THE OOLOGIST 



Catbird- — I have found four sets of 

 five eggs of the Catbird and have ex- 

 amined six hundred and forty-five 

 nests to find them. They were col- 

 lected May 28, 1907, at Torresdale, 

 Philadelphia County, Pa., incubation 

 slight; June 1, 1913, at Bustleton, this 

 county, Pa., incubation one-third; May 

 20, 1906, at Pensauken, Camden Coun- 

 ty, X. J., incubation fresh; and May 

 19, 1906, at Holmesburg, Philadelphia 

 County, Pa., incubation slight. 



Wood Thrush — 1 have examined four 

 hundred and thirty nests of this spe- 

 cies in the vain quest of a set of five 



Cogs. 



Yellow-breasted Chat — But tw« 

 nests containing five eggs or young o: 

 this moonlight songster has come un- 

 der my observation in the one hundred 

 and twenty-seven nests I have exam- 

 ined. The first of these was found on 

 July 16, 1907, at Frankford, Philadel- 

 phia County, Pa., and held five naked 

 young (no Cowbirds) and was certain- 

 ly a large brood for a second setting; 

 the other nest contained five eggs, one 

 infertile and four containing large em- 

 bryos and was found at Chestnut Hill, 

 Philadeli)hia County, Pa, 



Field Sparrow — Of the one hundred 

 and sixty-four nests of the species 

 which 1 have examined but three held 

 over four eggs or young. They are as 

 follows: (1) May 20, 1909, Delair, 

 Camden County, X. J., five eggs, one 

 infertile and >four almost hatched; 

 (2) June 3, 1912, Bustleton, Philadel- 

 phia County, Pa., four half-grown 

 young and one infertile egg; (3) May 

 25, 1913, Walnut Hill, Montgomery 

 County, Pa., five hatching eggs. 



Indigo Bunting — I have found but 

 one set of five eggs in the one hundred 

 and twenty-nine nests of this species 

 I have examined and this set was 

 found on June 8, 1906, at Rowland- 

 ville, Philadelphia County, Pa., and in- 

 cubation was highly advanced, pip- 



ped in two and the eggs were extra 

 large ones too. 



Robin— c-f Oologist 1912, page 330 

 for my data on large sets of this spe- 

 cies. 



Phoebe — The only nest of this spe- 

 cies holding more than five eggs I 

 found on April 30, 1901, at Holmes- 

 burg, Philadelphia County, Pa., in a 

 spring house; it consisted of six fresh 

 eggs and was one of the sixty nests 

 that I have examined in hopes of find- 

 ing over five eggs. 



Cardinal — The books assert that this 

 species commonly lays three and four 

 eggs, but out of an examination of 

 two hundred and ten nests I have 

 found only three holding over three 

 eggs. As follows: (1) May 6, 1906, 

 Pensauken, Camden County, X. J., four 

 pipped eggs; (2) April 30, 1908, Torres- 

 dale, Philadelphia County, Pa., four 

 fresh eggs; (3) June 2, 1912, Bustleton, 

 Philadeluphia County, Pa., four fresh 

 eggs and a second set, the "first con- 

 sisted of three fresh eggs. 



Song Sparrow — Some books state 

 that this species lays from four to 

 seven eggs, but five is the highest 

 number of eggs or young I have ever 

 seen in the four hundred and thirty 

 nests I have examined. 



Swamp Sparrow — Out of the Five 

 hundred and sixteen nests of this spe- 

 cies to come under my notice only 

 one held over five eggs or young. This 

 was found on June 1, 1905, at Brides- 

 burg, Philadelphia County, Pa., and 

 consisted of six eggs, two sets of two 

 and four respectively; the couple was 

 Iresh and incubation in the four was 

 two one-half and two infertile. They 

 were laid by two females as the set 

 of two were much smaller than the 

 other clutch and different in markings. 



We regard the foregoing as one of 

 the very best of the oological articles 

 of the year appearing anywhere, bar 

 none. — Editor.
