I always notice how the birds pick that exact twig angle, like a tiny natural hinge. They’ve been doing it for ages, so if you can mimic that subtle balance, the house will feel right to them. Adding your own precision can help if you’re worried about extreme weather, but just don’t make it feel too mechanical—birds like a little natural feel. And keep an eye out for moss creeping in cracks; it can be a silent threat. Just let the design stay simple and let the critters decide what’s best.
