PASSERES — SYLVICOLIDiE — SYLVICOLA. 89 



The Yellow-crowned or Yellow-rump Warbler, or Myrtle-bird, ranges from Mexico to the 

 65th degree of north latitude. It is a common species, and reaches us about the beginning 

 of May, on its way to the north, where it breeds. On its return, it leaves us in November, 

 and some are even seen as late as the early part of December. In summer, it feeds on 

 caterpillars and insects which it takes on the wing ; in the autumn and winter, on berries 

 of^ the Juniper, and particularly the Myrtle-wax berries (Myrica cerifera), which has 

 given rise to one of its popular names. Eggs 4-5, flesh-colored, sparsely dotted with red 

 in a ring around the larger end. Extremely common in this State.

There has been great confusion in relation to this species, and more extended observations 

 are still requisite to render its history complete. The specimen in the State Collection was 

 shot, September 20, in the neighborhood of New-York. Although very abundant in the 

 Southern States from November to April, it has seldom been noticed in this State, where it 

 appears to be shy and solitary. Its breeding places and periods of migration are yet unknown. 

 It has been observed from Mexico to the 55th degree of north latitude.
