TIOF Nest Monitoring Team Turns 30!

Nest Monitors Rock !!! Happy 30th Birthday!! Those were two of the slides in The International Osprey Foundation’s Kick-off Meeting presentation this January. All volunteers involved in monitoring the osprey nests on Sanibel, Captiva and Fort Myers Beach were invited. This was the Board’s first attempt in many years to gather together all the citizen scientists that help the Foundation gather nesting data locally.  And as it turned out, it was almost thirty years to the day that the first intrepid volunteers began gathering data for the Foundation.


It was early on a Saturday morning, January 13, 1990 to be exact, that a small group of eager osprey enthusiasts gathered for the first ever TIOF Nest Monitor training program. During the training, the observers were instructed in the behaviors that they would be observing during the osprey breeding season.  Exact physical descriptions of gender differences, as well as how to tell adults from juvenile ospreys, were included. All volunteers received a glossary of this information to keep. Significant milestones in the development of the youngsters after mating and incubation, as well as a nesting sequential timeline, were also included.


What followed the training of this little group has been going on now for thirty years, and the program just keeps on growing. (TIOF now boasts almost 50 volunteers.)


It can happen on a Saturday morning after meeting for a cup of coffee together or when the tides are right in the bayou, but teams of TIOF volunteers armed with binoculars, cameras and clipboards continue the work of their predecessors. Bi-weekly visits to hundreds of nests take place for the duration of the osprey breeding season, which usually extends from December through the end of May. By bicycle, car and kayak, the location, nest type/condition and, of course, the behavior of the birds, is carefully documented. Summaries of the nest data have been submitted to the Foundation each spring, and published in our newsletter every year. This year, in addition to these practices, TIOF has joined an international database called Osprey Watch. The data collected from now on will be added to this database which provides important information to The Florida Fish and Wildlife Commission and their counterpoints abroad for consideration when making policy decisions. Our data can also be a big help when CROW needs to re-nest a chick into a foster nest.


While the 2020 season turned out to be more challenging than most, due to Covid-19, the TIOF nest monitors were still able to keep an eye on our favorite raptor’s “goings on.” Seeing all those baby chicks...new life among so much sadness due to the pandemic, was good for the soul,” remarked one nest monitor. And on that we can all agree.

Pedro Lopez, a previous TIOF grant recipient, has provided an excellent video from the environmental organization BIOS CV depicting the cross-fostering of a juvenile osprey in Boa Vista in the Cape Verde Islands. Z24 was severely injured due to sibling aggression by its older and larger nestmates. Brood reduction, mediated by sibling aggression, is quite common in the Boa Vista osprey population. To aid in his survival, the near-fledging Z24, at 7 weeks old, was placed into another nest for a cross-fostering attempt. Typically, cross-fostering is done into nests with other nestlings but this was the first time that a near fledgling osprey had been transferred to a nest without nestlings. Watch the video of the successful cross-fostering of Z24!

The calls started coming to TIOF fast and furious. The issue, a broken nesting pole by the Sanibel Lighthouse that was home to a very popular and productive pair of ospreys. “The birds are back!” While this was great news, the situation wasn’t. The pole was in no shape to support a huge osprey nest. But nobody told the birds that. They started building right away. Beachgoers and Sanibel residents let us know of their concerns. TIOF, along with Ned Bruha, THE WILDLIFE WHISPERER, (our main installer) and Sanibel Fire and Rescue Assistant Chief Chris Jackson started planning the installation. Firefighters Ron Petito and Arian Moore under the direction of Chief Mike Martin, got straight to work removing the nesting materials. Ned wrangled the new platform into place and added back the nesting materials while the birds kept an eye on things from the air. As the sun descended into the western sky, our ospreys re-established residency on the new platform. HOME-SWEET-HOME!
