Great little birds & brilliant picture once again Gary. We do rear loads of blue tits & great tits & we have a camera in a nest box on the front of the hospital. A female great tit has laid, hatched & reared 7 babies each year for the past 3 years. Its great to watch how quickly they develop. On several occassions we have put babies in nest boxes with surrogate mums & they've reared them with their own.
