cially distinct on the wing-covertg and secondaries ; hinder neck marked

dark brown, the subterminal bar being somewhat triangular in shape; 
tail brown, similarly barred with ashy and tipped with fulvous; quills 
dark brown, with paler edgings; under surface buffy white, inclining to 
deep fawn on the breast and abdomen, which are longitudinally streaked 
with blackish brown, the flanks, under wing-coverts, and axillars barred 
with the same color. Cere, bill, and feet paler than in the adults. 
“Young female-——Brown, head and cheeks blackish; feathers of upper

ERNEST’S FALCON. 
Falco ernesti SHARPE, Ibis (1894), 545; Hand-List (1899), 1, 273; GRANT, 
Ibis (1895), 438; (1896), 530; McGrecor and WorcesTER, Hand-List 
(1906), 44. 
Falco atriceps CLARKE, Ibis (1895), 476. 
Luzon (Heriot, Whitehead); Negros (Keay, Whitehead); Sibuyan (McGre- 
gor *) ; Siquijor (Celestino). New Guinea; Greater Sunda and Fiji Islands. 
Diagnosis.—Similar to Falco melanogenys but blacker ; beneath every- 
where shaded with ashy gray; wing-lining and axillars black, crossed 
with narrow white bars. Length, 394 mm.; wing, 295; tail, 140; 
tarsus, 48.7 
“The adult male [collected by Hose at 1,400 meters on Mount Dulit, 
Borneo] is a remarkably beautiful specimen, and is evidently of the same 
race of peregrine as Mr. Pretyman’s bird from the Lawas River, but is 
not quite so red on the chest. The closeness of the barring of the under 
wing-coverts and axillars is remarkable and gives the species a much 
blacker look than F'. melanogenys while no specimen of the last name 
falcon in the [British] Museum has the under tail-coverts and thighs 
bluish gray like the sides of the body. Whether Falco ernesti (as I have 
named the bird, after Mr. Ernest Hose) is confined to Borneo I can not 
yet tell, but I think that it is very likely to be found to be the resident 
form of all the Indo-Malayan Islands, as a specimen procured by Mr. 
Maitland-Heriot in Manila seems certainly referable to it.” (Sharpe.) 
Grant says: “In adults of F’. ernesti, though the breast is occasionally 
* The Sibuyan specimen was recorded as Falco peregrinus in Publ. Govt. Labs. 
(1905), 25, 11. 
+ Sharpe’s diagnosis is as follows: “F’. similis F. melanogeni, sed nigricantior, 
subtus ubique cinereo adumbratus, et subalaribus axillaribusque nigris, lineis 
parvulis albis transfasciatis. Long. tot. 15.5 poll., ale 11.6, caude 5.5, tarsi 1.9.”
