A plover's tale

The sandy beaches of Victoria's Southwest are prime recreational spaces that attract beach and water lovers from far and wide. They also offer some of the best coastal habitat in Victoria and are home to several bird species, including the rare hooded plover [Thinornis rubricollis].
These shy little birds can be seen nesting from September to April. The pair occupies a small territory on dry sand at the top of the beach. Here the hen lays several eggs in a shallow scrape. Because of the exposed nature of the nest site, parents, chicks and eggs are well camouflaged and very difficult to see. But once spotted, their behaviour is intriguing. The parent birds will distract intruders that venture too close to their territory. They run up and down the beach, feign foraging or a broken wing, then dart away at the last moment.
Although protecting them from natural predators, many of the bird’s habits make them vulnerable to human disturbance. While the parents put on their acts, eggs and chicks are left unguarded at the mercy of marauding gulls, the sun’s heat, wind and trampling. Dogs off leash account for many deaths. Activities like horse riding and off-road vehicle use cause havoc.
In recent years, signs and temporary barriers have appeared on the beaches as volunteers attempt to protect the vulnerable nest sites. Sometimes little wooden chick shelters are placed on the sand for them to hide in. This not only makes these feisty birds easier to locate and observe, but improves their rate of successful breeding.
Unfortunately, this attempt to aid the birds has attracted unwanted attention. A deranged surfer lurks between Warrnambool and Killarney, removing barriers and burning signs and chick shelters. He is even suspected of removing eggs. It is little wonder that none of the sites he vandalises has produced successful fledglings this season.
With the Victorian hooded plover population estimated at around 600, one wonders how long we will have the opportunity to see this bird on our beaches. Increased awareness of these and other beach nesting birds, and finding simple ways to share the beach without being a threat to these species [like keeping dogs leashed on nesting beaches] will significantly improve their chances of survival.

The trouble is, many people see these kinds of measures as an inconvenience or a threat to personal liberty. After all, the beach is there solely for our benefit, isn't it?
