A case of Straight-billed Reedhaunter (Limnoctites rectirostris: Furnariidae) nesting in Teasel (Dipsacus fullonum: Dipsacoideae)

I present a case of a Straight-billed Reedhaunter ( Limnoctites rectirostris ) nesting in Teasel ( Dipsacus fullonum ), an exotic plant widely distributed in the study area in northeast of Buenos Aires province, Argentina. Limnoctites nests specifically in Eryngo ( Eryngium ), however I show here that it may also nest in other plants with fairly similar (thistle-like) characteristics, when in close proximity to Eryngium . The nest, active with one egg and two chicks, was destroyed by a rainstorm which toppled the Teasel. Since the structure did not fall completely to the ground the nestlings initially remained alive, but eventually perished, although the nest was not destroyed.
