CHARACTERS AND ALLIED FORMS. For allied forms see p. 247. The 

 long graduated tail, white centre of crown, and pink colouring of 

 scapulars, back and flanks distinguish it from all other British 

 species. 



FIELD-CHARACTERS. Delicate pink and grey tints and inordinately 

 long tail render this tiny bird unmistakable. Associates much 

 Avith other Tits, but is often seen in exclusive bands. White lateral 

 feathers in black tail are conspicuous as the birds pass with weak 

 flight from one tree to another. Call-note, a feeble " tsee, tsee " 

 which resembles that of other Tits, is often punctuated by a low 

 " tchup," which is very distinctive. 



BREEDING-HABITS. Builds a large upright ovoid-shaped nest, with 

 entrance hole near top, usually in thorn bushes, furze or brambles, 

 but sometimes also in orchard trees, conifers, oaks, birches, sometimes 

 at considerable heights. Materials used are chiefly moss (hypnum)
