A SCHEME FOR THE EVOLUTION OF THE MEROPIDAE, AND BIOLOGICAL DATA FOR SOME SPECIES.

The family probably originated in Asian forest and radiated in African non-forest. The bee-eaters not illustrated are Blue-bearded, Nyctyornis athertoni, and White-fronted, Merops bullockoides (bk), Bay-headed, M. leschenaulti (ls), Cinnamon-chested, M. oreobates (ob), Blue-tailed, M. philippinus (ph), Somali, M. revoilii (r), Blue-breasted, M. variegatues (v), and Blue-throated, M. viridis (vd). The bill shape is precise. Refere to Figure 22 for an explanation of insect figures under staple foods. Here the termites represent termites and ants. The mean weight is in grams. Nesters in flat ground or cliffs can be solitary, one tunnel; aggregate, two tunnel; or colonial, three tunnel. A bar means sedentary; an arrow signifies migratory. The number of arros indicates the extent of migration.
