Many touching accounts of specific raptors here— a blind Golden Eagle, a young Osprey in difficulty catching fish until she catches a Bluefish too heavy for her— but also of successful birds. Young osprey migrate thousands of miles, starting days before their parents do, those in Wales migrating to Africa, the males to the western continent, females more central or eastern. Literally inhuman, instinctual. Takes two years for them to return, if they do. Fairly high mortality of raptor young…Eagles among the highest, 90% of their young not surviving their first year.
Dunne’s intimate account of specific birds builds on his knowledge of plumage and molting. “The flight and tail feathers of young raptors…are commonly longer than those of adults, a structural advantage that partially compensates for a younger bird’s lack of aerial finesse”(31).
Thirty-three different species, each with its own chapter. I started with my most familiar: Osprey (81 nests on my Westport River, MA), Eagle (one nest for five years until the tree blew over a couple years ago), Cooper’s Hawk (nest next door), Sharp-Shinned Hawk (coursing below the treetops, dining on our feeder birds, sometimes), Red-Tailed Hawk (call commonly imitated by Blue Jays), and…oh, not in this book, but the little Screech Owl who loves the taste of Mourning Doves. Such an owl was living in a Wood Duck house one March when I imitated its call to two Mourning Doves on a wire. They flew off faster than I thought they could. Once at a talk on my book, Birdtalk, I said “Mourning Doves have the same misfortune pigs have, the misfortune of being delicious.”
These predator species are all reverse dimorphic, with the females larger than the males, often about a third, the Peregrines, but up to twice as large in Cooper’s Hawks. Not clear why females are larger, possibly to enable defense of their nest and nestlings agains raccoons and crows. Or even, Dunne suggests, the “infanticidal inclinations of males”(66).[I do recall at the Swanery in Abbotsbury, Dorset UK, where medieval monks raised Swans for meat, now the female Swans have to protect their young, in crowded yard and a half square nest and water, from their mates.]
Even in Dunne’s least enthused chapter, on Turkey Vultures, he rises to a well-phrased last passage—a relief, since I consider these birds arguably the most beautiful fliers, quartering and circling on updrafts. Dunne puts it this way, “On its perch, there is something humble [and shaggy] about a Turkey Vulture, but in the air, it is a thing transformed…it turned and pirouetted in the sky, its wings flashed silver”(26).
