There is little information on birding hotspots although all the IBAs should offer excellent birdwatching opportunities.
For example, in a 19 day study of the avifauna of Parque Nacional de Monte Alen in Rio Muni, Bob Dowsett and Françoise Dowsett-Lemaire recorded 248 species. A remarkable 72 species were additions to the national list (29 of which confirmed previously doubtful records). A full discussion of the area’s avifauna, complete with a coded checklist, appears in a recent issue of Alauda; the authors also report on a number of other additions and deletions to the country’s avifauna since the publication of their checklist in 1993, see DOWSETT-LEMAIRE, F. & DOWSETT, R. J. (1999).
