4. Nycticorax nycticorax naevius. Black-crowned Night Heron. 



This species has been observed but rarely during the breeding 

 season, though there seerus to be no reason whv it should not be 

 plentiful. 



5. Philohela minor. American Woodcock. 



Rather common, but yearly becoming scarcer as a breeder. 



6. Bartramia longicauda. Bartramian Sandpiper. 



One bird observed in an upland pasture near Dimock, June 

 19, 1897, and evidently breeding from its actions, is my only record 

 for the county. 



7. Actitis macularia. Spotted Sandpiper. 



Common in all suitable localities. 



8. Colinus virginianus. Bob-white. 



Much less common now than formerly, but solitary individuals 

 and an occasional covey are still frequently met with. During the 

 last two years, however, there has been a noticeable increase in the 

 numbers of this bird throughout the county. 



9. Bonasa umbellus. Ruffed Grouse. 



More plentiful than C. virginianus, but fast becoming rarer as 

 the forests are cut away, thus depriving it of suitable breeding 

 grounds and hiding places. 



[10. Ectopistes migratorius. Passenger Pigeon. 



A flock of four was seen July 19, 1897, in a dead chestnut tree 

 on the edge of a strip of woodland near Dimock. Although I had 

 a good look at the birds through my glass and feel no reasonable 

 doubt as to the identity, I was unfortunately unable to secure any 

 of them. This species is known to have formerly been an abundant 

 breeder in Susquehanna County, but these are the first individuals 

 seen for many years. This occurrence at this season of the year 

 may possibly indicate that they still nest occasionally in the wilder 

 parts of the county]. 



11. Zenaidura macroura. Mourning Dove. 



This species, which may be regarded as common to the Alleghe- 

 nian and Carolinian zones, though perhaps more typical of the lat- 

 ter, is not uncommon in some localities, although decidedly rare in 

 others.
