COLYMBUS. 97 
confirmed in the opinion from an error in Sepp, who has given a figure 
of each as male and female. 
We can, however, with certainty refute this opinion, from various 
opportunities of attending to the nests of both species. 
The nest of this bird is placed in some hole, either in a wall or a 
tree ; it is composed of moss and wool, lined with hair ; the eggs are 
six or seven in number, less than those of the marsh tit, of the same 
colour, white, spotted with rusty red ; but the spots are smaller and 
more numerous ; their weight is fourteen or fifteen grains. 
The Cole Tit is not so plentiful a species as the marsh tit, keeps 
more in the woods, and seems to live entirely on insects, as we have 
never been able to discover it partaking of flesh or grain with the 
other species ; its note is also different. 
*“In Scotland,” says Selby, “1 have found it abundantly in all the 
pine forests, which seem to be its appropriate and favourite habitat, to 
the comparative exclusion of the other species. In these extensive 
tracts, covered by the natural growth of the country, or planted by 
the great landed proprietors, it has both a secure retreat and a constant 
supply of food, consisting of the aphides, larvae, and others of the 
insect tribe that are peculiar to the different species of fir, together 
with the seeds and berries of various evergreens. It is very lively in 
all its motions, and rivals the blue tit in the attitudes it assumes in 
quest of its prey, amid the higher branches of the pines. Its note 
is shriller and more pleasing than in the other species, and tends much 
to break the gloomy solitude of the tracts it frequents.”*
