Like other members of this group the two species above described lead a very retired life among the sheltering branches of their favourite trees, from whence their most strange and very monotonous song is to be heard almost incessantly throughout the day.
The HOODED SHRIKES are easily distinguishable from the last-mentioned group by their comparatively long, graduated tails, short wings, in which the fourth quill exceeds the rest in length, and remarkably long tarsi.
It is at present uncertain if all the species of Shrikes inhabiting Western and Eastern Africa can be included in this group. The coloration of their plumage is almost identical, and in their habits they closely resemble each other, but considerable variety is observable in their size. All make their homes amidst such thick brushwood as grows close to the ground, and they never seek the shelter of the trees except when very closely pursued. If driven from their favourite lurking-places amongst the bushes and long grass, they fly with rapid strokes of the wing to the nearest shelter, keeping close to the earth as they hurry along, but occasionally hovering for a few moments before concealing themselves. Whilst in search of insects, they run upon the ground with a rapidity and ease far exceeding the powers of any other members of their family.
Except the facts that these birds associate in small parties during the period of incubation, and live alone or in pairs at other seasons, we are without particulars as to their nidification and breeding, and have been unable personally to observe their habits.
THE TSCHAGRA.
The TSCHAGRA (Telephonus erythropterus)—the species we have selected for description—is brownish grey upon the upper part of the body, and light grey beneath. A broad black line passes over the head, and another, somewhat narrower, crosses the region of the eye. These lines are separated by a light streak, which is white upon the face, but becomes of a yellow tinge towards the sides. The outer web of the quills is grey, but is so broadly bordered with reddish brown that when the wings are closed they appear to be almost entirely of the latter hue. The upper secondaries are edged with reddish grey; the two centre tail-feathers are grey, marked with dark stripes; the rest are black, tipped with white, those of the exterior have also a light border to the outer web. The eye is reddish brown, the beak black, and the feet lead-colour, with a greenish shade. In length the Tschagra does not exceed eight inches, its breadth is ten inches, the wing measures three inches and the tail three and a half. It is, at present, uncertain whether the very similar birds inhabiting Eastern and Western Africa are identical with this species. In colour they are closely alike, but differ somewhat in size.
