Whether a bird handles a fruit by crushing it with its bill or simply swallowing it whole has important ramifications for both the dispersal success of the plant and the feeding behavior of the bird. In cage experiments, birds that crushed fruits in their bills ("mashers") usually dropped many seeds without ingesting them. Large seeds were dropped more frequently than small seeds. The proportion of seeds dropped by five tanager species correlated negatively with their body weight. Birds that… 
Birds and guelder rose Viburnum opulus: selective consumption and dispersal via regurgitation of small-sized fruits and seeds
TLDR
Investigation in guelder rose Viburnum opulus (Caprifoliaceae) fruit consumption by birds in an area in NW Spain found that the largest fruits were consumed less by seed-dispersing birds and were exposed to seed-predators (bullfinches and climbing rodents) for longer.
Benefits to the germination of seeds provided by birds that mandibulate fleshy fruits
TLDR
Bird processed seeds germinated in equal proportions than manually extracted seeds, and most of the retrieved seeds processed by these birds were defecated, and a large percentage of them germinate, which confirms that they are important for the seed dispersal process.
Foraging ecology of avian frugivores and some consequences for seed dispersal in an Illinois woodlot
TLDR
A 3-year study of interactions between frugivorous birds and fleshyfruited plants with bird-dispersed seeds documented the diffuseness of the mutualism between the taxa, and the most efficacious dispersal agents were not necessarily the most common dispersers of any of the plants.
IMPORTANCE OF SEED INGESTION TO AN AVIAN FRUGIVORE: AN EXPERIMENTAL APPROACH TO FRUIT CHOICE BASED ON SEED LOAD
TLDR
When captive Silvereyes were presented with a cereal-based diet containing artificial seeds, they avoided seed ingestion and were able to consume proportionally more cereal than seeds, even when on a high seed-load diet.
Seed‐swallowing Toucans are Less Effective Dispersers of Guettarda viburnoides (Rubiaceae) than Pulp‐feeding Jays
TLDR
During 3 yr, species-specific quantitative and qualitative aspects of Guettarda viburnoides seed dispersal by avian frugivores are examined, focusing on how these aspects modify seed disperseal effectiveness.
DOES SEED PACKAGING INFLUENCE FRUIT CONSUMPTION AND SEED PASSAGE IN AN AVIAN FRUGIVORE?
TLDR
It is argued that the response of a facultative frugivore, the Silvereye, to fruit containing different forms of seed packaging facilitates plasticity in the diet and the processing of insects when fruit is not available.
Fruit size in wild olives: implications for avian seed dispersal
TLDR
This study shows that heavy dependence on fruit is not always simply related to seed dispersal, and the same frugivorous bird species can act as a seed disperser or a pulp predator for the same plant species.
How Long do Fruit-eating Birds Stay in the Plants Where They Feed?'
TLDR
Data is presented on the behavior of four bird species which were responsible for more than 94 percent of all feeding visits to eight bird-dispersed tree species in the family Lauraceae in the lower montane forests of northwestern Costa Rica to indicate that fruits may not be the "free lunch" they are often reputed to be.
Diets of fruit-eating birds: what are the causes of interspecific differences?
TLDR
The available evidence indicates that the European bird species that show stronger preferences for lipid-rich fruits are no better as seed dispersers, from the point of view of the plants, than species choosing lipidpoor fruits.
Alternative seed-handling strategies in primates: seed-spitting by long-tailed macaques (Macaca fascicularis)
TLDR
It is suggested that fruit storage in the cheek pouches of cercopithecine monkeys allows them to spit seeds individually without excessively slowing fruit intake while feeding on patchily distributed fruit.

BIRD ACTIVITY AND SEED DISPERSAL OF A TROPICAL WET FOREST TREE
TLDR
It is hypothesized that extinction of this plant at this site would lead to disappearance of these birds, and would almost certainly depress recruitment of other species of trees for which they serve as dispersal agents at other times of the year.
MONKEY DISPERSAL AND WASTE OF A NEOTROPICAL FRUIT
TLDR
Wide geographical ranges of this tree and members of the frugivore assemblage, use of other food resources by common foragers, richness of the assemblages, variation in species visitation at individual trees, irregular annual fruit production, and obvious "inefficiency" of the dominant dispersal agents from the perspective of the plant suggest that Tetragastris has a generalized dispersal strategy.
Fruit‐Size, Gape Width, and the Diets of Fruit‐Eating Birds
TLDR
The results suggest that fruit—eating birds face many of the constraints imposed on other gape—limited foragers, but have an unusual minimum—size relationship with their food because of the unique characteristics of fruits.
EVOLUTION OF TEMPERATE FRUIT/BIRD INTERACTIONS: PHENOLOGICAL STRATEGIES
TLDR
This paper compares the removal rates of mid-latitude fruits before, during and after fall bird migrations, analyzes seasonal variation in the ripening patterns of plants in the context of frugivore availability, and provides a theoretical framework for future work on the phenology of temperate fruit/bird interactions.
Early Consequences of Seed Dispersal for a Neotropical Tree (Virola surinamensis)
TLDR
The results demonstrate clear advantages to local seed dispersal for a tree of the rainforest canopy and suggest that dispersal of seeds > 20 m by large birds, such as guans and toucans, is more favorable for seedling survival than that of the smaller trogons and motmots, which regurgitate seeds under or near the tree crown.
Fruit variation and competition for dispersers in natural populations of Smilax aspera
TLDR
Multiple stepwise regression analysis shows that the best single predictor of the mean number of seeds per fruit is the number of plant species bearing fruits simultaneously and equally or more abundant than S. aspera, suggesting that observed variation in fruit seed numbers must be attributed to interspecific competition for dispersers among plants.
GUANACASTE TREE SEED-SWALLOWING BY COSTA RICAN RANGE HORSES'
TLDR
While seed spitting undoubtedly lowers the quality of horses as guanacaste seed dispersal agents, the high frequency of seed spitting does not mean that the horse is necessarily a "poor" dispersal agent.
Tropical fruit-eating birds and their food plants: a survey of a Costa Rican lower montane forest.
In the lower montane forests of Monteverde, Costa Rica, at least 70 bird species rely on fruits to different degrees. We present over 700 records of birds feeding on the fruits of 171 plant species
SUGAR-TASTING ABILITY AND FRUIT SELECTION IN TROPICAL FRUIT-EATING BIRDS
The sugar-tasting abilities of four species of tanagers and two species of man- akins were tested. Three tanager species were able to detect differences in diets containing 8%, 10%, and 12% sugar. In
