Over the echoing Skype line my parents mention seeing a northern harrier on the outskirts of Ottawa. Perched on a post as they drove along, it had leaned into the air to sail off across the fields, a pearl-gray ghost slipping away. Still speaking, I pull The Sibley Guide to the Birds of Eastern North America from the bookcase beside me. I leaf backwards through the waders and rails, overshooting the raptors to land amidst ducks and geese before paging my way forward to find the harrier. I then press the illustration up to the webcam, trying my best to keep it steady. “That’s the one,” says my father, smiling back at me on the screen.
