Geothlypis formosa. Kentucky Warbler (271, 296, 297). Breeds regularly. This 
bird is not uncommon in Allegheny and Beaver counties. 
Sylvania canadensis. Canadian Warbler (271, 301). Saw a pair of these beautiful 
warblers near Corn planter run in Armstrong county, last June (1890), and, judging 
from their actions, I felt convinced they had nest in the vicinity. 
Thryothorus bewickii. Bewick’s Wren (309, 310). Rare visitor.' 
Parus bicolor. Tufted Titmouse (318). Common resident in Allegheny and 
Armstrong counties.

Tardus f uscescens. Wilson’s Thrush (325). Common summer resident in Butler 
county, and along Cornplanter run on western borderof Armstrong county. “Nearly 
every extensively-wooded stream in Butler county is made vocal by the ineffable 
song of Wilson’s Thrush from about the 20th of May until the last of July. 1 have 
found ten pairs breeding along the course of a small stream. What music, there in 
the evening, about sundown ! I have never been able to leave the spot until the last 
note reverberated through the still woods. Antiphonal, for they seem to answer one 
another continually. The Veery is a ventriloquist. I have caught him practicing 
this art while observing him through a field glass.” 
Tardus ustulatus swainsonii. Olive-backed Thrush (326). Regular spring and 
fall migrant. 
Tardus aonalaschkce pallasii. Hermit Thrush (326, 327). Regular spring and fall

me in 1889 and 1890, four were on the ground. 
Galeoscoples carolinensis. Catbird (305). Witnessed the robbery of an English 
sparrow’s nest last summer (1890) by a Catbird. The sparrows defended their 
treasure with great courage, but their enemy persisted until the eggs were taken.
