. American ornithology for the home and school . d keeps the poor tired little mother on the move tosupply it with food. So for every cowbird a whole nestful of insecteating birds are sacrificed. But of course nature planned the Cowbirdfor some purpose and we are learning that its food consists of injuriousspiders and insects, and seeds of obnoxious weeds. These little Yel-low-throats after much scolding decided to outwit the Cowbird, so verysoon they were very busy building a platform over the large Q^z, andin a short time had a very imposing two story mansion. They workedvery steadily indeed, until it was finished, and then flew off for a shortouting before beginning the real cares of housekeeping. No soonerwere they gone than back came Mrs. Cowbird and laid another o.^^ inthe top story. When the owners returned and found that all their laborbad been fruitless they were furious and left the nest never to return.I do not know where they made their next home, but trust that theymay have reared their family in peace. rest h. metcalf.. i68 AMERICAN ORNITHOLOGY.
