I can report that the Long-tailed Tit pair building their nest (see 2nd March blog post) appear to have completed the task. It took approximately three weeks to build.
Although I am not able to observe, I assume now that the female will begin to lay her eggs. Apart from shift changes, there will be very little action from now on until feeding starts and then fledglings emerge.
As you can see below, this Homemaking lark is rather tiring.
One of the pair was caught having a brief sleep during the period I was there.
