BLACK-BELLIED PLOVERS AT GOOD HARBOR BEACH!

A trio of Black-bellied Plovers was foraging at Good Harbor Beach late Wednesday afternoon. They were only there very briefly; Black-bellied Plovers flush easily and the three skittishly flew off together when a happy group of noisy kids came along.

We will never see Black-bellied Plovers nesting. They are migrating north, to breed along the Arctic coast, from Baffin Island, Canada to western Alaska. Just like Piping Plovers, Black-bellied Plover males build nest scrapes and both male and female incubate the eggs.

The eggs look very similar to Killdeer eggs (Killdeers are also a species of plover), the eggs of both species are darker than Piping Plover eggs, and both are more heavily spotted at the large end.

So many species of shorebirds nest in the Arctic. We are so fortunate that Piping Plovers and Killdeers nest on our shores, providing a wonderful window into the life stories of these amazing and resilient creatures.

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.

WHAT ARE THOSE CRAZY BIRDS RUNNING AROUND GOOD HARBOR BEACH PARKING LOT?

Killdeer Chick

Lost of folks are asking, are the Piping Plovers nesting in the Good Harbor Beach parking lot? The answer is no, the Piping Plovers are nesting on the beach near boardwalk #3. The mama and papa, and now chicks, that are running all around the GHB parking lot are a shorebird named Killdeers. Comparatively quite a bit larger, and more commonly seen, Killdeers are related to Piping Plovers, but are a different species.

Killdeer Chicks and Parent, Good Harbor Beach 2016

That I am aware of, this is the second year in a row Killdeers have chosen to nest at the Good Harbor Beach parking lot. It is frightening to see the babies zoom in and out between the cars. The mom and dad give vocal cues to the chicks, but still they run willy nilly. Killdeers have a fondness for human modified habitats, such as the GHB parking lot, and a willingness to nest close to people.

Like Piping Plover chicks, Killdeer chicks are precocial. That is a word ornithologists use to describe a baby bird’s stage of development at birth. Precocial means that shortly after hatching, the bird is fully mobile. Plover chicks are not completely mature, they still need parents to help regulate their body temperature, but they have downy feathers and can run and feed themselves within moments after emerging. The opposite of precocial is altricial. Birds that hatch helpless, naked, usually blind, and are incapable of departing the nest are altricial. Robins and Cardinals are examples of altricial birds.

Adult Kildeer

If you encounter the Kildeer family and would like to take a photo, or simply observe these adorable babies on-the-go, my advice is to stand quietly and don’t chase after them. Running after the chicks will put the parents into panic mode and they may lose sight of the other siblings. As the chicks mature, they will spend less time in the parking lot, and more time in the marsh and at the tidal river edge. Kildeer adults, and even the chicks, are actually good swimmers. Last year the Kildeer family crossed the tidal river and spent the second half of the season on the opposite side of the marsh.

Compare the Killdeer chick above, to the Piping Plover chick below.

At Good Harbor Beach – Plovers Here There and Everywhere! – Tips on How to ID Piping Plovers, Killdeers, and Semipalmated Plovers

Female Piping Plover Good Harbor Beach Gloucester copyright Kim SmithFor the past ten weeks, each morning very early before work I have been filming the Good Harbor Beach shorebirds and their habitat, and when not too tired from work, would go back again at the end of the day. For the most part, it has been a tremendously educational and rewarding experience, and I love Good Harbor and its wild creatures even more than when I began the Piping Plover project. We are so fortunate to have this incredibly beautiful and beloved treasure of a beach in our midst, and so easily accessed. As much as I have enjoyed filming the wildlife, it has been equally as fun to observe the myriad wonderful ways in which people enjoy the beach recreationally and that too is part of the Good Harbor Beach Piping Plover story.

Good Harbor Beach is currently home to three different species of plovers. We all know about our beautiful Piping Plover family. The lone surviving chick and Dad were last seen heading deep, deep, deep into the salt marsh. Since that time, several new Piping Plovers have joined the scene, two females and a male. We can tell they are different from our original mated pair by their feather pattern and bill color.

It was pretty scary filming the Killdeer family because all six were running willy nilly every which way throughout the beach parking lot on a very busy weekend morning. In the next photo, taken several days ago, you can see that the family has grown rapidly.

Notice the two dark bands around the neck and chest of the Killdeer.

The third species of plovers at GHB is the Semipalmated Plover. Although only slightly larger than the Piping Plover, the difference is easy to spot by the darker brown wings. Compare the single neck ring of the Semipalmated Plover to that of the Killdeer’s double set of bands. Unlike Piping Plovers and Killdeers, Semipalmated Plovers do not breed in Massachusetts but in northern Canada and Alaska. At this time of year we are observing their southward migration to the southern United States, Caribbean, and South America.

Semipalmated Plovers are often seen in mixed flocks with Semipalmated Sandpipers and Least Sandpipers. Semipalmated Sandpipers have black legs. Least Sandpipers have distinctly colored yellowish legs.
