which had excavated cavities and appeared to be preparing to breed, 

 were driven off by the English Sparrows. Mr. Scott observed the first 

 arrivals, two birds on September 7, 1899, and after that date the birds 

 soon became abundant. 



217 (731)- Tufted Titmouse. Parus bicolor Zz/zw. 



A common resident species throughout the year, especially so dur- 

 ing fall and winter, when they travel in bands and feed on the pin oak 

 acorns. These birds are so seclusive and retiring during the breeding 

 season that but few nests have been found. Mr. Robert H. Southard 

 found one early in May 1897, and Mr. C. R. Babson found a pair breed- 

 ing in a large pin oak May 16, 1901. 



218 (735). Chickadee. Parus atricapillus Zm«. 



A regular and not uncommon winter resident. None remain during 

 the summer. 



219 (736). Carolina Chickadee. Parus carolinensis 

 Arid. 



a not uncommon resident, very retiring during the breeding season. 

 The only nesting record is May 29, 1901, when Mr. Edward W. 

 Scudder found a nest containing six fresh eggs. 



Family Sylviidae. Kinglets and Gnatcatchers. 



220 (748). Golden-crowned Kinglet. Regulus sat- 

 rapa Licht. 



A common winter resident. The Golden-crowned Kinglet arrives 

 from the north the first week in October and at once becomes abundant 

 in all cedar groves and clumps of pines. By April 25 the last strag- 

 glers have left here for their northern breeding grounds. 



221 (749). Ruby-crowned Kinglet. Regulus calen- 

 dula {Linn.y 



Found in all evergreens, this species is a very common migrant, 

 passing through on its southward migration during the latter part of 

 September and October and returning during April and May, when the 

 males are in full song.
