The sword-billed hummingbird (Ensifera ensifera) is a neotropical species of hummingbird from the Andean regions of South America. Among the largest species of hummingbird, it is characterized by its unusually long beak, being the only bird to have a beak longer than the rest of its body, excluding the tail. It uses this to drink nectar from flowers with long corollas and has coevolved with the plant Passiflora mixta. While most hummingbirds preen using their beaks, the sword-billed hummingbird uses its feet to scratch and preen due to its beak being so long.
The Valère Basilica is a fortified Catholic church in Sion, in the Swiss canton of Valais. It is situated on a hill at an altitude of 615 metres (2,018 ft), and faces Tourbillon Castle located on the opposite hill. The first parts of the building were constructed around 1100, with numerous additions over the subsequent centuries. It was designated a minor basilica in 1987. The site is a listed as a Swiss heritage site of national significance, which includes the surrounding hill due to the large number of protected plant and animal species present there. This photograph shows the Valère Basilica in February 2021, with the Haut de Cry, a 2,969-metre (9,741 ft) peak of the Bernese Alps, in the background.
Operation Title was an unsuccessful 1942 Allied attack on the German battleship Tirpitz during World War II. The Allies considered Tirpitz to be a major threat to their shipping and after several Royal Air Force heavy bomber raids failed to inflict any damage it was decided to use Royal Navymidget submarines instead. Operation Title involved a pair of two-man British Chariots which were transported to Norway on board a small boat named Arthur. Both Chariots were lost when bad weather caused them to detach from Arthur on 31 October. It was not possible for the Allied boat to reach the sea due to German security measures, and Arthur was scuttled. The Allied personnel attempted to escape overland and all but one reached neutral Sweden on 5 November. The other – a British serviceman – was taken prisoner by German forces and murdered on 19 January 1943. Tirpitz was eventually sunk by another bomber raid on 12 November 1944. (Full article...)
Hö'elün (fl. 1162–1210) was a Mongolian noblewoman and the mother of Temüjin, better known as Genghis Khan. She played a major role in his rise to power. Born into the Olkhonud clan of the Onggirat tribe, Hö'elün was originally married to Chiledu, but was captured shortly after her wedding by Yesügei, an important member of the Mongols, becoming his primary wife. She and Yesügei had three sons and one daughter, as well as Temüjin. After Yesügei was fatally poisoned and the Mongols abandoned her family, Hö'elün shepherded all her children through poverty to adulthood—her resilience and organisational skills have been remarked upon by historians. She continued to play an important role after Temüjin's marriage to Börte. Hö'elün married Münglig, an old retainer of Yesügei, in thanks for his support after a damaging defeat. During the next decades, she arranged marriages, maintained alliances, and was heavily involved in disputes between Genghis, his brothers, and Münglig's sons. (Full article...)
