Many people ask why it is important to monitor these Osprey nests. This is a labor of love, driven by passion, to learn more about these magnificent birds of prey. They are an indicator species and therefore their status reveals much about the health of our environment. Because Ospreys eat primarily fish for their entire lifetime, they are vulnerable to chemicals that are present in the water and ...can accumulate in their bodies. Any drop in their productivity can be a red flag to us, and therefore their population needs to be monitored carefully. The productivity dropped last year so its important to follow up this year to see if this is a trend. Of course there are normal ups and downs to their productivity, but it is the long term trends that we are interested in.
Eagles are monitored quite carefully and blood samples analyzed, but they eat things other than fish so may not be as affected by contaminants as Ospreys are.  Since Ospreys are a large bird that nests in the open, they are fairly easy to monitor, so I am hoping to continue this work and find interested people to assist with this research.
 I remember years ago meeting with Harrison "Bud" Tordoff, the well known University professor who was so instrumental in the Peregrine project. He urged us to monitor and band as many Osprey nests as we possibly could, for as long as we possibly could, as long as there were people willing to do this work. He pointed out that we cannot always know what we are researching for, but if we continued to collect the data, in hindsight it might be extremely valuable. I am trying, Bud!
