Abundance of White-fronted Parrots and diet of an urban parrot assemblage (Aves: Psittaciformes) in a green Neotropical city

Urban ecosystems are evolutionarily recent novel environments acting as biodiversity filters. Psittacidae birds considered successful urban adapters mainly due to their generalist feeding and opportunistic behavior, allowing them occupy from cold temperate dry xeric areas. Therefore, it is important understand how these species interact in the environment. We studied interannual (2013–2016) abundance of White-fronted Parrot (Amazona albifrons) Neotropical cities Xalapa Coatepec, Central Veracruz, México. Additionally, we ecology during 13 months 6 parrot detected city Xalapa. The was significantly higher than homogeneous across years. Non-native plants represented 30–41% diets Xalapa, where seeds were most commonly consumed resource. recorded highest richness diet overlap among by end season (April–May). had plant its diet, followed Monk Parakeet (Myiopsitta monachus) Green (Psittacara holochlorus); yet, a specialized dominated two (Grevillea robusta Ficus aurea). three above-mentioned not different null model, overlapped February, April, June, September. an adapter that has successfully expanded geographic range via natural means human activities. invasive currently restricted one park remained stage for many years (i.e., pre-expansion phase). Exotic represent ∼55% woody vegetation, some which have longer flowering fruiting periods may aided establishment environments.
