The following comparison shews clearly the principal

British and Irish Coal-Titmice :—•

The Plate (PI. X.), which has been drawn by Mr. F. W. 
Frohawk, shews the differences between freshly killed 
examples of the British and Irish Coal-Titmice very clearly, 
but it should be noted that in the most typical Irish birds 
the flanks are often of a brighter cinnamon in freshly killed 
examples.
