Welcome to The Bird Song Data
Currently trying to explore BirdWeb for their song library but wirelesspittnet is failing me per usual
I Found an a song base from Arizona Field Ornithology. This is the link to the finch tag, which is labeled “Fringillidae – Finches and Goldfinches” which I’m not sure is one of the species we are interested in.
I’m having some trouble finding info on galapagos finches specifically, I have another link to bird song but its again mostly house finches.
Cool article about how the shape evolution of the beak also caused song to evolve: Science Daily
