LIKE a bit of sky this little harbinger of spring appears, as we see him and his mate househunting in early March. Oftentimes he makes his appearance as early as the middle of February, when his attractive note is heard long before he himself is seen. He is one of the last to leave us, and although the month of November is usually chosen by him as the fitting time for departure to a milder clime, his plaintive note is quite commonly heard on pleasant days throughout the winter season, and a few of the braver and hardier ones never entirely desert us. The Robin and the Blue Bird are tenderly associated in the memories of most persons whose childhood was passed on a farm or in the country village. Before the advent of the English Sparrow, the Blue Bird was sure to be the first to occupy and the last to defend the little box prepared for his return, appearing in his blue jacket somewhat in advance of the plainly habited female, who on her arrival quite often found a habitation selected and ready for her acceptance, should he find favor in her sight. And then he becomes a most devoted husband and father, sitting by the nest and warbling with earnest affection his exquisite tune, and occasionally flying away in search of food for his mate and nestlings.
