The vast majority of these seeds were passed without obvious physical damage; in many cases, fruit tissue was still attached to the seed, indicating gentle treatment in the hornbill gut. Our results suggest that the quality of hornbill seed dispersal might be poor at nest trees due to the highly concentrated seedfall, which results in high seed and seedling mortality. Edible birds' nests, beeswax, feathers of birds of paradise, and hornbill ivory were also in demand as were products from the mangrove forests such as cutch and nipah. The mountainous forests of the preserve harbour large number of silver hornbills, buffalo and herds of wild elephants.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Of 102 fruits fed to the captive hornbills, exact seed passage times were recorded for 92 (90%). Because of the necessity of recording conspecifics, average presence values overestimate the actual presence of hornbills, probably by a large margin. Recruitment and invasion: do hornbills facilitate the invasion process? From this perspective, hornbills provide better seed dispersal services than squirrels. Because the route of seed passage (defaecation or regurgitation) was unknown for most seeds, all seeds collected from hornbills were grouped for analysis. Seeds passed by hornbills were collected opportunistically during feeding observations (1994 plantings) or from nest traps (1995 plantings). Thus, these nests were also considered as being affected by seed dispersal by hornbills in 1999. Since seed regurgitation by hornbills usually continued for 10-20 min, the median time was reported for each observation session. On average, hornbills dispersed > 26 times more seeds than monkeys, and > 3 times as many seeds as turacos per visit and were thus considered the most important disperser. Thus, we presumed that the seedlings of diet species that emerged in 1998 and 1999 germinated from the seeds dispersed by hornbills in the breeding season of the same year. In addition to direct diet observations, hornbill diet was sampled during the nesting season via seed trapping at nest cavities. However, during the 4-6 mo nesting season, large numbers of seeds accumulate beneath hornbill nest cavities. Identifications of insects in hornbill diets were limited to the family or order level. Collectively, the three hornbill species consumed fruits from 59 tree and liana species, and likely provided dispersal for 56 of them. The pattern and consequences of hornbill seed dispersal at nest sites is likely very different from that during the non-breeding season. These examples are from corpora and from sources on the web.
