This is an Australian Cinnamon baby. The colors will richen
after the first molt, but you can see the difference in
coloration between that and the American. This is just a rump
shot with a bad webcam, but you can see the coloration and the
color on the rump. This baby has a single dark factor (lovebird
colorations are confusing), which means the rump is a dark blue.
If your baby has no dark factors the rump will be a light blue
like the bird in the first picture.
I hope this helps!
