The marsh tit (Poecile palustris) is a Eurasian passerine bird in the tit family Paridae and genus Poecile, closely related to the willow tit, Père David's and Songar tits. It is a small bird, around 12 cm (4.7 in) long and weighing 12 g (0.42 oz), with a black crown and nape, pale cheeks, brown back and greyish-brown wings and tail. Between 8 and 11 subspecies are recognised. Its close resemblance to the willow tit can cause identification problems, especially in the United Kingdom where the local subspecies of the two are very similar; they were not recognised as separate species until 1897.
Globally, the marsh tit is classified as Least Concern, although there is evidence of a decline in numbers (in the UK, numbers have dropped by more than 50% since the 1970s, for example). It can be found throughout temperate Europe and northern Asia and, despite its name, it occurs in a range of habitats including dry woodland. The marsh tit is omnivorous; its food includes caterpillars, spiders and seeds. It nests in tree holes, choosing existing hollows to enlarge, rather than excavating its own. A clutch of 5–9 eggs is laid.

With luck
About 10% of wildlife watchers report a Marsh Tit sighting in Aigüestortes National Park on a given day, based on 52 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th most-seen of the 114 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August and October–April
In those months about 10% of wildlife watchers report a Marsh Tit in Aigüestortes National Park on a given day, against under 5% in May–July and September, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Marsh Tit sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Marsh Tit is recorded against all the birds logged in Aigüestortes National Park (52 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
