According to the official BBC TV Programme Information Birdsong will not air as late as April but in the week of January 21 to January 27!
You can find the information here. Exact date and time have not been confirmed yet but hopefully we will get more information soon.
Thanks to Mandy for the heads up!
I think the April air date is for the US. We always have to wait months/years to get UK shows.
Thank you, Summer. That seems plausible!
The air date was given last night and is in fact 22 January, so we are getting it way ahead of the States.
It was in fact intended to be a cinema release first, the trailer does look superb. Two episodes.
@ John: If you look at the main page you’ll see that I posted the confirmed air date yesterday. :)
