﻿The Blue Jay 183 



the most trivial evidence, but every time it is repeated it gains in strength 

 and is soon magnified into huge proportions ; and what might have been easily 

 explained at the outset, by a careful examination into the facts, casts a life- 

 long slur on the character of an innocent victim. Even so careful and exact 

 a writer as the late Major Bendire is compelled to add, from his strict sense 

 of justice, that he had "never caught a Blue Jay in mischief." The writer's 

 experience with this bird is exactly parallel with that of Major Bendire, and 

 he is therefore loth to believe all the bad stories that have been printed about 

 the noisy, handsome Jay. In every village there is some boy who is not bad 

 at heart, but is so full of animal spirits and life that whenever an act of 

 harmless mischief is perpetrated it is immediately charged to him. This is 

 very much the case with the Jay, "whose obtrusive actions attract attention 

 when other birds, equally abundant, remain unnoticed." 



Probably the most accurate brief respecting the Blue Jay's feeding 

 habits that has ever been written is by Mr. F. E. L. Beal.* A few extracts 

 will show that much that has been written will not bear the scrutiny of 

 exact scientific research. After citing three cases of field observers who saw 

 Blue Jays in the act of sucking eggs or taking young birds, Mr. Beal adds: 

 "In view of such explicit testimony from observers whose accuracy cannot 

 be impeached, special pains have been taken to ascertain how far the charges 

 were sustained by a study of the bird's food. An examination was made of 

 292 stomachs collected in every month of the year, from 22 states, the dis- 

 trict of Columbia, and Canada. The real food is composed of 24.3 per 

 cent of animal matter and 75.7 per cent of vegetable matter. The animal 

 food is chiefly made up of insects, with a few spiders, myriapods, snails and 

 small vertebrates, such as fish, salamanders, tree-frogs, mice and birds. 

 Everything was carefully examined which might by any possibility indicate 

 that birds or eggs had been eaten, but remains of birds were found only in 

 two, and the shells of small bird's eggs in three of the 292 stomachs. One 

 of these, taken on February 10, contained the bones, claws and a little 

 skin of a bird's foot. Another, taken on June 24, contained remains of a 

 young bird. The three stomachs with birds' eggs were collected in June, 

 August and October. The shell eaten in October belonged to the egg of 

 some larger bird like the Ruffed Grouse, and, considering the time of the 

 year, was undoubtedly merely an empty shell from an old nest. Shells of 

 eggs which were identified as those of domestic fowls, or some bird of equal 

 size, were found in 11 stomachs collected at irregular times during the year. 

 This evidence would seem to show that more eggs of domestic fowls than 

 of wild birds are destroyed, but it is much more probable that these shells 

 were obtained from refuse heaps about farmhouses. t 



To reconcile such contradictory evidence is certainly difficult, but it

t The writer knows of a case where Blue Jays are frequent visitors to a garbage vessel close by a kitchen door, 

 even in summer, when other food is abundant.
