In the selection of a locality there is a manifest 

 evidence of design. High grounds are seldom 

 chosen for nidification, for the obvious reason that 

 the birds are not so apt to meet with such a ready 

 and full supply of the various insects that pander 

 to their appetites as in the former situations. The 

 inseqts which^ afford them nourishment in such 

 localities are the aquatic larvae and images of 

 ephemerids, libellulas, and mosquitoes, which are 

 denizens of shallow pools. The following insects 

 contribute to its bill of fare during ity stay: — 

 Culex tceniorhynchus, Anopheles quadrimaculatus, 

 Tabanus lineola, Stomoxys calcitrans, Tipula fer- 

 ruginea, larvae of smaller dragon flies,, and cater- 

 pillars of Hybernia tiliaria, Anisopteryx vernatd, 

 Utetheisa bella, Ennomos subsignaria, Argynnis 

 aphrodite, Colias philodice, and mature forms of 

 Spilosoma Virginica, Halesidota tessellaris, Litho- 

 sia miniaia, and many of the Lycesnidce, Noctmd(S, 

 and Tortricidcs ; together with Aphides, Coccidce, 

 ants, and earthworms. These last two, together 

 with small beetles, the birds ~ procure while 

 gleaning upon fallow ground. The seeds of 

 various weeds and grasses, besides the berries of 

 Juniperus Virginiana, Prunus cerasus, P. serotina, 

 Amelan chier canadensis, Fragaria Mrginiana, 

 Rubus villosiis, R. strigosus, and Vaccinitun 

 stamineum, are, also eagerly relished. 



It has been affirmed that the Red Wing is very 

 destructive to farmers' crops, but as far as our 

 experience extends, the damage which it commits
