The Grooters are the result of two distinct lines, namely, the “Vossen†of “De Roden†and “De Witkelen.†“ De Witkelen†or “White Throats†are so called because their ancestors showed this characteristic in their plumage; these are, in all respect, beautiful birds. In this line, the pupil is very clear and rather large. The mutual basic circle is generally easy to detect, and it surrounds the pupil perfectly; it is not very large, but is extremely neat and clear. The first circle of the iris shows itself in the form of a small net, while the second, which is rather large as compared to the first circle, is of a vivid red color. The beak is somewhat larger than average, but devoid of extensive wattles. The ceres are very slightly developed. The plumage is very rich, and super-abundant. The wing feathers are very wide. The dominant colors are satin-black, light and dark, and pieds.
