Thanks a lot Candace. Those butterflies are stunning. Honestly, I was considering just taking the butterflies from a garden and putting them into the aviary and then allowing them to reproduce, at which point I would take the eggs out and then allow them to hatch and coccoon away from hungry finches. After they emerged from the chrysalis I would just reintroduce themt to the aviary. As for the pond, I think I am most concerned with the maintenance of it because ponds can lead to molding and what not. So the pond is still 50/50, though I definitely would like it for the aesthetics.
Cindy- thanks again, you've been a big help. The only thing is that my next house will be in Juneau, Alaska, which is quite a bit different from Nevada, and a lot stricter in regards to exotic animals and things. I will call the Department of Agriculture to inquire about it. I really do hope to have a large variety of butterflies in the aviary, same as with the finches I buy. You don't want to have a single species, you want enough colors to capture people's attention.
I also realize that with the different species of butterfly and finch, I am going to have a lot of work cut out for me as far accomodating them all. Some finches prefer to feed on the floor, some like to feed up high. Some like to nest in the low grasses, some like to get as high as they can. I just hope my little aviary will have enough room to bring in all the different types of plants and things that each species is most comfortable with. Obviously with species like Zebra's, you could throw them in a bathroom with some seed and they would be happy. But more exotic types like pintailed parrots or purple grenadiers (which I will most definitely acquire

) have much more specific requirements. I'm not too informed about butterflies, but I was hoping that most do fine with your basic types of flowers. I don't plan on having flowers that are more difficult to care for then the butterflies themselves. I do know that most butterflies are very picky about where they lay their eggs, I am hoping they aren't as picky about where the feed.
