weed problem. Furthermore, birds confine their feeding chiefly 

 to uncultivated ground and neglected corners of the farm. Mr. 

 Rhoads was glad that there were weeds to furnish food for our 

 winter birds. 



Ajiril 16, 1908. Nineteen members present. Dr. Trotter 

 addressed the Club on " Brain and Organs in Birds" illustra- 

 ting his remarks with diagrams. 



Mr. Stone exhibited several specimens of parrots appar- 

 rently referred to different genera on account of slight differences 

 in bill contour and called attention to the striking similarity of 

 coloration. He considered that color-pattern was in such cases 

 an older character than bill contour and that by giving slight 

 structural difference so much weight as generic characters, we 

 often misrepresented the phylogeny of a group. 



Mr. Morris described a canoe trip down the Egg Harbor 

 River, March 25-26. He noted great numbers of Red-breasted 

 Nuthatches {Sitta canadensis) and one Pileated Woodpecker 

 {Phld'otomiis pileatus abieticola). 



May 7, 1908. Tweny-two members present. Mr. Harlow 

 described the nesting of the Duck Hawk {Falco peregrinus ana- 

 turn) on the Nockamixon Cliffs on the Delaware river in Bucks 

 Co., Pa., and his successful efforts to secure a set of eggs. The 

 latter were deposited upon a bare shelf of rock with no vestige 

 of a nest. Mr. Harlow was of the opinion that this species 

 nested also on the Tammany Cliff, at the Delaware Water Gap, 

 and Mr. Rhoads stated that he had seen the birds about the 

 Gap on three different occasions. Mr. Harrower described 

 several trips to Clementon, N. J. He saw a Hooded Warbler 

 there on May 23 and a Redstart on June 9. Mr. Rhoads re- 

 ported House Wrens as absent from Haddonfield this spring. 

 This was the last meeting held in the old Ornithological room 

 of the Academy, which is to be partially destroyed in the pro- 

 jected alterations to the building. 



May 21, 1908. Thirty-two members present. Mr. Baily de- 

 scribed a June trip to Mt. Pocono, Pa., illustrating his remarks 

 with a series of beautiful lantern slides. He found nests of the
