found and ID first by Mark Peterson. Breeding plumage. Compared to PALO the ARLO had blocky head compared to slender shorter bill of PALO with shorter more rounded crown.. Wide white rear flank patch and at times white extended across lower flank which is fine for ARLO. when not gazing into water or diving bill was displayed a bit above horizontal. Dark gray nape and crown and blackish throat. Look at Glenn Walbek's photos.
