Stelgidopteryx serripennis (Aud.). Rough-winged Swallow. 



This species is without doubt our rarest swallow. It is a 

 regular summer visitor, which frequents the same localities as 

 the bank swallow. On several occasions we observed it to en- 

 ter holes in banks, not far from one occupied by a kingfisher, 

 but nothing certain could be found out as to whether it had been 

 breeding or not. The time was early in June, when it should 

 be ready to breed, and a pair was noticed in the same locality 

 for a few consecutive weeks. Unlike the preceding species, this 

 is not at all social, and it is never seen in large communities. It 

 may be observed from April 19th until the middle of September. 

 There is nothing peculiar in its notes. 



PiroMga erythromelas (Viell.). Scarlet Tanager. 



This elegant bird arrives here usually about the beginning of 

 May. It is generally distributed over the country in woodlands, 

 and frequents preferably the tops of trees with thick foliage. 

 The usual notes are some kind of a chirp, besides which it has a 

 few whistling notes, not very loud, but quite pleasant to the 

 listener. Nevertheless, as the bird is of a quiet disposition, it 

 does not make much use of its capabilities as a singer. 



Although a regular inhabitant of our woods, it does not seem 

 to be abundant anywhere. It is of a solitary disposition, and 

 notable for its neglect to seek the company of others, even of its 

 own kind. Towards the end of August it prepares to leave this 

 region, and so regular is its migrating that we have thus far 

 failed to find even a single individual as late as the 1st of Sep- 

 tember. 



Piranga rubra (Linn.). Summer Tanager. 



This Tanager, better known under the name of " Summer 

 Redbird," is much rarer than the " scarlet tanager," as well dur- 

 ing the period of migration as throughout the summer. It ar- 

 rives here about the second week in May, or a little later than 

 the "scarlet tanager." Early in September it leaves us, and
