Hábitat y abundancia de Coturnicops notata y Porzana spiloptera en Mar Chiquita, prov. de Buenos Aires, Argentina
We provide new records, data on habitat and abundance of the Speckled Crake (Coturnicops notata) and Dot-winged Crake (Porzana spiloptera), and measurements and stomach contents of one C. notata. The study area was Mar Chiquita Reserve, Buenos Aires Province. Records were gathered as follows: betwee...
