THE OOLOGIST. 



Incubation well begun. Size of egg 

 1.64x1.30. 



No. 5. — Two eggs taken June 10th 

 from horizontal limb of white elm, 

 six miles southeast of Heman, Woods 

 County. Nest twenty feet from ground, 

 composed of coarse sticks, quite flat, a 

 spare lining of green elm leaves. Birds 

 at nest. Incubation half over. Size of 

 eggs 1.67x1.30 and 1.70x1.33. 



No. 6.— One egg taken June 10th 

 from horizontal limb of elm, six miles 

 southeast of Heman. Nest fifteen feet 

 from the ground, built like that of No. 

 5. Birds at nest. Incubation begun. 

 Size of egg 1.57x1.31. 

 No. 7.— Two eggs taken June 10th from 

 the top fork of cottonwood tree, six 

 miles southeast of Heman. Nest 

 thirty-five feet from the ground, built 

 of sticks, laid on top of some old nest 

 and lined with fresh cottonwood leaves 

 and seed pods. Birds at nest. Incu- 

 bation advanced. Size of eggs 1.50x1.26 

 and 1.68x1.38, an odd looking set, as 

 one egg appears one-half larger than 

 the other. 



No. 8.— Two eggs taken June 10th 

 from fork of cottonwood tree, six miles 

 southeast of Heman. Nest thirty feet 

 from the ground, built of sticks, lined 

 with green cottonwood leaves. Birds 

 at nest. Incubation begun. Size of 

 eggs 1.54x1.31 and 1.72x1.29. This last 

 egg is a freak, as it is positively 

 pyriform in shape, instead of the 

 rounded oval, typical of these eggs. 



No. 9.— One egg taken June 10th 

 from the fork of an elm tree, eight 

 miles southeast of Heman. Nest 

 twenty feet from the ground, composed 

 of sticks, lined with cottonwood seed 

 pods, which were ripe and bursting. 

 Birds at nest. Incubation fresh. Size 

 1.59x1.27. 



No. 10.— Two eggs taken June 10th 

 from an elm tree, eight miles south- 

 east of Heman. Nest eighteen feet 

 from the ground, made of sticks, 

 lined with fresh leaves of elm and 



sumac. Birds at nest. Incubation 

 begun. Size 1.59x1.30, 1.55x1.29. The 

 eggs in this set are nicely matched as 

 to size and shape. 



No. 11. — One egg taken June 12th 

 from upper forks of "Black-Jack" 

 oak, two miles northwest of Walthall, 

 Woods County. Nest fifteen feet from 

 the ground, composed of sticks, lined 

 with a few leaves from same tree, 

 nearly fresh. Incubation fresh. Size 

 1.55x1.32. 



No. 12. — One egg taken June 13th 

 from "Black-Jack" oak, two miles 

 north of Walthall. Nest nineteen feet 

 from the ground, composed of coarse 

 sticks and lined with fresh sumac 

 leaves. Incubation begun. Size 

 1.73x1.41. Very large. Looks much 

 like a rounded egg of Marsh Hawk. 



No. 13.— One egg taken June 20th 

 from fork of large limb of "Black- 

 Jack" oak, at Pawnee, Pawnee County, 

 Oklahoma. Nest twenty-five feet up a 

 very flat structure of a few twigs, lined 

 with small twigs with green leaves on. 

 Incubation begun. Size of egg 

 1.62x1.34. This egg was very heavily 

 stained and quite smooth from incu- 

 bation. I think incubation must have 

 been further advanced than Mr. 

 Stevens' notes would indicate. Many 

 of the stains on this eggwould suggest 

 markings, and I think it must have 

 been an egg like this that gave rise to 

 the statement in Coues key that the 

 eggs are sometimes faintlj' marked. 

 I never saw an egg of this bird that I 

 thought was marked when deposited. 



No. 14. — Two eggs taken June 10th 

 from horizontal limb of elm, eight 

 miles southeast of Heman, Woods 

 County. Nest fifteen feet from the 

 ground, composed of sticks, lined with 

 green cottonwood leaves. Incubation 

 advanced. Size of eggs, 1.71x1.33 and 

 1.68x1.41. 



No. 15. — Two eggs taken by J. M. 

 Rutledge from "Black Jack" oak, one 

 mile northwest of Walthall, on June
