2. Parus [c.] cristatus

The distribution was presented by Engel (1952), Mauersberger and Stephan (1967), see also Löhrl (1982). The geographical variation of the Crested Tit proves to be predominantly subtle and clinal; see Vaurie (1957: 16–17), Stugren and Kohl (1964), Kohl (1967), Roselaar (1995).

P. cristatus scoticus (PRAZÁK, 1897) [loc. typ. restr. Strathspey, Scotland]; P. cristatus cristatus L., 1759 [ Sweden]; P. cristatus baschkirikus (SNIGIREWSKI, 1931) [Miass, S Urals]; P. cristatus weigoldi TRATZ, 1914 [Favaios and Alijo, N Portugal]; P. cristatus abadiei JOUARD, 1929 [Lambézellec, Finistère, Brittany]; P. cristatus mitratus C.L. BREHM, 1831 [conifer forests of Germany]; P. cristatus bureschi V.JORDANS, 1940 [above Bansko, Pirin Mts., Bulgaria].

The population group: P 44 scoticus, abadiei, weigoldi, cristatus , baschkiricus, mitratus, bureschi; Europe. — Fig. Quinn: Plate 20: 68, in part.

* Roselaar (1993 in Cramp & Perrins, 7: 206) described the geographical variation in great detail; it consists substantially of clinal coloration shifts from reddish brown to grey. The isolated Scottish population is smaller, and the Crested Tits in SW Europe are probably also. — Wing length from Saxony and Lusatia: 22 ♂♂ 64–68 mm, x = 65.8 mm ± 1.28; 16 ΨΨ 62–65 mm, x = 63.3 mm ± 1.17. Tail length: 22 ♂♂ 50–54 mm, x = 52.0 mm ± 1.12; 16 ΨΨ 49.5–51.5 mm, x = 50.5 mm ± 0.72. — TWI of 22 ♂♂ 75.4–81.5%, x = 79.1% ± 1.89, of 16 ΨΨ 76.9–82.4%, x = 79.9% ± 1.50.
