringing back bobwhite populations is a struggling enterprise.

“One of the difficult parts of quail restoration is we have to restore suitable habitat at a landscape scale,” McKenzie said. “When you compare that with deer and turkey restoration, the habitat was already suitable. It was a matter of catching remaining wild animals in places where they were and moving them to places where they weren’t and protecting them until they took care of themselves. It’s still a challenge, but nothing compared to what we face now with bobwhites.”

The reason restoring bobwhite quail is so difficult is because it involves changing the nation’s manipulated rural landscape. According to McKenzie, exotic fescue, Bahia grass and Bermuda grass took hold across the United States in the 1940s. These carpetlike grasses were planted to promote better cattle grazing and edged out the native warm-season grasses that are conducive to good quail habitat. The native grasses grow in clumps, which allow the quail to hide, move and forage and are essential to their survival.

With pastures covered with invasive exotic grasses, the quail found cover along brushy fencerows and field edges, but by the 1970s modern agricultural practices that maximized every inch of soil devoured these small sanctuaries and left quail with few hideouts.

Wildlife biologists have known about this connection between warm-season grasses and quail habitat, and many landowners have tried to create an oasis for quail on their property by planting a paradise of native plants. Yet the quail population never reached the old numbers.

“Resident game bird conservation professionals have been telling landowners this for 50 years: all you need to do is some small-scale stuff on your place and you’ll have birds and everything will be fine,” McKenzie said. “Well, after 50 years of doing that, it certainly doesn’t work.”

The problem is that the islands of prime quail habitat — restored or naturally occurring — are not connected to one another to create larger plots of good habitat where quail have greater odds of survival.

“We have to come up with bigger pieces of landscape that are managed in common, and have connections with other pieces of well-managed landscape where there are sustainable populations of birds,” McKenzie said. “We must make it happen by the millions of acres instead of by the tens of acres.”

The problem is not restricted to bobwhite quail. The Times overlooks the fact that same thing has happened to the ringnecked pheasant in the Eastern United States.

Up to the 1960s, the Asiatic pheasant had been successfully naturalized for many decades, and wild pheasant populations existed from Maryland and Virginia all the way up to Southern New England.

As with the bobwhite quail, one finds today everywhere in the East, the wild pheasant population has been completely eliminated. The State of Pennsylvania stocks thousands of pen-raised pheasants annually, and it makes no difference. Within weeks, the birds are gone.

I think the Time’s authorities are correct that edge-to-edge farming, encouraged by the Department of Agriculture’s experts, had something to do with all of this, and the altered system of grasses theory has some plausibility, but I think there may be more to it than that. I don’t see how the complete protection of raptors cannot be playing a role. And, beyond that, experience shows that populations of wild birds and animals do change dramatically and unpredictably.

Back before WWII, Canada geese were becoming very scarce and some subspecies were even believed to be nearing extinction. The wood duck was rare, and had been removed from the bag list of huntable species. In those days, the prime hunting ducks were black ducks in the Northeast, and canvasbacks in the Chesapeake.

Today, Canada geese are a public nuisance. They’ve stopped migrating. Their population has exploded, and the once less common larger subspecies is a standard inhabitant of malls, office complexes, and parks. Wood ducks are now common and have the largest bag limit, and it is unusual to ever get a shot at a black duck or a canvasback.

I don’t think the experts have a good explanation for all the wildlife population changes which occur over time.

Foxes Get Around

And they clearly have terrific noses for food, as this Sun story repeated by MSNBC demonstrates.


A fox cub was found living at the 72nd floor of the U.K.’s tallest skyscraper, it was reported Friday.

The animal, estimated to be six months old, had lived for at least two weeks on scraps of food left by workers about 945 feet up in the under-construction Shard tower in London, The Sun newspaper said.

Pest controllers managed to catch the fox and it was released near London Bridge after a health check, the tabloid reported. London is home to a large population of urban foxes.

“It was unbelievable,” local government official Les Leonard told The Sun. “To get up there the fox would have had to climb 71 sets of stairs and an old-fashioned ladder.

“We finally caught him in a large fox cage, baited with chicken carcasses.”

Library of Congress Hawk

Cooper's Hawk, Falconry, Library of Congress, Natural History

The Library of Congress isn’t sure, but they think that they have a Cooper’s Hawk (Accipter cooperii) currently in residence in the main reading room. (You’d think there’d be a copy of Roger Tory Peterson in there somewhere.)

They also don’t know how to catch it.

