Range DescriptionMalimbus ibadanensis was known only from a small area circumscribed by Ibadan, Ife, Iperu and Ilaro in south-western Nigeria (Elgood et al. 1994). In December 2006, the species was discovered in Ifon Forest Reserve, where six sight records were obtained during a 10-day survey (A.U. Ezealor in litt. 2007, Ajagbe et al. 2009). Foraging pairs were seen on two separate occasions and lone males were recorded twice (A.U. Ezealor in litt. 2007), and there were further records from the reserve in 2007 and 2008 (Anon. 2008). Records of this species from Kakum National Park, Ghana, in February 2002, September 2004 and February 2005 are yet to be confirmed (R. Cruse in litt. 2005, R. Thomas in litt. 2005, L. Fishpool in litt. 2005). Between the 1970s and early 1990s there were very few records (Ash 1991). It was not seen from 1980 until November 1987 (Elgood et al. 1994), when only four birds were recorded in 10 days of intensive searching at Ibadan. Records in the late 1990s were all from the grounds of the International Institute of Tropical Agriculture (IITA) near Ibadan, as searches were concentrated in this area (P. Hall in litt. 1999). Nine birds (two pairs and five females) were seen there between October 1998 and April 1999 (plus one female at Akanran, 15 km east of Ibadan) (P. Hall in litt. 1999). Transect surveys were conducted in 1999-2002 at a total of 52 forest patches in south-west Nigeria (Manu et al. 2005, Peach 2005), and on the basis of the results the population was estimated at 2,469 individuals (95%CI: 1,401-4,365) in 112 km2 of remaining forest (Manu et al. 2005). This can be considered a reasonable maximum estimate of the world population since the survey covered almost all remaining forest fragments within the species's historical range (Manu et al. 2005). It was found at only 19 of the 52 sites surveyed (Manu et al. 2005, Peach 2005) and the results suggest that the species's range in south-west Nigeria has declined by c.66% compared with its range in the 1950s-1970s (Manu et al. 2005).
