might also have included this bird. In Bonaparte's edi- 

 tion of Wilson' s work (1834), the Mississippi river is given 

 as the eastern limit of their range, but now they are very 

 common hundreds of miles to the East of that stream, 

 and have even been seen at Washington (Ridgway) and

Transient. Very common. A few winter here, as I have

 An excessively abundant summer resident. It is proba-
