tho nests of the Great Blue Herons, several miles back in 

 the cleptiis of the hills. This bird was undoubtedly migrat- 

 ing through this particular situation and probably did not 

 breed there. 



131. Salpinctes obsoletus (Say) — Rock Wren. 



F. J\l. Chapman found the Rock Wren migrating through 

 Halsey in May, 1906. I failed to find any of the birds 

 during my observations, probably because I reached the 

 locality somewhat too late to catch the earlier spring 

 migrants, among which the present species is to be con- 

 sidered. 



132. Troglodytes aedon parkmani A.udubon — Western House 



Wren. 



The Western House Wren migrates through this region 

 during iMay and in August and September, although in rel- 

 atively small numbers. Their bubbling song was a welcome 

 surprise, when I occasional]}^ heard it in the valley thickets, 

 as was also the sight of their little, barred, gray forms 

 whisking through the underbrush or clambering about the 

 shrubbery overhanging the river where they always gave 

 a singularly homelike aspect to the place. The dates which 

 I have for the species are Ausrust 31, 1911, and May 3 7, 

 18, 20 and 21 and September 6, 1912. 



133. Telniafodyfcs pahtstris iUaciis Ridgway — Prairie Marsh 



Wren. 



I saw this marsh wren only on August 28 and 29, 1911, 

 a single bird which was in evidence about a brush heap 

 on a sandbar in the Middle Loup river. The presence of 

 cat-tail swamps and reedy marshes would no doubt favor 

 the presence of this bird in greater abundance than that 

 with which it now occurs here. 



134. Pcnthcstcs atricapilliis scptcntrionalis (Harris) — Long- 



tailed Chickadee. 



From August 22 to September 23, 1911, Long-tailed 

 Chickadees were present sparingly in the Loup valley. 

 R. H. Wolcott recorded their occurrence in July, 1908, and 

 it is possible that the species breeds on the Reserve, al- 

 though no nests have been found. 



135. Regulus calendula (Linnaeus) — Ruby-crowned Kinglet. 



I noted a Ruby-crowned Kinglet on August 22, 1911, in
