Owl Tree
By Jim D'Angelo
The tree is clearly the tallest tree around at
least fifty feet in height and eight feet in circumference. It is
a mature Norway spruce maybe a bit past its prime. Its branches are sparse
and open with drooping, needle-covered twigs. On the lower branches the
needles are meagerly distributed, especially on those facing the house. The
tree is very open due to its age and at times looks frail and ailing. It
would seem that its value to wildlife is little. The openness of its branches
lends to little use as cover and nesting habitat, and the few cones it
produces would suggest that as a food source the tree is not good. An ice
storm hit our region this spring breaking branches on every tree in sight.
But the owl tree seemed to faired the best of any tree, only losing one or two
small branches. Every other tree lost large limbs and many branches, the
mature black walnut in the front yard lost about fifteen feet in height and
several limbs. After observing this tree for a few years I started to wonder
what value it holds for wildlife, most of the books and articles I have read
assign value with respect to food produced or cover provided for nesting or
predator avoidance. Clearly this tree is not suited for that. So my quest
begins to find the purpose of this old tree growing in our yard.
December – Moon Shadows
There are many peaceful nights during the winter
months when the moon shines bright and casts shadows across the snow. The
moon-shadow of Owl Tree looks like some strange creature reaching out across
the snow trying to grasp some thing just out of reach, maybe it is trying to
hold onto this peaceful night or reach out to springs warmth? The moon
shadows bring a feeling of peace and calm to winter in stark contrast to the
cold and bleakness we normally conjure up.
January - The Owl Tree Gets its Name
As the days grow colder and all hope of warm
weather is lost to winter’s grip, a great horned owl is whoo-whoo-oo-whoo `ing
in the Norway spruce tree outside our daughter’s bedroom window. No matter
how many times I hear it, I am always amazed that during the coldest part of
the year great horned owls court-mate-nest and incubate their eggs starting a
new generation of life when so many other creatures are fighting for survival
against the cold and snow of a central New York winter. In the morning my
daughter is thrilled that a great horned owl has been just outside her window
and aptly names the tree “the owl tree”. We read Owl Moon by Jane
Yolen and make plans to go on an owl prowl.
February - Shelter from Wind and Weather
Many things in nature that we think to be true
are not always so. Nature always has a way of correcting us. My
interpretation that the Owl Tree is too open to provide cover is a case in
point. Just because the branches are far apart and sparsely covered with
needles does not mean shelter cannot be found when the need is great, and
today the need is great. As a northwest wind pushes and throws snow about,
this day of the coldest month of the year, a dark-eyed junco takes refugee in
the old spruce. It hunkers down as close to a branch as it can and huddles
head first up to the trunk hiding from the biting wind chill. Watching the
bird through the blowing snow makes me feel cold and a bit of guilt for being
inside a nice warm house. The junco with feathers puffed up for insulation
against the cold is etched in my memory; a brief closing of my eyes brings
that moment back through time. A cold blustery day and a determined survivor
seeking refuge were none seemed to be.
March Brings Spring’s First Arrivals
March and April are seasons of change with the
first migrating birds returning from the south and the hold of winter’s grip
broken. The redwing-blackbirds are the first back but shy away from Owl Tree
and instead set up territories in the farm fields surrounding the house. A few
days latter an eastern phoebe grasps a perch on Owl Tree from which to hunt
the season’s insects. Will the phoebe nest underneath one of the old barns
and use the branches of the tree to teach its young how to hunt for insects
like in years past? The hope of spring’s rebirth is all wrapped up in a neat
bundle of feathers fluttering in and out of Owl Tree in search of another
insects.
April’s Fool of Weather
This is the true month when winter’s grip is
broken by spring’s warmth and rain, but winter does not give up easily. One
day can bring sun and temperatures in the 70s and the next a foot or more of
snow. I wonder what phenomenon the Owl Tree has bore witness to? The
chipmunks, which I see only in the spring, dance around the trunk on warm
days. Are they paying homage to this old and wise tree or performing some
sort of spring-dance to ensure the warm weather stays? No, they have other
motivations, but it is fun to think of them with these scenarios in mind. The
chickadees and nuthatches provide the music for the chipmunks on the warm days
with their spring songs, but when winter returns the birds set about scouring
the branches for a hidden insect meal.
