Sn. Bouton et Tc. Bouton, Interspecific interactions and nest building behavior in Buff-necked Ibis in the Brazilian Pantanal, WATERBIRDS, 24(2), 2001, pp. 294-295
We report for the first time on Buff-necked Ibis (Theristicus caudatus) gre
eting and courtship displays during nest building. Displays included both i
ndividual and simultaneous Up-down Displays and Stick Shaking. The nesting
attempt was brought to ail abrupt end, apparently by interactions with Cres
ted Caracaras (Polyborus plancus) and/or interspecific competition with woo
d Storks (Mycteria americana) for nest material.
