that a heavy summer shower brings more robins' nests to the ground than we like to contemplate。 The color of the eggs; as every one knows; has given their name to the tint。 Four is the number of eggs laid; and two broods are often reared in the same nest。

Too much stress is laid on the mischief done by the robins in the cherry trees and strawberry patches; and too little upon the quantity of worms and insects they devour。 Professor Treadwell; who experimented upon some young robins kept in captivity; learned that they ate sixty…eight earthworms daily  〃that is; each bird ate forty…one per cent more than its own weight in twelve hours! The length of these worms; if laid end to end; would be about fourteen feet。 Man; at this rate; would eat about seventy pounds of flesh a day; and drink five or six gallons of water。〃


ORCHARD ORIOLE (Icterus spurius) Blackbird and Oriole family

Called also: ORCHARD STARLING; ORCHARD HANG…NEST

Length  7 to 7。3 inches。 About one…fourth smaller than the   robin。 Male  Head; throat; upper back; tail; and part of wings black。   Breast; rump; shoulders; under wing and tail coverts; and under   parts bright reddish brown。 Whitish…yellow markings on a few   tail and wing feathers。 Female  Head and upper parts olive; shading into brown;   brighter on head and near tail。 Back and wings dusky brown;   with pale…buff shoulder…bars and edges of coverts。 Throat   black。 Under parts olive; shading into yellow。 Range  Canada to Central America。 Common in temperate latitudes   of the United States。 Migrations  Early May。 Middle of September。 Common summer   resident。

With a more southerly range than the Baltimore oriole and less conspicuous coloring; the orchard oriole is not so familiar a bird in many Northern States; where; nevertheless; it is quite common enough to be classed among our would…be intimates。 The orchard is not always as close; to the house as this bird cares to venture; he will pursue an insect even to the piazza vines。 

His song; says John Burroughs; is like scarlet; 〃strong; intense; emphatic;〃 but it is sweet and is more rapidly uttered than that of others of the family。 It is ended for the season early in July。

This oriole; too; builds a beautiful nest; not often pendent like the Baltimore's; but securely placed in the fork of a sturdy fruit tree; at a moderate height; and woven with skill and precision; like a basket。 When the dried grasses from one of these nests were stretched and measured; all were found to be very nearly the same length; showing to what pains the little weaver had gone to make the nest neat and pliable; yet strong。 Four cloudy…white eggs with dark…brown spots are usually found in the nest in June。
