BirdBox2018: Blue Tits hatch in Great Tit nest

All 6 of the blue tit eggs hatched by the 15th May.

By my reckoning it was almost 5 weeks from the time the first egg was laid until the last had hatched.

After all, if bats could safely feed during the day, they wouldn't bother to stumble around in the dark of night. 

So its good to catch the occasional ultrasonic recording of bats catching their prey.
