May Nest List & Definitions

Warwick, May 2019 Photo by Claire G.

Hello Monitors!

Thank you all for a great first couple of months. We know it has been a bit crazy with the new system, forms and such, but here we are knee-deep in another season! Following is a status report of your hard work through May 9th.

While reviewing all of the observations, including field notes, we noticed that some of the terms are not being used on a consistent basis. In order to capture accurate data that can be compared across previous decades of observations, we all need to be using the same definitions for what we observe in the field.

Please review the following definitions. If you are confused, please send us an email. It is very important that our collective reporting is consistent.

· No Nest = There is no structure or nest at the location

· Historic Nest = A nest that has not been Active in a few years. There may, or may not, be a nest or structure. (So far this season, three nests previously labeled as Historic have shown activity!) The label of “Historic” is determined at the end of each year.

· Breeding Activity = One of more of the following: Nest building, copulation, incubation, male providing food to nest and leaving, female feeding chicks, nestlings, fledglings

· Not Active = No Breeding Activity (see above) was observed. Osprey may have been present at or near the nest, however no breeding activity was witnessed during the observation period.

· Active = One or more elements of Breeding Activity (see above) was observed. In this program the term “Active” does not mean Osprey were present at the nest. Some element of Breeding Activity must have been observed to call the nest “Active”. This can seem a little counter-intuitive.

· Unknown = You could not figure out what you were observing. Please use this term sparingly and explain in the notes box.

· Successful = Fledglings (not nestlings) were observed in the nest. One or more nestlings in a nest may not live to become a fledgling. Fledglings have flight feathers and their wing muscles are developed enough to make them capable of flight. Fledglings may still rely on their parents for food.

· Number of Fledglings = The number of fledglings actually observed in the nest. This figure may vary from observation to observation.

Through your hard work there are 334 nests in the database. While a total of 212 nests have been classified as either Active, Not Active or having No Nest, there are still 89 nests that have not been reported upon. These nests have been highlighted in yellow. It would be great if you could look at the highlighted nests and try to report on one or two of them.

· Total nests in database:334

· Historic nests (Grey): 38 (3 of which are now Active)

· Needing observation / monitor (Yellow): 89

· Active Nests: 124

· Not Active Nests: 56

· No Nests: 32

· Unknown Nests: 6

Thank you again for all of your hard work. The data in this list will be updated and presented again in early June. If you see any errors or omissions please send a note to us at rhodeislandosprey@gmail.com.

See you on the trails,

Jon, Jess and Gary
