  e American robin is a much larger bird than the English  robin…redbreast and less brilliantly colored。 John Burroughs calls him; of all our birds; 〃the most native and democratic。〃
  How the robin dominates birddom with his strong; aggressive personality! His voice rings out strong and clear in the early morning chorus; and; more tenderly subdued at twilight; it still rises above all the sleepy notes about him。 Whether lightly tripping over the lawn after the 〃early worm;〃 or rising with his sharp; quick cry of alarm; when startled; to his nest near by; every motion is decided; alert; and free。 No pensive hermit of the woods; like his cousins; the thrushes; is this joyous vigorous 〃bird of the morning。〃 Such a presence is inspiriting。
  Does any bird excel the robin in the great variety of his vocal expressions? Mr。 Parkhurst; in his charming 〃Birds' Calendar;〃 says he knows of 〃no other bird that is able to give so many shades of meaning to a single note; running through the entire gamut of its possible feelings。 From the soft and mellow quality; almost as coaxing as a dove's note; with which it encourages its young when just out of the nest; the tone; with minute gradations; becomes more vehement; and then harsh and with quickened reiteration; until it expresses the greatest intensity of a bird's emotions。 Love; contentment; anxiety; exultation; rage  what other bird can throw such multifarious meaning into its tone? And herein the robin seems more nearly human than any of its kind。〃
  There is no one thing that attracts more birds about the house that a drinking…dish  large enough for a bathtub as well; and certainly no bird delights in sprinkling the water over his back more than a robin; often aided in his ablutions by the spattering of the sparrows。 But see to it that this drinking…dish is well raised above the reach of lurking cats。
  While the robin is a famous splasher; his neatness stops there。 A robin's nest is notoriously dirty within; and so carelessly constructed of weed…stalks; grass; and mud; 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。
