NOTES: (Breeding Status: Territorial. Stimulus for Sound: Natural; after initial natural, then playback. Sound Delivery Rate: Normal, high. Gen. Climate: Cyclic wet-dry. Gen. Habitat: Wooded grassland. Cover Density: Medium.) Stop along road in semi-open woodland with grass above Sand Lake [word obliterated by three-hole punch]. Hear what sounds like L. bidentatus but different, longer, and repeated. This at 8:20+. At 0845 move car to E side rd. because of several cars passing. I glimpse flying vaillantii. Playback of new "didididididi---" notes causes strong following action by one vaillantii. The song varies in tempo, also in wavering quality. Singer has crest partly up. Bill wipes as searches for playback bird. Follows me about, very close, allowing pictures and seeing me playback. 0930 - two together, only one sings. Bill open, crest partly up, hackles raised, head forward, gives series after series of 3-4 sec. up to 20 sec. each with but briefest pause between them (maybe because other birds have similar notes, so it gives long series of varied lenghts within series). Song like rattle of erythrocephalus and like usambiro song. As one sings other pecks branch, preens self, then preens singer's rump. As it does so, song wavers. No song from bird 2.
Continues to follow me about for one hour, singing in bursts. Flight floppy, very like erythrocephalus or like purpuratus when in open. Bill like purpuratus.
Twice more get two birds, but second bird neither duets nor stays long at site, goes off, leaving singer singing for five minutes or more.
