various types of sweet or savory empanada, originally introduced by Spain, and pancit, a noodle dish from the Philippines. Archeological evidence from islands in the Marianas reveals that rice was cultivated there since prehistory. Red rice made with achoti is a distinct staple food that strongly identifies Chamorro cuisine among the many dishes of fellow Pacific Island cultures. It is commonly served for special events, such as parties (gupot or "fiestas"), nobenas, and occasions such as a high-school or college graduations. The condiment fina'denne' accompanies most meals. Fruits such as lemmai, mangga, niyok, and bilimbines are consumed in various local recipes. In the Marianas, Korean, Chinese, Japanese, and American cuisine are also commonly available. Local cookies are known as guyuria. Locally distinct foods include kelaguen, a dish in which meat is denatured in whole or in part by citric acid rather than heat; tinaktak, a meat dish made with coconut milk; and kå'du fanihi (flying fox/fruit bat soup). Fruit bats and local birds have become scarce in modern times primarily due to the World War II-era introduction of the brown tree snake, which decimated the populations of local birds and threatens the fanihi'' (fruit bat) population, as well. Illegal hunting of fruit bats also threatens existing populations. Spam and other canned meats were introduced to the islands after World War II, leading to a dietary shift. Diaspora in the United States According to the 2010 census, 148,220 Chamorros are living in the United States, mostly from Guam, but also from the Northern Marianas and Saipan. The early Chamorros who migrated to the USA were Guamanians who moved in the first decade of the 20th century. In the following decades, small groups of Guamanians emigrated to Hawaii and the Western United States, where they worked as farmers. The population of Guam got the American citizenship in 1929. So, after the end of World War II, many more Guamanians emigrated to the US. Most of them were in the military or married with military people. In 1950, the population of Guam gained the full American citizenship, which favoured Guamanian migration to the US. So, the first major Guamanian migration emerged and more of 160 Guamanians emigrated to the US in the '50s. Many of them moved to California. In 1952, Guamanian immigrants founded their first organization in US, the Guam Territorial Society (later renamed as the Guam Society of America), in Washington,
