The Marsh Tit will use a nest box, but thrives best if it can excavate part of the nesting material itself — a trait it shares with its close relative the Crested Tit.
| Measurement | Value | |---|---| | Entrance hole | approx. 27–30 mm | | Mounting height | 1–3 m | | Location | damp deciduous swamp forest or mixed woodland near water |
Nesting material: fill the box with wood shavings — the Marsh Tit, like the Crested Tit, prefers to excavate a box filled with soft material rather than an entirely empty box.
Placement: put the box up in damp deciduous swamp forest or mixed woodland near water rather than in pure coniferous forest, where the Marsh Tit rarely breeds.
Put the box up during the winter half of the year, before the breeding season begins.
Clear out old nesting material in late autumn to reduce the risk of parasites.
