Yellow-billed Cuckoo

Yellow-billed Cuckoo
Coccyzus americanus, Linnaeus
Octavo edition, plate 275

“Were I inclined, like many persons who write on Natural History, to criticise the figures given by other students, I should find enough to be censured; but as my object is simply to communicate the result of studies to which I have devoted the greater part of my life, I shall content myself with merely recommending to those intent on the advancement of that most interesting science, to bestow a little more care on their representations of the bills, legs and feet of the species which they bring into notice, and let it be seen that they indeed borrow from nature. From Nature! —How often are these words used, when at a glance he who has seen the perfect and beautiful forms of birds, quadrupeds or other objects, as they have come from the hand of Nature, discovers that the representation is not that of living Nature! But I am deviating from the track which I wish to follow, my desire being simply to give you an opportunity, good reader, of judging for yourself as to the truth of my delineations, and to present you with the results of my observations made in those very woods where the subjects have been found and depicted . . . At this season, they resort to the deepest shades of the forests, and intimate their presence by the frequent repetition of their dull and unmusical notes, which are not unlike those of the young bull-frog. These notes may be represented by the word cow, cow, repeated eight or ten times with increasing rapidity. In fact, from the resemblance of its notes to that word, this Cuckoo is named Cow-bird in nearly every part of the Union. The Dutch farmers of Pennsylvania know it better by the name of Rain Crow, and in Louisiana the French settlers call it Coucou.”
