On my ramble today, just off the "mail road" I came across a pair of curlews and while I was making a few photographs I noticed a chick in the grass. He/she was about 6" high and its bill was only about 2" long. I never got closer than about 50'. So they've already hatched, some time ago, or at least this little guy had. And strangely, these parents were not very aggressive toward me. I wonder if they calm down once the babies are hatched.
