I have a question/theory on a curious observation in my yard. Various birds come to my bird feeders, except of course the non-seed-eating birds. However, there is one species of seed eaters that I never see at my bird feeder, rather they prefer to eat the seeds directly off the plants, both cultivated and wild plants. It's the House Finch.
I have noticed that they seem to eat the seeds that are not totally mature, rather still a little green, so I'm guessing/theorizing that House Finches like non-mature seeds. Anyone know if this is true?
Here's some pics I took the other day of them eating seeds from my Florida Broadleaf Mustard plants.
