Am. Egret.— On July 17th, 1910, a 

 colony in which 64 nests were found 

 containing young and eggs in various 

 stages of incubation, being so late in

 birds must have been driven from 

 other localities.

 ridges between the waterways also in 

 the dry meadows adjoining. 



Double Crested Cormorant — Fre 

 quently seen flying inland, evidently 

 from Egg Island.

In Denver. 

 While in Denver early in July on a 

 short business trip it was our pleas- 

 ure to make the acquaintance of Mr. 

 J. D. Figgins the director of the Col- 

 orado Museum of Natural History. We 

 found him a very pleasant and enter- 

 taining gentleman and much inter- 

 ested in Ornithology. It was a satis- 

 faction to have him call attention to 

 his recent contribution to THE AUK, 

 Vol. XXXI No. 1, while discussing the 

 unfortunate drift of some ornitholo- 

 gists toward inflnitismal and unjusti- 

 fiable subdivision of species of birds 

 into alleged geographic races. Tliis 

 cur readers all know we abhor. 



We found a real up to date museum 

 and one that bore evidences of re- 

 cent and substantial grov/th and of 

 having a master mind at the head. —

 forth its shrill song but upon any 

 bright day of autumn or winter one 

 may chance to hear the wren's music 

 as it pauses to sing from a safe re- 

 treat. 



In Southwestern Pennsylvania this 

 Wren is quite an abundant species. He 

 flits about brush heaps, hops over 

 board piles, and scans every nook 

 and crevice in search of his favorite
