ELI5 - How come there aren't as many owls out there as there are crows, seagulls, robins, and other common birds.

I can recall one time in my life I seen an owl.

A couple of reasons.  First, an owl is a carnivore, and any particular ecosystem can support far fewer carnivores than other types of organism - there really are fewer owls than, say, omnivores like the seagull.  But also, most owls are nocturnal.  They're out at night, where you aren't.  Add those things together, and the fact that they mostly avoid populated areas, and you've got an owl sighting as a fairly rare event.
