Three days into an eight-day birding tour in the northwest of Spain, it’s clear to me that steady, sustained birdwatching feels highly meaningful to me. Of course, being chauffeured around and having birds pointed out to you and identified for you by a guide is a different proposition to birding by yourself, but they’re both equally enthralling. For hours you focus your eyes and your mind on the terrain around you, looking for movement and then attempting visual contact and then identification. You’re in nature, as deeply as you’ll ever be. You’re affirming a future for the world, a future you know humankind is messing with. You’re puzzling out, it seems to me, your role in the wider world.
