206 BIRDS OF OHIO. 
This kinglet is common as a transient, but less common 
as a winter resident. It is sometimes even abundant dur- 
ing the migrations in certain localities. The kinglets are 
leaf and twig gleaners, but also make sallies after flying in- 
sects. They are to be found among the evergreen trees dur- 
ing the winter more often than elsewhere, but also frequent 
well protected brushy woods to feed. Their food seems to 
be wholly insects. 
This kinglet goes north about the middle of April and re- 
turns again about the first of October.

Ruby-crowned Kinglet. 
Synonyms: Motacilla calendula. 
Ruby-crown, Ruby-crowned Wren, Ruby-crowned Warbler.

The Ruby-crowned Kinglet is rather more common 
during its migrations than the Golden-crowned, but it does 
not remain during the winter, nor is there any record of its 
breeding within the state. It is found in the same situations 
as the Golden-crowned, both appearing in our parks and 
orchards in spring and autumn. The Ruby-crowned has a 
louder voice than its cousin ,and may be more readily found 
on that account. The food is the same as that of the other 
species. 
This kinglet reaches Ohio about the middle of April and 
remains four weeks, returning about October 1 and pass- 
ing south in about three weeks.
