WINTER NEIGHBORS 147

 also left his winter- quarters in the spring. This, 

 then, appears to be the usual custom. The wrens 

 and the nuthatches and chickadees succeed to these 

 abandoned cavities, and often have amusing disputes 

 over them. The nuthatches frequently pass the

 and then disappeared. The big hairy usurper passed 

 a night in the cavity ; but on being hustled out of
