Cherrie on Costa Rican Birds. [October 



fall of 1889 Aug. 25, on which date a number were seen. Those 

 taken were very fat. From this date they were common, and by Sept. 17 

 abundant, then the numbers seem to have diminished, until during 

 October, November, December and January they were only tolerably 

 common. During the latter part of January and the first of February 

 they were the most common Warbler in the vicinity of San Jose. From 

 this time they were common until the first of May. None of those taken 

 last showed any signs of breeding. 



65. Dendroica coronata. — They were not noted in the fall, and only 

 twice in the spring: a female in good plumage was taken Jan. 19, and a 

 male and a female were seen Feb. 15. 



66. Dendroica pensylvanica. — In the spring of 18S9 the last individual 

 seen was a male, April 24. The first arrival noted in the fall was one of 

 (lie unfortunates of the night of Sept. 28, also a male. By Oct. 13 they 

 were abundant, but this was their last appearance. There is one skin in 

 the museum collection labelled "San Jose, Nov. 18S7." None were noted 

 in the spring of 1S90. 



67. Dendroica blackburniae. — The first Blackburnian Warbler was 

 noted Sept. S. They were not seen again until the 24th, and then again 

 not until the 29th, when a specimen was picked up in the street, a victim 

 of the panic of the night before. They were common from that time 

 until Oct. 13, when I recorded them as abundant, but within three or four 

 days all had disappeared and none were met with again until their last 

 appearance Feb. 9, 1890, when several were seen. 



68. Dendroica virens. — The museum possesses a single skin labelled, 

 "San Jose\ Nov., 1887. A 1 faro." 



69. Seiurus aurocapillus. — I have only once noted the Ovenbird at 

 San Josd, on Oct 27, 18S9. 



70. Seiurus noveboracensis. — Last year (1889) I had frequent notes 

 until May 21, when I took a female, the last seen. This spring my last 

 note is April 20. In the fall of 18S9, I saw the first Sept. 14. A number 

 were victims in the disaster of the night of Sept. 28. They are never 

 common. 



71. Seiurus motacilla. — I have one in my collection, taken in San 

 Jose\ March 9, 1S90. 



72 Geothlypis formosa. — There is a skin in the museum, without 

 date. 



73. Geothlypis Philadelphia. — Rare in this vicinity. The last seen in 

 the spring of 18S9 was on April 24; the last in 1S90, April 27. The first 

 to return last year was noted Sept. 1. Quite a number perished on the 

 night of Sept. 28, 1889; with one exception they were all females. 



74. Geothlypis macgillivrayi. — A very good example of Macgillivray's 

 Warbler was one of the victims of Sept. 28. 



75. Geothlypis trichas. — Very rarely seen at San Jose. This year I 

 took a female in good plumage April 29. The last seen in 1S89 was a 

 female, March 29. I' have no records for the fall and there are no fall 

 specimens in the museum collection.
