Lineolated Parakeets

In the wild, the lineolated parakeet is bright grass-green with fine black barring across the back and wings, a lighter green chest and a few darker tail feathers. In some colors of linnies, male barring appears slightly brighter, while females tend to have less defined markings. However, this is not fully reliable and there are exceptions, so we DNA-sex all babies to accurately determine their sex.

Both sexes of Bourke's parakeets look similar until their first molt, after which they come into full color. The adult male has a blue "crown," while the adult female lacks the blue on the forehead. Additionally, males are known to have more vibrant colors, with a slightly brighter pinkish hue on the chest and face.
