This 18 December 2018 video says about itself:
The resplendent quetzal bird from the trogon family calls home the mountain range of Talamanca in Costa Rica. This stunning looking bird feeds off wild avocado among other fruits. Footage was filmed in the wild in the San Gerardo de Dota area of the Talamanca.
I was privileged to also see resplendent quetzals at their nest there.
