Oley Township, PA -  Darlene Moser has taken care of Mr. Grey since he was a baby parrot.

She's had him for about 20 years. He's named after the type of bird he is, an African Grey.

Mr. Grey was one of the more than 150 animals at Oley Turnpike Dairy, which features a petting zoo and is owned by Moser.

He knows how to say the words "hello," "goodbye," "shut up" and says the word "grape" when he sees the fruit, according to Moser.

When he sees a raisin, Mr. Grey calls it a grape and Moser has never been able to correct him.

But now she's worried that she may never see him again.

Mr. Grey, along with three other parrots - Sunny, a yellow sun conure and two Amazon parrots - were stolen from the petting zoo between Sunday night and Monday morning, Moser said.

"They were my babies," she said.

The Amazon parrots have green bodies with yellow heads and are a breeding pair, Moser added.

The thief or thieves were able to pry open the lock at the gate of the petting zoo in Oley Township and cut a hole in the wire of the animal house and crawled in, Moser said.

It appears the birds put up a fight because Moser said that there was blood spatter found at the scene and Rosie, a scarlet parrot, looked like she had been in a struggle, but apparently was able to fend off her would-be captor.

"It just seems a shame that somebody has to go and rob animals," Moser said.

It's not the first time that animals have been stolen from the Oley Turnpike Dairy.

In October 2015, two 5-month-old pygmy goats were taken from the fenced area outside the gated petting zoo. They were never recovered.

The dairy opened the free petting zoo more than 15 years ago to prevent curious visitors from sneaking down to the barns for a peek at the cows.

It started with one cow and added other animals over years, including monkeys, lemurs and wallabies.

The dairy posted its latest plight on its Facebook page Monday afternoon, asking for the public's help in bringing the parrots home.

As of 8 p.m., the post has been shared more than 7,000 times and had more than 100 comments from people offering suggestions or expressing support.

Collectively, the four parrots are valued at about $3,500, said Cpl. John Verno, a detective with the Oley Township Police Department.

An investigation continues. Anyone with information is asked to call police at 610-987-6656.

"We just hope they come back," Moser said.
