This active little crested bird is a northern species, and reaches this State from the north 
in November, frequently staying with us the whole winter. The greater number, however, 
appear about the middle of April from the South ; but after a very short stay, pursue their 
journey northward. Nothing is known of its incubation, and little of its habits, except that 
it feeds on small seeds, on insects which infest trees, and their lurking larvae. Geographical 
range between 24° and 70° north latitude.
