We analyze whether biodiversity is increasing the receipts of tourism and thus is beneficial for developing
countries (DCs). The underlying assumption is that a rich biodiversity provides a comparative advantage for most DCs.
We use a simple trade theory framework. The model is supported by an empirical analysis. The main findings are that first
DCs, being abundant of biodiversity, seem to have a comparative advantage in (sustainable) tourism, that second incidence
of birds as the probably best explored taxonomic group has a positive impact on inbound tourism receipts per capita,
and that third the rate of endangered to total birds is negatively influencing tourism receipts. We draw some cautious
