Nature Fact

During a recent study of an overnight roosting Blue Tit in a nesting box along the Hazel Drive fringe, it was recorded that in November, December and into January roosting commenced on the dot of twenty past four each afternoon. The bird vacated the box each morning between 7.20 and 7.40. It was established that weather conditions did not change the times but it was noted morning departure was connected to light levels as on darker days departure was delayed. An overall time of fifteen hours roosting was the norm. The photograph of the Blue Tit, as above, shows that a bird really does tuck the head under its wing when asleep.
