Yes, you now know heaps about the goldfinch brain. And you know the equipment specs for the goldfinch brain.
BUT … you are now starting your own research program, and goldfinches do not do the behavior you propose to study. Or you are doing development now, and goldfinches do all their, relevant to your work, development in 16 minutes, which inevitably happen at 3:30am.
So… before you get trapped into goldfinches, look around and see if larks, or eagles, or better yet, emus suit your own program a bit better. Chose your species with care.
