.--In the summer of 1963 at the Round Lake Waterfowl Station, Rrund
Lake, Minnesota, I observed and painted from life four newly-hatched downy young
of the Spectacled Eider. The birds were hatched (28 June, 1 bird; 6 July, 3 birds),
after artificial incubation, from eggs collected at Igiak Bay, Alaska, by Glen Smart,
resident biologist at the station. I measured the birds at 24 hours of age, then placed
them in an observation pen for several days. The correctness of all sketches and notes
was tested against the live bird in the hand.
The four birds were large-headed, heavily-built ducklings with strong, muscular legs.
The crown, back, wings, and tail were dark grayish brown; the wing-linings were
light grayish brown; the face, chin, and lower cheeks were light to pale pinkish smoke
gray; the breast was smoke gray, becoming lighter and grayer toward the tail.
Superimposed upon the light face color was a large disc-like patch of smooth grayish-
brown down, completely surrounding the eye and leaving only a narrow circle of the
light color between it and the dark color of the crown. The brown patch, not the
light color, formed the major part of the "spectacle" of the downy young (Figure 1).
There was an irregular wash of light grayish brown in the auricular region. The
culmen was feathered to a point even with or slightly beyond the rear edge of the
nostril; these feathers had a silvery cast. The bill was light, opaque grayish blue,
straight-sided, with a brownish-red nail; the egg tooth was creamy white to pinkish
yellow; the iris was dark brown; the tongue and the lining of the mouth were dull,
pale pink; the feet were dark umber gray, lighter on the sides of the toes.
These observations differed widely from most published accounts of this species in
two respects: bill color and the description of the "spectacle." Regarding bill color,
the only description which agreed with mine, and, apparently, the only one based
on live young, appears on p. 351 of Herbert Brandifs Alaska bird trails (Cleveland,
Ohio, Bird Research Foundation, 1943), where the bill is described as pale blue.
Other descriptions and illustrations are incorrect in this respect.
In the matter of the "spectacle," the only correct account of its character that I
have found appears in Dementiev, Gladkov et al. Birds o/ the Soviet Union (Moscow,
Soviet Acad. Sci., 1951-1954, 6 vols.), vol. 4, p. 540. I quote here a translation:
"Around the eyes [are] brown spots in place o/ /uture spectacles [emphasis mine]
and on this background behind the eyes [is a] dark wash." I found Benifs description
(U.S. Natl. Mus., Bull. 130, pp. 76-77, 1925) ambiguous, because relative areas of
color are not given nor is the relation of the dark-colored "spectacle" of the downy
young to the light-colored "spectacle" of the adult mentioned. Other descriptions are
incorrect, at least for downies of less than two weeks of age.
From two to four weeks of age, there is a gradual molt of the down feathers,
including those of the "spectacle." An examination of three downies at Round Lake
which died at the beginning of the molt period showed that replacement of the
brown "spectacle" by light golden buff contour feathers was irregular, leaving various
streaks and patches of smooth dark down around and behind the eye. Since I have
found no published illustration which shows correctly the brown "spectacle" of the
young downy, but rather illustrations by Peter Scott (pl. 11 in Delacour, The water-
/owl o/ the world, London, Country Life Ltd., vol. 3, 1959), Allan Brooks (pl. 80
in Phillips, A natural history o/ the ducks, vol. 4, 1926), and T. M. Shortt (pl. 34 in
Kortright, The ducks, geese, and swans o/North America, Washington, D.C., Amer.
Wildlife Inst., 1943) which show a sort of dark "question mark" around and behind

the eye, I suggest that the specimens from which these artists worked were probably
already in molt. Furthermore, it is conceivable that the molting "spectacle" would
take on an even more linear appearance in a dried specimen, and the artist, faithful to
his eye, could justifiably interpret this as a narrow circle or "question mark."
Only one of the four Spectacled Eiders survived at Round Lake. I observed this
bird frequently, and found that at four weeks of age, it was almost completely
feathered (largely chestnut brown, barred with black) and the "spectacle" had become
entirely light, golden buff. The bill was still light grayish blue, but was duller in
tone, lacking the shine and freshness of color of the downies' bills; the feet had lost
their shiny dark scutes and had become light bluish gray with nearly black webs and
joints.
From these observations as well as from published descriptions, I have concluded
that the "spectacle" is present in the same form in the downy young as it is in juvenal
and adult Spectacled Eiders, and furthermore, that previous descriptions and illustra-
tions of a "question mark" and postorbital streak around the eye of the downy
young represent not the true "spectacle," but rather a stage in the molt from natal
down to juvenal plumage.
In early behavioral characteristics, of which I can find no published description,
these young eiders walked nearly erect, with heads held a little down and forward,
giving them a long-legged, flat-bellied appearance suggestive of a pugilist heading for
his adversary. Generally quiet, they occasionally gave a single call note, a peculiar,
clear, flat-sounding, Geep!, low in pitch, without discernible overtones. In distress,
the call became Geep-eep! or Geep-eep-eep-eepl, rapidly repeated, the second and
subsequent syllables rising in pitch to a major third above the first syllable.
The eiders "sat" a good deal during their first two days, usually resting on the
belly, but sometimes on the heels, with backs nearly upright and breasts high, the
bills touching the puffed-up breasts and the heads drawn back. Sometimes they would
stand, legs far apart and backs upright, heads drawn backward at a near-impossible
angle, waggling their bills from side to side in what I took to be a form of preening.
Figure 2 shows these various attitudes. In temperament, the birds were neither ag-
gressive nor overly docile, but seemed to be quite self-contained, whether with birds
of their own or other species.

I was assisted by grants from the Frank M. Chapman Memorial Fund of the
American Museum of Natural History (1962-1963) and from the Society of the
Sigma Xi (1963). The material was gathered at the Round Lake Waterfowl Station,
Round Lake, Minnesota, owned and operated by Kenneth L. Sather. Through the
efforts of Mr. Sather and Glen Smart, with the cooperation of the U.S. Fish and
Wildlife Service, the eggs of the Spectacled Eider were obtained from Alaska. I
thank Mr. Sather for use of the excellent facilities of his station. Thanks go also to
Kenneth C. Parkes and H. A. Hochbaum for their prompt and helpful suggestions in
the preparation of this note, and to Miss Gladys Sudomlak for her translation of the
Russian work. The entire project of which this work was a part is being carried on
with the cooperation of the Delta Waterfowl Research Station, Delta, Manitoba,
Canada.--Co;; HLcso Nm;so, c/o Carl R. Nelson, Jr., School o/ Architecture,
