Both are becoming increasingly rare in the UK - for this reason alone it is not very usual for them to be in the same area. However, where both still occur, they can attend the same feeders.
I live outside the UK and in an area where both are common - I have two feeding stations. At the first (basically gardens) I only get Marsh Tits regularly, with Willow Tit just very occasionally in winter. At the second though (flood forest), Marsh Tit is still the more common, but Willow Tit relatively common, more so in some years. Last winter, there were 27 Marsh Tits and eight Willow Tits at my feeders in total, both often present at the same time. Currently, in this very early winter period, I have six Marsh Tits at my feeders and five Willow Tits.
We have one Willow Tit attending at the moment which is unusual. We often have them in the surrounding Birch but they rarely if ever, use our balcony feeder.
We have a Jay at the moment as well, they don't usually come to our feeder, possibly due to the style of the feeder more than anything else but it made me wonder if it's been a bad year for Acorns?
