V ?s 9 f] General Notes. 335 



This was in the first two weeks of August, 1893. In Dr. Jonathan 

 Dwight, Jr.'s, interesting paper on 'Summer Birds of the Bras d 'Or 

 Region of Cape Breton' (Auk, Vol. IV, p. 13) this species is included in 

 the list, but nothing is said as to its abundance. Dr. Dwight's observa- 

 tions were made in the first half of August, 18S6. Now my own experi- 

 ence was very different, for in the nine days from June 4 to 12, 1S90, 

 spent in Baddeck and vicinity, including excursions to St. Anne's Bay 

 and Northeast Margaree, I found, as stated in 'The Auk' (Vol. VIII, p. 

 164), not a single Red-eyed Vireo. 



Dr. Arthur P. Chadbourne spent the summer of 1SS7 * n Waterville, 

 N. H., and I was there during the last two weeks of June, this year. Dr. 

 Chadbourne has kindly given me a copy of his field list, and on com- 

 paring it with mine, I find quite a number of differences. Perhaps the 

 most remarkable are these. In 18S7 Dr. Chadbourne found about half a 

 dozen Colaptes auratus there. This year I found none, and so familiar 

 and noisy a bird could hardly have escaped my notice, had it been 

 present. On the other hand I found Ammodramus sandwichensis savanna 

 tolerably common, Clivicola riparia (one sizable colony), and several 

 Tardus fnscescens, which I heard singing whenever I walked down the 

 road about sunset; but apparently none of these three species were 

 present in 18S7. Moreover, Dr. Chadbourne did not observe Dendroica 

 mactilosa there until after the middle of July, and those that he then 

 found he took to be migrants, while seven years later I find them 

 common birds in the Waterville Valley and, as it seemed to me, the 

 commonest of the Warblers there. Vireo olivaceus was represented in 

 18S7 by only a single pair while in 1S94 they were actually abundant. 

 The woods were full of them. Dr. Chadbourne found Dendroica coro- 

 nata common on mountain summits, but did not see them on the slopes 

 or in the valley until July 30, whereas I found them in the latter part of 

 June quite common all through this region, though commonest at the 

 higher elevations. Zonotrichia albicollis also was apparently present in 

 much greater force this year than in 1887. 



The causes of these irregularities are probably many and various, but 

 the facts themselves struck me as interesting and perhaps too readily 

 lost sight of in making generalizations. — Francis H. Allen, West
