AND OOLOGIST. 



21 



note maturit.y, for on Oct. 9, 1888, I took a 

 youn<r bird in streaked plumage with the 

 "wax" well developed. Taking- tliis bird at 

 that time of the year I consider of unusual oc- 

 currence and must have been raised in the 

 vicinity as it was very young, pin feathei-s 

 showing in various places. It was taken in 

 the city, in company witli a flock of young 

 ( "edar birds. Possibly there may have been more 

 of i/(trntln.s among them, but I saw only this 

 one. 



The Waxwiugs generally leave us about the 

 middle of Marcb, but tliey have been known 

 to linger as late as the latter part of April.
