697SCIENCE sciencemag.org E very day from my work desk, I look upon a boring and uneventful tableau: a cluster of gray and brown buildings, some of them tall; half-filled parking lots; and rooftop duct-work. It is almost unremittingly without consequence, but occasionally, a peregrine falcon slices through it like a gray blade.Books like Gods of the Morning by John Lister-Kaye make the waiting between sightings easier. From his remote, altitudinous home in Scotland, where he operates the Aigas Field Centre, the English naturalist has written a magical book-a poetic celebration of the many different birds that own the wild air around him.For almost 40 years-since the center was opened in 1977-Lister-Kaye has perched with his family at Aigas, watching the seasons change. For decades, the different bird species have arrived and departed again with such cyclical regularity that Lister-Kaye could tell what month it was by their movements. No longer.First, he finds a lonely and diminutive blackcap in September. It had flown into a window and died. The rest of the blackcaps had left already, migrating south to Spain and Italy and warmer temperatures. This one had stayed behind. Twenty-five years earlier, blackcaps themselves had heralded a change in the glen, arriving unexpectedly. Now, Lister-Kaye wonders if they have begun to miss their migratory cues to leave when the weather grows cold.Next, the rooks appeared a full season early in a noisy black tangle to take up their usual nesting spots in the lime trees. Lister-Kaye writes: "What had brought them to my bathroom window, to dance and haggle through the un-leafing tree tops, to soar and plunge and cry among the striping rays of the lowering sun? Just what else was going on?" What follows is Lister-Kaye's year-long rumination on the changes he has seen-and continues to see-and the factors that might be causing them.As the years have passed, Lister-Kaye has watched the waders gradually disappear from the moorland-along with the curlew, the lapwing, the greenshank, and the others. The short-eared owls are gone from the grassland; the hen harriers are gone from the meadow; the oystercatchers are gone from the river.In the prologue, he admits that he had not planned to write this book; instead, he was compelled by the environmental changes he has observed. Wary of blaming what he sees squarely on climate change, Lister-Kaye writes: "But I cannot deny that in the last few years it would appear that the pace of climate change has accelerated and we have entered a period of total weather unpredictability."Lister-Kaye watches the greylag geese pass overhead in V-shaped formation on their way to Iceland to breed. They are a month late. The swallows arrive from Africa a month early. Can the birds handle the changes?In weighty, burnished prose, Lister-Kaye describes it all unflinchingly: the change, the loss, the disruption, the bodies. It is an old man's book. Lister-Kaye, who is 69 years old, is a wise and gentle soul, at one with the land he has lived on for 40 years. His w...
