It's flexible
You have complete control over which species you learn. Focus on orioles and blackbirds, on sparrows of the open field, or even set up a playoff between Townsend's and Hermit Warbler.
Unique audio collection
Larkwire's audio collection is
unparalleled, both in depth and quality. Drawing on the renowned collections of the
Macaulay Library (Cornell) and the Borror Lab (Ohio State), we
typically have at least three (but often many more) examples for
each type of song or call, so that you learn the species not a
particular bird.
Just as important, every sample has been digitally mastered to remove
artifacts such as background sounds. Most audio collections leave these in,
but removing them is essential for learning. Otherwise, you're almost certain
to rely on artifacts when trying to distinguish confusing sounds.