The preferred method of reducing raptors to possession is a device called a bal-chatri, a small wood or metal cage covered with loops of monofilament (in the old days, horsehair). You place a pigeon in the cage, drop the cage on a reading room table, and go away. The hawk goes for the pigeon and gets his feet entangled in the loops. You return and there’s your hawk.

Jack Russell Trees Lion in South Dakota

Jack Russell Terriers are small dogs who don’t know their own size, as this case from Eastern South Dakota demonstrates. The valor of this particular terrier attracted international attention, and one of the best accounts is the one from the British Daily Mail.


It was a David and Goliath style battle that few would have thought possible.

But with the odds stacked against him, Jack the plucky Jack Russel chased a deadly mountain lion high into a tree.

The cornered lion remained trapped above the ground before the Jack Russel was able to pounce a few minutes later.

Jack’s owner, Chad Strenge, witnessed the astonishing scenes while he was walking Jack on farmland in South Dakota.

The pair had been hunting when Mr Strenge heard Jack barking frantically several hundred yards away.

Thinking that his heel-biting Jack Russel – a breed known for their high energy levels- might have caught a squirrel, Mr Strenge raced to a patch of dense woodland.

Incredibly, the 150lb mountain lion was trapped high in the branches while 17lb Jack bayed for his blood below.

‘He trees cats all the time. I suppose he figured it was just a cat,’ said Mr Strenge. ...

Mr Strenge shot at the lion which knocked it from the tree. Jack then chased the lion over a short distance before Mr Strenge killed it with his gun.

Professor Jonathan Jenks, an expert on cougar migration, said hunters usually needed two or three hounds to chase a lion up a tree.

He said: ‘The cougar was probably not hungry enough to attack Jack.

‘It very well could have lost a territory and decided to take off from the Black Hills and head this way.’

Arden Petersen, of the South Dakota Game, Fish and Parks department, said that no charges would be filed for shooting the animal.

People in South Dakota have the right to kill mountain lions which they feel are a threat to themselves, their livestock or their pets.

The lion was taken to South Dakota State University, where it will be studied.

Bear v. Bison

Bison, Grizzly Bear, Natural History, Photography, Viral Entertainment, Yellowstone

An amateur photographer with a habit of driving around inside Yellowstone National Park in his spare time taking shots of wildlife last month encountered a grizzly bear pursuing with intent an injured bison.

The photographs were taken around 7 AM at the Fountain Flats area, located between the Madison Junction and Old Faithful inside the Park.

The unfortunate bison had blundered into one of Yellowstone Park’s hot springs and was badly injured. As events unfolded, the bison managed to outrun the bear, but it was subsequently concluded to be too badly burned to recover and was put down by Park rangers. It seems a pity that the bear lost the race.

KTVQ reports.

The photographs have gone viral, and have been published in many places, including Field & Stream.

One More Warmlist Entry

Global Warming, Grizzly Bear, Human Predation, Montana, Wyoming

line

It is always a good day for NYM when we are able to add one more dire effect to the Warmlist catalogue.

Julie Cart, at the LA Times, consults the environmental seers who explain that grizzly bear predation on humans in Wyoming and Montana results from Global Warming.


A number of complex factors are believed to be working against grizzlies, including climate change. Milder winters have allowed bark beetles to decimate the white-bark pine, whose nuts are a critical food source for grizzlies. Meanwhile, there has been a slight seasonal shift for plants that grizzlies rely on when they prepare to hibernate and when they emerge in the spring, changing the creatures’ denning habits.

The result, some biologists say, is that bears accustomed to feasting on berries and nuts in remote alpine areas are being pushed into a more meat-dependent diet that puts them on a collision course with the other dominant regional omnivore: humans.

Of course.

What Are Those Dark Spots On That Dam?

Look closer.

These photographs are being widely distributed on the Internet, with the caprids misidentified as Bighorn sheep.

The location is actually Lake Cingino, a reservoir created by adding a dam and enlarging a small lake in the Valley of Antrona in the Italian Alps.

The animals on the dam are chamois Alpine Ibex, Capra ibex, who apparently frequent the dam face in search of salts that accumulate on the rocks of the dam.

Maurizio Piazzai has a couple more photos of chamois Alpine Ibex on the Lake Cingino dam here.
———————————————————
Correction:

I had originally misidentified the animals on the dam as chamois, believing that the range of the Alpine Ibex in Italy was still limited to Gran Paradiso National Park. The absence in available photos of any full-horned rams faciliated my misidentification.

This factsheet shows that the current range of Alpine Ibex definitely includes the Valle Antrona.

Thanks to John Burchard for the correction.
