Identifying the bird at Mount Faber

I have emailed Nature Society (Singapore) to help identify the bird which I spotted at Mount Faber. They have replied promptly, identifying it as the female Laced Woodpecker. The male bird will have a reddish crown.

Sighting of bird in Mount Faber

Last month, while walking up a flight of steps leading up to Mount Faber, I spotted this bird that was pecking fervently at a hole in a tree trunk. Is it a woodpecker?
