Dear
Journey North,
Over
the last couple of weeks many days with strong
southerly winds have brought warm temperatures to the southern
prairies of Canada. The warmth has melted the last bits of snow
from winter. The southerly winds brought
warm
temperatures,
and also the first Whooping Cranes into Canada. The first confirmed
sighting
was on April 11 near the Last Mountain Lake National Wildlife
Area. Since then, Whooping Cranes have been seen all
across the agricultural
portion of their migration route from near Odessa in southeastern
Saskatchewan all the way to Debden in Central Saskatchewan. All
that is left for some of the pairs is to cross the boreal forested
areas of northern Saskatchewan and Alberta before settling back
onto their summer home in the northeastern corner of Wood Buffalo
National Park. The park is just west of the town of Fort
Smith, Northwest Territories.
The Female Who Lost Her Mate
As
you know, one of our banded males (red-Yellow) was found
dead in North Dakota on April 18. He has been paired with
the same female
since 1986. They have brought 7 young to the Texas wintering
grounds over the years. Soon I will be looking over his former territory,
adjacent to the Sass
River, to see if I can find his mate. She is also banded
(White-Red) but now only retains the aluminum band. By
the time I find her she is likely to have found
a new mate. But she is not likely
to nest this year. Because she's an older female,
it is likely that her new mate will be much younger
than her, and she may bring him to the territory that she and her
old mate established so many years ago. It is unfortunate that
we have lost
him. But the female's change in mates will give us an opportunity
to learn more information on re-pairing and subsequent nesting.
A Favorite Bird
The
surviving female is an older bird, and you may be surprised
to know that her dad is still alive! He is one of our oldest
known cranes and he is
one
of
my favorite
birds.
This
old bird is
known as the Lobstick male. He was banded
as a youngster in 1978. Over the years he has lost all
his bands. But he still continues to
use the
same nesting territory along Lobstick Creek that he has used
since 1982. His mate has no bands, so we do not know
how old she is or
how long she has been his mate. White-Red, who is their daughter,
was also their first chick. White-Red's dad (the Lobstick male)
will be 29 years
old this June. The Lobstick pair is one of the first pairs that
I
see during my spring surveys on the breeding grounds.
They also
stop at the same location about an hour’s drive from
my house each fall. I am really looking forward to seeing
these birds
and
all the cranes again over the next few weeks.
