A newborn baby girl was found abandoned on a beach in Hawaii, according to reports.

The 8-pound child was “abandoned immediately after birth,” state Department of Human Services Director Patricia McManaman said, according to the Star Advertiser newspaper. She was found just before midnight on Sunday.

McManaman said the girl was “doing quite well” and drinking formula, HawaiiNewsNow.com reported.

Both reports said the child was found on Sandy Beach by a 21-year-old woman, who took her to a local medical center. The woman is not a suspect, according to police.

The mother has not been identified, HawaiiNewsNow.com said.

Jonathan Kamai, a Sandy Beach regular, told the website that he was glad “the child had an angel that came and helped her out.”

“It would have to be something tragic for someone to just leave their newborn here," he added. “Just as a father, how somebody could actually just do that kind of stuff – it's just crazy.”

Authorities are looking for clues in the death of a newborn girl who was found Sunday floating in a pond in a suburban Virginia town about 30 miles west of Washington, D.C.

The Loudoun County Sheriff's office said a resident of Sterling, Va., reported seeing a deceased baby in a pond behind a cul-de-sac shortly before noon Sunday. 

Authorities responded to the scene and declared the infant dead. They said the birth did not appear to have occurred in a hospital and that the mother may need medical attention.

Authorities spent hours Sunday knocking on doors in the neighborhood adjacent to the pond, near Awsley Court and Steed Place in Sterling, hoping to find the mother, NBCWashington.com reported.

Neighbors told NBC some local residents fish in the pond, and it is also a popular hangout for teenagers.

A baby girl was found at the rear of a housing complex in Queens late Sunday night.

Police are searching for the parents of a newborn baby girl found behind a building project in New York City.

According to The Associated Press, a passerby heard a baby crying at about 11:40 p.m. Sunday near the Woodside Houses, a city housing complex in Queens, and called police.

According to the New York Post, the infant was only one or two days old.

"I heard a baby crying and somebody yelling 'there’s a baby behind the building,'" Essence Shepherd told the Post.

Discovered in a grassy area, the baby was wrapped in bath towels and sheets. She appeared to be in good health, the AP reported. Authorities took her to Elmhurst Hospital.

A hospital spokesperson told NBC News the baby weighs about 6 pounds and is healthy. The hospital will hold her for about 72 hours, and then release her in the care of the city's Administration for Children's Services.

Residents were shocked at the news.

"That is very cruel," Audra Adams, a resident at the building project for the last 40 years, told the AP. "You couldn't knock on somebody's door or take the baby to a hospital or something? This was your only recourse? I hope they find her."
