Welcome to the Dennis Puleston Osprey Fund web site. We invite
you to experience our Web Site as well as the live video and audio
feed from our Osprey Nest Web Cam. Please, join in with
others and submit your observations to our database and check the
conversations on our message board. Sign our guest book and let
us know where you are; we like to know how far we are reaching!
I will give a brief outline of what to expect and when it may happen
at the nest, based on last year’s observations and the input
from our expert sources. Please keep in mind that the timeline
is approximate. Also, please remember that the purpose of the
web cam is to offer to the world an unedited, uncensored look at
what the birds go through during the season. We cannot and
will not intervene in a cycle that has been repeated for thousands
of years.
The adults returned to the nest on March 15, 2004, in the mid
afternoon. They will spend the next couple of weeks courting
and making repairs to the nest. During this time the birds will
often leave the nest vacant, however the male will frequently bring a
gift of fish to the female at the nest. Once the first egg is
laid, in the first or second week of April, the nest will rarely be
without an adult, usually the female who relies on the male to bring
her fish.
The first of the chicks usually will have hatched by mid May, and
once the chicks start to hatch the female will assume almost
exclusive duty at the nest, incubating, feeding and protecting the
chick(s). The male will provide the fish and only occasionally
sit on the eggs/chicks. Last year all four eggs hatched within
seven days of each other.
As the chicks start moving about they begin to compete for the food
provided by the adults. By June they display aggressive
behavior towards each other, with the strongest and most aggressive
getting to eat first while the other(s) must wait. By mid June
the chicks have become very competitive and noisy, often pecking and
shoving each other in the nest. During this period life for
the young chicks is a struggle, and typically some do not survive.
By the end of June the chicks will be stretching their stubby wings
and practicing “takeoffs” by facing into the wind,
flapping their wings and then hopping into the air a few inches.
By early July the adults both leave the nest and chicks for periods
of time, although one can often be heard not far away. During
these times one of the adults will leave a fish in the nest for the
chicks to squabble over. By mid July the chicks will be close
to fledging. They have most of their feathers and spend longer
periods flapping and lifting off from the nest. Last year the
chicks both took their first flight on July 16. By the end of
July the nest is often empty. The chicks and the female return
to feed, however the chicks are big and bold enough to challenge the
female and she occasionally loses her fish. The male brings
fish less and less often, perhaps to encourage the chicks to get
their own.
As the adult birds spend August teaching the chicks how to find and
catch their own meals the nest is empty for longer periods of
time. By the end of August the chicks are about ready to fend
for themselves and return to the nest only to rest for a
while. The migration south is only a few weeks off. By
late September the nest is unused, the migration has
started. Most Ospreys are on their way, although there have
been birds sighted as late as early December.
We hope you enjoy this show of nature!
