102. Dendroica vigors! (Audubon). Pine Warbler. — Rare tran- 

 sient; Aug. 27 to Sept. 7. Average date of departure (for two years) 

 Sept. 5. This is a warbler which seems to have escaped my notice during 

 the spring migration, in fact it was not until last fall that I came across it 

 at all and then only two specimens were seen; and three more during the 

 same period of the present year, 1915, although more persistent searching 

 may prove it to be more plentiful than would appear from the above 

 records. The great migration route is through the Penobscot Valley in 

 Maine, some 160 miles or more to the east of Hatley, but even there com- 

 paratively few remain to breed. It is a busy little searcher after food, 

 creeping in and out amongst the leaves, and at migration times can be 

 found almost anywhere in the woods, and not necessarily in pine groves, 

 at least that is my experience. 



103. Dendroica palmarum hsrpochrysea (Ridgway). Yellow 

 Palm Warbler. — Rare transient; May 4. The above date in 1912, is 

 the only one on which I have had an opportunity of observing this warbler, 

 and then only one example was seen, but so near was I to the bird that there 

 was no chance of confusing it with the Palm Warbler, as the reddish Ijrown 

 or rufous breast streaks were plainly visible. 



104. Seiurus aurocapillus (Linnajus) . Ovenbird. — Fairly common 

 summer visitant ; May 1 1 to Sept. 10. Average date of arrival (for two 

 years) May 14; of departure (for two years) Sept. 10. Eggs: June 23 to 

 July 7. Although most of the woods contain a pair or more of these birds, 

 I have only been able to locate three nests so far, two in June, one of which 

 contained a set of 4 eggs, the other being destroyed after one egg had been 

 laid, and the third in July containing 3 eggs, no doubt a second set. 

 All three were on the ground at the foot of little bramble or other shoots 

 and ferns, and were arched over. They were composed of moss, leaves, 

 and grasses, lined inside with skeletonized leaves, fine grasses, rootlets and 

 a few long horse hairs, the average dimensions of two being; outside length 

 5, inside 2f inches; outside depth 4f, inside 3 inches; height 5^ inches; 

 entrance hole 2j X 2 inches. 



105. Geothlypis trichas trichas (Linnaeus). Maryland Yellow- 

 throat. — Common summer visitant; May 12 to Sept. 9. Average date 

 of arrival (for four years) May 20; of departure (for three years) Sept. 7. 

 Eggs: June 8 to July 19. Although this is a somewhat plentiful little 

 warbler, its nest is by no means very easy to find, being well hidden away 

 amongst the grass at the foot of some small bush, or in the midst of a tuft 

 of long grass, surrounded with water. Of the five found so far three con- 

 tained sets of three, and two sets of four eggs each. All were somewhat 

 bulky being composed of dry leaves and coarse grasses with sometimes a 

 little bark, the inside being lined with finer grasses and perhaps a few horse 

 hairs, the average dimensions being, outside diameter 31, inside If inches; 

 outside depth 3?, inside 1^ inches. Sets of this species vary a good deal 

 in shape, size, and markings, one I have being very oblong with one egg 

 marked at the small instead of the large end.
