Disneynature

Background
Disneynature (also spelled "Disney Nature" in some Disney press releases) is a production banner of Walt Disney Pictures established in 2008 to produce nature documentary films. Its first release was Earth which premiered in cinemas on Earth Day, April 22, 2009, but their logo was first seen in 2008, on their website.

(April 22, 2008- )
Nicknames: "The Iceberg Castle", "The Iceberg Kingdom"

Logo: We see the silhouette of Cinderella/Sleeping Beauty Castle from the current Walt Disney Pictures logo carved into an iceberg, in a polar setting all black. Then, the view becomes lighter as you can clearly see the castle-shaped iceberg. "DiSNEYnature" (in a forest green color, with "DiSNEY" in its signature font) wipes-in.

Variant: In 2018, the words "CELEBRATING 10 YEARS" appear underneath the company name.

FX/SFX: It's all beautiful CGI.

Music/Sounds: Composed by Mark Mancina, who also composed the 2006 Walt Disney Pictures logo, we hear some wind chimes and chanting, then a woodwind fanfare.

Availability: Uncommon. As the name suggests, this banner releases films pertaining to the environment.
 * This logo was first seen on the Disneynature website, and appeared on all of the company's releases since then, such as Penguins and Polar Bear.
 * It's also intact on Hulu's print of March of the Penguins 2: The Next Step (a Disneynature film that they only distributed in France while Hulu distributed it in the United States).

Legacy: This is a very beautiful logo.
