Yes, tropical bird stomach acid is 0.1 to 0.3 pH whereas human gastric acid is in the range 1-2 pH. Fresh lemon juice is around 2.25 pH (not Meyer's Lemon, which is Lemon x Orange).
There is a community of researchers trying to simulate digestive actions on seeds for germination. The last article I read concerned folks trying to save tree species on islands where the bird population had been hunted to extinction. The islands are becoming barren because the seeds will apparently not germinate without the birds and the existing trees are dying of old age.
