with hair or felt ; the usual complement of eggs is 

 four." 



I have never been in any of the Highland breeding- 

 localities of this bird at the nesting-season, but I may 

 here mention that a nest now in my possession, sent to 

 me from Scotland many years ago, tallies exactly with 

 Col. Irby's description, being decidedly scanty in 

 material as compared with nests of other species of the 

 family, composed of fine green moss and lined with 

 hairs of the Squirrel. I found this Titmouse in con- 

 siderable abundance during the winter months in the 

 fir-woods of the Canton de Vaud, near Lausanne ; it 

 certainly breeds there, but was comparatively scarce in 

 April and May, probably retiring as a rule to higher 

 ground for nesting purposes. I met with this species 

 on the Spanish side of the Pyrenees in Aragon and 

 Navarre, and Col. Irby informs me that it is common 

 in the cork- and pine-woods in the neighbourhood of 

 Gibraltar and Algeciras. 



The Crested Titmouse in habits resembles the other 

 members of the Tit family, being an active restless 

 bird, constantly on the move in search of food; the 

 ordinary call is a jarring monosyllable, followed by 

 three or four prolonged ringing notes. This bird, in 

 my experience, does not long support confinement in a 

 cage.
