The only one to fledge today I think, I seen another poking it's head out of the nest box but didn't pursue the mother trying to encourage it out with food. Both nest boxes have been up over 20 years, only one ever gets occupied but the smaller one only seems to get used now.
The numbers of chicks have been smaller in the last few years, I never seen a single caterpillar get brought in the last number of weeks. My theory is the LED street lighting is mucking up the moths life cycle.
