DELAWARE VALLEY ORNITHOLOGICAL CLUB. 11 



"This year, 1902, I have noted far more than in any previous 

 year, finding it from Green Village (Morris Co.) to Rahway 

 and west to Mt. Horeb (2d mountain north of Bound Brook), 

 and generally distributed in the intervening country. I have 

 covered more ground than ever before, this year, which may 

 partly account for the greater numbers noted, but it has unques- 

 tionably been much commoner this year. I never before met 

 it in June south of the mountains. 



"Following is a Ust of all the Henslow's Sjiarrows noted this 

 year, and doubtless nearly all were breeding: 



April 20. — 1 Washington Valley, Washingtonville; 1 Passaic 

 Valley, Berkely Heights. 



April 27.— 1 Iselin (Middlesex Co.). 



May 11. — 2 Coontown (mountains). 



May 18. — 2 Mountains. 



May 24. — 2 Mountains. 



June 7.^1 Berkely Heights. 



June 14. — 1 Washington Valley. 



June 15. — 1 north of New Dover. 



June 18. — 1 west of Scotch Plains. 



June 22.— 1 Menlo Park (Middlesex Co.). 



July 5. — 2: 1 Great Swamji, Myersville ; 1 Passaic Valley, 

 Gillette. 



July 6. — 2 Ash Swamp. 



July 12. — 2 west of Scotch Plains (same as June 18). 



July 14. — 1 or more Great Swamp. 



July 17. — 5 Great Swamp. 



July 20. — 4 south of New Dover. 



"While up to 1902 I had found so few south of the mountains, 

 I had found it much more commonly in the Passaic Valle}', and 

 especially the Great Swamp. I believe that they breed in the 

 Great Swamp region every year. They seem to be very erratic 

 in their choice of a summer home, in this respect resembling 

 the Short-billed Marsh Wren, which is often found in the same 

 places. I have found them in some wet meadow one year, and 

 the following year not one would be there, though the Swamp 

 Sparrows and other common birds were present as usual, and 

 the haunt apparently unchanged.
