4/24/18 This pair is rebuilding on a site that was active for many years, then they moved across the small bay to another site. The nest was then blown down over winter. It appears they have returned to the old site with a new nest. 5/14/18 One adult low in nest, possibly incubating.

4/20/16 Apparently the pair has stopped nest building and returned to Nest #1465.

This nest had been blown away and site unused for the past three seasons. On April 11, 2016, two birds were at the nest arranging new materials. While I observed, one flew to the lake's edge and returned to the nest with both talons carrying moss.

04/29/15 Nest app;ears to be added to, but no birds ovseved at site. Locals at the area told me they have seen birds at both this site and #1465 at the same tie.

The nest on this structure had fallen a couple of years ago, and I suspect the pair built what has been listed as Nest #1465 as a replacement. But, today a pair was observed at this site and have started rebuilding a nest on the same structure. SO, IS THIS A NEW NEST? Also, a single bird was observed perched by #1465. Will have to sort this ut later.

07/18/12 Although this nest hasbeen reported as abandoned, I observe it as I also see the new nest #1465. Three adults were flying in the area, and one landed on the abandoned nest and stayed on the edge for about five minutes. Nostalgia, perhaps?

6/28 Nest appears abandoned, and no adults in the are. Tyis is the pair (?) that llast year produced four young late in the season.

6/14/12 Made two observations two hours apart. First, at 1030, no activity at the nest although on 5/29 one was in the incubating posture. However, two adults were in the "perch" tree about 200 years away, close together, with one eating a fish, and the other preening. Two hours later, 1230, no activity at or near the nest.
