Looking for opinions from those knowledgeable about Piping-Guans in the Pantanal. I've been told that there are red throated forms of Blue-throated, and that is what this may be. However, many sources show Red-throated Piping-Guans from this area with a bicolored wattle like this one. This seems to be at the southern edge of the range of RTPG. Hybrid, RTPG, BTPG, unknown? Any detailed knowledge or references would be greatly appreciated.
