I found a fourth male red-eye near the statue of Columbia; he sang 
steadily for 48 of 60 minutes at 35 to 40 times a minute, but I believe he 
had no mate. At length I reached the bur oak and sat down to watch. Time 
passed and I began to fear the nest had come to grief, for it was 58 minutes 
before there was any sign of the parents. Then mother arrived with an 
insect, fed, looked about, and settled down to brood. During the next hour 
she fed three times, the father not at all; she brooded for nine minutes, a 
half minute, and 13 minutes. He sang for seven or eight minutes in the oak, 
some 10 feet above the nest. 
Again I missed a day, this time through visiting Lincoln park to see 
what birds were nesting there. On the 25th I again made the rounds but 
found nothing but disappointment. The hackberry nest was unchanged. The 
red-eye by the statue was gone. I watched the bur oak nest for two hours 
and concluded that a squirrel must have found it. The only red-eye I heara 
in the whole park was “Eastland” who sang 53 times a minute in the 
Japanese garden. 
The next day even “Eastland” was silent, and my only comfort was in 
the discovery of a baby downy woodpecker in the park, preening himself 
and calling for his father. On July 1, however, I found both “Eastland”’ 
and “Bur Oak” to judge from their rate of singing, 54 and 32 phrases a 
minute, respectively. “Bur Oak” had moved some 250 feet to the south and 
west, but I could see no sign of his mate. During the next two days I noted 
him singing in his territory. 
From July 10 through August we visited the Wooded island 14 times 
— usually near noon or in the afternoon — and we heard red-eyed vireos 
only three times; a bird near the Japanese garden sang 40, 36, and 34 times 
a minute July 25, while on July 31 and August 8 we recorded only inter- 
mittent phrases. On August 20 four well-grown young wood pewees were 
being fed by their parents. By the end of the month when the berries on 
the island were making a brave show — the scarlet of the highbush cran- 
berry, crimson of the haws, dusty pink of the burning bush, and delicate 
rose of the nannyberry — four families of cardinals were still caring for 
large young. But we never found a cowbird baby. 
A great surprise awaited me September 1. As I was struggling to 
identify a troop of migrating warblers, a red-eyed vireo with a tail two- 
thirds grown fiuttered its wings and was fed by its parents! This happened 
some 400 feet to the north of “Bur Oak’s” second territory, but the next 
day the three birds were back home, the baby calling whang and following 
a parent to a dogwood bush whose berries were attracting catbirds, thrash- 
ers, and migrating thrushes. During the next two days I found a red-eye 
eating dogwood berries; on Sept. 6 a few nasal whangs were my last record 
for the season, except for a few migrants in the last third of the month. 
Nearly 10 weeks had elapsed since the robbing of the nest in the bur 
oak and my discovery of the family. I consulted with Mrs. Louise de 
Kiriline Lawrence of Rutherglen, Ontario, who is making a careful study 
of this species. Curiously enough, one of her pairs lost their nest on the 
same day as the “Bur Oaks’; their second nest was robbed July 14.
