 that instinct could not have directed the newly 

 hatched and blind cuckoo to oust the hedge sparrow,

 old bird would have been sitting close on the nest, 

 but for the circumstance which forced her from it, 

 namely, the accidental presence of an intruder

 and the magpie, not forgetting the pheasant and the