May the Warblers Return
May brings the colorful return of forest
wildflowers and the equally vibrant warblers. Yellow-rumped warblers are the
first to return and tonight as our daughter gets ready for bed they are back
in the owl tree. It is hard to believe that there are any insects left in it
after a winter onslaught of downy woodpeckers, black-capped chickadees,
white-breasted nuthatches and several other less common winter visitors. But,
there seems to be a bountiful harvest for the small flock of yellow-rumps as
they spend quite a bit of time searching the branches. If all these birds
have been eating insect and spider off the tree all year long how many are
there living on Owl Tree? The importance of the tree may not be what it
produces but what is produced on it. Its value also is not just for the
birds, but the insect, spiders, lichen and countless other organisms living on
it that we do not see so easily.
June, No Crow Sanctuary
I have been looking for Baltimore orioles since I
saw the first flame shooting across the yard a few weeks ago, but to little
success. How can such a brilliantly colored bird hide so well? This evening
there was a ruckus in a maple tree across from the driveway. At first I
thought, or was hoping, that it was the starlings fledging from the eves
outside our bedroom, but it didn’t sound quite right. Looking and listening a
bit closer, I found a rather large crow sitting on the lower branches of the
maple with a host of smaller birds swooping and diving at it. Several of the
host looked like tongues of fire shooting through the tree, orioles,
accompanied by a few other birds I could not identify as they dove, swooped,
squawked and otherwise harassed the crow. The may lay went on for quite
sometime until the crow left its perch and settled on the ground. As long as
the crow was on the ground the other birds left it alone, but when it returned
to a tree perch other birds immediately and relentlessly harassed it with the
orioles spearheading the effort. This became evident a half hour or so latter
when the crow perched in Owl Tree and was quickly set upon. An oriole and a
kingbird plunged, lunged and shrieked at the crow until it went back down to
the ground and waddled away in peace. Most of the time the crow didn’t seem
to pay any attention to its harassers but every now and then it would snap its
beak as one dove past. The crow would also turn and give a malicious look at
those hounding it as if trying to stare them down like a bully on the
playground. A chipping sparrow came to see what was going on but did not join
in the harassment and kept its distance from the crow. It was probably the
one nesting near by as they have the last two years. The orioles’ aggression
toward the crow’s presents might be related to the failure of an oriole’s nest
last year in the black walnut and what turned out to be a new nest in the
maple.
July Brings the Last Nest
One of the last birds to nest is starting to
gather materials. A pair of cedar waxwings have been collecting dead twigs
from the branches of the Owl Tree and flying away with them to the north. A
few days latter the pair is gathering downy material from a mouse nest I
cleaned out from inside the brush hog. They seem to be taking it to the maple
tree on the other side of the barn. Even though the Owl Tree is not good for
nesting it is good for a nest.
August is the Month of Insect Song
August is another transition month to me with
many hot-hazy-humid days but also many cool foggy nights and mornings, kind of
a harbinger of autumn. The Owl Tree now hosts this year’s generation of
fledglings, bluebirds, flycatchers, nuthatches, woodpeckers, sparrows,
finches, mourning doves and many others. In the morning the dew laden
branches reveal spider or insect webs, like little strands of fog caught by
the tree during the night. These normally invisible webs are now easily seen
with the water droplets affixed to them. Some look like woolly threads
streaming from the tips of branches or a thin layer of cotton candy wrapped
around a branch or twig. The cicadas are buzzing away during the day while
the katydids are churning through the night. This month also has its playful
days; fledgling American robins play their version of tag throughout the
tree. This playful behavior, as we view it, is probably more related to
establishing dominance among the birds than any youthful game. It also
signals an end of summer as the robins are starting to form together in
flocks. The tag playing is an important part of creating order in the flock.
September Brings Us Back to December
The cool nights of September make for good
sleeping weather, but I cannot sleep. Instead I lay awake listening to an
uplifting song coming through the Owl tree and into the house. The eerie
sound of a screech owl is a refreshing and uplifting beacon of nature to me,
much like a call from an old friend. It reconnects me to the spirit of
nature.
Like many aspects of nature there is more to the
owl tree than what there appears to be. If we were to go by the books on
wildlife value the tree would seem to have very little value, but if we go by
the birds and insects and nature itself there is much, much more to this old
tree. I wonder what the next two months will bring!
