Swallows in late January 2014

A pair of Pacific Swallows roosting just outside my parent's house in Segamat, Johor. They will perch there from evening onwards. They disappear by early morning. Came home during the Chinese New Year week end of January 2014 and spotted this pair. They remained very still and unperturbed even amidst the noisy firecrackers and fireworks on the eve of Chinese New Year. There's a beautiful painting of a pair of swallows in website at  NZ Birds 

Swallows herald the coming of Spring so it was really a joy to see them that night when I was home in Johor to celebrate CNY with my family. According to Wikipedia, they are under the Passerines family species and their nests are usually made from mud. Didn't spot any mud nests within the compound so I gather these swallows are a migratory pair seeking temporary refuge in my parent's house.
