On the Birds of Ritchie County. 139 



was the only specimen noted. It closely resembled the preceding species 

 in all its motions, occasionally launching out after an insect, and was 

 silent and very shy. The uniformity of its coloring, together with its 

 large size, served, however, to identify it at a glance. 



Family HIRUNDINIDiE. The Swallows. 



39. Hirundo horreorum Barton. Abundant everywhere in the clear- 

 ings. 



40. Tarhijcineta bicolor (V.) Cs. Rare. A single specimen observed 

 April 29th, by Mr. Ingersoll, in a flock of Progne 'purpurea around a mar- 

 tin box. 



41. Petrochelidon lunifrons (Say.) Cab. Abundant, arriving May 3rd. 

 Nested under the low eaves of a log hut in the village. 



42. Stelgidopteryx serripmnis (Aud.) Bd. Arrived May 1st, and sev- 

 eral colonies of six or eight individuals each were soon established in the 

 rocky fi cuts" along the line of the railroad. Here they were evidently 

 preparing to build, as each pair had already selected some little projec- 

 tion of the rocky cliff, where they would sit together for many minutes at 

 a time. Another small company also haunted the vicinage of a bridge 

 over the creek, and had probably selected the stone abutments for a nest- 

 ing place, as they frequently passed in and out underneath. 



This bird is readily distinguishable on wing from C. riparia, by its 

 greater size and slower flight; indeed, in this latter attribute it much 

 more closely resembles T. bicolor, like it sailing much of the time, and 

 proceeding in a very leisurely manner; its note is, however, more nearly 

 that of the former species, but rather louder and harsher. Like the 

 other members of the family they were very fond of lighting along the 

 telegraph wires to rest and plume themselves. 



43. Progne purpurea (L.) Boie. Common, breeding in the martin 

 boxes put up for their occupancy. No instances of the aboriginal habit 

 of nesting in hollow trees came under our observation. 



Family AMPELIDiE. 



44 Ampelis cedrorum (V.) Bd. Not common. A few specimens 

 were noted by Mr. Ingersoll in September, 1873. 



Family VTREONID^. Vireos, or Greenlets. 



45. Vireo olivaceus (L.) V. Rather common in the woods. Arrived 

 May 1st. 



4fi. Vireo gilvus (V.) Bp. Not very common and apparently re- 

 stricted to the belt of willows, etc., along the creek. Arrived May 1st. 



47. Vireo flavifrons V. Decidedly the most abundant of the family 

 here, being found everywhere throughout the woods.
