Sad day . Shortly after 4am , a Barking Owl swooped out of the gloom and grabbed the Curlew chick in the photograph . The previous morning , shortly after five, the parents had been shrieking , indicating that they were under attack , without anything sighted . The chick was big for its age and was the only one that had hatched from two eggs . Two fully grown Curlews are peering through the front door of the Little Darwin den wanting to be fed .
