MARTYR 203 



humming-birds, flickers, and some other feathered parents, 

 doves feed their fledgliags by pumping partly digested food 

 — "pigeon's milk" — ^from their own crops into theirs. 



When they leave the open woodlands to take a dust 

 bath in the road, or to walk about and collect gravel for 

 their interior grindiag machines, or to get a drink of water 

 before going to sleep, you may have a good look at them. 

 As they walk, they bob their heads in a funny manner of 

 their own. They are bluish, fawn-colored birds about a 

 foot long. The male has some exquisite metallic colors on 

 his neck, otherwise he resembles his best beloved. Beauti- 

 ful birds these, in spite of their quiet Quaker clothes. 



In the Southern states the little ground doves, the small- 

 est of the columbine kin, may be seen by every roadside.
