In an earlier post (Surprise Tenant 03-27-15) I noted that a pair of Canada geese (Branta canadensis) co-opted an osprey nest high in a ponderosa pine snag before the osprey returned for the season. I wondered what would happen when the osprey came back to claim their nest. The story is now complete. About a week ago I observed the nest for over three hours. Two geese were in the nest and two osprey watched “their” breeding site from a nearby tree. Periodically (about once every 30 to 45 minutes) the osprey would swoop in over the nest. What a cacophony with the osprey and geese both screeching and making distress calls. After watching for a while I decided that the osprey were not interested in attacking (or perhaps they did so before, without success) the geese, instead the osprey appeared to be harassing the geese. The osprey seem to want their nest back, but are not able or willing to actually evict the geese. More tomorrow. . .
