Talons and sharp eyes to see their prey
There are two owl families..Tytonidae, barn owls, and Strigidae, all other species. Owls are birds of prey.
Earthworms are prey to birds because they are smaller, slower, and are not capable of attacking birds.Also, many birds actually have two foveae in their eyes, while humans have one. The fovea is the part of the eye that is most sensitive and has the most photoreceptors. So with two focal points, such birds have very sharp vision and can see earthworms, among other prey.

Not all naturally occurring phenomenon can or should be interpreted as an omen. Birds of prey are territorial in nature. This means they tend to stay in the same general area most of the time. Seeing a bird of prey two days in a row is not uncommon, in fact, if you travel he same route daily you may continue to seethe bird for most of a season. If you see two different birds, (for example a falcon and a hawk) on two consecutive days in very different places (for example one in your neighbourhood and one where you work), then and only then might this be a sign. The kind of bird, and the circumstance will vary the interpretation.
When vole numbers increase in an area, the owls, and other birds of prey, numbers will also increase - as there is plenty of food to feed their chicks. If the voles become scarcer, the number of chicks able to survive is reduced. Some birds of prey lay two eggs. If there is plenty of prey, both chicks will thrive to adulthood. If the prey becomes scarce, one chick will be given any food the adults can bring, and the smaller, weaker chick will die.
