A Northwoods Almanac for 6/13 – 26, 2014
White
Pelicans!
On 5/25, Elizabeth Stone on Trout Lake saw six white
pelicans on Trout Lake.
And on 6/1, Chuck Schlindwein observed 17 white pelicans on Buckskin Lake
south of Lac du Flambeau.
The sighting of white
pelicans still draws great surprise from most Wisconsin residents, but white
pelicans have been nesting in Wisconsin since 1994, when two pairs were found
nesting on Cat Island in the bay of Green Bay. The nests failed, but in 1995, nine
pairs nested, with 35 birds present throughout the summer. After that, it was “Katie
bar the door.” The year 2013 marked the twentieth consecutive year white
pelicans nested on Cat Island, and 1,065 nests were documented on 5/24.
In 2003, some breeding
pelicans from Cat Island spilled over onto nearby Lone Tree Island, and in
2013, 1,088 nesting pairs were documented, more than on Cat Island!
The pelicans didn’t nest
only in Green Bay. They spread south into Horicon Marsh where the first
breeding pelicans were documented in 1999. They also began breeding on several
dredge spoil islands on Lake Butte des Morts in 2005, on Pancake Island in Lake
Puckaway in 2007, on two islands on Lake Winnebago in 2007, and on an island in
Beaver Dam Lake in 2011.
All told in 2013, 4,123
nesting pairs of white pelicans were documented at eight colony sites in
Wisconsin.
What makes this all the
more interesting is that no conclusive evidence exists that white pelicans ever
nested in the state historically.
So, where did they come
from? And why? These western breeding birds (Minnesota supports some 22,000
breeding pairs) began an eastern expansion two decades ago apparently due to
agricultural reclamation of their breeding marshes and water diversion
projects, as well as periodic predation events. Also, major colony abandonment
occurred for unknown reasons in 2005 at the Chase Lake National Wildlife Refuge
in North Dakota, the largest breeding colony in North America (over 35,000
pelicans in 2000!), with thousands of pelicans leaving to nest elsewhere.
Whatever the reasons for
their eastern movement, the bottom line is that white pelicans are still
steadily increasing in Wisconsin, with colonies expected to expand onto the
Wisconsin side of the Mississippi River and onto Lake Superior.
So, for now, our area
remains a minor stopover site for white pelicans on their migratory journeys.
But soon I expect we’ll be seeing many more of these magnificent birds whose
9-foot wingspans rival those of the California condor.
Other Sightings
5/26: Eastern gray tree
frogs began calling in Manitowish.
5/27: Thousands
of cottongrass plants flowered in Powell Marsh, making it appear as if it had
snowed.
5/27: Cedar
waxwings arrived in Manitowish and immediately began eating the flower petals
on our plum trees. Waxwings usually are the last of the migrants to arrive in
any given spring.
5/28: American
elm trees dropped their seeds, an event Mary and I had never taken notice of
before. We were sitting on our deck (pre-mosquito hatch!) and a rain of these
seeds was coming down from our two elm trees.
5/29/14: Sharon Drawz saw a moose crossing Hwy. 51, about two miles south
of Manitowish.
5/31: Lilacs bloomed in Manitowish.
Yellow Scum!
Nope,
this isn’t about your cowardly evil neighbor, but rather this: That yellow film
currently so prevalent on the surface of puddles and ponds is the male pollen
from pine trees. Pines produce prodigious clouds of pollen that are borne on
the wind and often collect wherever there is calm water. The pollen grains are
a mere four one-hundred-thousandths of an inch in length, requiring a scanning
electron microscope for study. They’re worth studying, too, because they’re
virtually indestructible and form “microfossils,” which persist for literally millions
of years at the bottom of lakes and ponds. Thus, a pollen specialist (a
“palynologist”) can identify the species of trees that once lived in a region
by studying their lake sediments, and by doing so, then tease out how regional
climates varied over centuries and millennia.
