The quickest way to tell them apart
Wait for the bird to call. Both species call often as they move through the trees, and the two main calls sound nothing alike. "Pitchoo" is short, bright and sneezed out. "Chay-chay-chay" is slow, low and nasal, like a tiny angry buzzer.
In the field, a call plus one or two supporting marks is the standard to aim for.
By sight
Treat every visual mark as support, not proof.
- Bill spot. Marsh Tits have a small pale mark on the upper bill, just below the nostril. Willow Tits have an all dark bill. On a good photo this is the most reliable feature.
- Wing panel. Pale edges to the inner wing feathers give most Willow Tits a light panel on the closed wing. Marsh Tits look plain winged. Worn summer birds can lose it.
- Cheek. A two-tone cheek (white, then brownish) points to Marsh Tit. An all white cheek points to Willow Tit.
- Shape. The Willow Tit looks bull necked. The Marsh Tit looks slimmer.
Bib size is often quoted but varies too much to trust.
By sound
Learn the two calls before you go. The Marsh Tit's "pitchoo" is loud and sudden, and is often followed by a quick, scolding "chicka-dee-dee-dee". The Willow Tit's call is a string of harsh, nasal notes, each one long and buzzing: "zi-zi, chay, chay, chay".
Songs help less. Marsh Tits sing a simple rattle on one note from late winter. Willow Tits sing rarely: a short series of clear, sad whistles that fall in pitch. Record what you hear and check it in Sound ID.
By season and habitat
Both are resident and stay on or near their territories all year, so season will not help. Range and habitat will.
Marsh Tits live mainly in England and Wales, in large, mature broadleaved woods. The name misleads: they are not birds of marshes. Willow Tits prefer damp, scrubby, younger growth, including overgrown former industrial land, because they need soft rotten stumps to dig a nest hole in.
The Willow Tit has gone from most of south-east England and is now found mostly in parts of northern England, the Midlands, Wales and south-west Scotland. In much of the south, a bird of this pair is a Marsh Tit almost by default. Neither occurs in Ireland.
Common mistakes
- Naming one from a brief view at a feeder. Without a call or a clear photo of the bill, log it as "Marsh or Willow Tit".
- Overlooking the Coal Tit, which also has a black cap and bib. It has a white stripe down the back of the head and two white wing bars.
Where to see both
Few sites now hold both, and none of our hotspots is reliable for the pair. For Marsh Tit, RSPB Leighton Moss is a well-known site: watch the feeders and the woodland paths. For Willow Tit, look for damp scrub and wet woodland reserves in northern England and the Midlands, and ask the local bird club where the species still hangs on.
FAQ
Can you tell a Marsh Tit from a Willow Tit by sight?
Sometimes, with a close view. The pale spot at the base of the Marsh Tit's bill and the pale wing panel on the Willow Tit are the best marks. Neither is easy to see in the field, so most birders rely on the call to confirm.
How rare is the Willow Tit in the UK?
It is in serious trouble. The BTO estimates about 2,750 pairs (2016) and a 97% fall between 1967 and 2024. It is Red listed and has disappeared from most of south-east England.
Do Marsh Tits live in marshes?
No. Marsh Tits live in mature broadleaved woodland, mostly oak and beech with plenty of undergrowth. The Willow Tit is the one more likely to be found in damp, scrubby ground.
Log both tits
Marsh Tit and Willow Tit are both in the Birdedex. The Willow Tit is one of the hardest resident birds to add, so log it the day you hear that call.
