Capture of rare Bird? at Riverdale, N. Y. — Among the, 
rare and accidental avian visitors which have come under my observation 
as having occurred at Riverdale, N. Y., it may be well to note the fol- 
lowing : — - 
Tyrannus verticalis. „ Arkansas Flycatcher. — A young male, in 
somewhat worn plumage, taken on October 19, 1875, furnishes the third 
extra-limital eastern record of the species, and the first for New York 
State. The bird was first observed on the afternoon of the day previous 
to its capture, pursuing- its avocation of insect-hunting from the topmost 
branches of some tall trees near a private residence, and the following day 
was again found about the same spot and without much difficulty secured. 
I s stomach contained parts of a small beetle and partially digested berries 
of Ampelopsis quinquefolia, the latter also often forming the principal food 
supply of its congeneric species, T. carolinensis, during the last few days 
of its northern stay.