As
for the tiny immature female pine cones, their scales are slightly separated
and contain a small amount of fluid secreted by the plant. When pollen sifts
down between the scales and comes to rest on the fluid, the pollen is then
drawn into the cone until it comes into contact with the ovules at the bottom
of each cone scale. And voila! The cone is fertilized, and the scales grow
thicker until they press together and firmly close the cone. In the case of
white pine, the cone eventually grows to eight inches long and opens a year and
a half later in the fall, shedding its winged seeds. In jack pines, the cones
can remain tightly closed for as many as 20 years or more with the seeds
remaining viable, until a fire comes through and the heat induces the cones to
open.
Babies
Nesting season is here, which often leads to encounters with
baby birds and other wildlife. But unless clearly injured or orphaned, a baby
wild animal's best chance for survival is with its parents. Wisconsin DNR
offers a handy key to determining how to best help a baby bird at: http://1.usa.gov/TB0xK0. The agency also provides a rehabilitation directory and
general species guidance at: http://1.usa.gov/1kL0KVg
Celestial Events
Jupiter
continues to be visible in the evening night sky. Early in the month it
sets about three hours after sunset, but by month’s end, it sets an hour after
sunset. Look for the giant planet, shining at a brilliant - 2.0 magnitude,
below Castor and Pollux, the twin stars of Gemini. Four of its larger moons
should also be easily seen through high-powered binoculars and small telescopes
– we use our 20x bird spotting scope.
Mars,
shining at magnitude -1.2, is also visible in the evening sky in
the constellation Virgo, along with Saturn, which can be found in the
constellation Libra low in the southeast. Venus is also still visible low in
the eastern sky, but at pre-dawn.
The
full moon occurs on 6/13. It was called the “Full Strawberry Moon” by nearly
every Algonquin tribe because of the relatively short harvesting season
for strawberries in mid-June.
The Lyrids Meteor Shower occurs on 6/15, but will be
pretty much washed out by the nearly full moon.
Summer Solstice
June
21 marks the summer solstice and the first “official” day of the summer
season. The sun will reach its highest elevation in the northern hemisphere’s
noontime sky, and at this point, it “pauses” before beginning its
southward trip, lowering its noontime elevation each day until it reaches its
lowest altitude in December at the Winter Solstice.
The
word “solstice” is derived from two Latin words “sol”(sun) and “stitium” (to
stop), reflecting the pause in the northward movement at noon. Today generally marks
the longest daylight period and shortest night here at the mid-latitudes.
Many
still incorrectly equate our warmer summertime temperatures with our distance
from the sun. The truth is our seasonal
temperature changes are caused by the earth's axial tilt, not our distance from
the sun. We are actually at our greatest distance from the sun in July,
some 3 million miles more distant than in January.
Mosquitoes!
They, which shall not be
named, have reached Biblical proportions. But one of Mary’s friends said, “I
don’t care. I’m just so happy to be up here. I’ll just wear a head net or bug
dope until their numbers go down.”
Perhaps that’s the attitude we all need to take.
No
One Ever Washed a Rental Car
Harvard’s president, Lawrence
Summers, once said, “In the history of the world, no one has ever washed a
rented car.”
I’m
taken by this statement, because it so clearly shows the need for ownership to
help people act with conservation in mind. A person
who owns something has a strong incentive to take care of it.
But what happens when there’s
no ownership and you’re responsible only for some small aspect of the company
you work for, or the property you’re camping on, or the two square feet of the
right wing of a plane you helped build? The issue is that only whole planes
fly, companies succeed best when everyone buys in, and public lands are treated
with the most care when everyone assumes ownership.
The
question then is how can people be encouraged to take care of things they don’t
actually own? How does one come to a sense
of ownership?
It’s
worth noting, however, that ownership doesn’t automatically instill care.
Sometimes ownership creates a “what’s mine is mine” and cavalier attitude that
one can do whatever one wants and no one can say otherwise. Ownership can lead
to the attitude that my little piece of the pie is more important the all
others, whatever the impact on anyone or anything else.
We’ve
got lots of important issues in the Northwoods that require all of us to assume
ownership, but an ownership that assumes no privilege over any other owners. We
can’t be renters who assume no responsibility, but we also can’t be owners that
grab on to their piece and growl.
Whatever
the cause, whatever the issue, we’re called upon to honor the whole, all of its
parts, and all of its processes. Until then, we’re still just renting the car.
