30 Messrs. Suerparp and WuiteEar’s Catalogue 
asserts that the jarring noise made by Woodpeckers is designed 
to drive insects from their lurking-places. 
3. P. minor (Lesser Spotted Woodpecker). l esp 
This species is pretty common at Campsey Ash in Suffolk ; 
and it also breeds in Helmingham Park in the same county. 
Mr. Hunt has frequently observed it in his garden at Norwich. 
Genus XXVI. Yuwnx. 
1. Y. Torquilla (Wryneck). 
In general Bewick’s figures are remarkable for their accuracy ; 
but that which he has given of the Wryneck is faulty : the beak 
is too long, the head too small; and, indeed, the whole figure 
represents the bird smaller than it really is. He has also made 
the legs too slender, for it has exceedingly stout ones. The 
Wryneck in fact is, as White observes, a very robust bird. 
Genus XXVII. SITTA. 
1. S. europea (Nuthatch). 
The Nuthatch is met with in great numbers at Campsey Ash. 
The great length of its hind toe, in addition to its use in 
assisting it to run up and down the trunks of trees, probably 
assists it in grasping and carrying away nuts. It generally 
breeds in the holes of trees made by the Picus viridis, which, 
being too large, it walls up with mortar to a proper size. It 
lays five, and often six eggs, and is so tenacious of its nest that 
the bird will retain its possession until the last. 
Genus XXVIII. CERTHIA. 
1. C. familiaris (Common Creeper).
