interwoven twigs, lined with leaves, and is built in trees or bushes, sometimes in 

 marshes. From five to fourteen eggs, or even more, are deposited by the several 

 birds. These are of a glaucous-blue in color, usually covered with a light chalky 

 crust. Their average size is 1.34x1.20. 



384. GROOVED-BILLED ANI. Crutophai/a nulcirostris Swains. Geog. Dlst. — 

 Lower Rio Grande Valley in Texas and Lower California southward to "Peru. 



The Grooved-billed Ani was formerly only known from Yucatan, Central and 

 South Alnerica. Between the years 1865 and 1871 it was discovered in Western 

 Mexico, and finally added to the fauna of the United States by Mr. George B. Sennett, 

 "Who shot an adult male on May 19, 1878, at Lomita Ranch, on the Rio Grande, which 

 is seven miles above Hidalgo. It has since been found breeding in chaparral near 

 Brownsville, Texas, and its nest and three sets of its eggs taken there are in the 

 Ralph collection in the U. S; National Museum. The eggs of this species range from 

 four to eight, usually five in number, and of the same color as those of the last 

 species. No peculiarity seems to he noted in the nesting of this species; no mention 

 is made of eggs being laid in one nest by several females, as is the case with G. ani, 

 and we would naturally expect the breeding habits of both species belonging to the 

 same genus to be very much similar. Colonel Grayson states that the nest is usually 

 built in a thorny tree or bush, at a moderate height, and composed of thorns and 

 dry twigs exteriorly, and lined with fibrous roots. He describes the eggs on the 

 outside of the shell as rough and white, the inside green. The birds, he remarks, 

 g.ssociate in small flocks of eight or ten, and are fond of picking ticks off the cattle. 

 Mr. Charles W. Richmond states that this species is very abundant in the vicinity 

 of Bluefields, Nicaragua. The heart of a thick thorny orange or lemon tree appears 

 to be their favorite situation, from four to seven feet from the ground, sometimes as 

 high up as fifteen feet. The nests like those of C. ani, are very bulky, conspicuous 

 structures, composed of dead black twigs, and the cavity proper is invariably lined 

 with green leaves. The nest is a voluminous structure, and while in its cavity may 

 be found eggs of the original builder, other eggs, undoubtedly the product of some 

 Intruder, are often found in its framework. The eggS' resemble those of the Ani so 

 closely that the same description will answer for both. The average measurement 

 of forty eggs in the U. S. National Museum is about 1.23x.94, the largest 1.32x.99 

 inches, the smallest 1.09x.86 inches.

The Ground Uuckoo, Chaparral Cock, Snake Killer or Paisano, as it is differently 

 called, is a curious long-tailed, chicken-like bird, noted for its swiftness of foot. It is 

 found in Texas, New Mexico, Arizona and California southward. In Southern Cali- 

 fornia, Mr. Shields states that this bird is abundant in the chaparral and sage bush 

 regions. Its favorite food consists of small lizards and snakes. It nests in low 

 trees, usually in the low branches of a cactus or in a thorny bush.. A nest before 

 me, collected in Lee county, Texas, by J. A. Singley, is a coarse structure made of 

 sticks. It was placed in a haw bush about eight feet from the groundi The struc- 

 ture is thick, and clumsy, with but a slight depression for the eggs. The latter are 

 deposited at intervals of several days, and a perfectly fresh egg is often found with 

 one on the point of hatching; or young birds of variaus sizes with partially incu- 

 , bated eggs in the same nest is of. common occurrence. Mr. Shields found eggs as
