    Equipment Note

NOTES: Songs and calls by a pair of birds, both of which were well seen (the female especially so); the birds were as near as 2 m and as far as 10-12 m, and from ground level to 2-2 1/2 m up; all recordings followed playback, initially of a prerecorded tape Jeremy had made in Santa Catarina, later of themselves; birds vocalized only in response to playback, and typically only briefly before going quiet again; they (especially the female) approached aggressively and at close range, often silently, but they eventually sang; the male and female gave somewhat different songs with the higher Òchick-itÓ songs apparently given by the female, and the shorter ÒchickÓ by the male, which was not nearly as vocal or as responsive; we eventually concluded that our initial playback tape probably represented the female song; these birds were in an extensive marsh clogged with 3 m-tall Typha located at edge of a rural neighborhood and farmland in a large river valley, where they had been released after being moved from another site that was being inundated for a reservoir; the marsh was dry at the time, with trails cut through the Typha, apparently to aid researchers studying the birds; recording simultaneously with Jeremy Minns; almost completely clear, with wind dying down at end of our visit, and 85-87¡F (if thermometer hadn't been cooked) [= SPA260-266].
