Ornithological Notes Of Interest
By Staff
Farallon Cormorant:
Thus far this summer (August 10, 1948) there has been only a single
Cormorant reported from Crater Lake. On August 7, 1948, one was seen in
flight near Cloudcap, apparently from the surface of the lake. Mr. Paul
Herron, who operates the launch in a daily trip around the lake, had not
seen Cormorants previously this year. No Cormorants were seen on Crater
Lake in 1946. According to Mr. Herron and Dr. Ruth Hopson, there were
none during the summer of 1947. This is in striking contrast to the
summers of 1939, 1940, and 1941 when daily a group of ten or more of
these fish eaters could be seen on the Phantom Ship. It is of interest
to note that in 1939, 1940 and 1941 fish were abundant in Crater Lake,
whereas in 1946, 1947 and 1947 fish were relatively scarce and fishing
was poor.
Long-legged Birds:
Rare in the park, a white egret was seen stalking a quiet pool in Annie
Creek near the South Entrance on August 31, 1947, while a blue heron was
observed winging its way down the middle fork of Annie Creek the
following day.
Western Crow:
Although the Western Crow quite likely appears from time to time within
the limits of the park, there seems to be no actual record of such up to
this time. On June 24, 1948, one was seen in flight over Munson meadows,
and on July 2, 1948 two more were seen, one along Annie Creek Canyon
about two miles below Annie Spring and another along the highway between
Annie Spring and Park Headquarters. In view of the fact that crows and
ravens rarely occur commonly together in an area, and that ravens are
relatively common, the sparsity of crows in the park is
understandable.
Sierra Creeper:
On November 30, 1947, four feet of snow covered the ground at Park
Headquarters. It was cupped to the ground around the bases of trees near
the Administration Building. From the depths of one of these issued a
familiar, though unexpected, note of high pitch. And then, seemingly
quite at home in a red fir in spite of the cold, appeared a little
Sierra creeper. These birds reside in fir forests in the park in summer
and are known to winter around Fort Klamath but this appears to be the
only winter record inside the park.
Rock Wren:
Usually a common denizen of the talus slopes, disintegrating outcrops,
and other similar areas where its energetic, distinctive trills blend
into a unique pattern of sound with the acute whistle of the marmot and
plaintive cry of the coney, the Rock Wren has been conspicuously absent
during the summer of 1948. Not a single record has been reported from
the entire park. In no previous year in which records have been kept has
there been this complete absence of the species.
Townsend's Solitaire:
Although this inauspicious songster has little in its doleful, ashy
plumage to suggest its true familial affiliation, an instant of its
heterogeneously rich song immediately identifies it with the other
thrushes. The sight of this inconspicuous thrush with its white outer
tail feathers and buffy wing spots, as it flutters gracefully to the
ground to obtain an insect and returns to perch is not frequent in
Crater Lake National Park. More frequently the male is to be seen, and
heard, from the apex of a bare stub, often a hundred feet from the
ground. It is almost paradoxical that the occupant of so lofty a song
perch should nest on the ground; but such is almost invariably the case.
On July 1, 1948, a nest with four downy young was found in an
unprotected place on the ground on the west bank of Sand Creek. Only a
single parent was observed to be caring for the young. This appears to
be the first recorded observation of the nesting of this species in the
park.
Short-tailed Chickadee:
Chickadees are the abundant acrobatic light percussioneers of the
evergreen symphony. In autumn particularly, their unmusical
vocalizations are warmly welcome to the ears of the ornithologists for
they frequently constitute the nucleus of conglomerate flocks of Juncos,
Chickadees, Chipping Sparrows, Warblers, and other species which wander
through the coniferous forests during this season. Despite the ubiquity
and abundance of these clamorous tits, our knowledge of the nesting
habits of this species in Crater Lake National Park is amazingly sparse.
During the course of the summer of 1948 three nests have been observed.
On July 7 a pair was noted to be attending a nest in the utility
building in the lower residential area at Park Headquarters. By July 12
food was being carried to the nest by both parents, indicating that
young were being fed rather than food being carried to an incubating
adult. On July 26 a nest was discovered in a dead Mountain Hemlock near
the stone quarry; both parents were carrying food. On July 22 a nest was
found in a dead Lodgepole Pine at the Junction of the Red Cone Motorway
with the North Entrance Highway. These observations, and those of
previous years, would indicate that nesting by this species in Crater
Lake National Park must being in mid-June.
Slender-billed Nuthatch:
The insect and larva eating habits of this species and its more abundant
and boisterous smaller relative, the Red-breasted Nuthatch, are of
profound significance in the ecology of our coniferous forests. Together
with certain of the Woodpeckers, the Chickadees, and the Creepers, the
Nuthatches persistently depredate the populations of insects which
frequent the barks of trees. Together with certain parasitic wasps and
fungi these birds constitute the only natural control of many species of
destructive insects. Prior to 1948 the Slender-billed Nuthatch had been
regarded as a rare species of the higher altitudes whose breeding status
was unknown. On July 12, 1948 a pair was found carrying food to a nest
near the junction of the Crater Peak Motorway and the Rim Drive. Unlike
the smaller Red-breasted Nuthatch which is sometimes noisy in the
vicinity of the nest, these birds were completely silent.
Washington Lilies
By Dr. G. C. Ruhle, Park Naturalist
Queen of American lilies is the real Washington Lily (Lilium
washingtonianum), which grows in comparatively dry stands of brush
in the arid Transition Zone from the Columbia River southward through
the Sierras. Growing three to six feet tall, it bears clusters of a
half-dozen or dozen very fragrant flowers that are white upon opening
but turn first to pink, then to rose with age.
On the sunny manzanita-covered slopes of Copeland Ridge west of the
lake at an elevation of 5500 feet, these lilies presented a superb
display this year. Though frequently peering high above the red-boughed
manzanita, some lower plants could be discovered by their sweet scent
before they were detected by the eye.
