OCT., 1900.] BIRDS OF THE YUKON REGION. 75 



had been feeding on marsh hawks, Alaska jays, white-winged cross- 

 bills, intermediate sparrows, and varied thrushes. 



I saw two duck hawks near Nulato August '24:, and a tame young 

 bird spent part of the rainy evening of August 30 perched on the back 

 of a chair in the hotel at St. Michael. The cere and bill of the young 

 male were french gray, changing to black on tip of bill and along 

 culmen and cere above; tarsi and toes, pale, grayish green; soles, tarsi 

 behind, and edges of scutella? in front, yellow; nails, black. 



83. Falco peregrinus pealei. Peale Falcon, 



One flew around the Corwin when we were some distance south of 

 the Aleutian Islands and out of sight of land October 7. 



84. Falco columbarius. Pigeon Hawk. 



We saw a pigeon hawk feeding on a large vole near Charlie Creek 

 August 8. Osgood took a young male at a point 12 miles aljove Circle 

 August 13, and I saw one at the Aphoon mouth August 28. 



85. Falco columbarius richardsoai. Richardson Merlin. 



At Circle August 18 I shot a young female merlin which is inter- 

 mediate between columharius and richardsonl. In general coloring 

 both above and below, it is between typical examples of the two 

 forms and approaches very closely a specimen of riclmTdsmiv taken by 

 Captain Bendire at Walla Walla, Washington, December 3, 1880, and 

 now in the American Museum of Natural History. My bird has light 

 spots on outer webs of primaries and six light bars on tail similar to 

 those of ricJiardsoni^ but the bars are narrower and more interrupted. 

 The crop and stomach contained the remains of a red-backed mouse. 

 The i rides were vandjdce brown; cere, greenish-yellow; maxilla, slate 

 black at tip, changing to greenish-white toward cere and pale french 

 gra}^ at commissure; mandible, pale dull greenish, changing to pale 

 french gray toward tip and commissure; tarsi and toes, straw yellow, 

 the latter inclining toward sulphur yellow; nails, black. Mr. Cant- 

 well writes in the 'Osprey'^ of having seen Richardson's merlin, but 

 does not state that he took specimens. These are the only records for 

 this bird in the Yukon Valley. 



86. Falco sparverius. American Sparrow Hawk. 



We saw this species at Log Cabin June l-l, Semenow Hills July 19 

 and 20, near the Tatchun River July 23, near Fort Selkirk July 26, 

 about 30 miles below Fort Selkirk July 28, and, I think, at Circle 

 August 15. We took specimens on July 19 and 28. This species has 

 not previously been reported from along the Yukon.
