and winter visitant. One stayed nearly all winter several years ago, 

 Krider Hawk (Buteo borealis hrideri). On March 25, 1914, I 

 identified this subspecies. Its tail had the lighter colored portions 

 almost white. 



Rough-legged Hawk (Archibiiteo lagopns sancti-johannis). Speci- 

 men in the Smith collection. 



Golden Eagle {Aquila clirysaetos) . Specimen in the Smith col- 

 lection, but which was taken in Ida county. 



Bald Eagle (Halkcetns leucocephalus leucocephalus) . A specimen 

 in the Smith collection which was taken In Crawford county. Mr. 

 Lee said, " Bald eagles used to nest, the last nest being in 1871, 

 at Brown's grove, near the north line of the county in Delaware 

 township. They were always rare, six in one day being the highest 

 usual record, but forty-two were seen in one tree about 1868." 



Duck Hawk (Falco peregrinus anatum). I saw one of these 

 hawks in the " Goosepond " April 16, 1916, obtaining a good look 

 at it. 



Pigeon Hawk (Falco columbarius cohim'barius). Mrs. George 

 May reported seeing two, which she had under close observation 

 for some time, near Herring, in the spring of 1911. 



Sparrow Hawk (Falco sparverius sparverius). Specimen in the 

 Smith collection. A rare migrant and still rarer as a nesting 

 species. Dates of first arrival are from March 24th to April 23rd. 

 A few miles south of Odebolt I saw four young only recently from 

 the nest and attended by the parents, July 28, 1913. On June 6, 

 1916, I found a pair nesting in the south Chicago & Northwestern 

 railroad bridge over the Boyer river. The nest was placed back in 

 the top of the high wooden structure, so I could not see the young, 

 but I could hear them calling, while the old bird swooped about 

 my head crying, " killy," " killy." 



Osprey (Pandion lialicetus caroUnensis). Mr. Lee said that the 

 osprey was only tolerably common, but that they were seen every 

 spring. I saw two at Wall lake May 14, 1916. 



Barn Owl (Aluco pratincola) . Specimen in the Smith collection. 

 Mr. Smith stated that this was the only one he ever saw. 



Long-eared Owl (Asio wilsonianus) . Specimen in the Smith col- 

 lection. It is of rare occurrence. I identified one October 20, 1908, 

 and have seen only two since. It is probably more common in the 

 timber along the Coon river. 



Short-eared Owl (Asio flammeus). Specimen in the Smith col- 

 lection. This species is a rare breeder and at times an abundant 

 winter resident. One February afternoon I counted seventeen fly- 

 ing about over the snow-covered earth, searching for meadow 

 mice. A pair usually nest in every fair sized patch of slough grass. 

 I saw a pair in the " Goosepond " several evenings in the summer
