Great-tailed Grackle
The great-tailed grackle or Mexican grackle (''Quiscalus mexicanus'') is a medium-sized, highly social passerine bird native to North and South America. A member of the family Icteridae, it is one of 10 extant species of grackle and is closely related to the boat-tailed grackle and the extinct slender-billed grackle. In the southern United States, it is sometimes simply referred to as "blackbird" or (erroneously) "crow" due to its glossy black plumage, and similarly it is often called ("raven") in some parts of Mexico, although it is not a member of the crow genus ''Corvus'', nor even of the family Corvidae. Description Great-tailed grackles are medium-sized birds (larger than starlings and smaller than crows; -) with males weighing - and females between -, and both sexes have long tails. Wingspan ranges from 18.9-22.8 in (48-58 cm). Males are iridescent black with a purple-blue sheen on the feathers of the head and upper body, while females are brown with darker wings and tai ...

Mexican Featherwork
Mexican featherwork, also called "plumería", was an important artistic and decorative technique in the pre-Hispanic and colonial periods in what is now Mexico. Although feathers have been prized and feather works created in other parts of the world, those done by the ''amanteca'' or feather work specialists impressed Spanish conquerors, leading to a creative exchange with Europe. Featherwork pieces took on European motifs in Mexico. Feathers and feather works became prized in Europe. The "golden age" for this technique as an art form was from just before the Spanish conquest to about a century afterwards. At the beginning of the 17th century, it began a decline due to the death of the old masters, the disappearance of the birds that provide fine feathers and the depreciation of indigenous handiwork. Feather work, especially the creation of "mosaics" or "paintings" principally of religious images remained noted by Europeans until the 19th century, but by the 20th century, the little ...

Iridescence
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change color as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, and minerals such as opal. It is a kind of structural coloration that is due to wave interference of light in microstructures or thin films. Pearlescence is a related effect where some or most of the reflected light is white. The term pearlescent is used to describe certain paint finishes, usually in the automotive industry, which actually produce iridescent effects. Etymology The word ''iridescence'' is derived in part from the Greek word ἶρις ''îris'' (gen. ἴριδος ''íridos''), meaning '' rainbow'', and is combined with the Latin suffix ''-escent'', meaning "having a tendency toward". Iris in turn derives from the goddess Iris of Greek mythology, who is the personification of the rainbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
