the Purple Martin and Yellow-throated Vireo. The explanation 

 I should offer for the lateness of the Yellowthroat is that this 

 species is locally distributed and its appearance in some places 

 is only occasional. But you may ask, how does that account 

 for its absence as a migrant when most other species are readily 

 found? I should answer that the species is not abundant any- 

 where near our locality and that the individuals which migrated 

 in our vicinity went directly along their route to their summer 

 homes. 



As to the Purple Martin, I am sure that my date, June i, is 

 not correct for the species, for formerly the first Martins appeared 

 here late in April. No suitable nesting places are any longer 

 available for the birds at Notre Dame, which have all left the 

 locality and now nest in the neighboring city of South Bend. 

 But the dates given for these two species are interesting as showing 

 when they were first seen by a daily observer of bird-life within 

 a restricted territory. 



The writer made his largest record of migrating birds this 

 spring, and had he been more fortunate in his observation of the 

 warbler family, the number would probably have exceeded a 

 hundred migrants.
