147. Sitta carolincnsis (Lath.) W)hite-breasted Nuthatch. Abundant 

 resident. Breeds in late /\pril, and early May. 



148. Sitta canadensis (Linn.) Red-breasted Nuthatch. — A fairly 

 abundant migrant, occasionally seen in winter. Appears usually in early Sep- 

 tember, sometimes during the latter part of August, remaining until Novem- 

 ber. Becomes abundant again in early March-May 10. 



149. Bacolophiis bicolor (Linn.) Tufted Titmouse. — Common migrant 

 in spring, not so abundant in fall. Is most numerous in February, March, 

 and April, remaining well into May. A number remain throughout the win- 

 ter. Does not breed to my knowledge. 



150. Parus atricapillus (Linn.) Chickadee. Common resident, breeds. 



151. Rcgulus satrapa (Licht.) Golden-crowned Kinglet. — An abundant 

 migrant in early spring and fall, an irregular winter resident. Arrives from 

 the north in late September, remaining until November 1st. In spring, March 

 and April are the months of its greatest abundance. Seldom remains later 

 than May 3rd. 



152. Rcgulus calendula (Linn.) Ruby-crowned Kinglet. — A common 

 migrant, more abundant some years than in others. Arrives in late April, 

 remaining until around May 10th. Returns in early September, finally depart- 

 ing in October. 



153. Polioptila cacrulca (Linn.) Blue-gray Gnatcatcher. — Common sum- 

 mer resident in some sections, in others not often observed. Arrives about 

 April 28th, remaining until September 10th. 



154. Hylocichla mustclina (Gmel.) Wood Thrush. — Common summer 

 resident. Arrives between the 23rd arrd 28th of April, common by May 1st. 

 The bulk have left by October 1st, but I have observed several as late as 

 October 19th, in 1902. 



155. Hylocichla fuscescens (Steph.) Wilson's Thrush. — An abundant 

 summer resident. My extreme dates in spring of this bird's appearance are 

 April 22 (1900) -May 4 (1902). Departs during the latter part of September, 

 fatest record October 10th, in 1893. 



156. Hylocichla aliciac (Baird) Gray-checked Tlirush. — A not uncom- 

 mon migrant. Arrives April 27th-May 21st, again in September. Careful 



notes on this bird here afe much to be desired, as it is confused with the 

 olive-backed thru.sh. More extended work during the migrations will doubt- 

 less find aliciae more common. First taken here in 1898 by J. Claire Wood. 



157. Hylocichla szvainsonii (Cab ) Olive-bicked Thrush. — A fairly com- 

 mon migrant April 30th to May 15th. Again in September. 



158. Hylocichla guttata pallasii (Cab.) Hermit Thrush. — Common mi- 

 grant. Arrives as a rule about the 18th of April; in 1S89 the first was ob- 

 served April 3rd. Lingers until May 1st. In autumn appears in the latter 

 part of September, a few remaining occasionally into November. 



159. Morula migratoria (Linn.) American Robin. — An abundant summer 

 resident, a few remain throughout the winter. Arrives February 26-March 24, 

 departs October 27-November 9. 



160. Sialia sialis (Linn.) Bluebird. — Common summer resident. The
