...VERY lucky today - just peeked in for a look at 12:50 Wpg time, one bird sitting on the nestbox, and immediately joined by a second bird - the first bird (turned out to be Trooper) then hopped into the nestbox, and was joined in there by Durand - I got a brief show of their bowing and squeaking to each other! Then Trooper took off, and Durand has been in and out of the box since.....way cool!
