Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others. Other risks associated with having blood drawn are slight but may include: 1  Excessive bleeding. 2  Fainting or feeling light-headed. 3  Hematoma (blood accumulating under the skin). 4  Infection (a slight risk any time the skin is broken).
Yellow Quaker or Lutino Quaker This small South American parakeet is a common sight in the United States, both in the home and flying free in urban centers where it has made a home for its wild flock. Gregarious and social, life with a quaker is never dull.
Blue The Blue mutation in Quaker parakeets is quite possibly the simplest to understand. Essentially, this mutation inactivates the production of psittacin resulting in the expression of just the melanin and the structural color creating the blue color. The Blue mutation is an autosomal recessive mutation.ince there is no melanin production, there is no dark pigment to interact with the structural color to create blue, so you are left with the expression of just the psittacin pigments yellow. In Quaker parakeets, there are actually two Lutino mutations.
