Ethiopia and Eritrea have a desirable and certain avifauna. Poorly identified compared to many elements of Africa, wisdom on chicken distribution within the international locations is scattered in the course of the literature. For greater than 35 years, the authors were painstakingly amassing chicken documents within the zone and plotting them on half-degree maps, together with released files, facts from museum specimens, sightings from their very own broad travels and, extra lately, files from the numerous birdwatchers that now stopover at Ethiopia. The ensuing atlas presents, for the 1st time, a correct evaluation of the distribution of every of the 870 species identified from the 2 international locations, together with invaluable info on breeding. The succinct textual content summarises the consequences and discusses distribution to subspecies point. broad introductory chapters hide themes akin to topography, geology, plants, weather, habitats, conservation, migration, breeding seasons, chicken ringing, and the heritage of ornithology within the quarter. This groundbreaking booklet fills a wide gap within the literature for essentially the most different and least recognized parts of Africa.

As a self-proclaimed twitcher—a birdwatching extremist who travels round the state attempting to capture a glimpse of as many species of birds as possible—the writer took a 12 months off in 2002 with the objective of seeing seven hundred birds and thereby breaking the nationwide list for many birds visible in a single 12 months.

The average annual temperature varies from 18 to 20°C. Such dry forests are dominated by Juniperus near Halai, at Cohaito, at Mrara and on Saber Mountain in Eritrea, and at Wofwasha forest near Ankober. For other species associated with this type of forest, see the Appendix. On the eastern side of the escarpment, the forest is of a drier type, presumably because of the rocky soil, unimpeded drainage and higher average temperatures. The present status of these forests is unclear. b. The dry evergreen montane forest of the highland plateau Dry evergreen montane forests associated with Acacia woodlands and grasslands occur in much of the highlands in the northern and north-western, central and south-eastern parts of the region.
Where woodlands become thicker in lusher areas, forming dense evergreen thickets or merging into forest including gallery woodland, Narina Trogon, Gabar Goshawk and Brown Snake Eagle occur. Huge numbers of Palearctic migrants enter and leave Africa through the Acacia–Commiphora woodlands of the central Rift valley and the south-east, relying on the habitats they provide as a rich source of food. 4. Forest habitats By comparison with woodlands, forest canopies tend to be multilayered, more closed and continuous, formed by taller trees, often 20–30m high, with the tallest having their crowns above the main canopy.
