54 NATURE-STUDY REVIEW !15:2— Feb., 1919 



of 126 students, 55 men and 71 women, he found that each man 

 knew on the average from 31-35 different birds, but that each 

 woman knew only i i-i 5 different species. 



After a few periods of field work, it became apparent that it was 

 not yielding as good results as was expected. Therefore the field 

 work was reorganized around some few of our most common birds, 

 with the aim of giving easy recognition by sight and note, facts 

 concerning their habitat and economic importance and some plans 

 for encouraging and protecting them rather than seeking to glance 

 at a great number of different birds. The method was now tried, 

 of having the students study each bird according to some definite 

 scheme and recording in writing all observations made. This 

 scheme was a modification of that used by Dr. R. M. Strong, in his 

 bird courses while at the University of Chicago. The modified 

 scheme follows: 



DIRECTIONS FOR FIELD WORK WITH BIRDS 



1. Size: 



Compare with the English sparrow, robin or crow. If possible, 

 estimate length. 



2 . Form : 



Note whether the bird is slender or compact, the shape of bill, 

 and any unusual features such as length of legs, neck, etc. 



3 . Color : 



Note distinctive colors and color effect from a distance. 



4. Flight: 



Describe the flight as well .as possible. If necessary, represent 

 diagrammatically. 



5. Voice: 



Try and represent the song by syllables or any other way that 

 will indicate what the song sounds like. Distinguish between call 

 notes and songs. 



6. Where found: 



(a) On ground 



(b) In low trees, bushes or thickets 



(c) In high trees 



7. Nest: 



(a) Where placed 



(b) Height above ground 



(c) In what 



(d) Size
