PIPING PLOVER NEST WITH FOUR BEAUTIFUL EGGS AND MANY THANKS TO ESSEX GREENBELT’S DAVE RIMMER AND FIONA HILL FOR INSTALLING THE WIRE EXCLOSURE!

The Piping Plovers have a nest and it is not in the parking lot! Four beautiful, perfect eggs are now being tended to by both Mama and Papa Plover on the beach, in the same general location as the 2016 and 2017 nest locations.

Early this morning, Essex Greenbelt’s Dave Rimmer, assisted by intern Fionna Hill, installed the wire exclosure that helps protect the Piping Plover eggs from canid, avian, and human disturbance and destruction.

Dave is permitted by Mass Wildlife, and is an expert in, building and installing PiPl wire exclosures. Dave and Fionna constructed the exclosure together outside the nesting area so that when they actually had to step into the nesting area to place the exclosure there was minimal disturbance to the nest. Dave noted that it only took the two of them about fifteen minutes to install the wire structure around the nest, and Papa Plover was back sitting on the nest within one minute of completion.

Gloucester’s conservation agent Adrienne Lennon was present at the onset, but had to tend to issues related to the dyke construction at Goose Cove. Dave’s new assistant, Fiona Hill, will be helping to monitor the Plovers for the summer. She grew up in Newburyport and is a a junior at UMass Amherst. Welcome to Good Harbor Beach Fiona and we look forward to working with you!

So sorry the photos are very much on the pink side. I should convert the whole batch to black and white. My darling granddaughter was playing with my camera over the weekend and all the settings were messed up–the photos from the Cape Ann Museum were taken with the white balance set to underwater, and the beach photos this morning set to nine on the red scale! At least now I know how to fix it if it happens again 🙂

OUR GOOD HARBOR BEACH KILLDEER PLOVER CHICKS!

You may recall that several weeks back we posted a photo of a Killdeer nest with four eggs. I only discovered the nest because each and every time anyone walked past, a Killdeer would call shrilly and drag its wings through the dunes in a dramatic display of “broken wing” trickery. I would often play along and see how far away the Killdeer would take me until one morning I decided to see what it was they were hiding.

Killdeer Broken Wing Distraction Display

Off to the side of the path that leads to the beach, not more than six feet away, was a loose scrape of dirt and sticks, with four perfect Killdeer eggs!

I had no idea when they had been laid, so there was no way of knowing when the chicks would hatch. Each morning on my way to check on the Piping Plovers I’d take a peak, until one day there weren’t any. How sad I thought, and wondered if a predator had eaten the eggs. But the nest had not been disturbed and there were no broken egg shells. A mystery.

The following morning I checked on the Piping Plover nest in the parking lot. It was drizzly but there were two Killdeers near to where the PiPl exclosure is located. I sat in my car watching the adult Killdeers when to my delight and amazement, out tumbled four teeny chicks from under Mama Killdeer. A car makes the perfect blind and for quite some time I photographed and filmed the Killdeer family.

Off and on during that rainy day I stopped by to check on the Killdeers. Because of the weather, the parking lot was virtually empty. Tiny tufted black, brown, and white feather balls atop overly long spindly legs, the baby birds spent all their time zooming here and there, foraging on itsy bitty insects in the grass and gravel.

When not foraging, they would run under Mom or Dad to warm up on that damp drizzly day. Just like Piping Plover chicks, Killdeer chicks are precocial birds and can feed themselves within hours after hatching however, because they are so tiny, they lose body heat relatively quickly. The chicks need the warmth provided by snuggling under Mom and Dad.

The next morning it was still drizzling, and the Killdeer family was still in the same location! I watched them for a bit, when a man showed up with his dog. The Killdeer parents went into high alert and did their best distraction displays. The dog chased the adult Killdeers around the parking lot while I spoke with the man. It is the same man who brings his dog to Good Harbor Beach via the footbridge end at the close of the day, after the lifeguards and dog officers have left. This was a tremendous problem last year after the Piping Plovers hatched. Last summer I was too busy preventing his dog from squashing a PiPl chick to get his license plate number, but not this time. The man and his dog left the parking lot.

Moving to the marsh

Shortly after the dog encounter, both Killdeer parents led the chicks into the marsh. To see the chicks navigate over the incline at the edge of the marsh was amazing; it must have seemed like fording a mountain to them. I’ve looked but have not seen the family since. I am hoping that they are thriving and growing in the marshland.

We don’t hear as much about Killdeer Plovers because they are not an endangered species. Killdeers are found in every state of the continental US, Alaska, Canada, Mexico, Central and South America. They are the least shorebird-like of shorebirds because they breed and dwell in many types of habitats including grasslands, fields, urban areas, gravel pits, airports, parking lots, athletic fields, and golf courses. Despite their super ability to adapt to human habitats, it is a species in decline.

Killdeers begin courting in our area in March. Although I imagine they have been nesting at Good Harbor Beach for a longer period of time, I only have a record of Killdeers nesting at GHB going back three years and it is yet another important reason as to why humans and pets should not be traipsing through the dunes.

It is difficult to tell the difference between a male and female Killdeer unless they are side-by-side, and even then, still challenging. The male is a bit larger.
