1S97, and that was a small one, a few hunilrcd birds in all. The Pec- 

 toral Sandpiper was practically not rcjjresented in the migrations of 

 1900, but the following year it was found in small numbers. The 

 \Vhite-rumi)ed and Stilt Sandpipers, the Knot, Red-breasted Snipe, 

 Hud.sonian Curlew, and Northern Phalarope ought, in my judgment, 

 to occur here regularly, but certain it is that we get very few shore- 

 birds, other than Yellow-legs (both species), Semipalmated Plover, 

 Killdeer, Least and Semipalmated Sandpipers, Sanderlings, and an 

 occasional Black -bellied and Golden Plover. I hope that the decrease 

 ajjparent in water-birds of nearly all kinds merely means that they are 

 migrating by safer routes, but I fear that what I have noted at Erie is 

 but a fair sample of what has been observed throughout the country." 



Two hundred and thirty-seven species of birds have been recorded 

 from the region of which this paper treats — a larger number than have 

 been observed in any other area of similar size in the western part of 

 Penn.sylvania, and the list is still obviously far from complete. More- 

 over, it is evident that further observations would add largely to the 

 notes on the seasonal occurrence and alnmdance of many of the less 

 common species. Considerable difficulty has been encountered in 

 attemjiting to classify the various components of the avifauna according 

 to their seasonal status, as in some cases such is uncertain or indeter- 

 minate, and the lists that follow must be regarded as provisional only, 

 and subject to modification in the future. 



Eighteen species are to be classed as jjermanent residents, two of 

 them doubtfully, as their occurrence throughout the year is inferred 

 rather than known. They are : 



Coliniis i'irgi/iianits, ? Centiinis caroliniis, 



Bonasa umbelliis, Otocoris alpestris praticola, 



Nyctalops zoi/sonianus, Cyanocitta crisfata, 



Syrnium variiim, Astragali iius irisiis, 



Cryptoglaiix acadica, Melospiza cinerca mclodia, 



Otus asio, ? Cardinalis cardinalis, 



Asio mage/la nil us virginianiis, Ampclis cedronoii, 



Dryobat^'s villosiis, Sitta landineiisis, 



Dnohatcs pubescens mediatuis, Pants africapil/i/s. 



Eighty-eight species may be placed in the list of summer residents, 

 and doubtless some listed as transients belong here also, as the locality 

 is well within their known breeding range. On the other hand there
