AVIFAUNA COLUMBIANA. 



none had ever been seen before. We observed several in the Smith- 

 sonian Grounds for a few days, with the Orioles and Tanagers. [289] 



Fig. 44. — Rose-t>reasted Grosbeak. 



103. (136.) Guiraca ccerulea (Linn.) Sw. Blue Grosbeak. 



A summer resident, rather rare ; arrives first week in May ; departs 

 about the middle of September. There used to be a bush clump on 



Boundary street, near the terminus of Twelfth, where a pair nested for 

 several seasons — we think likely the very birds that Mr. John Bur- 

 roughs speaks of in one of his charming books. Again, we used to find 

 it breeding in one of the fields just west of the Old Soldiers' Home. It 

 nests in much the same bush-clumps that a Cardinal might select, but 

 at other times is found in more exposed situations, as orchards, open 

 woods, the shade of roadsides, &c. [291]
