Common mynahs are tame, bold, and noisy birds; usually seen in pairs or small flocks. They build bulky nests in tree cavities, pockets in buildings, in heavy vegetation and in thatch roofing! A pair moved into my garden a couple of years ago and took to nesting in the little thatch roof over my front entrance gate. Despite numerous attempts at evicting them and repairing the roof, they have been very persistent and this is the current state of my little thatch entrance!
Females lay four to five glossy, pale blue eggs. The incubation period is thirteen to eighteen days. Both parents incubate the eggs. The nestlings may leave the nest at around twenty-two days or longer, but may still not be able to fly for another seven days or so. And this happens several times a year! Mynahs are very territorial and every time nestlings have fledged, I've watched the parents lead them away from our property as soon as they could fly, returning empty-handed and the cycle starts all over again.
The Myna has been introduced in many other parts of the world and its distribution range is on the increase to an extent that, in 2000, the IUCN Species Survival Commission (IUCN) declared it among the World's 100 worst invasive species. The Myna is one of only three birds in this list of invasive species. It is a serious threat to the ecosystems of Australia and South Africa.
However, the intelligence and loving spirit of these amazing birds is beyond description. When I rescued a fledgling a couple of years ago, I called her Mai and she grew up in my studio and had free range of the house and garden, and one of her favourite past-times was her early-morning bath in the bird bath in the garden, after which she would fly into my studio, roosting on top of the computer screen, preening herself until she was all sparkling and shiny.
They are also extremely playful and inquisitive. She would investigate every item in my studio, picking up the gemclip holder, fishing out a few and then hiding them in all sorts of nooks and crannies, often returning to find and play with her treasures.
She was extremely fond of people and one day, after approaching somebody in our driveway, she disappeared mysteriously and I'm convinced that she landed on their shoulder and that the person climbed into their car and drove off with her. I was totally devastated, and I just prayed that they did not cage her, as she was a wonderful free spirit.
