I might have been visiting Mare Island to see the museum and surrounding area but I also got to fit in some wildlife viewing while I was there. I had stepped out of the back of the museum towards one of the dry docks. One of the guys working in a business nearby starting chatting and saying how he wished he had a long lens with him to photograph the ospreys. I could hear a lot of noise but he pointed out the source. All of the high structures around the docks be they cranes or gantries seemed to have a nest on them. Ospreys were all over the place. They had access to the fishing in the water a short distance away so the metalwork was providing a great vantage point with plenty of privacy.
The noise from the nest close to me was pretty loud. A chick was obviously awaiting some food. At first I thought the parents were going to come right in but then I realized that there were so many nests that the birds I could see flying were not necessarily anything to do with this chick. I don’t know whether it had worked that out, though, given the noise it was making when any bird came close. I have no idea how much the nest impact the operation of the machinery and whether there are any restrictions on what can be done when they are in place but they are clearly all over the place.
