164. Falco columbarius columbarius Linnaeus. 



Falco columbarius Linn.«us, Syst. Nat., ed. 10, I, 1758, 90. — Sharpe, Cat. Birds 

 Brit. Mus., I, 1874, 408. — Cherrie, Auk, IX, 1892, 328 (San Jose ; a 

 skin brought to Mus. Nac. by M. Carranza). — Salvin and Godman, Biol. 

 Centr.-Am., Aves, III, 1901, 119 (references cited). 



Hypotriorchis columbarius Lawrence, Ann. Lye. N. Y., IX, 1868, 134 (San 

 Jose [J. Carmiol].) — Frantzius, Jour. fiirOrn., 1869, 369 (C. R.). 



We have record of but two specimens of the Pigeon Hawk having 

 been taken in Costa Rica, one by Carmiol and one by Carranza. I 

 have never seen the bird in that country and I suppose that like other 

 migrant hawks it is only an occasional straggler into the higher parts 

 of the plateau region. 



165. Falco aurantius Gmelin. 



Falco aurantius Gmelin, Syst. Nat., 178S, 283 [ex Latham). — Sharpe, Cat. 



Birds Brit. Mus., I, 1874, 402 ( Bahia and Demerara). 

 Falco deiroleucus Salvin and Godman, Biol. Centr-Am., Aves, III, 1901, 117 



(Costa Rica [J. Carmiol]). 

 Hypotriorchus deiroleucus Lawrence, Ann. Lye. N. Y., IX, 1868, 135 (La 



Palma [Zeledon]). — Frantzius, Jour, fiir Orn., 1869, 369 (La Palma). 

 This rare bird has not been taken in Costa Rica in recent years, and 

 its presence on this list lies wholly on the two records cited above. 

 Zeledon secured it at La Palma sometime prior to 1868, as recorded by 

 Lawrence, while Frantzius' record is undoubtedly based on the same 

 specimen. Salvin and Godman evidently secured it from Carmiol, 

 but no locality is given. At best it can be classed as only a very rare 

 straggler. 



166. Cerchneis sparveria phaloena (Lesson). 



Tinnunculus phaloena Lesson, Compl. Oeuv. Buffon, XX, 1847, 178 (Mexico).

 juela, Cartago). — Cherrie, Auk, IX, 1892,328 (San Jose, not resident in any 

 part, Oct. 1 to Feb. 28). — Underwood, Ibis, 1896, 446 (Miravalles). 



Tinnunculus sparverius Lawrence, Ann. Lye. N. Y., IX, 1868, 134 (San Jose 

 [Carmiol]). — Frantzius, Jour, fiir Orn., 1869, 369 (C. R. ). — Nutting, 

 Proc. U. S. Nat. Mus., V, 1882, 403 (La Palma de Nicoya, not common). — 

 Ridgway, Proc. U. S. Nat. Mus., V, 1882, 498 (Irazu [Nutting]); p. 502 

 (San Jose, abundant [Nutting] ). — Salvin and Godman, Biol. Centr.-Am.,
