Piebald is a 16th-century word that refers to the black and white plumage of the magpie bird; “pie” refers to the bird and “bald” means “white” or “spotted.”
The blotchy deer, which in some cases appear almost pure white, are the result of a recessive gene, said Aphrodite Montalvo, citizen participation specialist with the New York State Department of Conservation.
“A piebald deer is a partial albino, or is only partially missing pigmentation,” she said. “A true albino will have no pigmentation, so it will have pink eyes and nose and be fully white.”
Ms. Montalvo said the animals are rare; though the DEC has not conducted studies on the number of piebald deer, data from other states suggest they constitute less than 1 percent of the population.
That number can be slightly higher in protected areas or areas where natural predators such as the coyote or bobcat have been removed from the landscape, Ms. Montalvo added. They may occur more frequently here than in upstate areas, where predators can pick off the snowy fawns, whose natural response is to lie down and hide in dense cover.
“As you can imagine, it makes it difficult to hide when the animal is stark white,” she said.
“That’s the neatest part about these deer,” said Mr. Standish. “They don’t know they’re white, but they still have that instinct to hide. So you’ll see a buck lying down in a pile of briars, but he’s standing out clear as day.”
Cutchogue hunter Lisa Dabrowski said that although she hasn’t hunted in many years, when she did she let piebald deer be and believes other hunters do the same, even though they are easier targets than most.
In fact, she said she considers the animals good luck and recently fi lmed one she’s seen in the Fort Corchaug area.
“Most hunters have a great respect for nature,” Ms. Dabrowski said. “Just because it’s a white deer doesn’t mean it’s something someone will go make a trophy out of. It’s something we appreciate and protect. Most hunters will look at it from afar and only want to photograph it because it’s special.”
In addition to their unusual color, the bodies of piebald deer are somewhat different, said Ms. Dabrowski.
“They have narrower heads and short legs but are the same length,” she said.
Despite piebalds’ unique look, Ms. Dabrowski and Mr. Standish said, the unusual deer behave like all other white-tailed deer and are not shunned for their appearance.
“Let’s say a doe had two fawns and one was piebald, I never saw the doe not be with that fawn,” Mr. Standish said. “I was watching a piebald buck rut one time and he rutted like any other buck would. He just had longer hair and looked short and stocky. If I hadn’t known better, I would have thought he was a goat,”
Riverhead hunters are also familiar with the ghostly deer in local forests.
Tom Gabrielsen, brother of Riverhead Town Councilman George Gabrielsen, said he’s seen one while hunting on the former Grumman property in Calverton.
He watched another piebald grow from a fawn to a huge buck in Sears Bellows County Park in Hampton Bays. Though he was a 12-pointer (more points mean a larger rack of antlers), Mr. Gabrielsen said hunters let him be, especially at a park ranger’s request.
Hunters aren’t the only people who enjoy the piebald deer.
One animal in Wading River earned the affectionate handle “Sweetie Pie” from resident Christine Sackett.
Ms. Sackett, who has lived in the hamlet for just over a year, said she sees “Sweetie Pie” and her three fawns just about every dawn and dusk.
Animals that are most active in the morning and at twilight are called crepuscular, as opposed to nocturnal or diurnal. The reason deer are such a hazard to drivers is they’re most active during commuting hours. Ms. Sackett normally sees Sweetie Pie and family at around 6 a.m. and 6 p.m.
She and her husband can now come within two feet of the deer without disturbing them, she said, as they have come to know their friendly human neighbors.
“She has one fawn from last year who stays with her and she had twins this past year,” she said. None of the offspring is piebald. “I just started calling her Sweetie Pie because I was thinking she’s very gentle and she’s a piebald, so, Sweetie Pie.”
