 abstract={Contents of 30 stomachs of 3 swift species, and 97 stomachs of 9 swallow species have been analyzed. Most birds were shot during the breeding season in semi-arid grasslands of South Africa. Swifts fed mainly on termite alates and minute nemathoceran Diptera, while swallows preyed mainly upon minute Coleoptera.
