 156 THE CONDOR Vol. XV air, Otls asio bendirei, our neighborhood pet, quavered a benediction and was duly enrolled as Number m8. In the following list, arranged in the order of Pacific Coast Avifauna Num- ber 8, I have forborne to give scientific names in order not to burden bibliography overmuch nor to try needlessly the patience of our long-suffering editor. Bird- h0rizoning is, confessedly, a "popular" exercise. Its judgments are snap judg- ments, and so are liable to a certain percentage of error. What that percentage may be depends, of course, upon the observer; upon his familiarity xvith field recognition marks, especially bird notes; his knowledge of the locality traversed and its ordinary and accredited bird population; and, most of all, upon his con- scientiousness and general sobriety of judgment. Given such qualifications in any. reasonable degree, and no other fair-minded worker can afford to ignore the testimony of such a list or dispute the value of bird horizons. To do so (and some have done it) [not the editor] is to show the captious and hypercritical spirit which strains out gnats of subspecific inquiry and swallows camels of generic ignorance. In the following list, for .example, I will guarantee the specific validity of every record save Arizona Hooded Oriole (bird not seen and I have not yet had the coveted opportunity to compare the scolding notes of cucullatus nelsoni and bullocki directly), Pied-billed Grebe (bird not well seen), Red-breasted Mergan- ser (female, might have been the rarer americanus), and Herring Gull (flying bird, might have been a bleached example of occidentalis, or a hybrid such as oc- curs off the Washington Coast); and the subspecific validity of all save Califor- nia (?) Yellow Warbler and Pileolated Warbler, both of which were recorded by notes only. There! That clears my conscience. How does it strike yours? To quote or not to quote, that is the question. Oh, by the way, we did have a gun, and we did "take" California Purple Finch and Forster Tern. Next!
