several ; and at Stansstad, where it still had its spring note on the 

 28th June. 



P. ater, Continental Coal Titmouse. — At Interlaken an old 

 bird with a very blue-grey back was feeding young branchers at 

 the east end of the town. 1 found a nest on the Engstlen Alp in 

 a crevice in the face of a perpendicular rock shaded by a couple 

 of pines at the top of a steep grass slope. By standing on tiptoe 

 I could just get my finger into the crack, and drawing myself up 

 by my hands, could look in. The young birds were partly fledged, 

 and chirped merrily. I was unable to get hold of the one addled 

 egg which lay in front of them. It looked exactly like an average 

 English Coal Tit's egg. The old birds were so excited that I 

 could watch them within a yard of my head. This form is a very 

 clean looking bird, and the blue-grey of the back is conspicuous. 

 This form is in the Bern Museum, labelled " Bern." 



P.palustris, Marsh Titmouse. — A bird at Interlaken was very 

 "clean-cut" and neat-looking, and was perhaps tne form described 

 as P. palustris, for though I think I have seen it stated that Prof. 

 Fatio says this form does not come into the valleys, there is a 

 specimen in the Bern Museum labelled " Lucerne." Several in 

 the pines just below the Magis-alp (about 4500 to 5000 ft.) were 

 certainly P. borealis, grey-looking with large black cap. This 

 form was also observed in the woods near the Briinig Pass. 



P. cceruleus, Blue Titmouse. — Observed at Bern and at Thun, 

 where it was feeding young branchers. 



Acredula caudata, Long-tailed Titmouse. — We did not see any, 

 and I only mention it in order to call attention to the fact that both 

 this form and A. rosea are in the Bern Museum labelled "Bern." 



Par us crtstatus, Crested Titmouse. — Several in pine woods 

 below the Magis-alp. It has a very grey appearance, and looks, 

 I think, lighter coloured than the Blue Tit. The erected crest 

 was conspicuous in one which sat on a pine top, calling and 

 excited. It would be more heard than seen in the thick pine 

 woods, with boles hoary with long, shaggy lichen. The note is 

 "seet, sect, Beet"; but it has also a sibilant, twittering note. 

 I heard the note in the Briinig woods also. 



Sitta casia, Nuthatch. — Seen at Thun; in the Briinig woods 

 twice, and in the pear orchards in the valley near Stanz. There 

 i» a pretty variety in the Bern Museum, all white except the 

 secondaries and coverts, which are grey. 



Troglodytes par cuius, Wren.— The Wren is a bird of rocky
