AMYDRUS TRISTRAML, Setater

Tristram’s Amydrus.

Amydrus tristramit, Sclater in Ann. and Mag. of Nat. Hist., 3rd ser. vol. ii, p. 465.—Tristram, Birds of Southern
Palestine, in “ Ibis,” vol. i. p. 32.

 

Tue discovery by the Rev. Mr. Tristram of this truly African form in Asia Minor is a point of consider-
able interest to ornithologists ; so much so, in fact, that I hasten to give a figure of the Amydrus Tristrami
in the ‘ Birds of Asia,” taken from specimens collected by that gentleman, which he has kindly placed in
my hands for the purpose. ‘The following notes from his pen greatly enhance the interest of the subject.
“This handsome bird,” says the Rev. H. B. Tristram, “which Mr. Sclater has done me the honour to
name after me, I discovered in the Gorge of the Kedron, not far from the Dead Sea. Several pairs were
breeding in the rocks among the-cells hewn out by the old monks of Mar Saba. In habits and manners
they reminded me somewhat of the Grakles of North America, but seem a strictly desert bird. The species

ought to be found at Petra, if anywhere. The male has but two notes, but those are of wonderful power
and of the richest volume, The roll of his music is something like that of the Organ-bird of Australia, and
makes the rocks resound. The nest is placed in inaccessible crevices of the cliffs, and the birds are bold
and fearless, allowing a stranger to approach very near while continuing their song, then suddenly breaking

off for an instant and renewing it the moment one stands still. The plumage of the female is much inferior

in brilliancy to that of the male ; but she has the same rich chestnut wings.”

Some doubt having arisen in my mind as to the specific value of this bird, the Palestine specimens were
submitted to the inspection of Dr. Hartlaub of Bremen, who has paid so much attention to the birds of

«There cannot be the slightest doubt as to Anydrus Tristrami being a good species. It is nearly allied
to the 4. fulvipennis, Swains. (the Nabourop of Levaillant), of South and South-western Africa. The size of

both species is the same. The differences are the following :—
“1. The beak of 4. Tristrami is much longer and more robust than that of 4. filvipennis ; it is also more
arcuate. The colour of the beak is corneous in the A. Tristrami, and decidedly paler than that of 4. fulvi-

co

penms, which in my specimen is nearly black.
“2. The tarsi are considerably longer in fiulvipennis than in Tristrami. The only essential difference in

the colouring of the two species occurs on the wing-feathers.

| fi

“ The apical part of these remiges is in both species blackish, and the extension of this blackish colour is in
both equally or subequally extended. If you want to know anything more about the genus Amydrus and
its species, | must refer you to my ‘ Monograph of the Lamprotornthine’ mm the last part of Cabanis’s
‘ Journal fiir Ornithologie,’ lately published.

‘IT cannot say if there be any difference in the colouring of the females of the two species, there being
only males of 4. fulvipennis in our Collection.”

The male has the head, upper and under surface glossy purple, duller on the vent ; wings and tail dull
black, margined with glossy green; primaries cinnamon, largely tipped with blackish brown ; bill and feet
black.

The female has the head, neck, and throat dark ashy grey striated with black ; the remainder of the
plumage as in the male, but much paler.

The Plate represents both sexes of the natural size.
