WHERE DO PIPING PLOVERS GO IN BAD WEATHER?

A question often asked is “where do the birds go when the weather is inclement?”

The answer depends on what type of bird. Some birds, like perching birds, have it a bit easier than seabirds and shorebirds because their little toes reflexively cling tightly to a branch or limb. But many, many birds lose their lives in hurricanes and super storms.

Extreme weather events are especially harmful to threatened and endangered shorebirds. Wave action, high winds, and storm surges destroys coastal habitats and flooding decreases water salinity. Birds, especially young birds, are blown far off course away from their home habitats. A great deal of energy is expended battling the winds and trying to return home.

In the case of Piping Plovers, for the most part, business continues as usual during average inclement weather. You won’t see them sit in a tree or dune shrub because they will lose their primary advantage against predators, that of the safety afforded them by the camouflage of their sandy beach coloring.

Perhaps they’ll find a rock on the beach, or ridge in the sand, to crouch behind and out of the path of the wind. Piping Plovers are much harder to find in inclement weather because their feathers mirror shades of rain and snow and fog. Drenching rain, spring snow squalls, and biting summer sand storms won’t stop these indefatigable creatures, we see them foraging during every kind of weather event.

Even Piping Plover chicks, weighing not much more than nickel, have the ability to withstand harsh summer sandstorms.

HOW DO HURRICANES AFFECT MIGRATING SHOREBIRDS LIKE LITTLE CHICK

We can hope our Little Chick is taking his time migrating southward. Perhaps he has traveled only as far as Cape May, New Jersey, or maybe he has already migrated as far as Cape Lookout, North Carolina. Migrating shorebirds often travel shortly after a low pressure system and hurricanes are a part of the environment to which wildlife like Piping Plovers have adapted. However, no wildlife has in the recorded history of the world had to cope with a storm the magnitude of Hurricane Irma.

Extraordinary weather events can push endangered species over the brink. High winds, storm surges, and wave action destroys coastal habitats and flooding decreases water salinity. Songbirds and shorebirds are blown far off course away from their home habitats, especially young birds. A great deal of energy is expended battling the winds and trying to return to course. Songbirds have it a little easier because their toes will automatically tighten around a perch but seabirds and shorebirds are the most exposed.

Shorebirds like Piping Plovers feet have evolved to run over sand easily and do not grip well with their toes.

Numerous Piping Plovers winter over in the low-lying Joulter Cays, a group of sandy islands in the Bahamas, and one of the areas hardest hit by Hurricane Irma. Perhaps migrating PiPl sensed the pending hurricane and held off before crossing the Atlantic to reach the Bahamas and other Caribbean Islands. The flock of nine PiPl in the above photo were seen last year at the end of August in Gloucester (August 29, 2016.)

One famous shorebird, a Whimbrel named Machi, who was wearing a tracking device, became caught up in the eye of a powerful storm but made it through to the other side of the storm. Tragically, he was subsequently shot dead in Guadeloupe. Many migrating birds like Whimbrels know to avoid places like Guadeloupe where unbridled shorebird hunting is allowed, but Machi had no power over where he made landfall. Sea turtles too are severely affected by the loss of barrier beaches. Staggering loss of life has been recorded after recent powerful hurricanes–fish, dolphins, whales, manatees, baby crab and lobster estuaries, insects, small mammals, all manner of birds–the list is nearly as long as there are species, and nothing is spared.
