THE OOLOGIST. 



An Unknown Nest, 



On the 20tb of May, I was looking t'(.)r 

 tlie nests of Wilson's Thnish in a piece 

 of bi'ush near here, Avhen I saAV a bird 

 flit away from a bush just ahead, 

 Avhich, from its general resemblance, I 

 called Wilson's Thrush, so did not 

 watch it. 



But, upon going to the nest, I wished 

 I had, for it contained one egg measur- 

 ing .56 X .43, spotted quite thickly with 

 brown on a light blue ground. 



The nest was placed about a foot 

 from the ground between four upright, 

 twigs and resembled the usual nest of 

 Wilson's Thrush, but was smaller. I 

 left the nest and going back four days 

 later, found another egg. colored like 

 the first, but spotted, thicker, measur- 

 ing .63 X .47. It had the appearance of 

 having lain there several days, having 

 settled into the bottom of the nest. No 

 bird was seen this time. 



NoAv, Avere they runt eggs of Wil- 

 son's or the Olive-backed Thrush, and, 

 if Wilson's, is there any record of spot- 

 ted eggs of Wilson's Thrush being 

 taken; would be glad to hear, through 

 the OoLOGiST, from anybody Avho can 

 give information.

The Eggs of Audubon's Warbler. 



Mr. Samuel B. Ladd,of West Chester, 

 Fa., sends us the folloAving description 

 of the eggs of Audubon's Warbler from 

 a series of sets in his extensive collec- 

 tion : 



"The eggs of Audubon's Warbler are 

 of a bluish-white background, with 

 markings inore like the Maryland Yel- 

 low-throated than the Yellow Warbler 

 and some specimens would :A. first 

 strike you as more like Orchard Orioles. 

 Mine were all collected in Colorado and 

 I have the nests, Avhich is a great addi- 

 tion to their value." 



A Cheap Collecting Box. 



In reply to Mr. A. Di'ouct's query in 

 the IMarch OoLOGiST, I would say that 

 [ have collected eggs noAV for 5 j^ears 

 and the cheapest and best collecting 

 box I have found is aii old plaster box. 

 Take and make two holes one each side 

 of the seam and put a piece of wire 

 through in the form of a ring, to Vvhich 

 you can fasten a strap or string and 

 put it over the shcnilders in the same 

 way as a fish basket. I have foimd 

 them conA-enient in climbing for croAvs' 

 nests and the like, and also they Avill 

 hang neatly under the coat.

Book Review. 



Key to North American Birds. Elliot 



CoUES. Fourth edition. 1890. 



In presenting the fourth edition of 

 this standard Avtu'k, the only change 

 instituted by the author over the prev- 

 ioxis edition, is the addition of a Second 

 Appendix. 



It Avill be rememljered that the 

 "First Appendix," published Avith the 

 previous edition, presented in double 

 columns, the differences between the 

 Key List of 1884, and the Union List of 

 1886, introducing such changes as the 

 author saw lit to make in that edition 

 of 1887. 



The "Second Appendix" notes every 

 further change reported by the Union's 

 Committee from 1887 to January 1890 

 inclusive. 



Upon niost of these changes, the 

 author expresses no indiA'idual opinion, 

 presuming the judgment of the Com- 

 mittee to be final. But the names of 

 species and subspecies Avhich he is fully 

 prepared to admit to the Key as addi- 

 tions or emendations are printed in 

 thick type. 



Thus, the Key coA'ers the latest devel- 

 opments in ornithological knoAvledge 

 and reveals the latest conclusions of 

 science right up to date.
