Birds:
Shorebirds of summer, here and there

The last week has been spectacular, not only for the fabulous weather
but also for the numbers of sandpipers and plovers that have arrived,
however briefly, on Island shores. Of the many thousands, indeed tens
of thousands, of individual birds on the move, they are all adults
heading south. The young, left on far northern breeding grounds, congregate
with other immature birds in small flocks, without adult supervision,
and must find their way south thousands and thousands of miles, in
a few weeks, guided only by genetically inherited information in their
small brains. Fascinating stuff, how these small birds manage to fly
from one end of the earth to the other.
These birds are champion long-distance migrants. Imagine, dreaming
while wide awake, flying right alongside with one of these individuals,
traveling at times both day and night in a couple-of-thousand-mile
nonstop leg of the journey, winging over the globe for either the
spring or fall migration, marveling at the flight path and weather
conditions. What these birds do every year gives one pause. Makes
this writer fell like a total slacker compared to them.
Because they are such strong flying, mobile creatures they can, and
do, often turn up on the wrong continent.
This makes these birds even more exciting to birders as some wayward
little shorebird could show up in ones favorite location. In
the past week a couple of Eurasian sandpipers called little stints
have been found on the coast in Chatham for one of few records and
the first of multiple birds of this species in the long ornithological
history of the state. This is less than 30 miles from the Vineyard,
as the stint flies.
Birds on the move
This past weekend Bob Shriber of Aquinnah and Mamaroneck, N.Y. was
pleased with the most shorebirds he had ever encountered at Red Beach,
along the inside of Menemsha Pond on the Aquinnah side. Some 300 semipalmated
sandpipers, a white-rumped sandpiper and a western sandpiper as well
as semipalmated plovers and black-bellied plovers and greater yellowlegs
were feeding on the tidal flats. Nortons Point in Edgartown
was jammed with migrant shorebirds and is worth checking with each
new tide.
The birds are on the move and not waiting for human observers. They
are feeding heavily and frequently at all but the highest tides. The
energy they use powering their flight muscles, which are half their
total weight, is considerable. Under favorable feeding conditions
they can double their body weight in from 10 to 14 days. They then
depart, flying along very fast, burning the fat just like gasoline
in an internal combustion engine. The by-product of metabolizing the
fat, heat and water, are non-polluting end products not like
those of an internal combustion engine.
A cattle egret, a small field-loving heron, spent half of July at
Katama Farm in Edgartown. Lanny McDowell of West Tisbury discovered
it on July 18 and found out from the farm manager that the bird had
been hanging around. There was no indication that the clay-colored
sparrows were still about. Lannys real purpose this day was
to see if last summers famous falcon had made another curtain
call. There was no joy on finding the red-footed falcon,
making last summers individual still the only one of its kind
to have ever been seen in the Americas.
Wayward birds
Vagrant, wayward birds often repeat their earlier mistakes and have
an uncanny way of showing up at the same time and place each year.
I think there is still a 50 percent chance that the falcon may yet
reappear at the same airfield as last year. It was first seen on August
8, 2004 a date that is rapidly approaching. This writer is
keeping his fingers crossed that maybe lightning will strike the same
place twice and the bird will put in an encore appearance. The answer
to this question is almost here.
When its summer the bird line always rings with some off-the-wall
reports. A woman called in on July 20, leaving no phone number or
way to contact her saying, matter-of-factly, that she had just seen
a green kingfisher catch a fish in Oak Bluffs Harbor. She knew the
range was from South Texas south through the Americas, but she calmly
stated that there was one in Oak Bluffs Harbor. Green kingfishers
live in the tropics, are very small, dont migrate, and have
never been seen within 1,500 miles of here. If you read this and see
such a bird please get a picture. There have been several expected
belted kingfishers around the harbor. A green kingfisher would be
most exciting and completely unexpected.
An intriguing report of a possible white-fronted goose came in on
July 24 from Peter O Downey who saw the lone bird on Lake Tashmoo
in Vineyard Haven. He was surprised to find this odd goose and further
confirmation is needed as a variety of domestic goose crosses and
hybrids can look very much like a white-fronted goose. There will
be more news on this when further information and/or photos are available.
Until next week keep your eyes to the sky!
