The Urdaibai Bird Center has been cutely styled like an international airport terminal, with multilingual boards marked Arrivals and Departures, and a raised observation platform resembling an air traffic control tower. Through a roof-mounted telescope I watch various avian species landing or taking off from little floating archipelagos on the adjoining lagoon.
I am not a birder so I don’t know what they’re called, though I do recognise the (grey) heron by its pterodactyl flight profile.
