The reserve is a beautiful place to live and work, and we count ourselves very lucky that we’re able enjoy every minute of both. Every day is crammed with challenges, but the reward that lies in seeing these animals prosper more than pays for every blister and sore back. These snippets give you an idea of what it’s like to be here.

Bare-faced Curassows at reserve

15/04/2026
After an absence of seven years, Bare-faced Curassow have returned once again to Reserva Don Luis. The reintroduction project is being led by Rewilding Argentina, who are making use of the purpose-built corrals we constructed for this species in 2014.
There are currently four birds at the reserve, all males, and they are expected to be released into the reserve within the next week or so.

Team Ibera Seedeater

Day 1 of our project to locate the Ibera Seedeater, carry out bird ringing and later in season search for nests. 5 of us set off on horseback, which is the best way to get around Reserva Don Luis, to search for the Ibera Seedeater. We place coloured streamers where we see the birds and take GPS co-ordinates so we can more easily locate future nests.

This is our main target species. The EN Ibera Seedeater has recently been upgraded to NT, possibly helped by our conservation efforts. We have started our bird ringing before the birds start to nest as part of our project sponsored by Mohamed bin Zayed Species Conservation Fund. We have come across plenty of this species during the past week.
