With the
end of the live video stream from the DPOF camera, this
site will transition to an archive of the video and
still pictures recorded over the seven seasons of the
camera's operation. The first three seasons (2003-2005)
are now online. Please follow the
Archive link in the
menu on the left to access the archived material.
The goal is to put all of the video and still images
online and, in addition, to duplicate the archive at the
Cornell Lab of
Ornithology at Cornell University.

The Dennis Puleston Osprey Cam 2003-2009
Dennis Puleston, a
great naturalist and a great friend of the Long Island community,
passed away in 2001. In the 1960s Dennis' study of the declining
osprey population showed that the cause of their dwindling numbers
was a high level of the insecticide DDT in the food chain, causing a
catastrophic thinning of the ospreys' egg shells. With a few
friends, Dennis sued the U.S. government, and began a movement that
resulted in the banning of DDT in the U.S., and in the process
created the nationally known environmental advocacy group, the
Environmental Defense Fund. The osprey
population on Long Island has since thrived.
Upon his death many of
Dennis' friends contributed to a memorial fund — the Dennis
Puleston Osprey Fund — whose purpose was “to encourage
research about ospreys on Long Island, to improve the nesting
opportunities and to educate the public about these magnificent
birds”. With support from the
Post-Morrow Foundation and
technical help from Brookhaven National Laboratory scientists, the
Osprey Cam was created and implemented in March 2003 as a memorial to
Dennis.
A video camera and
stereo microphones were mounted on a steel arm extending above an
osprey nest atop a 38-foot pole near the home of Dennis and his wife
Betty in Brookhaven Hamlet. Buried cables brought video and audio
signals from the nest to a computer in a nearby barn on the Puleston
property. From there, with the help of the local cable company,
Cablevision, the data stream was uploaded to another computer located
at Brookhaven Lab and linked to the internet, providing live
streaming video and sound of everyday life in the osprey nest — 24
hours a day — throughout the annual cycle as these birds courted,
mated, tended their eggs, raised their young, fended off predators,
and finally, after fledging the juvenile birds, left in late summer
on their annual migration. This spectacular view was available to
anyone across the globe with access to the world wide web.
The first year the
camera went live it was one of the very few, if not the only,
wildlife viewing web-cams that had sound, live streaming video, and
still photo capture. The web site's Observation and Message
Boards were open to the public and needed close monitoring since
there were hundreds of questions from the early viewers; Osprey Cam
committee members were kept busy trying to answer them all.
Since we had never before had a view from the camera's perspective,
looking down into the nest, many things were new to us as well.
Trying to keep up with the video clips of interesting observations
and selecting which still shots to save was time consuming and
sometimes tedious, but the clips proved popular. Over time
observers on the web began researching osprey facts and posting them
on the Message Board, many friendships evolved and the regular
visitors called themselves “Featherheads”. People were now
posting their own bird pictures and setting links to their albums.
The Message Board has turned into a sort of chat-room where people
from around the world share their experiences and help each other
with not only osprey data, but many other species and topics as
well. Capturing video from the camera became a tool shared by
anyone who asked how to do it. The online guest book on the
Osprey Cam site garnered entries from virtually every time zone
around the globe, and, with hundreds of observers making entries in
the observation log, every important event has been recorded, season
after season, with notes from eye witnesses.
Fortunately, in each of
the seven years that the Osprey Cam has been operating the nest has
been occupied by a breeding pair, with 2-3 chicks successfully
fledged. Every year the adults (undoubtedly a different pair each
year) arrived at the nest in mid-March, and by early September the
adults and young had left the nest. It is remarkable that the camera
system survived through six seasons, and has remained on the leading
edge of wildlife “cam” technology.
We are pleased to have
been successful pioneers, and recognize that the project cannot
continue indefinitely. At its heart the Osprey Cam is a computer
project, and computer technology typically gets old in a span of
about 18 months. Our camera site, and the group of dedicated
volunteers that maintain it, has had remarkable staying power. In
2008, however, the system was damaged by a lightning strike early in
the nesting season. Not wanting to disturb the birds during the
breeding period, the camera was not removed for repairs until late in
the summer. With a new camera in place, further damage to the system
was found during the 2009 season, the most serious being a fault in
the underground cable from the nest to the barn.
Now, having assessed
the state of our ageing equipment and the increasing likelihood of
further failures, the committee has decided that the season just
completed has been the last for the Osprey Cam. We will continue to
maintain the website, where visitors can interact via the Message
Board, view the observation data and highlight clips from past
seasons, and link to other wildlife viewing sites.
After seven eventful
seasons in which observers from more than a dozen countries,
including many school classrooms, have shared their enthusiasm and
interest for these wonderful birds we feel that the project has
succeeded in its mission, not just for Long Island ospreys, but for
ospreys around the world. It has truly been a fitting memorial to
Dennis.
