BIRDS OF MARSHALL COUNTY

Fig. 



-Nest and eg'gs of the Blue Jay (Cyanocitia cristaia). 



One pair of birds were seen industriously filling a large crack 

 in a maple tree by wedging acorns in it. This particular piece of 

 industry brought them no return as the fox squirrels discovered the 

 store and promptly devoured it. 



100. Corvus brachyrhynchos brachyrhynchos. Crow. Another 

 abundant permanent resident. They nested commonly along the 

 river but their nests were usually so high up as to be inaccessible. 

 The writer frequently saw them carrying sticks in March. On 

 March 22, 1913, three partly completed nests were found. A female 

 was found incubating a set of four eggs on May 10, 1913. On May 

 12 three young were found. This nest was visited May 17, 24 and 

 30 and photographs were taken of the young on each visit. On the 

 30th they had left the nest. On the third visit (May 17) the 

 nestlings were of a dirty color with great blue pin feathers partly 

 covering the body. On May 24 they were completely feathered out 

 and were gone by the 31st. The old birds were never seen or 

 heard during the various visits to this nest after May 10 when one 

 was flushed from the nest.
