"Young male. Above brownish, the feathers edged with fulvous, espe- 

 cially distinct on the wing-coverts 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

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. t 



"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 Kiver, 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. 



t 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., alee 11.6, caudae 5.5, tarsi 1.9."
