The vampire earthquake on the Galapagos Islands is more interesting than turtles

The bird is referred to in Hungarian as the somewhat nonsensical tufted earthhead, although its English name, the vampire earthquake, tells much more about its non-everyday habits. Because the name is not deceptive: this bird is really hitting larger birds and then eating their blood. Researchers at the University of California at San Diego have now discovered that the bacteria in their intestinal flora are very similar to those of the vampire bats.

ORGANIZED LIVING BACTERIA IN ANIMAL ORGANIZATION TO ENJOY THE CLEANER LIFE.

But let’s start at the beginning. In studying the many species of finches present on the Galapagos Islands, Charles Darwin discovered that species from the same ancestor were modified to meet the needs of the environment, and that they became different species. In the case of finches, this is the most accurate follow-up of the bodily shape adapted to their diet.

In the harsh half of the year, the dwarf-earthed dwarf does not really differ from the pattern expected of finches: seeds, fruits, sometimes insects, or nectar. But as the dry season comes in, and the plant’s diet decreases, it moves to blood sucking. His favorite victim is the bird named sula granti (this is the Hungarian name), which jumps to his back, then traps his wing and drinks the blood of the spit.

THE ENVIRONMENT IS WELL IN THE MORE GROUND SANDS AND WELCOME TO THE SERIES.

For the digestion of blood, special bacterial flora can be found in the gastrointestinal tract. Now, researchers have discovered that these bacteria are very similar to those of vampire bats in breeders. That is, we are facing a convergent evolution: the characteristics of otherwise non-related species have become similar to similar environmental constraints. Similar convergent evolution can be observed in the intestinal flora of species with special nutrition, for example, eating only ants.
