New breeding project: Troupial - Icterus icterus

Little over a month ago, I acquired a female Troupial.  After little over a week of letting the pair see each other from separate cage, I let them live together in a small aviary (4ft x 2ft x 6ft) for now and plan to build a similar white-rumped shama size aviary for them at the end of this year.  They live in harmony so far but do not act like a bond pair.  Male and female are never stay close together.  The male is dominant and sometimes attempt to bite the female when she comes near to him.  They love crickets, mealworms, superworms, banana, papaya, and anything that is sweet, soft, and orange/red color.
There is not much information on breeding this specie beside some basic information that I can find on internet:  http://en.wikipedia.org/wiki/Troupial
