6 BowDiSH AND Philipp, Tennessee Warbler. [j"n_ 



present year, would, according to our experience, seem little more 

 than casual. 



The stomachs of four birds taken were preserved and sent to 

 Mr. H. W. Henshaw, Chief of the Biological Survey, United States 

 Department of Agriculture, who kindly furnished the following 

 copies of analyses of contents : 



No. 1, male, June 21, contents; eight small caterpillars (as in 

 No. 3), 35%; Dipterous fragments, 23%; a small spider, 2%; 

 scale-like fragments (perhaps of some catkin), 40%. 



No. 2, female, June 22; empty. 



No. 3, female, June 23, contents: a camponotid ant, 16%; 

 at least 78 small caterpillars (Tortricidse), 75%; a snail (Vitrea 

 hammoides) 4%; unidentified vegetable fragments, 5%. 



No. 4, male, June 28, contents: 3 Lampyrids near Podabrus, 8%; 

 a small Coleopterous (?) larva, 3%; about 15 small caterpillars (as 

 in No. 3), 25%; a Neuropterous insect (apparently a caddis fly), 

 50%; 2 small spiders, 14%; trace of unidentified vegetable matter. 



In connection with the subject of food, a note published in the 

 'Bulletin of the Nuttall Ornithological Club,' Vol. V, 1880, 

 page 48, by J. A. Allen, cites destruction of grapes by these birds 

 in Kansas in September of the previous year, the birds puncturing 

 the skin and eating the pulp or succulent parts. 



On the other hand, W. F. McAtee, describing his experience with 

 injury to grapes by these birds, in 'The Auk,' Vol. XXI, 1904, 

 page 489, found that while puncturing many grapes, the Warblers 

 did not eat the pulp, but seemed to quench their thirst with the 

 juice. Examination of stomach contents showed insects of species 

 most injurious to grapevines, and as the Warblers are present in 

 the grape growing areas as transients only, it is argued that such 

 harm as is wrought by the grape puncturing habit is probably far 

 more than offset by the insects eaten. The suggestion is also 

 made that by supplying abundance of water, the injurious habit 

 might be eliminated. 



Little information seems available as to the migration of the 

 Tennessee Warbler in New Brunswick. The Biological Survey 

 has but two records of arrival, both for Petit Codiac, by John 

 Brittain; May 19, 1886, and May 26, 1888. 



In conclusion, it may be of interest to cite the more pertinent
