Matt, the birds built the nest overnight.
I hung the basket under the tent frame one day and the next day there was this bird that refused to leave the basket. Mama bird flew away for some reason one time so I took a ladder to check what's in the basket and that is when I took the picture. Maybe the bird just wanted to let me see what's in the basket to say "See? I have an egg up there. Now leave us alone!"
After that, the bird refused to leave the nest and she would just watch me go about my chores around the orchid garden.
