BIRDS:
Early Spring fever

This winter has
seemed to be the winter that will not end. It just keeps on coming
despite the rapidly increasing power of the sun (when it is visible).
One thing that I know is true is that it can't continue to be as cold
and snowy and that the annual cycle of life is proceeding - right
on schedule. The calendar indicates that it is March 10 and with a
little fact- checking one can see that the first osprey - the real,
the official Vineyard harbinger of spring (forget the
robin or pinkletink) - is due to return in a little over a week. The
earliest and most fired-up male birds will be returning to favored
traditional nest sites anywhere from March 17 to 21. By April Fool's
Day, the ospreys are back in considerable numbers.
There is something unexplainable, joyful and mysterious, powerful
and life-affirming about that first look at a Vineyard osprey in a
new year, in March, when the trees are bare. While nice to see osprey
in Florida and along the Gulf Coast in winter, these birds don't have
the same home field impact of newly arrived Vineyard birds
in the spring. The Red Sox are playing in Fort Myers and most of the
many resident ospreys in South Florida are already feeding their chicks
in the nest. They have adapted to the climate there and nest much
earlier than their northern brethren for a slew of reasons.
The birds heading for and eventually arriving on the Vineyard are
fascinating. Call them intrepid, spectacular, or raptorial, these
winged fish-eaters have done a lot since leaving here early last fall.
They have navigated large chunks of the Americas, spent the winter
on some Central or South American river or coast, perhaps developing
a fondness for delicious flying fish. Then they rapidly moved back
north, usually by a different route than in the fall. Many have been
island-hopping across the Caribbean or flying across the Gulf of Mexico,
heading north into a still wintry breeding ground to arrive and lay
claim to a nest site. These birds make humans look like slackers.
Osprey tracking
There is a good deal of research being conducted on Vineyard osprey.
Some birds get fitted with satellite tracking receivers, which show
exactly when, how, and where these birds go. The truth is even more
remarkable than what was suspected. There is also a second year of
research about to begin on osprey nest success and what kind of fish
they are catching and bringing to the nest. I'll have much more to
write on this at a later time.
The first osprey sighting of the year is a prestigious achievement.
Not quite like winning the Nobel Prize, but you do get some recognition.
A mention in one or both local papers is almost assured (the joy of
it!). The only caveat is that the bird must be seen by more than one
observer, or photographed. The sighting should be verified by outside
impartial and hopefully sighted other parties and it should be reported
to the bird line pronto. The reason for all this is we have had overzealous
parties in the past attempt to lay claim to the first sighting without
due diligence. Some rather creative observing has gone on and this
we would like to avoid. Good luck and I hope you find the Vineyard's
first osprey of 2005.
Sounds of spring
Change is certainly in the air, especially for those with good hearing.
Bird song is noticeable, increasing and getting louder and more persistent
with each passing day. This is a most welcome development and lets
us hear the change going on around us as well as see it. Mornings
and, to a lesser extent, the period near dusk, are starting to get
noisy after the silence of the winter. Spring really is coming.
Lastly, the waters around the Vineyard are peaking with activity.
Hundreds of thousands of sea ducks as well as a slew of other birds
are on the move. Rafts of eiders and scoters, mind-boggling in number,
are in several favored locales around the Island. Especially surprising
is a huge raft in Vineyard Sound, about a mile or so north of the
Island, which involves approximately 25 thousand eiders. These birds
are not generally here in numbers anything like this.
After the big winds last week on March 3 and 4, an impressive aggregation
of razorbills - football-sized, black-and-white seabirds that are
sort of the northern hemisphere counterpart of penguins (convergent
evolution), and very cute - were found in both Vineyard and Nantucket
Sounds. Flocks of hundreds of razorbills were in outer Vineyard Haven
Harbor and off of East Chop in Oak Bluffs during the day on March
4. There were flocks of razorbills so dense that when they flew off
the water when flushed by a boat they resembled low, smoky clouds.
Many hundreds of razorbills were present, a very impressive sight
indeed from shore.
Until next week - keep your eyes to the sky!
