gulls. One bird only was seen while on Isabella Island, but after watching 

 him chase a Tropic Bird for some time he made off for the distant Tres 

 Marias Islands and was soon lost to sight. 



43. Falco sparverius subsp? Sparrow Hawk. — Two females 

 were secured in Tepic. April 1. A pair were also generally found on a 

 dead palm tree stump on the banana ranch where they had had their nest 

 the previous season. 



44. Polyborus cheriway. Audubon's Caracara. — A number of 

 pairs were seen on the mainland between the rancho and San Bias. They 

 permitted one to come within twenty feet of them before taking wing. 



45. Polyborus cheriway pallidus. Tres Marias Caracara. — 

 These birds were very abundant on White Rock during my stay, and also 

 on Cleofa Island where they bred. 



46. Screech Owl. — A single bird of some species of Screech Owl 

 was flushed from a cavity on Isabella Island, and although I followed it 

 for some distance I was unable to bring it down. 



47. Horned Owl. — Some species of Horned Owl was heard one 

 night from the porch of the ranch house by both Mr. Bryant and myself, 

 but I was not able to secure it. 



48. Glaucidium phalsenoides. Pygmy Owl. — The pair of birds col- 

 lected occupied a woodpecker hole in a dead palm stump at the side 

 of the ranch house, and after waiting some little time till I was sure from 

 their actions that they had laid, I cut the hole open April 19. Instead 

 of eggs I found the hole half full of shelled corn, the little fellows having 

 picked it up at night from the ground outside the kitchen where the cook 

 had been sorting it before making torteas. I then gathered in the pair 

 and found no sign of breeding when dissecting them. Several other pairs 

 were seen around the rancho, especially in the dense thickets back of the 

 house, and they seemed to be able to get around in the bright sunlight as 

 well as any other bird. 



49. Amazona finschi. Finsch's Parrot. — These birds were very 

 common around the rancho and their noisy squeak could be heard the 

 last thing before dark and the first thing in the morning as they passed 

 back and forth from the wild fig trees where they were feeding. The palm 

 trees seemed to be their favorite nesting places, and a set of three pure 

 white eggs, about the size of a Belted Kingfisher's, were secured the last 

 week in March. None of this species were noted at San Bias, some eight 

 miles away. 



50. Amazona albifrons. White-fronted Parrot. — This species 

 was very common around the town of San Bias only, none being seen 

 over at the ranch some eight miles away. During the hot part of the day 

 they kept to the palms growing within the town, while in the late afternoon 

 and early morning they could be found feeding in the bushes and trees on 

 the outskirts of the town. 



51. Amazona oratrix. Double Yellow-headed Parrot. — This
