This species is so nearly allied to Falco Msalon, that it is extremely 
difficult to distinguish many individuals. The number and form of 
the scutella differ ; but the most certain distinctive character is found 
in the light-coloured bands of the tail, which are more numerous in 
the Merlin, there being seven on its middle, and nine on its lateral 
tail-feathers.
