Hilary Hanson: Scientists Discover Adorable Bird That's Actually 3 Species In One

By Dilip -
A striking yellow, black and white bird spotted in Pennsylvania is actually a hybrid between three different species, according to a news release from the Cornell Lab of Ornithology. Extremely observant bird watcher Lowell Burket saw the male bird in the borough of Roaring Spring in May. He noticed that the bird had the physical attributes of the blue-winged warbler and golden-winged warbler, but sang like a third species, the chestnut-sided warbler. 
LOWELL BURKET

The bird piqued his interest enough that after taking photos and video, he contacted the Fuller Evolutionary Biology Lab at Cornell. “I tried to make the email sound somewhat intellectual so they wouldn’t think I was a crackpot,” he said in the release. Luckily, the lab did not think Burket was a crackpot, and researcher David Toews soon got in touch with him. Together, they found the bird again and took a blood sample and measurements for ID purposes.

As it turned out, Burket’s suspicion was right. DNA analysis showed that the bird’s mother was a hybrid between golden-winged warbler and a blue-winged warbler, while the father was a chestnut-sided warbler. The results of the analysis were published this week in the science journal Biology Letters. The paper notes that the mix is especially significant because the bird’s mother and father weren’t just different species, but also different genera. Golden- and blue-winged warblers are both part of the Vermivora genus, while chestnut-sided warblers are part of the Setophaga genus.

Researchers suspect this three-way hybridization ultimately happened in part because of declining numbers in the local population of golden-winged warblers, leaving females with fewer potential mates. In response, they may be “making the best of a bad situation” by selecting mates outside of their own species and genus, researchers wrote. As for the rare new hybrid, he’s hopefully enjoying some warmer weather at the moment. “The bird was released with a [United States Geological Survey] aluminum band and was seen on the property until about late August, after which it wasn’t seen again,” Toews told HuffPost in an email. “Presumably it migrated south for the winter!”

History Archive: Communist Party of India's resolution on Pakistan and National Unity, September 1942

By Dilip -
Pakistan and National Unity is an important position paper of the Communist Party of India, and a far-reaching text in the history of the Indian communist movement. The resolution dated September 19, 1942 contains an outline of the CPI's support for what it called the 'just essence of the Pakistan demand'; and the Report by Gangadhar Adhikari is a detailed explanation of the resolution. The resolution was confirmed by the First Congress of the CPI in May 1943.  Its arguments may be contrasted with the pamphlet titled Who Rules Pakistan? published in Bombay in August 1948, as a 'Communist Party publication' - and is one of the earliest position documents of the Communist Party of Pakistan.  The document is titled File CPI-31/1942 ; and forms part of the P.C. Joshi Archives at Jawaharlal Nehru University, New Delhi. The text of the resolution and report is also available in the book entitled Remembering Dr  Gangadhar Adhikari: Selections from Writings, Part 2 ; e...

Pakistan's First Law & Labour Minister, Jogendra Nath Mandal's Resignation Letter, October 1950

By Dilip -
Mr. J.N. Mandal, Minister for Law and Labour, Government of Pakistan On 8th October, 1950 My Dear Prime Minister, It is with a heavy heart and a sense of utter frustration at the failure of my life-long mission to uplift the backward Hindu masses of East Bengal that I feel compelled to tender resignation of my membership of your Cabinet . It is proper that I should set forth in detail the reasons, which have prompted me to take this decision in this important juncture of the history of Indo-Pakistan Sub-continent. (1)  Before I narrate the remote and immediate causes of my resignation, it may be useful to give a short background of important events that have taken place during the period of my co-operation with the League, Having been approached by a few prominent League leaders of Bengal in February 1943, I agreed to work with them in the Bengal Legislative Assembly. After the fall of the Fazlul Haque Ministry in March 1943, with a party of 21 Scheduled Caste M.L.As,...

The Almond Trees by Albert Camus (1940)

'Do you know', Napoleon once said to Fontanes, 'what astounds me most about the world?  The impotence of force to establish anything.  There are only two powers in the world: the sword and the mind.  In the end, the sword is always conquered by the mind' Conquerors, you see, are sometimes melancholy.  They have to pay some price for so much vainglory. But what a hundred years ago was true of the sword is no longer true today of the tank. Conquerors have made progress, and the dismal silence of places without intelligence has been established for years at a time in a lacerated Europe. At the time of the hideous wars of Flanders, Dutch painters could still perhaps paint the cockerels in their farmyards. The Hundred Years War has likewise been forgotten, and yet the prayers of Silesian mystics still linger in some hearts. But today, things have changed; the painter and the monk have been drafted - we are one with the world.  The mind has lost that regal certai...

Anand A. Yang, Kamal Sheel, Ranjana Sheel: Thirteen Months in China: A Subaltern Indian and the Colonial World.  New Delhi, 2017 Reviewed by Emily Whewell  Printable Version:  http://www.h-net.org/reviews/showpdf.php?id=53231 Thirteen Months in China  is an annotated translation of Gadadhar Singh’s 1902 self-published book,  Chῑn Me Terah Mᾱs , a British Indian soldier’s perspective and experience in China during the Boxer Uprising. The Boxer Uprising at the turn of the twentieth century was a key moment in Sino-foreign relations. The rebellion ended with the suppression of the anti-foreign Boxers and the liberation of the foreign legations by a military force comprising of eight foreign nations. This “International Expedition” included British forces, with the majority of British soldiers belonging to Indian regiments. The uprising’s suppression also came at a cost to lives, homes, and livelihoods. Singh’s account gives an insight into how one ...

Ben Marks - The Mao Mango Cult of 1968 and the Rise of China's Working Class

By Dilip -
For 2,000 years, the peach was the iconic fruit of China, an auspicious symbol of good health and a long life. But from August of 1968 until roughly the fall of the following year, the mango was China’s most revered produce item, whose meaning was unwittingly bestowed upon it by none other than Mao Zedong. Now an  exhibition  about the mango’s short-lived sanctification has opened at Museum Reitberg in Zurich, Switzerland. Continuing through June 16, 2013, the show is organized around more than 60 Mao-era mango items—from Mao mango medallions to textiles bearing mango imagery—donated to the museum by scholar and author Alfreda Murck, who also edited the exhibition’s  catalog  and will be speaking at the  Capital Literary Festival  in Beijing on March 2, 2013. The circumstances leading to the mango’s prominence as a symbol of the working class have their roots in 1958, when Mao Zedong instituted a series of agricultural and industrial reforms...

Karl Marx: Letter to Abraham Lincoln, President of the United States of America; 1865

By Dilip -
Address of the International Working Men's Association to Abraham Lincoln, President of the United States of America Presented to U.S. Ambassador Charles Adams January 28, 1865 The workingmen of Europe... consider it an earnest of the epoch to come that it fell to the lot of Abraham Lincoln, the single-minded son of the working class, to lead his country through the matchless struggle for the rescue of an enchained race and the reconstruction of a social world.  Sir: We congratulate the American people upon your re-election by a large majority. If resistance to the Slave Power was the reserved watchword of your first election, the triumphant war cry of your re-election is Death to Slavery.  From the commencement of the titanic American strife the workingmen of Europe felt instinctively that the star-spangled banner carried the destiny of their class. The contest for the territories which opened the dire epopee, was it not to decide whether the virgin soil of immense ...
