2011 is about to become 2012 and birders the world over are taking a look at their year lists and reminiscing about the awesome sightings and devastating dips that they have experienced. On Seymour Island, my group witnessed a very human-like interaction amongst three boobies , one female and two males.
From Birdlife International, “In 2010-2011 an American Mink Neovison vison, a new arrival on the Buenos Aires plateau, killed more than half the adults in a breeding colony of two dozen nests (Roesler et al. We only observed 6 breeding colonies, two in 2009/2010 and four in 2010/ 2011, totalling 242 nesting attempts. Roesler, I.;

Sorry we didn’t meet you.
As a backup plan, researchers captured some Spoonies in Siberia in 2011 and brought them to England , where they’ve been raised at the Wildfowl and Wetlands Trust (WWT) in Slimbridge, Gloucestershire. Two different females among the captive group have laid eggs , and scientists are keeping a watchful eye on a few others.
While many saw these multiple lines of evidence converging on one conclusion, Brad Livezey, up until his untimely death in a 2011 accident, maintained a very different perspective on the evidence. Modern flamingos build mud nests for a single egg, while modern grebes build nests of vegetation for multiple offspring.
Aerial view of the scale of the clean-up operation 6 January, 2011 The White House oil commission concludes that the oil spill in the Gulf of Mexico was the result of systematic management failure at BP, Transocean and Halliburton. October 26, 2011 BP is awarded a permit to drill another exploratory well in the Gulf of Mexico.
This one was spotted back on 1 January 2011 at Upper Newport Bay in Orange County, California, the first place I ever encountered Nutmeg Mannikins. Just as interesting is the nugget that Pin-tailed Whydah , an introduced species itself, has adapted to using Nutmeg Mannikins as a host for its eggs.
Red-capped Plover nest We have mostly observed Red-capped Plover nests with two eggs, so she may well have laid another egg by now. One of my favourite photos of a Red-capped Plover chick hiding from threats was taken in 2011 and the chick was able to hide in a footprint.
Fried-egg-on-a-sidewalk hot. It’s hot. Really hot. Sticky hot. Painfully hot. Hate-the-sun hot. Disgustingly hot. Wander-the-apartment-in-just-underwear hot. In other words, it is once again summer in New York City. Like last year I am doing my best to stay cool and thought I would try to help all of you wonderful readers do the same.
But, for right now, we are celebrating — both Ozzie and Harriet, the pair of Ospreys that have graced the nest platform at Dunrovin since at least 2011, are back once more. The many eyes on this particular citizen-science prize have also yeilded other results as well.
Early April is a fairly typical time for the earlier-migrating Osprey to arrive (both birds at Dunrovin are already onsite,) but eggs probably won’t appear until late April or early May. Because the stadium is by the river. And Osprey love them some nest platforms. Adaptation has its privileges!
Egg loss to predation has been extraordinarily bad this year and all of the nests mentioned in the last post were lost and all of the pairs of Pied Oystercatchers laid a new clutch of eggs. In fact they have not just laid once again, but many pairs have laid up to five clutches of eggs this season.

From what I read, birds are the class of Aves [feathered, winged, bipedal, warm-blooded, egg-laying and vertebrate animals]. Life, Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Also, and this is pretty cool, there are extinct birds that have different characteristics [no wings, for example. Who knew?].
One could have been just another cat-triggered tragedy ( keep your cats indoors ) turned into an unforgettable experience… My wife and I (retired) had a truly wonderful experience at the end of 2011 when our cat brought in a newly hatched Dikkop. We raised this little fella to a young adult.
The breeding season in the north of Australia starts from about July 1st and there are often several attempts if the eggs fail, are lost or the chicks don’t survive. On July 1st 2007 an egg was laid by a Pied Oystercatcher that was known to be an adult in 2002 and had been banded in nearby Roebuck Bay.
To the north they are very unlucky with predation before the eggs even hatch out, but to the south the eggs hatch out and then the predation occurs on the chicks. A normally quiet species, that walks a lot more than it flies, takes on a whole new role once it has laid eggs.
This is a 44% reduction from the 258,000 birds seen during the 2011 Survey and a 63% reduction from the 395,000 birds seen during the 2008 Survey. It appears to have been the most comprehensive Statewide Survey ever, with 143 participants surveying for tricolors at 802 locations in 41 counties. www.youtube.com/watch?
A typical distant photograph was taken in May 2011 at an ephemeral lake near Broome. The female is polyandrous and can defend a large territory laying several clutches of eggs (usually four) in nests built by male birds. They feed on insects and seeds as they pick through the floating vegetation and they do not feed their young.
In 2011, a collaborative effort among state and federal wildlife agencies teamed up with Louisiana’s Department of Wildlife and Fisheries to begin releasing captive-bred birds into the White Lake Wetlands Conservation Area. A pair from the released batch set up housekeeping last month and lo and behold, eggs gave way to chicks.
When we eat eggs we eat chicken eggs almost exclusively. Feral Chickens number in the thousands in Key West alone and that population has not been dented even as hundreds of birds are trapped and removed – in fact, in 2011 0ver 1,500 were captured and trucked to an organic farm in central Florida. Americans love chicken.
Penguins are shown individually in groups, in dense colonies, within habitat (ice, rainforest, beach), swimming in the ocean, and doing things–nose to nose with an albatross, feeding a child, placing an egg on its foot, sliding down ice. Press, 2011). Davis and Martin Renner in 2003, appropriately titled Penguin s (Yale Univ.
Here are three excellent but very different children’s books I enjoyed this year (two were published in 2013, one in 2011). They cut down the trees the parrots used for nesting and brought black rats, who ate their eggs, and honeybees who swarmed into their nests, and by 1937 there were only about 2,000 Puerto Rican Parrots left.
July 8, 2011 – In a groundbreaking move that should result in the greatest advancement for farmed animals in U.S. history, the United Egg Producers (UEP) has agreed to support national legislation that will, upon enactment, improve the welfare of all laying hens in the nation.

