Thanks once again to John and Sue O'Malley for providing the images seen here.
John writes: "I think this one is a younger bird as markings are not as strong as the other 2 birds. Yes! Sue and I observed that we have had three birds (maybe a family) feeding quietly in the drainage area to the left as you drive over the main bridge at Kingston."
The area John refers to is the wetland seen in this overview of the Kingston and Arthurs Vale Historic Area (KAVHA). This part of the island was recently added to the World Heritage List recognising the immaculately conserved Colonial Georgian architecture of the buildings that remain from the penal colony period covering the late 1700s to the mid 1850s when convicts were deported to the island from England. The ephemeral wetlands provide a source of interest that changes daily as birds rest there during their long flights from the Arctic Circle to New Zealand.
