His passion for birdwatching began when he saw the Procnias nudicollis (Bare-throated Bellbird) in person for the first time at Mbaracayú Lodge in 2017, an experience that changed his perspective on birds and sparked a genuine curiosity about them, their behaviors, and the environment in which they live.

Born in Puerto Iguazú, Argentina, city of the imposing Iguazu Falls and the great Atlantic Forest. He is an innate naturalist, birds have been part of his life long before he was born. His family has a project of more than 30 years called the Garden of Hummingbird installed in this iconic tourist city, it has become one of the great attractions of Puerto Iguazú and is one of the most visited . In the garden of his house Leandro lives daily with hundreds of hummingbirds of several more than 8 species and many other species of birds.

The passing of his life among free birds has made him a great defender of conservation and an expert observer, he dominates the jungle and the songs of the colorful birds of the Atlantic Forest, all his innate gifts of birdwatchers, his knowledge of plants , animals and insects, besides being a wonderful human being who loves his nature and showing it to those who visit him, makes him a great companion.
