A multiPhylo list of 50 phylogenetic trees randomly sampled from the
BirdTree Hackett backbone posterior (Jetz et al. 2012), each pruned to the
300 species in avonet300. These trees capture phylogenetic
uncertainty: topologies and branch lengths vary across the posterior sample.

megatrees::get_tree_bird_n100(). Underlying posterior from Jetz
et al. (2012), Hackett et al. backbone.
Details
Use with multi_impute_trees for experimental sensitivity of
point imputations to posterior-tree choice. Tree uncertainty is not
supported by the analysis-aware MI backend, and these stochastic datasets
are not validated for downstream inference.
