Wasaga Beach Provincial Park Piping Plover volunteer coordinator Laurie Kassabian said the presence of eight Piping Plovers have been confirmed at the main beach.
Two pair of Plovers have nested and the first egg was confirmed May 14.
The nesting area, located along the boardwalk at Beach Area One, is fenced. Once there are four eggs in each nest, a cage called an exclosure will be placed around the nest to stop predators from getting the eggs yet allowing the birds to move in and out freely.
The beach has become a regular nesting ground for the endangered migratory Piping Plover.
They were spotted in Wasaga Beach in 2005 after a more than 70-year absence. The birds have been coming every year since, arriving in the early spring.
Piping Plovers are short and stocky and often mistaken for Killdeer or Semipalmated Plovers. They can be found on open sand or among sparse vegetation. Their backs are the colour of dry sand with a single black band on the neck and brow and they have black-tipped orange beaks and orange legs.
The park had let the point naturalize, hoping to attract the birds. Leaving the beach in its natural state provides the finicky bird the perfect place to nest.
The efforts began at Sleeping Bear Dunes National Lakeshore on Lake Michigan where the birds are being identified and tracked.
The birds winter in the Gulf of Mexico and fly north to nest.
In 1985, when the Piping Plover was declared an endangered species by the Committee on the Status of Endangered Wildlife in Canada, there were only 17 breeding pairs. Conservation efforts have brought that number up to about 50 pairs.
A group of volunteers referred to as guardians keep watch over the nesting area to inform passersby of their presence and keep people and dogs out of the fenced area.
