I noticed the male and female take turn in the nest, very good! ;)
There is always at least one parent guarding the nest, maybe they are afraid of raiding by nest parasites like Cuckoos.
The female was there roosting inside the nest when I check it just now at 10.00pm. According to Ali & Ripley, incubation period is about 14 days. When I found the nest of 4th February, I don't know how many days the bird already incubating. So I have to watch out for the hatchling /feeding activity soon.
