Indian Blue Black Shoulder (IBBS)
Nigripen
Ala Negra

*Please click on images to enlarge
COLOR:
Blue is the natural, unmutated color of the Indian peafowl, also known as the wild type (aka the type found in the wild).

CONTENTS:
This page contains photos of blues with the blackshoulder pattern mutations (wild type color, blackshoulder pattern).

PATTERN DESCRIPTION:
Blackshoulder is a colored bird with solid color replacing the barred color on the wing for males. Females will be mostly white, with color flecked over their main body, a rust band around their necks, rusty color on top of their heads, and a solid-color tail. Blue blackshoulders have a black tail and dark to black flecking.

Blackshoulder birds of all colors are born looking nearly white, with very pale tan flight feathers. As the birds mature, speckling and marbling appears on the new feathers of each molt. By around 3 months of age, males will begin to develop solid saddle feathers with paler "arrows" in the center of each feather. Females will begin to speckle out.

GENETICS:
Blackshoulder is a single-expression autosomal recessive gene for pattern.

NOTES:
Blackshoulder is a bit of a misnomer, as the gene only causes a black shoulder in a wild type bird. In truth, it causes a solid wing instead of a barred wing pattern, leading some to refer to this as "solid wing." Blackshoulder and solid wing are the same mutation by different names, just as "barred wing" and "wild wing" both refer to the wild type wing pattern.
