About the Peregrine photo. This species is variable both geographically and individually and the number of recognised subspecies varies a lot between different authors which have done independent studies. Ssp peregrinator is variable geographically and could be splitted to several subspecies, but there is also the extensive individual variation and where to draw the line? Also ernesti is variable and in some areas, for example in peninsular Malaysia, may show rufous on breast. This really may be because of peregrinator genes, but, for example, White et al (Peregrine Falcons of the World) discuss this and include all peninsular Malaysian birds in ernesti. According to them, ernesti meets peregrinator somewhere in the northern Peninsula and southern Myanmar. Wells (The Birds of the Thai-Malay Peninsula) also includes peninsular breeders in ernesti, although with some hesitation ('residents have not been identified formally but in the field appear close to subspecies ernesti').
So probably new names are not needed here.
