same county, and I found them in La Plata 

 County also. Mr. Aiken noted it at Caflon 

 City and Mr. Allen at the "Garden of the 

 Gods." 



156. TrochUus alexandri (Bourc and Muls.). 

 Black-chinned Hummingbird. Noted by Drew 

 and myself. Very abundant in southwestern 

 Colorado. 



157. Trorhilm platycercux (Swuui^.). Broad- 

 tailed Hummingbird. Reported by Anthony 

 as an accidental visitant. Reaches 13,000 feet 

 in summer according to Drew, and breeds 

 from 4,000 to 11,000 feet. I enter it as a sum- 

 mer visitant; tolerably common. (La Plata 

 County.) 



158. TrochUus rnfitx (Gmel.). Rufous Hum- 

 mingbird. Noted by Drew at 15,000 feet. 

 Breeds; rare (?). 



159. Tyrannm tyrannus (Linn.). Kingbird. 

 Common summer visitant east of the moun- 

 tains. 



IHO. Tyramnis verticalis (Say.). Arkansas 

 Kingbird. Common summer visitant from 

 eastern portion into the mountains and up to 

 7,000 feet. I saw two individuals only at 

 8,500 feet. 



161. Tyrnnn'is tocifemn.s (Swains.). Cas.sins 

 Kingbird. Observed by Drew, Beckham at 

 Pueblo, and by Messrs. Allen and Brewster, 

 the latter gentlemen saw it in company with 

 the preceding. 



162. Myiarchu.'i rinerasreus (Lawr.). Asli- 

 throated Flycatcher. Reported by Capt. 

 Thorne from eastern Colorado, also by Drew 

 and Brenninger. The eggs are usually live, 

 but four and six are often found. Found as 

 far north as the Black Hills in Wyoming. 

 Breeds in Colorado at 7,000 feet. 



16?.. Sayornis my a (Bonap.). Say's Phoebe, 

 Summer visitant; common in plains districts, 

 tolerably common near the mountains. Breeds 

 in small numbers as high as 8,000 feet. Nest- 

 ing habits similar to .S. phcebe (Lath.), but 

 eggs larger. 



164. Contopiis borealU (Swains.). Olive- 

 sided Flycatcher, Summer visitant and toler- 

 ably common in mountainous districts where 

 it breeds at 12,000 feet. I find many quota- 

 tions of this species in Colorado, but I have 

 not been informed if its eggs have been talcen. 

 The eggs in my collection are not with me, 

 so I am unable to give a description of them. 



165. Contoims pertinaz {Qah.). Cones" s Fly- 

 catcher. Reported by Capt. Thorne from the 

 plains. Rather far north for this species ac- 

 cording to the habitat given in the A. O. U. 

 check-list. 1 enter it pending future investi- 



gation as a rare straggler, although I consider 

 it doubtful. 



166. Contojms richardsonii (Swains.). Wes- 

 tern Wood Pewee. Transient visitant; toler- 

 ably common. (Anthony). I found it a summer 

 visitant; breeding at 9,000 feet. Drew reports 

 it as higli as 11,000 feet in the breeding season. 

 Nest placed in the forks of saplings in pine 

 gulches and dry water courses. Eggs similar 

 to the eastern bird. 



167. Empidonax difficilis (Baird.). Baird's 

 Flycatcher. Reported by Capt. Thorne from 

 near Fort Lyon, as flaviventris, which is no 

 doubt a case of mistaken identity. The wes- 

 tern variety is the form found in Colorado. It 

 is reported by Drew as breeding from the 

 plains up to 10,000 feet. Mr, D. D. Stone* 

 reports the taking of its eggs in the state, I 

 quote him. " July 4, one set, four eggs, fresh. 

 Nest in bank of railroad at Murphy, two and a 

 half miles below here (Denver). Ground color 

 creamy white, witli line dots of black and 

 lilac, and larger spots of lilac, generally dis- 

 tinct, but in some places blended together and 

 tending to form a ring about the larger end. 

 Average, .60x.70. Nest mainly of moss inter- 

 woven with rootlets, grass and small pieces of 

 tow string." One of the parents of this set 

 was identified by Mr, Ridgway, Mr. Stone 

 also records another set of three eggs which 

 were found in a "cut bank of hard wash, in a 

 small cavity, almost entirely of roots, lined 

 witli a small quantity of grass. Outer diam- 

 eter, :i% inches; height, 2 inches; inner diam- 

 eter, 1% inches; depth, % inch. 



168. Empidoiwx puHilliis* (Swains.). Little 

 Flycatcher. Summer visitant; tolerably com- 

 mon; breeds. Reported by Capt. Thorne and 

 Drew. None of the other members have ob- 

 served it. Eggs, four.t 



160. Empidonax minimus (Baird.). LeastFly- 

 catcher. Reported by Drew at 8,000 feet. 

 This is the only record I am able to find. It 

 has been found in Kansas, Nel>raska, and Wy- 

 oming, and probably occurs rarely in Colorado, 

 although out of the habitat given it in the 

 A. O, U. code. 



170. Empidonax hainmondi {'K-a,ntufi.). Ham- 

 mond's Flycatcher. Reported by Drew. Sum- 

 mer visitant; breeds from plains to 8,000 feet. 

 It is very likely to occur commonly on the 

 western slope of the mountains and in the 

 northern portion of the state. It is somewliat 

 sti-ange it has escaped notice so entirely.

 t Mr. Trippe observed pusilhis and called it a bird of 

 the plains. [C. F. M.]
