APRIL AND MAY BIRD-LIFE AT GLEN ELLYN 'NEAR CHICAGO^ ILLINOIS Bv Benjamin T. Gault With the real opening of spring, which may take place here anywhere between the 15th and 25th of April, it is clearly observable that a new order of things is apparent on every hand, though we do not feel that the season is actually upon us until the hepatica and the little spring beauty have con- tributed their matchless charms to the yet incipient plant-life of our hitherto flowerless woods. Even then it is sometimes a question more undecided than otherwise when we carefully take into account the weather. The birds, too, offer us almost a parallel illustration when we stop to consider and study their ways. The largely insectivorous species, the true harbingers of spring, do not appear in anything approaching wave-like movements until about the closing days of the month, or when the rejuvenating in- fluences of milder weather have set into active motion the various forms of insect -life. Several species that have passed the winter with us, or made their appearance during the days of February and March, now make their exit for more northern breeding latitudes; and of rliis class we may mention the Tree Sparrow, Short-eared (^wl, Rough -legged Hawk. Junco and Fox Sparrow; also the Rusty Crackles, which have added so largely to the animated life of the woodlands during the earlier days of the month. At this period they are great ground -searchers for the several kinds of larva? snugly hidden beneath the dead and moistened leaves, and as they pass hither and thither in restless flocks through the woods, prospecting as they go, they present indeed a most interesting sight. (Jur early breeders, the Hawks and Owls, Crow, Jay ami W'hite-rumped Shrike, are covering well-advanced eggs by this time. In favorable seasons we may confidently look for the arrival of the Bobo- link, Baltimore Oriole and, possibly, the Rose -breasted Grosbeak, during
