Abstract | --There were 21 days with observations during 30 January-21 May 1974. Herons were already displaying on January 30, so nesting activity can occur much earlier than has been supposed. A yearling was often seen at the nests, but most nesting activity was by adults. Although eggs were laid in at least one nest, no nest appeared to have been successful. The nesting failure may have resulted from human disturbance. |
