Before the month of June was very old,
I realized that this was going to be a good summer to get well
acquainted with woodpeckers. Upon moving into the Annie Spring trailer
court, the family of Seasonal Ranger J. Francis Stine informed me of
recent activity by a male Arctic three-toed woodpecker, Picoides
arcticus (Swainson), at his roosting hole in the center of the
campground. This hole was located about twelve feet up in a live
lodgepole pine. It was easily recognized as belonging to this bird
because of the recent stripping of bark, forming a band about eighteen
inches wide and nearly encircling the tree, at the same height as the
hole. Only the male was seen, and he was usually gone all day.
Late in the morning of June 11, I
waited for about an hour to see if there was any daytime activity, as I
was hoping that this might be a nesting hole. The male finally came,
pecking at the bark for two or three minutes before flying away again.
No nesting there. I did hear and, after sneaking up the hill above the
nest, see him giving the rapid, loud drumming on a dead branch of a tree
which is usually associated with mating interests. This is the only
record I have been able to find of a roosting hole in the park, and
there is only one definite record of a nesting hole.
Soon after locating this hole, the high
chatter of another woodpecker attracted my attention to a nesting hole
located about thirty feet up in the dead, bleached-out snag of what
seemed to be another lodgepole pine. The tree was standing within ten
feet of the South Entrance road just across from the trailer court
driveway. The bright red splotch of color on the top of this bird's head
quickly identified him as a hairy woodpecker, presumably Dendrocopus
villosus orius (Oberholser). It was apparently a nesting hole, but
because of the unstableness of the tree I had to be satisfied with
climbing an adjacent tree about eight feet away for observation and
pictures.
After a long and uncomfortable wait,
the male accommodated me by flying to the nest. On two occasions I saw
the male chase away an inquisitive red-breasted nuthatch, Sitta
canadensis L., which may also have wanted a nesting hole. Many days
later, and after many observations of the hole and the active male, I
saw the female for the first time. Her appearance seemed to coincide
with the first peeping of the newly-hatched young, about June 20.
Although I wasn't privileged to see all the family out of the nest at
once, I took pictures of a nearly-grown male almost out of the hole on
July 12, and from the noise within I would guess there were at least two
other young. By July 19 there was no sign of the family at or near the
hole.
June 17 I will long remember as the day
I saw my first western pileated woodpecker, Dryocopus pileatus
picinus (Bangs). This crow-sized, black bird with brilliant red
crest and black-and-white striped neck swooped across the front of my
car about four miles inside the park on the South Entrance road. He
displayed his beauty while perched for a minute on a tree and then
hurried away, giving his characteristic, loud, laughing cackle.
The very next day, while down in Annie
Creek canyon near the South Entrance, I saw my first red-breasted
sapsucker, Sphyrapicus varius dagetti Grinnell, very active about
the mountain ash, Sorbus sitchensis M. Roem., and the black
cottonwood, Populus trichocarpa Torr. and Gray. Upon revisiting
this locality a month later, both parents were dividing their attention
between feeding two immature birds -- quite capable of flying around by
themselves -- and drinking the sap or eating the insects attracted by
the sap oozing from the characteristic rows of square holes which they
had pecked in the bark of the mountain ash. The young were also
concentrating on pecking the ooze, so much so that I could approach
within a few feet.
A momentary distraction from
woodpeckers was occasioned by the loud peeping of an immature water
ouzel or American dipper, Cinclus mexicanus unicolor Bonaparte,
who was also being fed, on a log in midstream. He could hardly constrain
himself when one of the parents would fly up bringing some insect
tidbit.
In this same locality I noticed a pair
of red-shafted flickers,
Colaptes cafer (Gmelin), another member of the woodpecker family.
Since they were on the other side of the stream I couldn't check into
their reason for favoring that particular area. They are the most
conspicuous, if not the most abundant, woodpecker in the park,
especially in the lower regions. On July 28, while escorting a field
trip near the top of Garfield Peak Trail, I spotted one showing a
brighter red than I had noticed before. On July 21 I saw a young flicker
taking food from a parent about six miles inside the south boundary.
While exploring Wizard Island for a few hours on August 6, I noticed
what appeared to be a family group flying among the trees.
In order to round out my woodpecker
experiences, I was eager to observe the fairly common Williamson
sapsucker, Sphyrapicus thyroideus (Cassin), which is rather
unusual in having a conspicuous contrast in color markings between the
male and female. It was especially gratifying, then, to discover on July
12 a nesting hole containing young about forty feet up in a dead
mountain hemlock near the Wineglass on the northeastern side of the
lake. Both parents were in the feeding business and were quite disturbed
when I scrambled up to look in the hole, even though I couldn't see the
young.
The Lewis woodpecker, Asyndesmus
lewis (Gray), is also fairly abundant in the park, especially late
in the summer. Last year I noticed them first on August 31, traveling in
small flocks near Garfield Peak. They were evidently attracted to the
area by flying insects or ripening berries. Such post-breeding movements
to higher areas are common here.
Other woodpeckers uncommonly observed
in the park are the alpine three-toed woodpecker, Picoides
tridactylus (L.), the white-headed woodpecker, Dendrocopos
albolarvatus (Cassin), and the red-naped sapsucker, Sphyrapicus
varius nuchalis Baird.
Learning to recognize the members of a
specific bird family and getting acquainted with their habits make a
commonplace walk through the woods an adventure. Concentrating on the
woodpeckers has guided my observations, and wherever I go I find a
"family friend." Now, even old snags, instead of seeming dubiously
attractive, are noticed and suggest a potential home or a source of food
for an unusual bird.
Perhaps you would like to choose a
particular group of birds to concentrate your attention upon for a
while. Here in Crater Lake National Park, Dr. Donald S. Farner's The
Birds of Crater Lake
should prove an interesting and useful companion for your bird
explorations.
