The tail of one randomly selected male within each group was cut to about 14 centimeters (5 inches) in length. Each removed feather was then glued to the corresponding feather of another male, elongating his tail by 20 to 30 centimeters (8 to 12 inches). The two other males in the group served as controls. One had his tail cut and repaired ...
The tail is bicolored and extends greater than one-third the animal's total length. [3] The type specimen measured 185 mm (7.3 in), with a 65 millimetres (2.6 in) tail and a 21 millimetres (0.83 in) hind foot. [5] The ear measured 14 millimetres (0.55 in) x 8 millimetres (0.31 in) x 13 millimetres (0.51 in). [5]
The wings and feathers may often be flattened to maximize the measure. Still, in many cases, the chord length with natural curvature is preferred. [4] [5] In some cases the relative lengths of the longest primaries and the pattern of size variation among them can be important to measure. The wing width can also be measured from the carpal joint ...
The coracoid is robust and broad, measuring 16.7 cm (167 mm) long and 14.8 cm (148 mm) in height. The anterior edge had a coarse texture, likely for the articulation with cartilaginous tissue. A large foramen was located from the front to the back, probably acting as a channel for blood vessels and nerves. The radius measured 26 cm (260 mm) long.
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate. [5]
The tail has only sparse hair for most of its length, but with a distinct brush-like tuft of hair at the tip (although the common name is, perhaps, more likely to come from brushy environment in which it lives). It has a head-body length of 86 to 105 mm (3.4 to 4.1 in) with a tail 88 to 115 mm (3.5 to 4.5 in) long.
The spotted dove was formally described in 1786 by the Austrian naturalist Giovanni Antonio Scopoli and given the binomial name Columba chinensis. [2] Scopoli based his account on "La tourterelle gris de la Chine" that had been described and illustrated in 1782 by the French naturalist Pierre Sonnerat in the second volume of his book Voyage aux Indes orientales et à la Chine.

This species has been described as a tiny (at only 13–15 cm (5–6 in) in length, including its 7–9 cm (3– 3 + 1 ⁄ 2 in) tail), round-bodied tit with a short, stubby bill and a very long, narrow tail. [11] The sexes look the same and young birds undergo a complete moult to adult plumage before the first winter. The plumage is mainly ...
