﻿184 Bird- Lore 



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 

 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 

 vary very greatly as to kind of trees selected and position in the tree. Sites 

 may be found in conifers and also in deciduous trees, and even in shrubbery. 

 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 buffy, 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 

 by his drollery and intelligence. There is certainly no more picturesque 

 sight in bird life than to see a flock of Jays in the fall of the year flying with 

 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 



Is the Blue Jay found in your locality during the entire year ? If not, whem 

 does it arrive ? When does it leave in the fall ? Give your opinion of the habits of the 

 Blue Jay — this must be the results of your own observations of the live bird. How many 

 different kinds of trees have you found Blue Jays nesting in ? Give location of each nest 

 and materials used in construction. Tell what you have personally observed about the food 

 of Blue Jays. Who was Linnfeus ? What made him famous ?
