Ostrich: Journal of African Ornithology is the leading ornithological journal in Africa, and publishes peer-reviewed scientific papers and short communications (<2,000 words) on all aspects of ornithology conducted in Africa and its associated islands and marine habitats. Contributions reporting on avian behaviour, breeding, conservation, demography, ecology, migration, morphology and systematics are welcome. Review articles are particularly encouraged. Extended taxonomic papers may be considered for publication particularly if they include relevant discussion of behavioural, ecological or biogeographic criteria. The journal also publishes book reviews. Articles published in Ostrich are expected to be of value to ornithologists, ecologists, conservationists and interested bird-watchers.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