Or, Pygmy leaf-folding frogs, Afrixalus brachycnemis, from Tanzania, tiny climbing frogs who lay their eggs in leaves and then fold the leaves over them for protection, sealing the nest with secretions. The male and female position themselves close to each other, on top or in back, so that the eggs are fertilized as the female releases them.
Image by Adam Riley Since 2011, the list of Critically Endangered species (meaning they are facing an extremely high risk of extinction) has risen from 189 to 197, and Endangered (facing a very high risk of extinction) from 381 to 389. A pair of Hooded Vultures in Selous Game Reserve, Tanzania by Adam Riley.
In 2011 their population was estimated at over 3,000 individuals, increasing steadily at 5-8% every year. The most notorious effect is that their eggshells become so thin that a parent bird will crush it’s eggs while attempting to incubate them.
The good news is that Kirtland’s Warbler numbers are up, 1,828 singing males counted in the 2011 census. A nest wasn’t found until 1903, which set off a craze for Kirtland’s Warbler skins, nests, and eggs. Less than 200 singing males were found in the 1987 census, and this was 20 years after it had been placed on the U.S.
The first time we ever observed an Australian Painted Snipe was on Grant’s birthday in 2011 near Broome and since then we have had numerous other encounters, but this year for the first time we have seen them both nesting and with young. Australian Painted Snipe nest with four eggs. Four eggs in the Australian Painted Snipe nest.
To the Editor: Re “ Egg Producers and Humane Society Urging Federal Standard on Hen Cages ” (Business Day, July 8): I’m a vegetarian who turned vegan after coming to terms with the fact that just because I was eating hormone-free, antibiotic-free, even free-range organic eggs didn’t mean that egg-producing hens were living a cruelty-free life.
Hal Herzog’s “ Some We Love, Some We Hate, Some We Eat ” (Harper 2011), though fascinating, is ultimately depressing for vegans and animal rights activists. Over at Animal Rights and AntiOppression , we’ve been discussing tactics and sharing our thoughts and experiences about what works and doesn’t work when it comes to advocacy.

About three billion birds fly north to the Boreal Forest each spring to build nests and lay eggs. This is a photograph of the same area in 2011. As of September 2011, roughly 663 square kilometers (256 square miles) of land had been disturbed for oil sand mining 3. For many waterfowl, this area is their only nesting ground 2.
With a hardiness that belies their delicate looks (but helps explain their phenomenal success), these pioneering pigeons are already sitting on eggs at at least one location in Montana. Nicole Mar 11th, 2011 at 10:49 pm I’ve always like the Collared doves. Carrie Mar 13th, 2011 at 1:26 pm @Will: I was curious about that myself.

Corey did just this in this 2011 posting about Vesper Sparrow Pooecetes gramineus in New York State. For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area.
Alternatively, imagine I set the dial to produce simple heat, like the kind that comes out of your stove to cook your scrambled eggs. The kind of energy produced by a cell phone signal is way more like the heat that cooks your eggs than like the scary radiation that comes form an H-bomb or X-ray machine or whatever. 0016862 a.
The where and how of egg laying and larva emergence is briefly treated, with page references to larval drawings at the back of the book. Life cycles of odonata are described with a minimum of scientific language, accompanied by photographs illustrating stages–egg laying, larva, emergence, aging, mating, dispersal.
In 2011, my wife and I sailed into a beautiful little anchorage here in the Sea of Cortez, on Isla Espritu Santos. Each nesting pair will have 4-8 eggs, and there is some reference to location being a factor on that quantity. Years went by, and I had still not been able to track down a real live shrike to add to my list.
Foxes have also been known to take their eggs and there are now numerous local groups who endeavour to help the populations of Hooded Plovers along their local coastlines. In 2011 they appeared all over Australia in much larger numbers than previously experienced and these unknown populations are always a pleasant surprise.
