Birds
By Don C. Fisher, Park Ranger
A list of birds seen in the park has
been kept and added to from time to time as a new bird appeared in the
park area until last year the number of birds seen in the park was
seventy-six. Already this year a stranger has been added to the list.
The latest addition being the Mourning Dove (Zenaidura macroura).
The dove is essentially a bird of the fields and how they have drifted
into wooded areas of the park is a question that is both interesting and
surprising.
Members of the various crews have
reported many nests of the Ruffed grouse (Bonasa umbellus) and
also the Sooty grouse (Dendragapus obscurus) more commonly known
as the Blue Grouse.
Perhaps the most unlucky of the forest
residents of the park is a pair of Mountain Robins who have resided at
Annie Spring for a number of years. They have selected a tree near the
spring for the site of their nest and each year have reared their brood.
Last summer one of the rangers on duty heard the birds making a great
commotion and walked over to the tree. The birds were all a flutter and
would hop from limb to limb and then swoop down at something that the
ranger could not see. Finally the ranger began to climb the tree and
just as he reached the nest a frightened pine squirrel scampered down
the tree and away to another clump of trees. Several times afterward the
squirrel was soon going or coming from the nest.
This spring the two birds, undaunted by
the tragedy of last summer, returned and again took up their home in the
same tree. All went well until one morning a great noise arose in the
vicinity of the nest and on examination the ranger found that a large
raven had settled near the nest and was attacked by the robins who
forced it to leave but, however, no sooner did the parent birds return
to the nest than the raven swooped down to the nest and seemingly
unmindful of the robins, robbed the nest and departed. Thus the law of
nature takes its course and the rangers wonder if the robins will return
again next spring.
Of the seventy-six birds known to
inhabit the park, only five care to stay here the year round. During the
summer months the woodlands ring with the songs of the feathered
inhabitants but when the old man winter comes creeping into the trees
most of the songsters depart for lower elevations.
The five who are here all winter are
Stellar Jay, (Cyanocitta stelleri), Oregon Jay (Perisoreous
obscurus), Raven (Corvus corax)), Clarks Crow (Nucifraga
columbiana), and the Red-breasted Nuthatch (Sitta canadensis).
In the spring the first of the migrants
to return are Pine Siskin
(Spinus pinus), Western Robin (Planestincus Migratorius
propinquus), Mountain Blue Bird (Sialia currucoides), and the
Oregon Junco (Junco oreganus).
