069. ‘AYE AYE’. Cocoi Heron. Pantanal, Matto Grosso, Brazil
The cocoi heron is similar in appearance to the grey heron, but the former has a slightly darker colouration and a longer neck and crest. The activity taking place on the head of this cocoi is not a threat but may be irritating. Alongside human interference, the one natural threat may be posed by the southern crested caracara.
