386 INSESSORES. SITTA. Nuthatch- 



commonly making use of the deserted habitation of a Wood- 

 pecker ; and Montagu tells us, that its first step is that of 

 contracting the orifice by a plaster of clay, so as barely to ad- 

 Nest, &c. mit of a passage for itself. — The nest is composed of the dead 

 leaves of the oak and other trees, put together without much 

 regularity ; and it lays from five to seven eggs, of a greyish- 

 white, spotted with reddish-brown colour, and very similar to 

 those of the great Titmouse. During incubation, the female 

 sits very close, and it is almost impossible to drive her from 

 the nest ; she defends it to the last extremity, striking with 

 her bill and wings, and making at the same time a hissing 

 noise. In the spring, this bird produces a loud and shrill 

 whistle ; but the singular noise attributed to it by Dr Plott, 

 in his History of Oxfordshire, has been ascertained to pro- 

 ceed from the true Woodpeckers. It is found throughout 

 Europe, and is stationary in all climates.
