Trogonidae make up a family of birds with a mixed diet composed of fruit and animal matter. However, there is little research examining the foraging ecology of Trogon citreolus in regenerating tropical forest. We studied T. citreolus abundance and diet from November 2020 to April 2022 in a regenerating dry tropical forest of Central Pacific Mexico....

Context 1
... obtained a total of 41 foraging records of T. citreolus (n = 88 individuals), consuming 14 plant species from 10 families ( Table 1). Only fruit consumption was recorded during the foraging observations, and no other items were consumed. ...Context 2
... fruit consumption was recorded during the foraging observations, and no other items were consumed. The most common plant families in the trogon diet were Anacardiacae (34.1%; n = 19 individuals), Rubiaceae (17.1%; n = 21 individuals), Moraceae (12.3%; n = 24 individuals), and Vitacae (9.8%; n = 6 individuals) (Table 1). ...Context 3
... the plant species listed in Table 1, 57.2% correspond to mature deciduous tropical forest species, while 42.8% are common in regenerating forests (Pennington and Sarukhán 1998;Rzedowski 2006). ...Context 4
... represents a moderate niche breadth where use was spread relatively equally over the resources, with six plant species contributing > 5% of the diet. Nevertheless, three plant species contributed more than 60% of the trogon diets, with more individuals recorded consuming fruits of Ficus cotinifolia (n = 24 individuals; 27.3%), Comocladia engleriana (n = 17 individuals; 19.3%), and Randia gentlei (n = 14 individuals; 15.9%) ( Table 1). The Shannon-Wiener Index showed low food diet diversity (H' = 0.94), and the Simpson Index showed the dominance of a particular type of food (λ = 0.85), F. cotinifolia exhibited the highest frequency of consumption by T. citreolus. ...Context 5

However, we observed the presence of fruits on Ficus cotinifolia and Forchhammeria pallida in January, Passiflora sp. in December-January, and Ampelocissus acapulcensis in March. ...Context 6
... particular, F. cotinifolia and C. engleriana are the species with the highest percentage of consumption by T. citreolus during the dry season on the coast of Jalisco (Morán-Dimayuga 2002), congruent with our finding in tropical regenerating dry forest. On the other hand, 10 plant species have not been previously reported (Table 1), of which R. gentlei, Passiflora sp., and Ampelocissus acapulcensis contribute > 5% to the Citreoline Trogon´s diet. Nonetheless, T. citreolus has the potential to consume these resources owing to the distinct fructification patterns of each plant species within the tropical dry forest of JBPE. ...Context 7
