"On June 4th, 1889, I took a nest of formosa on a 

 shady, steep hillside, at the foot of a small sassafras {S. 

 officinale). The set contained four eggs; incubation 

 sHght. 



"My latest record of G. formosa is September the 12th ; 

 my observations lead me to believe that it does not tarry 

 long after this date." (Original notes).

188. GEOTHLYPIS TRICHAS IGNOTA (Chapman). 

 Florida Yellow-throat. 



The first mention of this species is the record of a male 

 taken June 17, 1876, at Greensboro, whose "stomach con- 

 tained debris of insects." The follovs^ing was appended: 

 "This little bird seems to abound in the thickets about 

 marshes and streams. Its song is so similar to that of 

 the house wren (Troglodytes aedon, the singing trog- 

 lodyte) that it requires a practised ear to distinguish be- 

 tween them." Another bit of evidence that the Doctor 

 was young at the work in '76. 



A couple of early records are Feb. 15, 1887, when the 

 Doctor heard the notes of a yellow-throat, and Mar. 20th, 

 when an adult male was seen. A female was taken on 

 Mar. 11, 1890. 



May 24, 1888, a set of three eggs was collected near 

 Greensboro. "Incubation of three or four days. Nest 

 was concealed on a blackberry vine, and supported about 

 three or four inches from the ground, in thick briers and 

 weeds." 



In April, 1891, the Doctor writes in his journal : "Nest 

 of Geothlypis trichas was found on the 23rd ; it contained 

 only one egg ; an egg was laid every day till the set (four) 

 was produced. Nest on the ground near a bunch of 

 broom grass (Andropogon virginica)."
