where its near ally loves to congregate with snow- 

 birds, for the refuse-matter of the kitchen. 



The topmost boughs of the tallest trees in its 

 natural haunts, are its delight, because there it is 

 out of danger, and can feed upon the eggs, larvae 

 and small insects which are found in creviced

 and can be approached only with great difficulty. 

 In quest of food, its movements are imitative of 

 the Certhiidtz and Muscicapidce. Being very agile, 

 it moves along the branches with facility, now above

 of birds, is chiefly noticeable during the spring 

 and autumn, when the tide of migration has set 

 northward. There are but few of our permanent 

 residents that are thus addicted. We have ob-

 regarded as eminently gregarious in certain 

 quarters, are gradually losing this tendency, and 

 usually pass the winter in flocks of a half dozen
