Bacon, is the only record for this relatively southern species so far 

 north in Pennsylvania, and its seasonable status is quite uncertain. 

 Farther east along the lake shore it has been recorded but once, from 

 near I^uffalo, N. V. (Savage, Auk, XII, 1895, 314). 



219. Troglodytes aedon. House Wren. 



Rather common as a summer resident, not only on the Peninsula, 

 but even in the city itself, where it often nests, while nearly every 

 farmhouse has a pair breeding in its immediate vicinity. On May 30, 

 1900, a nest with six fresh eggs was found, built in the deserted hole 

 of a woodpecker in a stub close to the board-walk, the shrubbery along 

 which was a favorite haunt of the si)ecies at all times during its stay. 

 Its arrival has been observed by Mr. Bacon about the first of May 

 (Al)ril 30, 1893; May 3, 1892), and in 1900 October 3 was the 

 latest fall date. Mr. Sennett writes entertainingly {Auk, VI, 1889, 

 76) of a nest found by himself and Dr. B. H. Warren on August i, 

 1888, which was built in a kingfisher's hole in a sand-bank, and con- 

 tained young birds. 



220. Olbiorchilus hiemalis. Winter Wren. 



Of moderately common occurrence during the spring and fall migra- 

 tions, and occasionally in winter also. Mr. Bacon has seen it on Janu- 

 ary I, February 2 and February 22, 1892. Its first and last recorded 

 occurrences in the spring of 1900 were respectively April 9 and May 

 10. In the fall it was noted only on October 10 and 11. Mr. Sen- 

 nett's collection contained examples taken October 27 and 29, 1888. 



221. Cistothorus stellaris. Short-billed Marsh Wren. 



This comparatively little known species was noted on but one occa- 

 sion, May 17, 1900, when a single female was shot by Mr. Worthing- 

 ton at the head of Yellow Bass Pond, having been flushed from a growth 

 of low weeds and bushes near the water's edge. It is probably to be 

 set down as a rare summer resident. 



222. Telmatodytes palustris. Long-i;illed Marsh Wren. 



In the marshes of the Peninsula this interesting species is an abun- 

 dant summer resident. By the writer it was first met with in June, 

 1899, about Yellow Bass and Niagara Ponds, when a number of speci- 

 mens were collected and several new (but empty) nests discovered. 

 In 1900 it was first observed April 30, becoming common May 9. 

 May 23 several unfinished nests were found, and on May 31 a set of 

 six eggs was collected from a nest in Niagara Pond, a favorite haunt
