Noted regularly in the thick woods along the inlet and outlet 

 of Lake McDonald. It was still in song. As at Sin-yale-a-min, 

 we were unable to secure a specimen without destroying or 

 losing it in the hurrying water. This diminutive hermit of the 

 arbor vitae forest is wonderfully expert in dodging observa- 

 tion, whisking in and out of the observer's view with provoking 

 restlessness, and generally perching upon branches extending 

 over the water. 



726 b. EOCKY MOUNTAIN CEEEPEE, CertUa familiaris 

 montana Eidgw. 



The Eocky Mountain creeper was not uncommon in the 

 woods near our various camps. It occasionally visited the ad- 

 jacent trees, and was generally noted in our daily lists. Spec- 

 imens were frequently taken on the grounds of the Biological 

 Station. 



727 a. SLENDEE-BILLED NUTHATCH, 8iUa carolinensis 

 aculeata (Cass.) 



Common in the vicinity of the lakes and water-courses. Like 

 the creeper, it frequently manifested its presence near our 

 camp by its weak, penny-trumpet call. 



728. EED-BEEASTED NUTHATCH, Sitta canadensis Linn. 



Quite common in the woods near the Station. On the fii-st 

 day of our return to the Station, a specimen of this nuthatch 

 was taken on the Club grounds. We also noted its occurrence 

 at Estey's Pond, and in all suitable localities included in our 

 August collecting. 



735 a. LONG-TAILED CHICKADEE, Parus atricapillm 

 septentrionalis (Harris.) 



Common throughout the Flathead region. 



738. MOUNTAIN CHICT^ADEE, Farus gambeli Eidgw. 



This handsome chickadee is doubtless a common resident of 

 the mountainous regions in the vicinity of Flathead Lake, but
