One question--I've noticed that the windows are unfrosted, do you ever have problems with birds flying into them?
Funny you should mention that. I did have one problem with one bird. I originally just had my 1 white dove, Tricksy, and another flightless (Silky) dove, Stimpy. When I got the sunroom built, I let them out there and there were no problems. Tricksy was somehow "street smart" enough to understand about windows - or so tame she didn't want to go anywhere - and Stimpy of course couldn't fly.
Then I acquired Pecker, a regular fawn Ringneck, from a breeder. He was just a juvenile, not very experienced in the world. I naively placed him on Tricksy's favorite landing area and she immediately chased him off and he went right into a window! Result: broken wing!
So, off to the vet we went! The vet said he could try to fix the wing but he could not guarantee anything. To make a long story short, after $350+ in vet bills (for a $10 bird), Pecker is fine today and can actually fly again. He won't migrate to Panama but he doesn't need to either. He can fly from the floor to a 7 foot high perch and can do laps in the 18 X 20 foot sunroom. He's fathered 7 babies so life is good for him!
I think there is a
risk to let birds fly in the sunroom but the risk is mainly in the first few flights - and the benefits to the birds are so great, it may be worth the risk. Once they get it (about the glass) they never hit it again. It's those first few flights.
So my guidelines for first few flights would be:
1) Know how your birds interact with each other - if there is any aggression or chasing, introduce them to the room one at a time.
2) Do not let untame flighted birds out there - or birds that are likely to scare or spook easily.
3) Put things on the windows - like those stickers to prevent bird strikes or spray them with that XMAS white stuff so the birds know where the glass is.
4) Keep things very calm while the birds are loose in there - especially at first - no other pets or kids playing - just you and the birds, nice and quiet.
5) Have some perches or landing areas at either end of the sunroom so the birds have a destination inside the sunroom. If it's completely empty, they may think "oh I'll just fly over and land on that tree over there..." and smack! So get some ficus trees or similar for
inside the sunroom so they can fly to those.
I have to say, once you get past all this, having a sunroom for my birds is like heaven. I have it filled with potted plants and have a white plastic table and chairs in there. I like to sit out there with my birds for hours. They enjoy flying and exploring in there. I even play a tape of amazon jungle birds when they are loose - it's like my refuge from the world. I can let me doves and parakeets out in there at the same time - they all love flying around and all visit me (land on me) and enjoy eating from my hands or from food I put on the table. And I don't need to mark the windows with stickers or XMAS stuff anymore - the birds know where they are and avoid them.
I have several cages of finches in there too:
A couple other thing's I'll mention.
1) None of my birds has ever gotten sick eating any of the tropical plants in my sunroom. They seem to know that they should only eat what greens I give them in their cages - or else, they tested the plants and found them bad tasting and never bother with them again. The doves however, sometimes find nesting material and bring it back to their cages.
2) I did have an instance where my doves started sitting on the ceiling fan blades. So now I turn the fan on very slow, when the birds are out, and they do not go up there any more - but I got them used to the fan rotations while they were in their cages so they are not afraid of it either.
3) Hawks
outside your sunroom can be a problem - making your birds freak out. I think they present the biggest danger of bird window crashes aside from the first few flights. All I can say is my birds have learned to deal with it and have not flown into anything - but they do seem spooked if a hawk is outside.
4) All my doves and parakeets have learned (on their own) to fly back to their own cages - which is very nice! Actually, even when the finches get out by accident, they are usually back in their cages within 15 minutes! I just leave the room so as not to spook them and they go right back in.
