The lower part of the crop of the mother of the young bird was hypertrophied, 

 and exuded the secretion known as " pigeon's milk." 



Iris of males, yellow. 



Mr. Millspaugh reports that the craw of the mother bird contained " 200 

 seeds representing four unknown species of the euphorbiaceous genus Croton." 

 With regard to the two males taken on April 3d, he says ; " One of the craws 

 contained two large and fully ripe fruits of some cultivated species of Day lily 

 (Crinum). These fruits must have been about 1^ inches in diameter, and 

 were completely filled with a multitude of ripe, bony seeds. There were also 

 found under this number : 46 seeds Tragia ?iepetaefolia ; 8 seeds Croton species ; 

 2 minute seeds of some scrophulariaceous plant ; 43 seeds Croton fiavens ; 14

 species."
