Young — Flight of Shore Birds 193 



cr, the undesirable party may withdraw, and operate the cam- 

 era by means of a thread, watching the birds through a field 

 glass, and taking the picture at the psychological moment. 

 Why not let the cyclopic eye of the camera verify the obser- 

 vations on the amount of food given the young? I admit 

 that I have not tried this out, but I find in looking over my 

 negatives that I have quite a number of photographs showing 

 the parent with a definite amount of food in the bill, and I 

 think that possibly very definite results might be obtained af- 

 ter a little experience, if the object were kept in mind. To 

 illustrate my point I ofifer the photographs accompanying 

 this note. Whether these will show as clearly in print as 

 they do on lantern slides is very doubtful indeed, but the 

 slides, when projected on a screen, show the food in great 

 detail, so that it may be roughly identified.

 was on July 27th, when we found Pectoral, Least, Semipal- 

 mated and Solitary Sandpipers, Wilson's Snipe, Great Blue 

 Heron and Black Tern. On August 3, in addition to the 

 above, we found the Semipalmated Plover, Yellow-legs, and 

 Dowitcher. 



On August 10 and 11 there were many shore-birds of the 

 common kinds, and in addition we saw 4 Western Willets, 4 

 Dowitchers, one Western Sandpiper, one White-rumped 

 Sandpiper, one Greater Yellow-legs, 2 Red-backed Sand- 

 pipers, also the Common Tern. On these days there were
