[6] The citron-throated toucan is found from northern Colombia into northwestern Venezuela.

[6] The citron-throated toucan typically forages from the forest mid-storey to its canopy but will pick up fallen fruit from the ground.

Its diet is primarily a wide variety of fruits and also includes insects and other arthropods, lizards, and birds and their eggs.

[6] The citron-throated toucan's breeding season appears to include at least January to July.

Its breeding biology is assumed to be similar to that of the channel-billed toucan but no studies have been made.

It is considered scarce and local in Venezuela "where its Andean foothill habitat around [the Lake] Maracaibo basin is fast disappearing".
