“…The lower species richness found in the mixed forest is in accordance with the idea that food limitation plays a role in causing some birds to migrate, which leads to species that depend on more seasonal resources to move more (Boyle et al 2011, Ryder & Sillett 2016, Macario et al 2017, Miller et al 2021. Seasonal variation in fruit abundance has been found in different areas of the Atlantic Rainforest (Malizia 2001, Castro et al 2007, Pinto et al 2021, and is likely to be linked to the decrease in niche occupancy associated with the consumption of fruits in winter in the mixed forest.…”

Seasonal variation in tropical and subtropical systems can have different effects on bird species depending on the resources they use and how they use them. However, despite recent research advances, knowledge of the drivers of the presence and abundance of species in different seasons is still limited for most tropical bird species. In these poorly understood systems, examining seasonal changes in species composition from the perspective of traits related to resource use can provide insight into what resources may be driving bird movements between areas throughout the year and what types of species are more subject to seasonality. Here, we explore bird community seasonality in three forest types (dense, semi-deciduous and mixed rainforests) subjected to different climatic conditions in one of the world's biodiversity hotspots, the Atlantic Rainforest. We investigated differences between summer and winter in species richness and in the composition of resource-related species traits (diet, foraging strata and substrates) obtained from the literature. The seasonal differences (summer and winter) between forest types were explored in terms of species and trait composition. We found that the main changes that occurred in bird composition between seasons in the southern Atlantic Rainforest were related to species traits such as diet and foraging strata. In general, the proportion of invertivores was higher in winter than in summer, and in the mixed forest, the forest type exposed to the coldest winters, the proportion of frugivores was lower in winter. Furthermore, species with a more varied diet were better represented in the summer. In general, more generalist species were better represented in the forest type subjected to higher seasonal variations in rainfall. Our results revealed seasonal changes in bird community structure that are related to niche occupation and that were more strongly apparent in the forest type subjected to colder winters.

“…1995; Ryder & Sillett 2016; Macario et al . 2017). The tendency for plant‐dependent bird species to have greater seasonal movements across the landscape, and their propensity for boom‐bust population dynamics, could result in episodic reticulation of otherwise isolated populations, in effect ‘resetting the clock’ for differentiation time.…”

Demographic consequences of foraging ecology explain genetic diversification in Neotropical bird species

et al. 2021

Despite evidence that species’ traits affect rates of bird diversification, biogeographic studies tend to prioritise earth history in Neotropical bird speciation. Here we compare mitochondrial genetic differentiation among 56 co‐distributed Neotropical bird species with varying ecologies. The trait ‘diet’ best predicted divergence, with plant‐dependent species (mostly frugivores and nectivores) showing lower levels of genetic divergence than insectivores or mixed‐diet species. We propose that the greater vagility and demographic instability of birds whose diets rely on fruit, seeds, or nectar  known to vary in abundance seasonally and between years  relative to birds that eat primarily insects, drives episodic re‐unification of otherwise isolated populations, resetting the divergence ‘clock’. Testing this prediction using coalescent simulations, we find that plant‐dependent species show stronger signals of recent demographic expansion compared to insectivores or mixed‐diet species, consistent with this hypothesis. Our study provides evidence that localised ecological phenomena scale up to generate larger macroevolutionary patterns.

“…While arthropods are certainly subject to population cycles, they are usually less extreme (Jahn et al . 2010) than the fluctuations between mast years and lean years in fruit and seed-bearing species typically relied on for food by frugivorous and granivorous birds (Faaborg, Arendt, and Kaiser 1984; Wheelwright 1986; Levey, Moermond, and Denslow 1994; Brawn, Karr, and Nichols 1995; Ryder and Sillett 2016; Macario et al . 2017).…”

Defining phenotypically similar populations as separate cryptic species can provide insights into the speciation process, as the taxa in question are often in the early stages of speciation. Here, we identify potential cryptic species based on a comprehensive dataset of COI mitochondrial DNA barcodes from 2,333 individual Panamanian birds across 429 species, representing 391 (59%) of the 659 resident landbird species of the country, as well as opportunistically sampled waterbirds. We complement this dataset with additional publicly available mitochondrial loci, such as ND2 and cytochrome b, obtained from whole mitochondrial genomes from 20 taxa. Using barcode identification numbers (BINs), we find putative cryptic species in 19% of landbird species, highlighting hidden diversity in the relatively well-described avifauna of Panama. Whereas some of these mitochondrial divergence corresponded with recognized geographic features that likely isolated populations, such as the Cordillera Central, the majority (74%) of lowland splits were between eastern and western populations. The timing of these events did not coincide across taxa, suggesting that historical events, such as the formation of the Isthmus of Panama and Pleistocene climatic cycles, were not the primary drivers of speciation. Rather, we observed that forest species, understory species, insectivores, and strongly territorial species- all traits associated with lower dispersal ability- were all more likely to have multiple BINs in Panama, suggesting strong ecological associations with divergences. Additionally, hand-wing index, a proxy for dispersal capability, was significantly lower in species with multiple BINs. These results suggest that dispersal ability plays an important role in generating diversity in Neotropical birds. Together, these results underscore the need for evolutionary studies of tropical bird communities to consider ecological factors along with geographic explanations, and that even in areas with well-known avifauna, avian diversity may be substantially underestimated.
