 Chestnut-sided Warble.-.-A common species gen- 

 erally, tliat is during a series of years, but often 

 quite rare for a year or so, and again exceedingly 

 common. In 1875 a great many nests were found 

 he first eggs being fallen here in 1874. Since 

 1878 very few nests have been taken. The species 

 arrives from April 25 to May 6. I cannot say 

 how late it remains with us but have found it to 

 bea^rare bird in the Fall. Q,|feO. X.Mar.l885.p.^f 



DendroBca pennsylvanica (Z.) Bd. A small flock arrived 

 May 3, but none were noticed again until May 8, when several 

 others were seen. The number graduallv increased, and May 12 

 it was only exceeded by 6^./o//^a^« rui/c/l/a. May 14 it out- 

 numbered them all ; from this date, however, the flocks gradually 

 decreased, although many remained to breed. The first ep-o- w,« 

 taken June 3. Bnli N.OX3.^,Apll. X883, p. 7C

Dendroica pensylvanica. Chestnut-sided Warbler — An abundant 

 migrant in Beaver County, spring and fall. I have taken and seen imma- 

 ture birds in August (August iS, 1888, and August 24, 1889), which -would 

 seem to indicate that it breeds a little farther north. In Butler and Arm- 

 strong Counties, however, the case is very different ; there, every patch 

 of hazel thicket has its pair of Chestnut-sided Warblers, or, if extensive, 

 its several pairs, the gay and sprightly male ever prominent on its out- 

 skirts or on some shrub in its midst, constantly uttering his short but sweetly 

 modulated song. Notwithstanding this clue, their nests are difficult to 

 find ; after many vain searches I at last succeeded in finding one (June 3, 

 18S9; containing four highly incubated eggs. Auk, 8, Oct. 1891. p. J/K
