marked over the entire surface with spots and blotches of pinkish brown, 

 which are somewhat heavier on the small ends. There are a few small 

 scattered markings of a darker brown. The third egg has markings of deep 

 brown slightly underlaid with purplish and with the heavier blotches on the 

 large end. The eggs measure 47 x 57, 46 x 59, and 47 x 58 mm. The nest 

 was placed 35 feet up in a white oak and was apparently a crow's nest hast- 

 ily fitted up by enlarging the surface outside and adding a lining of the in- 

 ner bark of wild grapevine and dead cottonwcod. Collection of John Lewis 

 Childs. 



II. Set of 3 eggs. Very slightly incubated. April 24, 1899. The 

 markings on all three eggs are small and rather light brown in color, cover 

 the entire surface, and are strikingly longitudinal in arrangement. The 

 nest was in a scraggly black oak, 30 feet from the ground, and composed of 

 sticks, stems, grasses, leaves, and pieces of white oak bark. The set is still 

 in the Jasper Brown collection and I have been unable to measure the eggs. 

 They would not differ essentially in measurements, however, from those of 

 the three sets given. 



III. Set of 3 eggs, incubated a little over one third. April 9, 1900. 

 Two of the eggs are marked with rather prominent brown blotches, princi- 

 pally on the larger ends, but with smaller markings of the same color flow- 

 ing off toward the small ends and besprinkling the entire surface. The 

 third egg is covered evenly throughout with fine longitudinal markings in a 

 few places with larger blotches of brown color, these overlaid in a few 

 places with larger blotches of brown. Size of eggs, 48x61, 49x60, 47x60 

 mm. Nest was in a scraggly black oak tree, 32 feet from the ground, com- 

 posed of sticks and steins, lined with leaves, grasses, rabbit and pocket go- 

 pher fur and hair of squirrels. Collection of John Lewis Childs. 



IV. Set of 2 eggs, slightly incubated. March 29, 1901. Both eggs 

 are marked over the entire surface with small brown spots, darker on one 

 than on the other, and tending, as on the other specimens, to run lengthwise 

 of the eggs. On one egg the distribution is even, on the other heavier at 

 the small end. Size, 46x61, 47x58 mm. The nest was in a scraggly, gnarled 

 burr oak, well made of sticks, stems, grasses, leaves, weed pith, some 

 rabbit fur, and feathers from Grouse or Bob-white. Height above ground 

 not given but doubtless, in this kind of tree, not much different from the 

 other four. Collection of John Lewis Childs. 



V. Set of 3 eggs, slightly incubated, April 10, 1902. This set is not 

 now before me but, as I remember, it is quite similar in size and coloration 

 to set III above. The nest was in the same white oak from which the first 

 set was taken on April 21, 1898. The birds had added leaves and grass and 

 many feathers. Collection of G. H. Messenger, Atlantic, Iowa.
