Dusky-headed Parakeet, Weddell's Conure, Dusky-headed Conure (Aratinga weddel
What an amazing photo. I was searching for the Parakeets that were hidden in some sort of green helliconia and then, realised that the "green helliconia" was the Parakeets.
It was an amazing place. The Parakeets come every day to this clay bank, which the eat from to get some vital mineral. Another such spot had 5 or 6 different parrot species coming for the same purpose.
A number of parrots eat clay to neutralise/absorb toxins in some of the seeds they eat.
