about 3 to 4 inches downward from the twigs on which it is suspended. 

 The outside diameter is usually about 4-4.5 inches; the inner cup is usually 

 about 3 inches deep by 2.5-3 inches outer diameter. The upper rim of 

 the nest is, however, somewhat contracted, and it is almost entirely con- 

 structed of thin, wiry grass; lined with softer substances like thistledown. 

 The eggs are 4 to 6 in number, ovate in shape, with a pale bluish white 

 ground color, overlaid with grayish or pearly. The markings consist of 

 blotches, spots, scrawls and pen blots of purple, brown and pearl gray, 

 heaviest about the larger end, forming more or less of a wreath, the darker 

 brownish and blackish tints predominating. The average dimensions of the 

 eggs are .82 by .57 inches. The song of the Orchard oriole is decidedly 

 different from that of our commoner Baltimore oriole. It is a more finished 

 effort, the voice rich and flexible with considerable expression. The song, 

 however, is uttered in a rather hurried manner as if the bird were restless 

 and implusive (Bendire). This bird is even more beneficial than the 

 Baltimore oriole as it rarely, if ever, is known to feed on green peas or 

 small fruits, so far as reported in this State, but subsists almost entirely 

 on caterpillars and rose bugs, beetles and plant lice.
