Bird

Birds (class Aves) are a group of endothermic vertebrates, characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.

The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago, and the last common ancestor is estimated to have lived about 95 million years ago. DNA-based evidence finds that birds radiated extensively around the time of the Cretaceous–Paleogene extinction event that killed off the non-avian dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like "stem-birds" that lie outside class Aves proper, in the group Avialae, have been found dating back to the mid-Jurassic period. Many of these early stem-birds, such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks and long bony tails.

Birds (Coldplay song)

"Birds" is a song by British alternative rock band Coldplay. It was produced by the band's long time producer Rik Simpson along with Norwegian production duo Stargate. It appears as the second track on their seventh studio album A Head Full of Dreams (2015).

Music video

An official music video was also released by the band. The video was directed by Marcus Haney. It was set to the back drop of Colorado Desert's famous Salvation Mountain. The entire video was shot on a Super 8mm camera. The director wrote on Instagram: "It's a tribute of thanks to the late artist Leonard Knight for creating Salvation Mountain and bringing so much joy to everyone who's come across it."

Critical reception

Stuart Berman of Pitchfork Media called the song "a shot of taut, Phoenix-styled motorik pop that provides a rare moment of intensity on an album that’s all about arm-swaying, Super Bowl-crashing bombast".

Trace (album)

Trace is the first album by Son Volt, released in 1995. The band was formed the previous year by Jay Farrar after the breakup of the influential alt-country band Uncle Tupelo. The album reached #166 on the Billboard 200 album chart and received extremely favorable reviews. According to Allmusic, "Throughout Son Volt's debut, Trace, the group reworks classic honky tonk and rock & roll, adding a desperate, determined edge to their performances. Even when they rock out, there is a palpable sense of melancholy to Farrar's voice, which lends a poignancy to the music." The album was in the top 10 of Rolling Stone's 1995 critics' list.

"Drown" was a minor college and rock radio hit. It charted at #10 on the Billboard Mainstream Rock Tracks chart and #25 on the Billboard Modern Rock Tracks chart. It remains their only single to chart on either of the charts.

Track listing

All of the songs were written by Farrar except "Mystifies Me", written by Ronnie Wood.

Trace (linguistics)

In transformational grammar, a trace is an empty (phonologically null) category that occupies a position in the syntactic structure. In some theories of syntax, traces are used in the account of constructions such as wh-movement and passive. Traces are important theoretical devices in some approaches to syntax.

Concept

A trace is usually what occupies the empty (null) position in the syntactic structure that is left behind when some element undergoes movement. For example, in a case involving wh-movement, a structure like

is transformed into

the wh-word what being moved to the front of the sentence. In theories that posit traces, the position from which the wh-word was moved (in this case, the position of the direct object of eating), is considered to be occupied by a trace. In relevant linguistic texts, the trace may be denoted by a letter t; so the second sentence above may be written:

Traces are considered primarily in Chomskyan transformational grammar and its various developments. They are distinguished from other empty syntactic categories, commonly denoted PRO and pro. More details and examples can be found in the article on empty categories.
