- Description: Ringing activity in the Eastern Cape province, South Africa, spanned 30 years, with three sites active concurrently over a 14-year period, and three sites over a 6-year period. In total, in the course of 714 ringing days, in all months, we handled 1 207 Amethyst Sunbirds, 708 Southern Double-collared Sunbirds, 707 Greater Double-collared Sunbirds, 381 Grey Sunbirds, 121 Malachite Sunbirds and 140 Collared Sunbirds. Although individuals of all six species were recaptured more than five years after ringing, and despite evidence of the seasonal passage of sunbirds at two sites near the Indian Ocean coast, no birds were recaptured away from the original ringing site.

- Description: Almost all our records of green-bellied Cape White-eyes are outside the breeding season, with a peak in winter. They possibly come from localities to the east of Grahamstown, Bathurst and Port Alfred, but we have no direct evidence of such movement, nor of altitudinal migration between coastal and inland sites. The higher frequency of green-bellied birds at the coastal ringing sites may suggest local movements within the coastal belt, or occasional coastwards movement by adjoining populations, which could also account for the diversity of flank colours recorded in a small proportion of the birds.
