Summary: Sialia sialis. — 



This bluebird accepted one insect — Hydrophilus triangularis — 

 which very probably is never taken by wild bluebirds. The ground 

 beetle — Scarites — disregarded and thrice refused by the captive 

 bluebird has been found in collected stomachs of the species. The 

 same is true of the only berry offered it, that of Ilex opaca, which the 

 caged bird rejected. The honey bee, which was refused, and spiders 

 and May-beetles, which were disregarded as well as accepted, are also 

 eaten by wild bluebirds.
