68 Lincoln, Birds of the Clear Creek District] Colo. [j^. 



Asyndesmus lewisi. Lewis's Woodpecker. — Fairly common winter 

 resident and a few have been seen throughout the summer although I have 

 never known them to nest below the Yellow Pine zone in this section of 

 the State. 



Colaptes c. collaris. Red-shafted Flicker. — Abundant resident. 

 Usually mated before the winter snows have melted. 



Phalaenoptilus n. nuttalli. Poor-will. — Rare. One was repeat- 

 edly flushed September 21, 1907, but was not secured. Mr. Rett, however, 

 obtained a fine specimen May 20, 1917. 



Chordeiles v. henryi. Western Nighthawk. — Summer resident, 

 plentiful. Arrives about the first of June and frequently remains until the 

 first of October unless driven out by early storms. 



Aeronautes melanoleucus. White-throated Swift. — Rare. Noted 

 only during spring migrations, when a few will be observed flying toward 

 the mountains. 



Selasphorus platycercus. Broad-tailed Hummingbird. — Not com- 

 mon. Most of the hummers of this region seem to prefer the environs of 

 Denver where an abundance of flowers is assured throughout the summer. 



Tyrannus tyrannus. Kingbird. — Summer resident, common. Ar- 

 rives by the middle of May and is nesting by June first. 



Tyrannus verticalis. Arkansas Kingbird. — Summer resident; 

 rather more common than T. tyrannus. Arrives and nests about the same 

 dates. 



Myiarchus c. cinerascens. Ash-throated Flycatcher. — Rare. 

 A specimen taken from a willow thicket, September 17, 1911, and a report 

 of one seen May 26, 1912, by the late E. P. Schuetze, are my only records. 



Sayornis phoebe. Phcebe. — Rare. But one record; a specimen (the 

 second record for Colorado) was taken by Mr. F. L. Kemmerling, Septem- 

 ber 17, 1911, and is now in my collection (Coll. F. C. L. No. 454). 



Sayornis sayus. Say's Phcebe. — Summer resident, not uncommon. 

 Arrives early in April and generally selects deserted out-buildings or 

 bridges as nest sites. 



Nuttallornis borealis. Olive-sided Flycatcher. — Rare, migratory. 

 Mr. Rett reports two observed September 9, 1917, associated with a number 

 of Western Wood Pewees,' and one other secured May 17, 1918. 



Myiochanes r. richardsoni. Western Wood Pewee. — -Summer 

 resident; perhaps the most common of the small flycatchers. More 

 frequently heard than seen. 



Empidonax difficilis. Western Flycatcher. — Rare; seen and 

 taken only during August and September. 



Empidonax t. trailli. Traill's Flycatcher. — Summer resident. 

 From June 12 to 19, 1910, this flycatcher was very common and was evi- 

 dently nesting in the dense thickets of wild plum, although no nests were 

 found. Several specimens were taken. 



Empidonax t. alnorum. Alder Flycatcher. — Rare. A specimen
