138 THE BIRDS OF NORTHAMPTONSHIRE 



other sites might be mentioned, and we once found 

 a nest of this bird in a bunch of dried herbs hanging 

 from a beam in an outhouse. One of the most 

 singular situations in which I ever met with a Tree- 

 Creeper's nest was in the foundation of a nest of the

 other British birds which cannot be strictly classed 

 as migratory species. This is a very lively and
