The juvenile Pied Oystercatcher gives you a glimpse into its development when it stretches a wing out and when it stands close to its parents for size comparison. It will remain with its parents for a few more months and then join a non-breeding flock either to the south or north of Gantheaume Point.

Wood Sandpipers are more common in the north of Australia than the south and they breed in the northern hemisphere with a range that covers from Scandinavia in the west to Siberia and Kamchatka in the east. We observe the Wood Sandpipers come and go each year, but their exact migration route and breeding grounds remains a mystery.

While regular in winter, Pygmy Cormorants do not breed in the vicinity and are absent in spring and summer.

The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding. They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick.
