Mtoli. 1891 Notes. 

 ' ;.a Swales, 



May 24. H. AUis and I went collecting 

 in the swamps near Voight's woods. 



Olive-backed Thrush ; I found two nests 

 containing four eggs each. The nests were 

 in low bushes, and were shrouded over with 

 green leaves, and were very pretty structures ; 

 each contained a Cowbird's egg. I never 

 found any nests of this Thrush before.

1. Hylocidda UKl/alata siwiinsoni (Cabaii), 

 Kidgw. Olivf-backed Thrush. I took a nest 

 with thr<!<3 eg-gs, supposed to bo of this species, 

 bur, a.-< it was in the post and near where a sen- 

 try was Plationed, I. dared not fire my gun, as 

 by so doing- I was lial)le to alarm the garrison, 

 and perhaps spend the balance of the day in tiie 

 post guard-house. The nest was placed upon 

 'some dead bushes hauging over a small slug- 

 jgisli stream, two feet above the water, nest of 

 i grass and leaves which were moist, and so 

 'loosely constructed as to nearly fall to pieces 

 when I removed it. Eggs with ground color, 

 dark-blueish, and I should say spotted, not 

 speckled, as the spots were large and almost 

 entirely covered the ground color. I am sorry 

 I to be obliged to begin this list with such a 

 doubtful species, but I enter it with the above 

 remarks, for what it is worth. Found up to 

 9000 feet. O.&O. XIII. May. 1888 p. 70 



Notes- Eggs of Thrushes &Thra8he#^

Olive-backed Thrush {HijlociMa ustulala 

 swaiusoni) . Possibly breeds in the mountain- 

 ous portions of Pennsylvania, but its liabitat 

 is Massachusetts and northward. Eggs of this 

 species riui through all the varieties exhibited 

 in a series of the Kusset-back, and no rule can 

 be laid down for ijroperly distinguishing the 

 eggs of these birds in the cabinet. Eggs com- 

 monly four, rarely five, and sometimes three. 



A set collected at Grand Manan, N. B., June 

 18, 1884, was taken from a nest in a spruce tree 

 three feet from the ground. Eggs bright blu- 

 ish green, specked all over with r-eddish brown, 

 quite pointed, .00 x .63 ; .89 x .64 ; .90 x .63. 



Another set collected .June 11th, 1877, also at 

 Grand Manan, N. B., the nest which was made 

 of roots etc., in a hollow stump about five feet 

 from the ground, has four eggs: .94x.70; .94 x 

 .71 ; .96x .71 and .96 x .69. Pale bluish, spotted 

 with reddish brown, chiefly at the larger end. 

 In three of the eggs the markings form an in- 

 distinct wreath at the larger end.
