Additional information
The holotype, RMNH 87007, is an adult female from 'Argentina' which died in the Amsterdam Zoo on 2 Apr 1896, donated to the RMNH by Kerbert, the director of the Zoo; tail 25, culmen 22, tarsus 30 (Büttikofer 1896, Van den Hoek Ostende et al. 1997). From Büttikofer (1896), it is perfectly clear that only this sole Leiden specimen served as a base for the description of the new taxon, even though it was in imperfect state due to its stay in captivity, e.g., showing incomplete wings. Therefore, it is important to note that other birds survived from the same live batch received from 'Argentina', in this case the specimen in the ZMA referred to above, and RMNH cat. nr. 2, female, died 21 Oct 1896, both in perfect condition and therefore far more suitable to settle the status of this taxon. When compared with a few birds of C. tataupa in the ZMA, the dark and extensive slate-grey head, hindneck, and underparts of these specimens of C. kerberti is striking, but larger series of C. t. tataupa in the RMNH show quite some variation in this respect. Also, the ZMA bird seems rather large when compared with the data of C. t. tataupa published in Blake (1977), though still within the range of measurements. As the localities from the tataupa series examined are poorly detailed, it seems possible that the dark birds among them form a separable geographical race to be named kerberti, but without a larger series with more exact locality details available Roselaar & Prins (2000) agreed with Hellmayr & Conover (1942, p. 79) in provisionally relegating kerberti to the synonymy of nominate tataupa.

Measurements
As far as types in the ZMA are concerned, all measurements were taken by C.S. Roselaar, unless otherwise noted, using the methods as described in Svensson (1992) and comparable with the data published in the Handbook of Western Palearctic Birds. All are in mm, and are given to the nearest mm when taken with a ruler and to one-tenth of a mm when measured with calipers.
