Description:
Coal Tits are
slightly smaller than the Blue Tit, with olive-grey upperparts
and white-buff underparts. Although in general appearance
they are reminiscent of both Willow and Marsh Tit, they have
a characteristic head pattern, with a black bib, white cheeks
and a black cap that extends down to the base of the neck
at the sides. In the middle of this black cap, running from
just below the top of the head back down to the neck is a
rectangular white patch, so this is one species where a back
view can help identification.
The calls of
the Coal Tit are a bit like a weedy, higher-pitched version
of the Great Tit, with a thin-sounding ‘tsee-tsee-tsee’
call and a basic song of ‘teachoo-teachoo-teachoo’
repeated several times.
Ecology & Behaviour:
Coal Tits are
often regarded as being a species of coniferous woodland,
and while they do nest at higher densities in coniferous woodland
than deciduous woodland, Coal Tits do occur in many other
habitats, including gardens. The narrower, more slender bill
is an adaptation to feeding in conifers.
Coal Tits begin
nesting slightly earlier than Blue Tits and some time before
Great Tits. They will use boxes with small entrance holes
and there is some evidence to suggest they might prefer nest
boxes with a narrow vertical slit to those with a round hole.
Their smaller size means that they are often out-competed
by the larger relatives when it comes to finding and defending
nestboxes. Coal Tits prefer nestboxes mounted on conifers
to those mounted on deciduous trees. Interestingly, Coal Tits
often carry food away from a feeding station to store elsewhere,
a behaviour that is also seen in other tits (especially Marsh
Tit) but to a lesser degree.
