RUBY-CROWNED (OR CRESTED) KINGLET. 
Regulus calendula. 
Much like the preceding, except that it is a trifle larger, the olive- 
green of the back is darker, and the crown is as follows: general color 
olive-green, a vermilion patch in the centre, and the forehead light 
gray. Length, 4.40 inches. 
Migratory. The habits of the Ruby-crowned Kinglet differ somewhat from those 
of its congener. 
It has a more southerly range, and spends its Winters in the south. It comes to us 
the middle of April, remains about one month, and then follows its Golden-crowned name- 
sake. Whether or not it goes as far north, | do not know, but it is not again seen here 
until late in September. At this time, and about two weeks in advance of the Golden- 
crown, it pays us a month's visit, when it finally departs for its southern Winter home. 
Dr. Mearns points out that this Kinglet ‘‘is one of our earliest singing migrants,” and 
remarks that ‘‘its song is one of the sweetest, and much louder than would be supposed, 
coming from such a little bird.”
