The latter shows the buffy-white spots on the upper primary coverts which serve to distinguish birds of less than one year from the adults. Use of Juvenal Plumage Characters for Age Diagnosis. Upon the acquisition of the first fall or adult plumage, commencing about the eighth week, all of the grayish-buff, brown spotted juvenal plumage is lost except the primary coverts and outer pairs of primaries. The innermost six primary coverts of the juvenal plumage are "clay color," barred and striped with buffy white, in which respect they differ from the fully adult plumage, as shown in Fig. 9. Because these mottled coverts are not lost until the second autumn after hatching, they furnish a reliable indication that birds possessing them are not more than one year old. Birds with mottled coverts breed during their second summer (that is, when one year old) Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
