DELAWARE VALLEY ORNITHOLOGICAL CLUB. 7 



{Spizella pusilla^ in this vicinity in winter, associated with flocks of 

 Tree Sparrows (6". monticola^ and suggested that they might v/inter 

 here in greater numbers than had been supposed and have been hitherto 

 overlooked. 



March ly, i8gi. — Nine members present. 



Mr. Thos. H. Montgomery, Jr., was elected an Associate Member. 



The office of Secretary-Treasurer was divided, and Mr. Wm. L. 

 Baily was elected Treasurer. 



Mr. Stone reported that the weekly migration schedules showed that 

 68 species of birds were under observation during February. The 

 great bulk of migration during the month took place on the i8th, 23d, 

 24th and 25 th. These were warm days following spells of rainy weather, 

 and it was evident that the foremost groups of migrating birds having 

 been checked in their journey by spells of cold and rainy weather, em- 

 braced the first opportunity offered by a bright warm day for continu- 

 ing their migration, and having been increased by arrivals from farther 

 south, caused a more concentrated movement on these days. In 1890, 

 the first of these bird-waves occurred at Philadelphia on Feb. 14th, 

 26th and 27th. 



Mr. Reed read a paper on the " Hawks of Pennsylvania and New 

 Jersey," which was discussed by the other members. Black Hawks 

 (^Archibiiteo lagopus sancti-johannis') still occur in winter in considerable 

 numbers on the Delaware marshes near the Lazaretto, but are seldom 

 seen elsewhere in this vicinity. 



Mr. S. N. Rhoads exhibited an Ipswich Sparrow {Anitnod7-amiis 

 prmceps) which he had found dead at Atlantic City, N. J., after the 

 blizzard of March, t888. 



Mt. Morris recorded the capture of a Swallow-tailed Kite {Elanoides 

 forjicaius) at Olney, Phila., shot by Mr. Edw. Van Artsdalen in the 

 spring of 18S8. 



April 7, i8gi. — Nine members present. 



Mr. Morris exhibited a curious female Maryland Yellow-throat ( Geo- 

 thlypis trichas), which had an unusually large bill. The specimen was 

 shot at Olney, Philadelphia, September 19, 1883. 



Mr. Stone displayed a curious Orchard Oriole {^Icterus spunus) from 

 the Academy collection, which had one side colored like the adult male 

 while the other side was olive green like a bird of the first year [See 

 Bull. Nutt. Orn. Club, 1882, p. 181.] Mr. F. M. Chapman, of the 

 American Museum of Natural History, New York City, has suggested 

 that this specimen was probably an hermaphrodite, as had proved to be 

 the case with a similarly colored Fringilla coelebs recorded in the Ibis.
