adjoining mountain slopes, and was noted also at Rio Hacha and 

 Valencia. Grasshoppers of several species, as well as the migrating 

 locust, are very common here, which probably accounts for the abund- 

 ance of the Sparrow Hawk, the food of which consists largely of these 

 insects.

Three specimens : Bonda and Punto Caiman. 



The Caracara is a common bird in the more arid portions of the 

 lowlands, especially around Cienaga Grande. Simons gives the fol- 

 lowing account of it as observed at Valencia: "Local name ' Cari- 

 care.' Frequents the extensive savannas at the foot of the Sierra; 

 flies very little and low, running about in the grass in search of lizards, 

 etc.; usually associated with cattle; said to seize sick lambs and young 

 goats." 



61. Milvago chimachima cordata Bangs and Penard. 



Milvago chimachima (not Polyborus chimachima Vieillot) Salvin and God- 

 man, Ibis, 1880, 177 (Valencia; habits). — Allen, Bull. Am. Mus. Nat. Hist., 

 XIII, 1900, 131 (Salvin and Godman's reference). 



Eight specimens : Bonda. 



These differ as stated by Messrs. Bangs and Penard (Bulletin 

 Museum of Comparative Zoology, LXII, 1918, 35) from a specimen 

 from Bolivia, presumed to be typical chimachima. Immature birds 

 bear dates between March 15 and April 12. 



Simons, who collected several specimens at Valencia, on the south 

 slope of the Sierra Nevada, says that its " local name [is] ' Garra- 

 patero' or ' Piopio,' from its feeding on the ticks (garapata) of cat- 

 tle, and from its peculiar cry of pi-i-o, pi-i-o. Frequents palm trees, 

 where it builds its nest. A young male which could scarcely fly I 

 knocked down with a stone." Mr. Smith met with it at Bonda, but 

 Mr. Carriker failed to find it in this region until his second visit to 

 Rio Hacha in July, 1920. The species has an extensive South Amer- 

 ican rangre.
