The arrival of birds during the spring migration is like a river going
through its various stages, although in this case one really hopes
for a long-lasting flood stage. At first the new arrivals trickle
in slowly and day-to-day changes in the bird population are hard to
detect. Then, as April progresses, the trickle of migrants changes
to a steady and moderate flow, visible to the keen and astute observer
who keeps both eyes open, watching weather systems and the wind direction.
Chance favors the informed observer. Birds travel literally on
the wind. The position and disposition of frontal systems -
with attendant wind speed, direction and precipitation that might
transport (or ground) migrants - are key pieces of information. Watching
the weather becomes almost as fascinating as trying to predict what
birds will arrive with its passage.
The weather had a bit of everything this past week, with lots of strong
winds from virtually all points on the compass as well as several
passing fronts. With the wild weather, some exceptional birds were
seen. There was also a pulse or wave of migrant land birds that delivered
gaudy and spectacularly marked male rose-breasted grosbeaks to Debbie
Carter at Katama in Edgartown, Whitney and Bill Moody in West Tisbury,
and Charlie Finnerty in Chilmark, all on Saturday, April 23.
A record sighting
The best of the bunch was a seabird seen by David Stanwood of West
Tisbury late in the day on April 20. The wind was howling, so of course
David was out in his 16-foot boat. He was just outside the entrance
to Lake Tashmoo in Vineyard Sound when he was surprised by a small
black and white shearwater that came blasting by. This was a manx
shearwater and this represents the earliest spring date that one has
ever been seen in Massachusetts waters.
The manx shearwater is a small black and white shearwater, a tubenose,
that spends its entire life at sea, coming ashore only to lay a single
egg. Historically, this species was a major rarity in North America
until about 1960. Reports began to increase until they became to be
an almost expected species to find in small numbers during the summer
in Cape Cod Bay. A stunning report of this species breeding on Penikese
Island in Buzzard's Bay came on June 6, 1973, with the discovery of
a nest containing a young bird, by Gus Ben David and Rob Bierregaard.
This provided a first for the western North Atlantic. This is still
the only breeding record for the state.
A special pair
Sally Anderson of West Tisbury had a fantastic finish on April 24.
She was out in her yard at 6 pm and found not one but two, male blue
grosbeaks. These appropriately named birds are a southern species
that breed as far north as southern New Jersey. The species occasionally
appears as spring overshoots when one may appear at someone's feeder
on the Island. However this rarely happens and many spring migrations
there are no reports of these birds at all. To see two males together
in late April is something special. She managed to photograph one
of the grosbeaks as well as a northern parula warbler at the Head
of the Lagoon on April 19.
Birds are on the move everywhere at this season. A winter wren was
seen briefly on April 22 at the Head of the Lagoon by Lanny McDowell
and this writer along with a handful of yellow-rumped warblers, a
dozen white-throated sparrows, a few dark-eyed juncos and a pair of
rough-winged swallows. Great egrets were seen at Felix Neck Wildlife
Sanctuary on April 22 and at the Martha's Vineyard Land Bank's Sepiessa
Preserve in West Tisbury on April 23 and 24. Pine warblers can be
heard singing, Island-wide, in suitable habitat as well as being seen
in favored migrant traps. They are moving north in numbers.
Birds on the water
The waters surrounding the Island have been alive with birdlife as
returning herring and other fish provide food for hungry migrants.
Impressive numbers of northern gannets have been on all sides of the
Vineyard this past week. These large and spectacular birds, which
plunge-dive into the water, create impressive explosions of water
as they hit the water's surface on their way underwater to pursue
scaly prey. Many observers were suitably impressed to call in their
gannet reports to the bird line.
Lanny McDowell and Richard Cohen of West Tisbury were riding the ferry,
exiting outer Vineyard Haven Harbor, early on April 24, in strong
southeast winds and rain when they were surprised by a flock of 30
common terns flying about and fishing in the waters. These early returning
terns were the first to be seen in 2005 in Massachusetts, but surely
not the last. They also were pleased to note five Bonaparte's gulls,
feeding nearby, with black heads in full breeding plumage. Many hundreds
of red-throated loons were noted passing overhead when the front passed
and the wind changed on April 24.
This is the last Thursday in April and the birding will only improve
over upcoming weeks. If you have not paid much attention to birds
in the past, this is a great time to give it a try. You might find
that you like going to beautiful Island locales and looking around
for what there is to see! Until next week - keep your eyes to the
sky!
