These delightfully engaging birds have been known to nest in a particular tree for a quarter of a century, and again they may select a different site every year. Though I have no evidence in confirmation of the theory, I am inclined to think that arboreal snakes are influential in causing changes. Although the domed nests must be difficult for even a snake to enter so large a congregation of noisy birds would inevitably attract these slim nocturnal marauders. Moreover, a case may be cited in support of the theory. In a Moreton Bay ash (EUCALYPTUS TESSELARIS), not far from this spot, there nested a pair of white-headed sea eagles, a pair of cockatoos, and a colony of metallic starlings, four or five hundred strong. The memory of man knows not the first settlement of this amicable community, which remained until during temporary absence the blacks were suborned to climb the tree to secure the eggs of the eagle. They also helped themselves to a few of the callow starlings. The sea eagles and cockatoos discarded the tree forthwith, and the starlings in a couple of years. And why? Because, in my opinion at least, the eagles had policed the tree, killing offhand any green or grey snake which had the stupidity to sneak among the nests. When the policemen went to another beat the snakes took to frightening the unprotected birds and to the burgling of their nest. This incident caused a revision of the protective laws. They are much more explicit, and the pains and penalties for the violation of them are now absolutely unholy in their truculence. During the 1909 season a serious diminution was noted in the number of metallic starlings and nutmeg pigeons. In the case of the former I am at a loss to account for the cause of the comparatively few visitors--always highly esteemed and admired and preserved from interference--except on the theory of the outbreak of an epidemic or in the possible fact that they are falling victims to the feminine passion for fine feathers. The Grouse Disease Commission has found a recognised period in the fluctuations of the number of those game birds. During a cycle of sixty years there recur the good year, the very good year, the record year, the bad disease year, the recovery, the average, and the good average. The round is said to be almost invariable. So may it be with the metallic starling.
