From this spot in the Little Darwin backyard , a Curlew egg disappeared overnight. Not long after the loss of the latest chick , plump, active and adventurous, its parents again displayed signs of being broody and soon another egg was produced . Now it has vanished, a slight moisture patch visible . Was it a snake , a rat ? Suddenly, a Curlew which seems to know its way about the backyard has appeared and we wonder if it was one of two chicks which survived and flew away . A strange visitor to the back door was the large flying insect below with exceedingly long legs .
