NOTES: Neotropical Institute Cut #94. Bulk reel #524 The description given is for the bird that responded to playback of a), and it did respond very actively. (See also general note of this date.) a) 8:20 AM. Natural song. (Medium to heavy mottling, with "tiger striping" on sides, no visible white crown.) Quality: 2. Level: +2, 0. 3.75 ips. 203 tape. LN. Sporophila intermedia and Volatinia jacarina are heard prominently. b) This is believed to be same bird (and almost surely is) a long time (~ 30') after any playback. Quality: 1. Level: 0, +3. 7.5 ips. LN? Std? (By error this was recorded with Std. equal.) c) 9:05 AM. Presumably and probably (to judge from its rattle), the same bird. Also it looked like the same bird. Quality: 1. Level: +3. 7.5 ips. LN. Collected. In this part the bird begins to use "complex" (= long) phrases. The "complex" part ofo the phrase is rather different from normal, including other birds in this region; however, it may be this ~ "warbled" variation that I heard last year at Site 1 (cf. note of 4 Oct 1973 on back of editing sheet for Cuts 61/63. Note that after b) was recorded the bird left, apparently to forage elsewhere. After a while I heard it, or a bird, sing from some 30 m. away. I think that was this bird, for it then sang briefly, or at least this bird did, from a couple perches closer and finally took a perch high in the tree where I was standing and sang there for a long time, resulting in c). Just after the last phrase of c) the bird again left, again presumably to forage somewhere. After some t ime I heard it singing in a tree some 15 m. away as I began some playback experiments, the notes about which are on the general notes for this date. d) 9:40 AM. Weather: Cloudy, fair. Same bird after playback experiments. Quality: 1. Level: +3. 7.5 ips. LN. After the playback experiments the bird sang mostly short phrases. After some time it did begin to inject partially developed long phrases (usually when I was not recording!). Bird was then collected = male #[blank]. Note that this bird's rattle phrase is rather like a Furnarid rattle (Asthenes wyatti, Certhiaxis cinnamomea).
