A picture will be very useful, as this doesn't sound gravid.
There is a chance there is an alternative explanation, but tit is not too late in the year for her to be gravid, just because corns generally breed around spring time, does not mean a pair that co-habit all year round won't breed at any opportunity, this female being gravid is a completely valid possible explanation.
