Podrobnosti k pozorování
We had an estimated 15 Roseate Terns in the tern colony area with about 30 Arctics and 20 Commons. All three species of tern were seen carrying fish but only Common Tern chicks (at least four) were seen. At least 2 Roseates were carrying fish and courtship behaviours were observed–both on the ground and in the air. I believe most of the prey carried by the terns was sandlance. The Roseates were mostly landing within the tern colony and a few were in the loafing area at the water's edge. We watched Roseates carrying fish on multiple occasions, however, we did not observe them feeding young and no young Roseates were seen in the area at all. Unlike previous recent years, when many second-year/third-year Arctics were seen at Cape Sable, there was only one today. Since most Roseates were not landing at the loafing area near the water, it was difficult to photograph bands, but I did manage to get a few. Note the yellow band with HR6 that I believe is new for NS.
