Watching and waiting

The female sitting on the tower today.

No sign of a male....

Some activity

The female (Bella?) was on the tower today...

 ...making lots of noise and occasionally flying off to return a few seconds later.

I did briefly see the male (CR?) fly past, which made her squawk even louder. 

A waiting game...

Nothing happening yet, although one bird was roosting on the tower tonight.

Can't be long now....?
