Ten ways of seeing

First Look

真山水之川谷,远望之以取其势,近看之以取其质。

—— 宋·郭熙《林泉高致·山水训》

Mountains and valleys: from afar take their momentum, up close take their texture — the two distances from which any picture is read.

The sheet is vertical: the eye climbs and settles on the bird. Take the posture before the plumage. Then step in close: watch where colour meets line, and whether the line ever breaks. Third, find the darkest small patch: the whole tonal order is measured from there.

About this plate

Four species of the genus Ionolæma are now known, two of them having a brilliant metallic spot on the forehead, viz. I. frontalis and I. whitelyana, and two which have no bright spot, I. luminosa and I. schreibersi.

The present bird differs from I. frontalis in having the breast green instead of black: it was discovered by Mr. Henry Whitely at Cosnipata in the province of Cuzco, Peru, in August 1871, at an elevation of 2300 feet above the level of the sea.

Mr. Whitely states that he found the bird very rare, having only met with a male in August, and a female on the 21st of May, 1871. He states that it “frequents flowering plants at the tops of the loftiest trees in the depths of the forest, at nearly all times out of range of gun-shot. Very powerful in flight, and darts from flower to flower with extraordinary rapidity.”

The following description was given by me in the volume of the ‘Annals’ mentioned above:—

Male. Crown, all the upper surface and flanks deep grass-green; an obscure glittering mark on the forehead; chin, chest, and centre of the abdomen jet-black with a broad gorget of beautiful violet on the throat; the bill, which is stout and straight, is black, as are also the legs and toes; the tail and under tailcoverts steel-black; primaries and secondaries purplish brown, the external edge of the outer primary reddish brown. Total length 514 inches, bill 118, wing 3, tail 214.

Mr. Whitely gives the soft parts as follows: “Bill black; eye dark hazel; legs, toes, and claws black.”

The specimens figured in the Plate are the original ones procured by Mr. Whitely, and now in my collection.
