Late nesting?

[paul b]

Curious behaviour observed: a blue tit or tits flying repeatedly to a nest box sited on the house -caught on trail camera as well as seen by me; unlikely to be roosting because this is not just in the evening but throughout the day and the birds are in and out quite quickly.
Question is -could blue tits really be nesting in October/November? are there any records?

BTW-I am reluctant at present to disturb the box by inspecting inside. I will need to wait to see if behaviour continues and if chicks are heard in a few days.
