Thanks Michael. The Fairy Martin breeding colony in the culvert under
Weeroona Drive, Wamboin, at -35.246599, 149.338315, is much the same as
other years.
Tree Martins have almost disappeared from my Woodland Survey site near
Tharwa despite little change to the vegetation. Two decades ago they
were breeding residents there. Now rarely seen.
