507. Baltimore Oriole. HANG-NEST, GOLDEN ROBIN. FR.—L’ORIOLE DE BALTIMORE 
Icterus galbula. L, 7:53. Plate XXVII B. 
Distinctions. Coloration. 
Field Marks. The striking flashes of golden orange and the rich contralto voice are 
absolute identification marks. |The species can only be confused with extralimital forms. 
Nesting. The nest of the Baltimore Oriole is one of the avian curiosities. It is in the 
form of a bag woven of fibres, plant down, hairs, and string and hangs from the end of long 
drooping branches. With her sharp, awl-like bill the female Oriole thrusts a fibre into the 
side of the nest, then reaching over to the inside pulls it through, tugging to make all tight 
and solid, another fibre is thrust in and the process repeated until when complete the nest 
is so knitted, woven, and felted together that though tossed at the end of long flexible 
whip-like branch tips through summer and winter storms, it remains intact for several 
years. 
Distribution. Eastern North America north to the bounds of dense settlement. 
Open country with scattered groves and occasional large isolated elms 
is the ideal habitat of the Baltimore Oriole. It obtains its name from its 
brilliant orange and black livery, the colours of Lord Baltimore, under 
whose patronage the state of Maryland was first settled and in whose 
honour the bird was named by the early settlers. 
Economic Status. 'The food of the Oriole consists mostly of insects, 
including, in order of numbers, caterpillars, click beetles, of which the 
pestilent wire worms are the larve, May beetles, and grasshoppers. Very 
few predaceous beetles are taken. The amount of vegetable matter is 
small. This species, therefore, ranks very high as an insect destroyer. 
Complaints are sometimes made that the Oriole spoils fruit and it has been 
accused of puncturing grapes for the juice. It is not the amount which 
it takes that is objected to but the quantity of fruit that is spoiled, for it 
goes from bunch to bunch puncturing many and consuming little. This, 
however, seems to be a very local and perhaps an individual habit and 
except in vine country is of comparatively small importance. In Canada, 
the Baltimore Oriole leaves shortly after mid-August and before the autumn 
fruit season is well advanced, so that grapes are usually too green to be 
attractive to it. Hence, though it cannot be wholly exonerated from the 
charges which have been made against it, the damage done by the Oriole 
in Canada has certainly been greatly exaggerated. The good the bird 
does is constant and important, the harm is occasional and slight. 
509. Rusty Blackbird. RUSTY GRACKLE. FR.—LE MAINATE COULEUR DE ROUILLE. 
Euphagus carolinus. lL, 9-55. About the size of a Red-wing, but all black with green 
reflections and with straw-coloured eyes. In the autumn the feathers are broadly edged 
with rusty, lighter on the crown and head. The female is a nearly evenly dark grey bird 
with traces of rusty marks in spring, much more extensive in both sexes in autumn when 
they form a well-defined, reddish cap and a light eyebrow line. 
Distinctions. Small size compared with the Crow Blackbird, the only other comparable 
species with light coloured eyes; even blackness or rusty overwash tending towards a light 
line over the eye, and straw-coloured eye. 
Field Marks. Size, coloration, and straw-coloured eyes. 
Nesting. In coniferous trees or on ground, in nest of grasses or moss. 
Distribution. Eastern and northern North America; usually breeding just north of 
the cultivated areas in Canada. 
The Rusty Blackbird visits us in great numbers spring and autumn, 
joining and forming a considerable part of the large flocks of mixed Black- 
birds that are seen about the fields and marshes. The name Grackle which 
is commonly applied to the two yellow (nearly white) eyed Blackbirds 
is doubtless derived from the sound of their harsh, crackling notes.
