Habits. 



The Chickadee's habits of life also commend them as being 

 beneficial. They are usually found in small flocks of from six to 

 a dozen, of which the larger number are females. These often 

 mix with those of Goldfinches and Tree Sparrows, or are found in 

 company with a pair of Nuthatches, during the winter, but become 

 more independent as spring advances and there is an abundance 

 of bird life all about them. Over half of my specimens were 

 secured in bushes on low, damp, marshy ground, or along a creek 

 or roadside. They often descend to the ground in marsh land
