Frankie the Flying Fox winged it to the preschool on Friday to help Tamworth Regional Council show how "absolutely crucial for the environment" the mammals are.

Trainee environmental health officer Alex Habilay told the littlies about flying foxes' activity patterns, food sources, survival strategies and even toileting habits.

The council will follow up with Bat Night in Bicentennial Park next Friday from 5pm, intended to be a fun and educational evening featuring information stalls, games and crafts.

"Certainly not everyone likes flying foxes, but they are very important for our environment," council compliance manager Ross Briggs said.

"Without them, the eucalypt woodlands and the native forest that we have today would not regenerate to the degree that they do."

Mr Briggs said there were now fewer than 1000 flying foxes still roosting near the Bicentennial Park footbridge, a "resident colony" that would probably stay for the rest of the year.

"We had 90,000 of them here in Bicentennial Park this year, and we didn't get any complaints to council," he said.

"They make a bit of noise, they smell, but I think if they're left alone during the day, they quieten down and they don't have that activity where they're moving around all the time."

Bat Night will include watching the flying foxes start their nightly decampment to seek out their dinner of pollen, nectar and fruit.

"We were hoping to have the bigger numbers there, so that we could watch a fly-out on the night, so we'll see how that goes," Mr Briggs said.

He said the park was a roosting spot greatly preferable to residential areas - such as the King George V Avenue area, which was home to more than 100,000 of the mammals in 2017.

However, Mr Briggs said, the council was doing some habitat restoration work where Goonoo Goonoo Creek and the Peel River meet, to encourage the animals away from the park.
