Strongest Way To Connect Wood Building An Outdoor Bird Aviary!!!?

Building an outdoor bird aviary!!!? - strongest way to connect wood

I want to build an aviary for my parakeet / s (soon) and asked me what work the best wood and wire, etc.. Also How do I connect the pieces and the wire mesh to do (pop rivet gun, stapler ...) How can I pushing the latch automatically closes behind you and what you can block it. It must meet the test of time and is strong enough for birds and cats can enter or leave.
