soft grasses and some horsehair. It 

 contained four very finely marked 

 eggs whicli were about Iialf incubated. 



No. 10, Date, May 19, 1912: While 

 myself and Mr. Alex Walker were 

 strolling through a large tract of 

 brushy pasture land, trying to see all 

 we could on the line of bird-life, I 

 struck with my light cane into a clump 

 of bushes saying, "This would be a 

 typical place for a Macgillivray's 

 Warbler's nest," and Mr. Walker, who 

 was new to our western field, took a 

 lietter look into the bushes, and im- 

 mediately called, "there is a nest start- 

 ed here." I took a look at it and could 

 see the crude outline of a nest, which 

 I at once identified as a Macgilli- 

 vray's nest. May 22, I went to see it 

 and found it completed; May 23, it 

 contained one egg; May 26, it held four 

 eggs; May 27 the female sat, when 

 I approached, but when I came within 

 two rods of the nest she disappeared, 

 and on looking into the nest, beheld 

 five eggs of uniform size. The female 

 had laid an egg every day. 



Through the courtesy of Mr. Walk- 

 er I am able to enclose a photo taken 

 from a close range. It was built in 

 the forks of a hazel bush 18 inche?, 

 above the ground, well hidden in the 

 rank fern and weeds. It was composed 

 of weedstems, grasses, some dry fern 

 leaves and barkshreds, lined with fine 

 dry grass and some horse hair. On 

 one side the material extends out to 

 a point of three to four inches from 

 the nest. It was rather loosely put 

 together, however, well cupped; cavi- 

 ty dimensions 2^4 inches in diameter, 

 depth, two inches. During the photo- 

 graphing process neither of the par- 

 ents made their appearance nor any 

 protest.

Please! 

 Send us a lot of short interesting 

 notes, fresh from the field. Those 

 that will occupy from one to ten lines. 

 Every one of you have something of 

 that sort that the rest of us ought to 

 read. 



The Maryland Yellowthroat. 



At Bloomfield, New Jersey and in 

 the nearby towns, this species of 

 Warblers are without doubt the com- 

 monest of the Mniotiltidae which an- 

 nually visit us and remain here dur- 

 ing the summer months with the pen 

 sible exceptions of the Yellow Waro- 

 ler and Redstart. 



No marsh or brookside, however 

 small, in this section can be consider- 

 ed complete without at least one pair 

 of these active and beautiful sylvan 

 masqueraders of the brooksides and 

 lowlands, and usually as you approach 

 a patch of swampy woodlands, es- 

 pecially where the skunks cabbage 

 and catbriers abound, the first out- 

 burst of avian melody which will greet 

 you is the "Witchery, witchery, wit- 

 chery" of the Yellowthroat. 



These birds arrive in the vicinity 

 about May 7th, and in most cases they 

 become a common summer resident, 

 nesting and rearing their families 

 with us each year and remaining after 

 their household duties have been per- 

 formed until the last of September. 

 The 10th of October usually finds them 

 well on their way south and what few 

 that remain after this date are mere 

 stragglers and of rare occurrence.

 cies of Wood Warblers, which I have

 things of unusual interest and below 

 I have outlined a few of the incidents 

 and happenings.
