A Two- Year Nesting Record 445 



young, and the others, three and four eggs respectively. A num- 

 ber of old nests were also found. 



44. Field Sparrow (Spizella p. pusilla). May 9th, 1915. A fe- 

 male was flushed from a nest and four eggs, in a small hawthorn 

 bush six inches from the ground. A rather late date for eggs of 

 this bird is August 14th, when a nest with one fresh egg was 

 found. 7. 



45. Song Sparrow (Melospiza m. melodia), May 30th, 1914. 

 Nest containing 5 eggs and one Cowbird egg was seen in a bed of 

 dead weeds along the Skokie Marsh. Late date: nest and four 

 eggs July 20th, 1915. This and the former are, outside of the Eng- 

 lish, our two most common sparrows. 6. 



46. Swamp Sparrow (Melospiza georgiana), June 11th, 1915. 

 Five eggs. Nest composed entirely of grass and deeply hollowed, 

 situated in dead cat-tails about one foot above the ground. These 

 birds are very plentiful in the Skokie Marsh, and their nests are 

 extremely hard to find. 11. 



47. Towhee (Pipilo e. erytJirophthalmus) , August 9th, 1914. 

 We found this nest while looking for Waxwings. It was two feet 

 up in a clump of hazel bushes, and held three eggs. We have no- 

 ticed that the early nests are placed on the ground, while the later 

 ones are always elevated. 5. 



48. Cardinal (Cardinalis c. cardinalis), June 10th, 1914. Nest 

 In elderberry bush, about six feet up, containing three eggs. About 

 five years ago, a pair of Cardinals appeared in Highland Park, and 

 since then, they have been increasing so that now there are at 

 least five pairs breeding here every year. 



49. Rose-breasted Grosbeak (Zanielodia ludoviciana), May 18th, 

 1914. The only nest of this bird found was in a hawthorn tree 

 ten feet up. It contained three eggs and two Cowbird eggs. These 

 birds are scarce in this locality. 



50. Indigo Bunting (Passerina cyanea) , July 26th, 1915. Nest 

 one foot above the ground in a clump of weeds beside a field of 

 wheat, containing three badly incubated eggs. A scarce bird most 

 years in Lake County. 2. 



51. Scarlet Tanager (Piranga erythromelas) , July 17th, 1914. 

 This bird is about as common as the Rose-breasted Grosbeak. The 

 one nest found was on the end of an oak branch, and held three 

 eggs. 



52. Purple Martin (Progne s. suMs), July 15th, 1915. There 

 were both fresh eggs and young birds, ready to fly, in a house, 

 which we examined today. There are many colonies of these 

 birds about here, and they take very quickly to the houses put 

 up for them.
