the next; again, some appear, remain 

 a few days and tlien pass nortliward. 

 A few are permanent residents and 

 are indeed welcome, for as far as I 

 liave observed and according to tlie 

 best autliorities no maledictions are 

 cast at them for bad habits. On the 

 contrary they are rather pitied by 

 some naturalists because of the fact 

 that they are so imposed upon by -the 

 detestable Cowbird (Molothrus ater.) 



Their plumage is, on the whole, bril- 

 liant and no sight is ever so pleasing 

 to me as several warblers hunting for 

 food. 



The most abundant Warbler I have 

 observed is the Myrtle Warbler; next 

 comes the Northern Water Thrush; 

 then the Maryland Yellowthroat, Yel- 

 low-breasted Chat, Louisiana Water 

 Thrush, Magnolia Warbler, Black-and- 

 White Warbler, Wilson's Warbler, 

 Chestnut-sided Warbler, and Yellow 

 Warbler. 



The Myrtle Warbler arrives about 

 April 25th and is common by the next 

 two days. It remains here until May 

 15 and then passes northward. On its 

 return migration it passes through 

 Jonesburg from October 20 until the 

 26th. 



Both the Northern Water Thrush 

 and the Louisiana Water Thrush ap- 

 pear about the last day of April and 

 are common by May 2. They are all 

 gone northward by May 10th. 



The Maryland Yellowthroat arrives 

 April 25-27, is common by 26-28 and 

 remains here during the spring and 

 summer. I do not recollect seeing 

 them after August 1st and have no 

 notes of their presence after that date. 



The Yellow-breasted Chat arrives 

 May 1-5, is common by May 7-15 and 

 remains here during the remainder of 

 May and the month of June. I have 

 never observed it after July 1st. 



Of the other Warblers named I have 

 scarcely observed their movements 



long enough to state with sufficient ac- 

 curacy any dates relative to their mi- 

 grations.

Pine Warbler (Dendroica vigorsi) at 



Bloomfield, N. J., During 



December, 1915. 



On the morning of December 19, 

 1915, in Watsessing Park, near Bloom- 

 field Center, a male Pine Warbler was 

 observed by the writer. The bird was 

 in company with several Juncos and 

 Golden-crowned Kinglets and seen 

 among the shrubbery and on the 

 ground feeding. The ground was cov- 

 ered with about ten inches of snow 

 and it was bitter cold at the time with 

 the thermometer registering ten de- 

 grees above zero. Under the shrub- 

 bery were several patches of bare 

 ground and it was on one of these 

 patches this unusual visitor was feed- 

 ing. 



On the morning of the 21st and 22d 

 it was again seen at this point and 

 then disappeared. 



The latest record I have of this 

 species was made in 1912 at Haskell, 

 New Jersey, on November 2d, and the 

 earliest record was made on April 6, 

 1906. Louis S. Kohler. 



The Prothonotary Warbler. 



The Thompson Lake region on the 

 Illinois River is probably the central 

 breeding place of this beautiful warb- 

 ler. The nearby lakes of Mud Grass 

 and Flagg are also much frequented. 

 Mud Lake is about a half mile long 

 and an average width of two hundred 

 yards and yet around this small body 

 of water probably twenty-five pairs 

 were breeding this year. 



The writer for about forty years has 

 made a journey at least once a year to 

 some one of these bodies of water to 

 collect a few of these birds and their
