In November 2018 there was an unusually large number of Rose-ringed Parakeets (Psittacula krameri) around the vicinity of Sian Tuan Avenue. Some were feeding on the seeds of the Golden Penda (Xanthostemon chrysanthus) fruits grown along both sides of the road here. Others were on the roof of houses here. Closer observations revealed that they had pecked holes through the softboards to get access into the spaces under the roof. The parakeets had found safe nesting areas in the attic of houses here. These houses are mostly two storied.
Some months later the parakeets disappeared from the area. They probably found a better nesting area.

Around July 2021 when I was weeding in my garden, I heard pecking noises above. Looking up, I saw a parakeet pecking at the soft board under the roof edge. I paid no further attention to it until sometime later I noticed the softboard had totally separated from its wooden attachment and a pair of parakeets was inspecting the space inside through a large hole. Apparently once the parakeets got a grip on the edge of the softboard, they easily tore off pieces. The pair of parakeets continued pecking on the gaping softboard until one or more holes appeared on the detached softboard.

These holes became the entrances to the attic space inside the three-storied building. The parakeets then began bringing in dried plant materials to construct their nest inside the attic. Every mornings and evenings they were seen around the large entrance.

Subsequently the damage was repaired when the three-storied building was given a whitewash. In time I am sure the parakeets may return.

Over in South London and Kent, Ring-necked Parakeets have been known to be pests of buildings HERE. They nest in buildings as long as there are access holes. If the holes are small, they enlarge them with their powerful beaks. Once inside the roof space these parakeets can damage electrical wiring that can become fire risks, especially if there are dried nesting materials nearby. The parakeets can also damage the wooden structures inside HERE. The acid in the accumulated bird droppings can eventually degrade tar-based roofing materials, causing leaks in asphalt roofs. The droppings can also spread various diseases HERE.
