Other Activity: Can now confirm two ospreys are back! Both on the nest this evening. Been hearing the female had joined the male in the last day or two but hadn’t seen them together. By comparing photos it very much appears this is the same pair as the last years. Happy and relieved to see them! They have been building up the nest and there’s a bunch of white fabric hanging on one side that has been making it difficult to see what’s in the nest but this was 100 percent both ospreys landing on the nest within seconds of each other and staying.
