Fruit characters in the diet of syntopic large frugivorous forest bird species in French Guiana

Abstract: Les caractères des fruits consommés par les grands oiseaux frugivores syntopiques en forêt guyanaise française. — Les caractéristiques des plantes sur lesquelles les quatre grandes espèces frugivores aviennes de Guyane française (Tinamus major, Tinamidae ; Psophia crepitans, Psophiidae ; Crax alector et Penelope marail, Cracidae) basent leur régime alimentaire ont été analysées. Les caractéristiques de 102 espèces végétales et de leurs fruits ont été comparées afin de détecter d’éventuels syndromes propres à c… Show more

“…This is a key determinant of biodiversity distribution in tropical forests as it is correlated to a range of biotic and abiotic variables including water availability, soil and vegetation characteristics, and microclimate (de Castilho et al 2006, de Toledo et al 2011, Norris et al 2014. The negative effect of elevation on trumpeter occupancy may relate to higher humidity and productivity in lower-lying areas; trumpeters prefer the moistest parts of the forest for foraging (Erard et al 2007) and tend to be more abundant at sites closer to water (Michalski et al 2015, Paredes et al 2017, Mere Roncal et al 2019, del Hoyo et al 2020. Such habitat specificity probably increases the species' vulnerability to climate change.…”

“…Perhaps early successional or disturbed forests lack essential resources. For example, disturbed areas have fewer large trees, which provide the bulk of fruit consumed by trumpeters (Erard et al 2007), and may lack trees with appropriate cavities for nesting (Sherman 1995a, Cornelius et al 2008). Dense understorey in disturbed areas may also hinder communication and vigilance.…”
