Poetic license

In the first chapter of the The Particular Sadness of Lemon Cake, by Aimee Bender, a quite fine novel, this passage stopped me:

My father usually agreed with [my mother’s] requests, because stamped in his two-footed stance and jaw was the word Provider, and he loved her the way a bird-watcher’s heart leaps when he hears the call of the roseate spoonbill, a fluffy pink wader, calling its lilting coo-coo from the mangroves. Check, says the bird-watcher. Sure, said my father, tapping a handful of mail against her back. (p. 5)

Now Ajaia ajaja is indeed a spectacular bird to see, and she’s got the habitat right, but waders as a rule don’t have much of a voice. But (thought I), since I hadn’t heard the birds I saw in Florida some years ago, maybe the spoonbill does have a pleasant coo. Not so, says Roger Peterson (eastern North America field guide, 5/e): “VOICE: About nesting colony, a low grunting croak.” David Sibley adds, “Also a fairly rapid, dry, rasping, rrek-ek-ek-ek-ek-ek, much lower, faster than ibises.” The one available audio sample from the Macaulay Library confirms.
