THE OOLOGIST. 



An Unknown Nest. 



Oil the 20tli of May, I was lookiiij); for 

 the nests of Wilson's Thrush in a pieoe 

 of brush near hei'e, when I saw a bird 

 flit away from a bush just ahead, 

 which, from its general resemblanee, I 

 called Wilson's Tlirusli, so did not 

 watch it. 



But, upon going to the nest, I wished 

 I had, for it contained one egg measur- 

 ing liQ X .43, spotted qnite thickl3' with 

 brown on a light blue gronnd. 



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 I)ack four days 

 later, found another egg. colored like 

 the lirst, but spotted, thicker, measur- 

 ing .63 X .47. It had the ai)peai"ance of 

 haviug lain there several daj's, having 

 settled into the bottom of the nest. No 

 liird was seen thi.s. time. 



Now, were they runt eggs of Wil- 

 son's w the 01iv»-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 anybodj" who can 

 give ji'.formation.

The Eggs of Audubon's Warbler. 



'Slv. Samuel B. Ladd.of West Chester, 

 Fa., sends us the following 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 more like the Maryland Yel- 

 low-throated than the Yellow Warbler 

 and some specimens would ..t tirst 

 strike you as more like Orchard Orioles. 

 Mine were all collected in Colorado and 

 I have the nests, which is a great addi- 

 ti(m to their value.'' 



A Cheap Collecting Box. 



In reply to Mr. A. Drouet's (juery in 

 the March Oologist, I would say that 

 [ have e(dlected eggs now for o years 

 and th(^ cheapest and liest collecting 

 box I have found is an 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 which 

 you can fasten a strap or string and 

 put it over the shoulders in the same 

 way as a lish basket. I have found 

 them convenient in climbing for crows" 

 nests and the like, and also they will 

 hang neatly under the coat.

Book Review- 

 Key to North American Birds. Elliot 

 CoULs. Fourtli edition. ISiJO. 



In presenting the fourth edition of 

 this standard work, the only change 

 instituted by the autlun- over the prev- 

 ious edition, is the addition of a Second 

 Appendix. 



It will be rememiiered that the 

 "First Appendix," published with the 

 previous edition, presented in double 

 columns, the diffei'euces between the 

 Key List of 1*884, and the Union List of 

 1886, introducing such changes as the 

 author saw lit to make in that edition 

 of 1887. 



The "Second Api)endi\" notes every 

 further change reported by the Union's 

 Committee from 1837 to January 1890 

 inclusive. 



Upon most .of these changes, the 

 author expresses no individual opinion, 

 presuming the judgment of the Com- 

 mittee to be final. But the names of 

 species and subspecies Avhieh he is full}" 

 prepared to admit to the Kej' as addi- 

 ti(nis or emendations are printcMl in 

 thick type. 



Thus, the Key covers the latest devel- 

 opments in ornithological knowledge 

 and reveals the latest conclusions of 

 science right up to date.
