Blue and green quaker parrots are actually the same species, known as the quaker parrot or Monk parakeet (Myiopsitta monachus). The difference between the two lies in their coloration, which is a result of genetic variation and selective breeding.
Blue quakers, as their name suggests, have a blue coloration. This blue color is caused by a mutation in their genes that affects the production of a pigment called psittacin. Psittacin is responsible for the green coloration in most quakers, so the lack or reduced amount of this pigment in blue quakers results in their distinct blue appearance.
It’s important to note that the extent of blue coloration can vary among individual blue quakers. Some may have a deep blue hue, while others may appear more turquoise or even have patches of green on their plumage. This is due to different levels of psittacin production in their genetic makeup.
Green quaker parrots, on the other hand, have the typical green coloration associated with quakers. Their plumage is predominantly green, with shades ranging from bright lime green to a darker, more olive green. This green color is the result of normal psittacin production.
When it comes to physical characteristics and behavior, blue and green quakers are virtually identical. Both have a similar size, with an average length of about 12 inches (30 cm). They have stocky bodies, short tails, and a distinctive feathered face. Their beak is strong and hooked, allowing them to crack open nuts and seeds, which form a significant part of their diet in the wild.
In terms of behavior, quaker parrots are known for their intelligence and social nature. They are highly vocal birds, capable of mimicking human speech and various sounds they encounter in their environment. Quakers are also known for their playful and curious nature, making them popular pets among bird enthusiasts.
While blue quakers may have a different coloration, they are not considered a separate species from the green quakers. The genetic variation that causes the blue color is simply a result of selective breeding and different levels of psittacin production. This variation adds to the diversity within the quaker parrot species and makes blue quakers an appealing choice for those who appreciate their unique beauty.
