Help identifying small bird with clicking song - audio

I heard this bird this evening around 20:30 and believe there was actually two of them.

Here is the link :) makes an appearance at the start and at around 40seconds in

It was very loud and moving around the trees a little. As you may be able to see it seems to be a light brown/ reddish colour. 

Had a little look online but can't seem to find anything!

Any suggestions would be great :)

Thanks!
