An Interesting Occurrence of the Canyon Wren.— On the 23rd of November, 1906, 

 I took a Canyon Wren, Catherpes mexica7ius conspersus, near Cheyenne Wells, Colorado. This 

 is a prairie country about seventeen miles west of the Kansas line and hardly the place where one 

 would expect to find this bird. The exact locality was near Smoky Creek, six miles north of the 

 town. There is a small outcrop there of coarse sandstone and conglomerate, and it was about 

 this that I found the bird. The weather was very cold and raw. Mr. C. E. Aiken considers it an 

 unusual thing for the species to be so far out on the plains and thinks it must have been migrat- 

 ing. I know of no record for the bird so far east in Colorado. — Edward R. Warren, Colorado 

 Springs, Colorado. 



A Bit Too Previous. — Spring fever, as it is commonly called, when a fellow just feels like 

 breaking the traces and getting far away from the strenuous wear and tear of civilization, I be- 

 lieve comes with the first hint of spring to every nature lover who is closed up in an office. 



It comes in many different forms. Sometimes it is a smell, sometimes a picture, or a look 

 into the pages of an old field book. Or perhaps a day's trip thru the foothills will bring reminis- 

 cences of the freedom and serenity of getting far into the mountains away from the city's strife. 



But here is an instance when spring came, as it seemed to me at the time, in midwinter. 

 The 22nd of February being a holiday, I was looking over some bird skins in our log cabin at 

 San Anselmo, when the familiar squeaky notes of a Hummer brought me to the door to see what 

 might be doing. Everything was still, and seeing some Juncos close by, I imagined I heard them 

 and not the Hummer, their notes being at times very much the same — especially when the Hum- 

 mer is poised in the air at some flower uttering those sharp short notes. However I leaned 

 against the door and waited. Back came the little green Anna with her mate. They dropped 

 to the ground under a laurel, the male spreading out his gorgeous neck feathers and making 

 quite a love scene with Anna. Finally like a shot he went his way, and she lost herself ten feet 

 above the spot in the laurel. I walked over to the tree and after a diligent search discovered her 

 sitting on a frail little nest about half built. She soon became restless at my gaze and left the 

 nest, but soon came back with a large piece of cotton, tucking it under her breast with her bill 

 and pulling it vigorously with her feet into place. Noting how roughly she bustled around in 

 the nest, I was somewhat astonished when later in the day I peered into it and saw a set of eggs, 

 one dark in incubation, and, as it proved, this must have been laid about the i2tli of February. 



I have never come across anything just like this in the nesting habits of birds, but the Hum- 

 mers being early nesters and on account of the rains, I judge in this instance it was a case of sit 

 close to save the nest and contents. Hence the one egg incubated and the other perfectly fresh. 



Being the earliest date at which I have ever found a Hummer nesting, I feel safe in saying 

 that San Anselmo has a record for early Hummers' nests, and at the same time the discovery has 

 relieved me of the indescribable craving for spring. — H. H. Sheldon, San Francisco, California.
