When the young do come the female is usually more active in feeding them than the male. Among the birds of prey, like hawks and eagles, the female is the larger and more powerful, and therefore better able to defend and to care for her young. Among all animals, the affection of the mother for her offspring seems to be greater than that of her mate, though among the birds the male sometimes shows a superabundance of paternal regard that takes in the young of other species. Thus a correspondent sends me this curious incident of a male bluebird and some young vireos. A pair of bluebirds were rearing their second brood in a box on the porch of my correspondent, and a pair of vireos had a nest with young in some lilac bushes but a few feet away. The writer had observed the male bluebird perch in the lilacs near the young vireos, and, he feared, with murderous intent. On such occasions the mother vireo would move among the upper branches much agitated. If she grew demonstrative the bluebird would drive her away. One afternoon the observer pulled away the leaves so as to have a full view of the vireo's nest from the seat where he sat not ten feet away. Presently he saw the male bluebird come to the nest with a worm in its beak, and, as the young vireos stretched up their gaping mouths, he dropped the worm into one of them. Then he reached over and waited upon one of the young birds as its own mother would have done. A few moments after he came to his own brood, with a worm or insect, and then the next trip he visited the nest of the neighbor again, greatly to the displeasure of the vireo, who scolded him sharply as she watched his movements from a near branch. My correspondent says: "I watched them for several days; sometimes the bluebird would visit his own nest several times before lending a hand to the vireos. Sometimes he resented the vireos' plaintive fault-finding and drove them away. I never saw the female bluebird near the vireos' nest." That the male bird should be broader in his sympathies and affections will not, to most men at least, seem strange.
