Differences between Dutch Blue, Seagreen, and Whiteface Lovebirds.  

Often times, even for experienced breeders it can be difficult to tell between 
these blue mutations.  This combined with dark factors and violet can make 
it an even bigger challenge.


Dutch blue: A creamy colored bib which may have a peachy cast at the edges, 
melon colored brow, and an aqua colored body(no dark factors). (A dutch blue bird 
needs 2 blue genes) 

Seagreen: A white bib which may appear longer than normal, melon colored 
brow, greener aqua colored body, and belly color very much like "seafoam" Crayola 
crayon.  (A seagreen bird has 1 dutch blue gene and 1 Whiteface gene) 

Whiteface: A white bib, optimally a perfectly white brow (although many will 
have a small amount of melon color, ranging from a tint to splotchy), more 
blue aqua color.  (2 whiteface genes are needed to produce a whiteface bird)
