Even more on Tawnys...

I've covered about 40% of my boxes so far and have a occupancy rate of about 50%. However, having checked the 'best' boxes first, I am expecting that to fall. Half the birds are still on eggs and only one brood big enough to ring. I also retrapped a female ringed in same wood as an adult 7 years ago.
