he shot one during a hard snow-storm on Lock's Lake, one of the Barr 

 Lake Chain. 



[188. Mycteria americana. Wood Ibis. — Migrant ; rare in near-by areas. 

 (?-Aug. 30.) A southern species wandering into Colorado occasionally 

 in summer. Cooke speaks of one in the Maxwell collection at Boulder. 

 (Birds of Colo., p. 60.) The writer recorded two more specimens that were 

 shot by L. L. Llewellyn, Aug. 30, 1902, at a small lake about 12 miles south- 

 west of Denver. (Auk, XX, 1903, p. 65.) Mr. George Suess informs me 

 that in about 1896 or 1897 he saw a flock of perhaps a dozen birds, which 

 appear to have been of this species, at Patrick's Lake, near Littleton.] 



190. Botaurus lentiginosus. American Bittern. — Summer resident; 

 or resident. In summer, common; in December, rare; in migration, com- 

 mon. I speak of it as a possible resident on the strength of one record, a 

 specimen seen by myself Dec. 28, 1904, at one of the warm springs on the 

 Platte River near Fort Morgan. It appeared to be perfectly sound, being 

 a strong flyer. I have eggs collected June 21, that were but slightly 

 incubated. 



[191. Ixobrychus exilis. Least Bittern. — Migrant, or summer resi- 

 dent; very rare in near-by localities. (June 8, only known date.) Cooke 

 records but six specimens for Colorado and two of these are from Denver 

 and vicinity, the one being reported by H. G. Smith, and the other having 

 been killed by Rudolph Borcherdt, at Berkeley Lake, June 8, 1898. (Birds 

 of Colo., pp. 157, 197.)] 



194. Ardea herodias. Great Blue Heron. — Summer resident. 

 (March 20-about Sept. 24.) In migration, abundant; in summer, abun- 

 dant, locally. Abundant in summer along the Barr Lake Chain, to which 

 many are accustomed to fly in from the Platte River in the early morning 

 to feed upon fishes, etc., flying back again to roost presumably in the 

 river timber at night. They appear here in flocks containing as high as 

 two hundred birds. So far as known, they breed in this area only in tree-6. 

 A number of their heronries have been found within this area, among them 

 being one on the Cache la Poudre River near Windsor, Weld County; one 

 on Crow Creek, northeast of Greeley (Markham, Univ. Colo. Studies, Vol. 

 IV, p. 155 and plate ii, fig. 2.); and two noted several years ago by the 

 writer, the one on the Platte River near Henderson, the other on the same 

 river near Masters. Whether these last two heronries are still used by 

 the herons, I cannot state. 



197. Egretta candidissima. Snowy Egret. — Migrant; not rare. 

 (April 3-Sept., Salida.) A southern species that comes into Colorado in 

 summer regularly in small numbers and strings northward as far as Buffalo, 

 Wyoming, where, I have been told, a specimen was shot by James Dowlin 

 about April 11, 1904. The most northerly record within this area that 

 I have comes from La Salle, where C. A. Kendrick reports that two or 

 three have been shot on their club lakes. I have, aside from the two or 

 three mentioned above as being reported by Mr. Kendrick, twenty-six 

 additional records of this species for the State, ranging from the plains to
