Great app, but it needs more frequent taxonomic updates

This is the best bird guide for North America out there, but it doesn't get updated frequently enough. It's been a year since the Warbling Vireo was split into two species and the app hasn't changed yet. There are also a few exotic species that have recently become established that the book does not include, most notably Burrowing Parakeet. A lot of the parrot information in general is outdated as well. And finally, Long-billed and Short-billed Dowitchers could use finer details and maybe some closeups of how the scapular feather patterns differ.
