474 General Notes. [§^J^ 



nesting habits in Plymouth Township, mentioning the male as frequently 

 uttering its love notes while wheeling high in the air, and describing the 

 solicitude of the adults for their young. The writer recently wrote him 

 for more accurate data and his reply under date of July 17, 1908, is in 

 part as follows: "I first discovered the Bartramian Sandpiper in the 

 spring of 1873 — a single pair — and whether they bred or not that year 

 I cannot say. I did not see them again for some years but for the past 

 fifteen years they have been a constant breeder at this place. I have two 

 sets of eggs collected here; one set of three taken May 5, 1899, and one set 

 of four taken May 10, 1899. The first set was fresh and the second slightly 

 incubated. They were in the same field within ten rods of each other. 

 Another set was found here but I did not get the particulars. The birds 

 have been with us here all this spring, but are at present hiding in the tall 

 grass and hay fields. Would like to have you see their jjeculiar actions 

 while nesting and hear them whistle while in mid air." 



Pine Siskin, Spinus pinus. — In the same note Mr. Taverner also 

 conveys an erroneous impression of the local status of the Pine Siskin. 

 The writer has observed more than a hundred during the last eighteen 

 years, mainly in the northeastern portion of the county. The bird is less 

 abundant and even more erratic than the Redpoll. — J. Claire Wood, 

 Detroit, Michigan. 



Krider's Hawk and the English Sparrow Nesting Together. — During a 

 recent trip to the Dismal River in the Sand Hill region of northwestern 

 Nebraska, I found, some fifteen or sixteen miles away from any habitation, 

 a nest of Krider's Hawk from which I took on May 25 two well incubated 

 eggs. One was beautifully colored while the other was immaculate. In 

 the lower part of the nest, which was constructed of coarse sticks, a pair of 

 English Sparrows were nesting. I did not take either of the hawks, 

 believing it a crime to destroy such a beautiful bird that is now so rare. 

 The male was rarely seen, but the female might easily have been shot 

 when flushed from the nest. She was exceedingly wild and elusive and 

 when flushed did not return to the nest for a considerable time, and, then 

 by a round-about course, and with great caution. I had the pair under 

 observation for two days before taking the eggs. — John Lewis Childs, 

 Floral Park, N. Y. 



Migration of Hawks. — In Mr. Justus von Lengerke's note on ' Migration 

 of Hawks' (Auk, XXV, pp. 315-316), the line of migration is described as 

 toward the Delaware Water Gap and, as my observations covered that 

 portion, I would like to report what I saw in 1904 while living in Shawnee, 

 four miles up the river. 



The line of flight for hawks, and also other birds, such as Crows, Black- 

 birds, Nighthawks, etc., was down the west side of the river just below 

 the crest of the hills until reaching a point about two miles above the Gap, 

 when they would invariably rise over a low corner of the hills and pass on
