Egretta vinaceigula occurs in Zambia (perhaps 500-1,000 birds, notably at Liuwa Plain, Kafue Flats and Bangweulu in some years, although breeding not recorded [R. J. Dowsett in litt. 1999, 2000, P. Leonard in litt. 1999]), northern Botswana (probably over 2,000 birds [S. J. Tyler in litt. 2007], mostly around the Okavango Delta and Chobe river, where breeding occurs in at least 12 heronries [S. Tyler in litt. 2012]), and northern Namibia (c.300 birds [R.E. Simmons and C. Brown per Hancock et al. 2006a], especially along the Chobe floodplain and Caprivi Strip). It wanders more widely when not breeding (M. Herremans in litt. 1999), and possibly occurs sparsely in Katanga in the Democratic Republic of Congo, in Zimbabwe, and occasionally South Africa. It is expected to occur in Mozambique (its presence on the Zambezi Delta is unconfirmed [Parker 2005]), Angola and possibly Malawi. The species is nearly always encountered in small numbers, e.g. rarely more than c.100 together in Zambia (R. J. Dowsett in litt. 1999, 2000), and it is likely that the Okavango Delta/Lake Ngami population is in excess of 2,000-3,000 birds, with a world population of c.3,000-5,000 birds (R. J. Dowsett in litt. 1999, 2000, Tyler 2011).
