ART. 10 BIRDS OF PINCHOT EXPEDITION FISHER AND WETMORE 19 



MNIOTILTA VARIA (Linnaeus) 



Black and white warbler 



Motacilla varia Linnaeus, Syst. Nat., ed. 12, vol. 1, 1766, p. 333. (Santo 

 Domingo.) 



Not uncommon among the undergrowth on Swan Island April 19, 

 1929. 



DENDROICA PETECHIA FLAVIDA Cory 



St. Andrews golden warbler 



Dendroica fiavida Coey, Auk, May 28, 18S7, p. 179. (St. Andrews Island, 

 Caribbean Sea.) 



A young bird in full juvenal plumage taken on St. Andrews Island 

 April 27, 1929, is the first of this race to come to the National 

 Museum. This bird is somewhat worn, but as yet shows no indica- 

 tion of the molt into first fall plumage. The upper surface is deep 

 mouse-gray to mouse-gray, with a wash of ecru-olive on the forehead 

 and light yellowish-olive on the rump; wing coverts deep mouse- 

 gray edged lightly with olive-buff; primaries and secondaries black- 

 ish, bordered lightly with light yellowish-olive; rectrices blackish, 

 edged extensively with olive-yellow on the outer webs, and lightly 

 with reed-yellow on the inner webs; below dull white, with a faint 

 wash of olive-buff on breast; under tail coverts olive-buff; sides 

 smoke-gray; inner webs of primaries edged with reed-yellow and of 

 secondaries with whitish. 



The specimen is much grayer than birds of other races of petechia 

 seen in a similar stage. 



In addition to the bird just described, an adult male golden warbler 

 was collected on Old Providence April 23, 1929, that seems to be 

 the first to be recorded from that island. Through the courtesy of 

 the Field Museum there have been available for examination the 

 type and other specimens on which the race fiavida of St. Andrews 

 was founded, with the result that the Old Providence bird is faintly 

 paler yellow and has the crown yellow instead of rufescent. In heavy 

 rufescent markings below it even exceeds the average of fiavida, a 

 race peculiar for the extent of this color on the under surface. 

 Though these differences appear distinct, yet they are of such a 

 nature as to be possibly within the range of individual variation, so 

 that the Old Providence bird is identified for the present as fiamda. 

 This skin measures as follows: Wing, 63.8; tail, 54.5; culmen from 

 base, 13.2 ; tarsus, 20.3 mm. Further material should be obtained and 

 may easily demonstrate that the Old Providence bird is distinct. 



Adult warblers were seen on St. Andrews but no attempt was 

 made to collect them.
