stick

I have birdies that visit me each day and now that winter is coming I want to offer them a nest to rest in. They aren't parrots, they're little birds but you guys are nice so help me. What do I use to stick the wooden nest to the plastic frame or something? oh and I don't keep the nest...

Ok. Started stick training with sunflower seeds. First 2 days, awesome!! Then last night she touched the stick, I clicked the clicker, gave her a treat and she nicked my finger and flew on the floor. Yesterday, I did the stick training through the cage (yes, I'm terrified she will bite me)...
