The Tufted Titmouse is a common resident. 

 735a. Pentliestcs atricaplUus septcntrionalis — Long-tailed Chickadee. 

 735a. Penthestcs atricapillus sextentrionalis — Long-tailed Chickadee. 



These two species are not distinguishable in the field. The 

 chickadees are one of our most numerous winter birds. In 1917 

 careful records showed a gradual thinning out, beginning about 

 March 25, but they were still common May 6. After the 6th of 

 May the numbers were less. After May 15 they were seldom 

 seen except in deep woods. In fall of 1916 they became more 

 numerous and began to move out of deep woods into more open 

 places about September 1, but they were not common until about 

 September 20. Thereafter observed almost daily. 



Family SYLVIIDAE — Kinglets, Gnatcatchers. 



748. Regulus satrapa satrapa — Golden-crowned Kinglet. 



While this species is a winter resident, he is not common. 

 The first museum recoi'd is November 14. The field record for 

 1917 shows one specimen for March 17 



749. Regulus calendula calendula — Ruby-crowned Kinglet. 

 Kansas is within the winter range of this common migrant. 



In the spring of 1917 the first arrivals were observed on March 25. 

 From that date the kinglets were quite common till April 22. 

 They came, as it seemed, in a body and left in like manner. The 

 museum records April 27. Observed abundantly in 1916, October 

 12, according to same record. For Lane County, September 27, 28 

 to October 21. 

 751. Pilioptila caerulca caerulea — Blue-gray Gnatcatcher. 



This species is rare as a summer resident, but as a migrant 

 quite common. The time of migration is irregular. The museum 

 records show specimens taken on April 17; one on April 9; and 

 one on the 13th and one on the 22d of May. They return in Au- 

 gust and leave the same month. The fall records show two speci- 

 mens captured on August 27 and two on August 29. 



Family TURBIDAB — Thrushes, Robins aad Bluebirds. 



754. Myadestes townsendii — Townsend's Solitaire. 



The Townsend Solitaire is an occasional fall and winter vis- 

 itant. No data. 



755. Hylocichla miistelina — Wood Thrush. 



This species is common during the summer. It arrived in a body 

 on May 1, 1917. In the fall the numbers gradually decrease. The 

 fall records show it as last seen on September 27. Its quiet, se- 

 cluded habits during fall makes necessary more careful searching. 

 756a. Hylocichla ftiscescens salicicola — Willow Thrush.
