Birds
Spring Into summer
June
9, 2005
By
E. Vernon Laux
The changing of
the season from spring to summer is always a subtle affair on the
Island. In fact, it has been said that there is no spring along the
New England coastline, with all the cold water retarding vegetative
growth. It seems that winter just slowly relaxes and then it is summer.
Spring being loosely defined as the time when northeast storms,
cold and rainy weather, and generally unpleasant conditions prevail
for three or four days a week should have now come to an end.
That is not to say that the weather wont be cool or that we
are out of the woods as far as storms. For birds, migration is over
and replicating their respective species is the only job at hand for
all species summering here.
As migration slows, often with a last big movement of migrants in
late May and early June, it is hard to miss the incredible dawn
chorus, a daily performance given by nesting land birds. Anywhere
on the Island, away from the immediate shoreline, birds awake before
sunrise and loudly proclaim their existence and temporary occupation
of a particular piece of real estate by singing loudly and often.
It is a remarkable performance best heard if the wind is still, and
with little to no precipitation.
There were lots of migrant birds seen during the last week of May
and in early June. With the spring migration running a bit behind,
many of the farthest north-nesting birds waited to move north. Then,
when conditions are right they make a big last-minute dash to the
finish line, their respective breeding grounds. This includes alder
and yellow-bellied flycatchers, Swainsons and gray-cheeked thrushes,
a variety of spruce and willow-nesting warblers, lingering sea ducks
and loons, and most of the familiar shorebirds lingering on various
tidal flats around the Island excluding oystercatchers, piping plovers,
and willets.
Islanders welcome winged migrants
On May 31, Sally Anderson and Carol Dodd Brush, both of West Tisbury,
did some birding. At the Head of the Lagoon in Oak Bluffs they saw
a black-billed cuckoo and heard a calling yellow-billed cuckoo. Cuckoos,
fabulously named, are odd birds, skulkers that move little,
making them next to invisible while perched, waiting to prey on large
hairy (thorny) caterpillars. This is most unusual in the bird world,
and they are prone to wander in search of caterpillar outbreaks. Cuckoo
distribution varies widely from year to year, as they roam to find
areas that are infested with caterpillars. With the increase in moth
pests, whose larval form are caterpillars, there has been a definite
and noticeable increase in cuckoos on the Cape and Islands the past
couple of years. Much like the locust-eating gulls saved the Mormons
crops, the cuckoos are responding to the outbreak of these incredibly
abundant moth larvae.
Bob Shriber, a seasonal Aquinnah resident, has been birding the past
couple of weekends all over the Island. His best birds have come from
Aquinnah where he heard a Virginia rail calling from a small pond
along Moshup Trail on June 5. He also found a migrant Canada warbler
and noted that a white-eyed vireo appears to be nesting off Church
St. as it was seen and heard calling in the same place 10 days apart.
Nearby there are breeding eastern wood pewees, great crested flycatchers,
red-eyed vireos, American redstarts, black and white warblers, yellow
warblers, common yellowthroats and big numbers of catbirds and eastern
towhees.
Lanny McDowell of West Tisbury was surprised on May 27 by a rare worm-eating
warbler, which was in an apple tree in downtown West Tisbury, and
a rare spring yellow-throated vireo at East Chop on May 29. Both these
birds are inland and southern species, both are always scarce on the
Vineyard. During most spring migrations these species go unrecorded.
There have been three reports for worm-eating and two for yellow-throated
vireos here this spring, making it a banner year for the Vineyard.
Lanny also found a brilliant male blackburnian warbler on May 28.
Take a look in a field guide at this remarkable looking small, striking,
orange, black, and white boreal nesting warbler. At Wasque on Chappaquiddick
on May 29 he watched three parasitic jaegers cruising around, harassing
terns, while looking for the bird mentioned at the end of this column.
Mysterious sightings nearby
After the display of phalaropes and a few storm-petrels during and
after the northeast storm came Memorial Day weekend. With it came
some completely unexpected and outrageous reports from neighboring
areas. On May 27, at the Pilgrim Heights hawk watch in North Truro
on outer Cape Cod, a large mystery swift was seen flying
north. Respected birder and dragonfly guru Blair Nikula of Harwich
observed a large black-colored swift as it flew rapidly by in direct
flight. The bird was impossible to identify, even to specific genus,
as it flew straight and level in typical fast flight. Neither details
of its tail structure or much of anything else was visible, making
it a frustrating but very intriguing sighting.
Lastly, on the late afternoon of May 28 an adult yellow-nosed albatross
was seen flying about Tuckernuck Island by expert birder Dick Veit.
Tuckernuck is a tiny island just to the west of Nantucket and about
11 miles east of the Vineyard. This bird was checking out nesting
gulls. A southern hemisphere species that lives in the south Atlantic
Ocean, a lone member of this species has been seen visiting gull colonies
from May thru early June, for four years in a row from Delaware to
Massachusetts. It seems very likely that this is the same individual,
looking for a mate in the wrong hemisphere. The bird was seen flying
by a seal-watching cruise off Monomoy Island a few days later. It
is just a matter of time before some lucky observer sees this bird
as it cruises by Vineyard shores.
Until next week keep your eyes to the sky!
