"1 Allison, Birds of West Baton Rouge Parish, La. A^*l 



31. Buteo borealis harlani. Harlan's Hawk. — I saw this species only 

 on March 12 and 16, 1903, while on the way to and from New Orleans ; 

 on these dates it was not uncommon. But from Port Allen, Lobdell, and 

 the districts west of these points, it was not recorded. 



32. Buteo lineatus. Red-shouldered Hawk. — Possibly both this 

 form and B. I. alleni -wqtq present ; certainly B. I. lineatus was. I found 

 it a common resident, beginning to nest in January. 



33. Archibuteo lagopus sancti-johannis. American Rough-legged 

 Hawk. — On two successive daj^s — April 6 and 7, 1903 — I saw at some 

 distance, beating over the fields, a large, light brown hawk which could 

 not have been anything but this species. 



34. Falco columbarius. Pigeon Hawk. — A not uncommon winter 

 resident. 



35. Falco sparverius. American Sparrow Hawk. — A very common 

 winter resident, subsisting very largely on grasshoppers. I saw more 

 after March 30, 1903. In common with certain others, this species regards 

 latitude less than other considerations in its choice of breeding-places ; 

 in sandy or clayey regions, wooded with conifers {Pinus tceda, P. australis, 

 et P. cubensis), it remains throughout the year in latitudes lower than that 

 of this parish. 



36. Pandion haliaetus carolinensis. American Osprey. — 1 saw a 

 single one sailing up the river May 15, 1903. 



37. Asio accipitrinus. Short-eared Owl. — I saw this species only 

 once ; this individual I flushed from a grassy ditch in a canefield, on 

 March 26, 1903. Subsequently I found remains of another. 



38. Syrnium varium. Barred Owl. — Writing to Dr. Fisher, of the 

 Biological Survey, for definite information as to the distribution of Buteo 

 lineatus alleni and Syrnium varium alleni, I was informed that it was Mr. 

 Ridgway's opinion that typical specimens could not be found outside of 

 the Florida peninsula. Therefore I refer the owls of this region to 5. v. 

 varium. This species is resident, and rather common in the deep swamp. 

 The swamps on the left bank of the river being denser, it is more com- 

 mon there. 



39. Megascops asio fioridanus. Florida Screech Owl. — A very 

 common resident in suitable localities — copses, and thick hedge-rows 

 containing trees. Very difficult to see, but very often heard. 



40. Coccyzus americanus. Yellow-billed Cuckoo. — A common 

 summer resident ; in 1903 it was very late in arriving in this parish, 

 though not abnormally so at New Orleans. None were present until May 

 8, but the next day the species was fairly common. 



41. Ceryle alcyon. Belted Kingfisher. — Remarkably uncommon. 

 None present during the winter, and one on March 28, 1903, and another 

 on April 5, were the only individuals I saw. 



42. Dryobates villosus audubonii. Southern Hairy Woodpecker. — 

 A common resident. 



43. Dryobates pubescens. Downy Woodpecker. — I have recorded
