Errrrrrrrm i could be wrong but i dont believe *PINE is good because of the toxins in the pitch...not sure what you mean about
**paper trees...if you mean Birch its the same with them..they also have a sappy resin type of pitch just like pine.
Above is a site which list quite a few that are ok and not ok..altho im sure its not a complete list.
I left my cockies outside here in the northeast of massachusetts to temps. at 50degrees an slightly lower with no harmful affects.
They were also outside during nite an storms...However, i did have a drop down of light weight melmar i think its called which was on hinges and just folded on top of the roof when not needed and then dropped on three sides...one on the lake side of the aviary which was the length and two on the ends...and hooked with hook and eye...
i didnt have my floor on the ground tho i had it raised off the ground about 3 1/2 feet and used more of the melmar to cover the flooring inside which made for real easy hose clean up. With the flooring being that and the drop downs it pretty much kept the worst of the storms out an wind also..as i too had my aviary close to the house, so that side didnt need protection and still let the air flow even with the sides down. I got the melmar from hardware and lumber store and just asked for slightly damaged which they usually throw out anyway and got it at a steal of a price. Again it made for super easy clean...a quick hosing which the birds enjoyed too when i did it and i would have to in the beginning hold it high on mist and they would fly thru the mist like kids in a puddle...once they got their bath giggle then they would perch and id just hose off the flooring. I set up the inside doorway so it was a slider...the outside door opened like a regular door and was like a hallway type of thing so when i got to the raised portion of the aviary, the sliding door allowed a full reach inside and with a extendable window squigee washer for tough areas it was a breeze to clean up...if any of that makes sense and you can visualize it.
I also used natural wood perches with some manzinita..or what was then called iron wood. Mine cost more than yours tho maybe because of the lobster wire and the special clips we used to secure it to the 2x4's...what are your dimensions to your aviary...mine was large because i used it as a mixed breeder flight for my cockatiels. Then loved it and it was so nice seeing them so free and content. The only wild bird i had a problem with and that was just once...as it learned its lesson quick banging into the lobster wire was a nite owl. It tried one strike an that was all she wrote giggle...the birds never flinched which shocked me...i think maybe cuz it happened so quick.
The most hardship the wild ones suffer is looking for water and food in the different seasons...it gets hot there but not so they also couldnt fly to keep cool and find shade.
Again thanks for the videos and thanks for reminding me of how much joy a outdoor aviary can be.
