The Blue Jay 
seems evident that these nest -robbing propensities are not so general as has 
been heretofore supposed. If this habit were as prevalent as some writers 
have asserted, and if it were true that eggs and young of smaller birds con- 
stitute the chief food of the Blue Jay during the breeding season, the small 
birds of any section where Jays are fairly abundant would be in danger of 
extermination. Insects are eaten in every month in the year. The great 
bulk consists of beetles, grasshoppers and caterpillars. The average for the 
year is 23 per cent, but in August it reaches 66 per cent. Three-fourths of 
the Blue Jay’s food consists of vegetable matter, 42 per cent of which con- 
sists of ”mast,” under which are grouped large seeds of trees and shrubs, 
such as acorns, chestnuts, beechnuts, chinquapins, and some others. Blue 
Jays prefer mast to corn, or indeed any other vegetable food, for they eat 
the greatest amount at a time when fruit, grain and other things are most 
abundant. The Blue Jay gathers its fruit from Nature’s orchard and vine- 
yard, and not from man’s; corn is the only vegetable food for which the 
farmer suffers any loss, and here the damage is small. In fact, the exami- 
nation of nearly 300 stomachs shows that the Blue Jay certainly does far 
more good than harm.” 
The Blue Jay has an extensive range, being found in eastern North 
America as far north as latitude 52, and, casually, a little further; it extends^ j 
westward to about 100 west longitude, in Assiniboia, and south to about 
97 west longitude in northern Texas. It breeds throughout its range, but 
in winter most northern birds move southward. In Florida, and along the 
Gulf coast to southeastern Texas there is a slightly smaller race, but the ^ 
ordinary observer will not be able to note any difference. The nesting places tii 
vary very greatly as to kind of trees selected and position in the tree. Sites t 
may be found in conifers and also in deciduous trees, and even in shrubbery, ij 
The nest is usually bulky, but compactly built of twigs, bark, moss, leaves 
and various other materials. A set of eggs varies from 4 to 6; the color is 
greenish or huffy, irregularly spotted with shades of brown or lavender. 
As parents. Blue Jays are patterns. Whatever may be their reputation ! 
regarding the young of other birds, there is no question regarding their 
extreme solicitude for their own offspring.* 
Do not form your opinion about the Blue Jay from printed stories, but 
study this fascinating fellow for yourself and you will surely be captivated tl 
bv his drollery and intelligence. There is certainly no more picturesque de 
sight in bird life than to see a flock of Jays in the fall of the year flying with qg 
outspread tails, from one nut tree to another, screaming and calling to each 
other at the tops of their voices, or darting here and there among the gor- 
geously tinted foliage. 
Questions for Teachers and Students 
J 
Is the Blue Jay found in your locality during the entire year? If not, whei!;j)i 
does it arrive? When does it leave in the fall? Give your opinion of the habits of tin 1 
Blue Jay — this must be the results of your own observations of the live bird. How man}! 
different kinds of trees have you found Blue Jays nesting in ? Give location of each nes . 
and materials used in construction. Tell what you have personally observed about the fooc | 
of Blue Jays. Who was Linnaeus? What made him famous ?
