Pappa is as excited as kids on an Easter Egg hunt. He can't wait to be the first on the balcony every evening - often before the sun has set. As soon as he lands on the railing, he begins an animated mating call. Pappa's white spot on his throat balloons out as he punctuates the early evening with his excited calls. He stands close to the far nest pot and looks in - as if expecting something to be there, or to happen, when he does.
We've seen this behaviour before. The pre-mating / breeding season excitement building. Before long, we will see more of Pot Plant Owl in the immediate area. Pappa will do the hunting for them both, while Pot Plant Owl remains close to the nest, expending as little energy as possible.
