TIL two things:
1. YouTube is home to the world's only heavy metal-themed talk show. It's called Two Minutes to Late Night.
2. Vocalists of all metal subgenres often shriek and squawk like birds. To prove it, the Two Minutes to Late Night host recently asked ornithologist Tom Stephenson of BirdGenie (an app that identifies birds by their sounds), "What Birds Do Metal Singers Sound Like?" He had no problem matching birds to their metal equivalent.
For instance, the (most-non-metal) bird expert (ever) identified the Northern Potoo as a close match to the screeching vocals of Converge's 2001 metalcore song "Concubine." Ok, sure.

Late last month, a woman in Alabaster, Alabama spotted an unusual bird in her backyard feeder, which was soon revealed to be an extremely rare yellow-pigmented Northern cardinal.
Auburn University biology professor Geoffrey Hill said the cardinal in the photos is an adult male in the same species as the common red cardinal, but carries a genetic mutation that causes what would normally be brilliant red feathers to be bright yellow instead.
Alabaster resident Charlie Stephenson first noticed the unusual bird at her backyard feeder in late January and posted about it on Facebook. She said she's been birding for decades but it took her some time to figure out what she was seeing.
"I thought 'well there's a bird I've never seen before'," Stephenson said. "Then I realized it was a cardinal, and it was a yellow cardinal."
... Hill -- who has literally written books on bird coloration -- said the mutation is rare enough that even he, as a bird curator and researcher has never seen one in person.
"There are probably a million bird feeding stations in that area so very very roughly, yellow cardinals are a one in a million mutation."
However, an expert at the National Audubon Society has a different theory on why the bird's plumage is yellow:

As Geoff LeBaron, Audubon’s Christmas Bird Count director, points out, the cardinal’s crest and wing feathers look frayed in photos. While wear and tear is a natural part of a bird’s life, it can be exacerbated by a poor diet or environmental stressors.

Here's a diagram that shows the relative size of a great grey owl's body to its feathers. It's hosted on Wikimedia commons, labelled "Cross sectioned taxidermied Great Grey Owl, Strix nebulosa, showing the extent of the body plumage, Zoological Museum, Copenhagen."
