Characteristics edit
Although most species eat only insects, they also consume fruit (usually berries), worms, and land snails. Many species live in warm climates year-round, while others travel large distances during the summer to migrate to higher latitudes. [2].
Thrushes build cup-shaped nests, sometimes lining them with mud. They occasionally lay two or more clutches of speckled eggs annually, laying two to five eggs total. Both parents help in raising the young. [2] The nest is usually perched on a branch; the three species of bluebirds that nest in holes are the only exceptions.
Ecology edit
Plant seeds are dispersed by Turdidae species, which aid in the recovery of ecosystems and the dispersal of numerous species.
Due to their restricted ability to disperse their seeds far from their parent plant, plants depend on a range of dispersal vectors, including both biotic and abiotic vectors, to carry their propagules. Seeds can be dispersed in time and space, either individually or collectively, and away from the parent plant.
Fruits are an important source of nutrition for a large number of bats and birds, including those in the families Cotingidae, Columbidae, Trogonidae, Turdidae, and Ramphastidae. These animals eat fruit and swallow the seeds, which they later pass in their feces or regurgitate. One important mechanism for seed dispersal across ocean barriers has been such ornithochory.
Some seeds have the ability to adhere to the feet or feathers of birds, allowing them to fly great distances. After such lengthy travels, grass seeds, algae spores, and mollusk and other invertebrate eggs frequently settle in isolated locations. Because some populations of Turdidae migrate great distances and disperse the seeds of endangered plant species at new sites, the family plays a crucial role in the ecology by preventing inbreeding and enhancing the genetic diversity of the local flora.
