THE CROW BLACKBIRD. 59 
Mr. C. J. Maynard repeats the charges of depredations in the corn- 
field, but contends that their trait of robbing nests of other birds is by 
far the worst damage they do. He says: 
They will visit the homes of those species which build in accessible situations and: 
deliberately remove the eggs or, what is more to be deplored, the helpless young and 
devour them in spite of the cries of the distracted parents who are powerless to pre- 
vent the outrage. * * * So frequently were these depredations committed upon 
the homes of the Robins and other birds, that built about my place this season, that. 
there was scarcely an hour in the day during early summer when I could not hear 
the warning cries of the adult birds, followed by the harsh, scolding notes of the 
Crow Blackbird as he was vigorously attacked on all sides, but he seldom retreated 
without accomplishing his purpose. Such continuous slaughter must greatly thin 
the ranks of the birds that are thus robbed and it will be safe to say that the Purple 
Grackles destroy more birds than all the other predatory species combined. * * * 
In Florida * * * they also eat avariety of food. In early Winter large flocks. 
may be seen on the tops of the palmettos, feeding on the fruit, and they also eat 
berries in their season. Later small flocks are found on the margin of streams, fre- 
quently wading into them in search of little mollusks, crabs, etc., and it is not rare 
to meet with one or two scattering individuals in the thick hummocks, overturning 
the leaves in order to find insects or small reptiles which they devour. I once saw 
one catch a lizard which was crawling over the fan-like frond of a palmetto, and fly 
with it to the ground. The reptile squirmed all the while in its frantic endeavors to 
escape, but the Blackbird held it firmly and, after beating it to death, removed the 
skin as adroitly as if accustomed to the operation, then swallowed the body.? 
Dr. B. H. Warren says as a result of his investigations of the food 
of the crow blackbird: 
In the wake of the plowman, as he turns the crumbling earth, closely follow the 
argus-eyed Grackles, ever on the alert to seize the wriggling worm, the agile beetle, 
or the glistening grub, and the numerous Jarvz thrown out as each furrow is turned. 
Certainly, at this season our sable acquaintances are engaged only in that which will 
prove of utility to the cultivator when his crops are growing. We repeatedly hear 
of how the blackbirds tear up and devour the young and growing corn. This, 
unquestionably, is sometimes the case, but I am confident that the destruction thus 
done is much exaggerated. I am aware that on more than one occasion I have seen 
the tender blades of corn lying on the ground where were actively at work Crow 
Blackbirds, a number of which were shot, and on a post-mortem dissection their 
stomachs revealed almost entirely insects. Some six years ago I was visiting a friend 
who had thirty-odd acres of corn (maize) planted. Quite a number of ‘“‘blackies,”’ as 
he styled them, were plying themselves with great activity about the growing cereal. 
We shot thirty-one of these birds feeding in the corn field. Of this number nineteen 
showed only cut-worms in their stomachs. The number of cut-worms in each, of 
course, varied, but as many as twenty-two were taken from one stomach. In seven 
some corn was found, in connection with a very large excess of insects, to wit: Beetles, 
earth-worms, and cut-worms. The remaining five showed chiefly beetles. * * * 
Strawberries, blackberries and other fruits are fed upon, but to a very limited 
extent, by this species. The diet of the young birds, while under parental care, is 
almost exclusively insectivorous, consisting mainly of caterpillars and grubs. 
It is a well-established fact that they are given to pillaging the eggs of other birds, 
especially the common Robin. Gentry, however, states that they destroy the young 
of birds, a fact, as yet, unobserved by the writer.’
